Process Protection System Interface Requirements Specification Revision: 7 Page 3 of 55 1
Introduction 1.1 1.2 Purpose This document specifies the requirements imposed on the Process Protection.System (PPS), its subsystems, and other system components to achieve interfaces among these entities that are required for the PPS to perform its design function.
This document is intended to be revised as the PPS replacement design progresses.
Scope The PPS is comprised of Tricon equipment provided by Invensys/Triconex and Advanced Logic System (ALS) equipment provided by Westinghouse CS Innovations, LLC.
This Interface Requirement Specification (IRS) provides: (1) requirements for the interfaces between external field devices such as process transmitters and the Tricon and the ALS; (2) electrical and communication interfaces between the Tricon and ALS and their associated peripheral devices; and (3) other interfacing Diablo Canyon Power Plant (DCPP) systems such as the Plant Process Computer (PPC), Main Annunciator System (MAS), Safety Parameter Display System (SPDS) and the Safety-Related 120 Vac and 125 Vdc Power Systems.
I All external interface requirements for each of these systems will be defined.
1.3 Definitions and Acronyms 1.3.1 Definitions The following definitions are used in this document:
TERM DEFINITION Channel An arrangement of components, modules, and software as required to generate a single protective action signal when required by a generating station condition. A channel loses its identity where single action signals are combined.

1.5.1 Protection Sets The PPS consists of sixteen (16) racks (per DCPP Unit) of instrumentation located in the Cable Spreading Rooms (Auxiliary Building, elevation 128). The sixteen racks are divided into four Protection Sets; five racks each for Protection Sets I and II, three racks each for Protection Sets III and IV. Each Protection Set is. physically separated and electrically isolated from the other sets. Figure 1-1 illustrates the hardware that comprises the sixteen (16) protection sets.
Protection Set I is comprised of Racks 1 thru 5 (RNP1A, RNP1B, RNP1C, RNP1D, and RNP1E).
Protection Set II is comprised of Racks 6 thru 10 (RNP2A, RNP2B, RNP2C, RNP2D, and RNP2E).
Protection Set III is comprised of Racks 11 thru 13 (RNP3A, RNP3B, and RNP3C).
Protection Set IV is comprised of Racks 14 thru 16 (RNP4A, RNP4B, and RNP4C).
Physical equipment will be assigned to specific PPS racks during detailed design.
The existing Eagle 21 HMI units are located in Racks 5 (RNP1E), 9 (RNP2D), 12 (RNP3B) and 14 (RNP4A). These racks are expected to house the replacement PPS Maintenance Workstation and communications equipment.
1.5.2 Triconex Tricon Programmable Logic Controllers (PLC)
The Tricon PLC shown in the following figures comprises the Main Chassis and two Remote Expansion Chassis (RXMs), all within a given protection set. The Main Chassis is connected to a "Primary" RXM via triplicated copper I/O expansion bus cables. The Primary RXM (PRXM) is connected to a "Remote" RXM chassis using multimode fiber-optic cables. The Remote RXM (RRXM) chassis allows extending the I/O bus over longer distances than copper cables can support, and to provide electrical isolation for non-safety-related I/O signals, as required.
Refer to the Triconex licensing Topical Report [1.4.5.3] for additional information.
1.5.3 CS Innovations Advanced Logic System (ALS) 1.5.3.1 A typical ALS rack configuration as shown in the following figures contains two sets of the following components (See Reference 1.4.5.5 for additional details):
ALS CLB - Core Logic Board ALS IPB - Input Board ALS OPB - Output Board ALS PSU - Power Supply Unit 1.5.3.2 ALS ASU -Auxiliary Service Unit The ASU shown in Figure 1-22 is a dedicated piece of test equipment which can be
Process Protection System Interface Requirements Specification Revision: 7 Page 8 of 55 connected to the ALS rack during diagnostics or testing by plant personnel. The ASU provides non-intrusive diagnostic tools that allow plant personnel to access detailed status and configuration information of the system while the system is online. The ASU also provides post-event analysis information about the system to plant personnel for evaluation of an event after it has occurred.
The ASU can modify setpoints and tuning constants, but cannot alter functional programming (i.e., alter the algorithm) of the CLB.
In the PPS Replacement project, the Maintenance Workstation will perform the functions of the ASU.
1.5.3.3 The ALS A and ALS B conceptual architecture to provide built-in diversity and defense in depth per the D3 evaluation approved by NRC [1.4.5.4] is illustrated in Figure 1-1. Wiring details are illustrated In Figure 2-5 and Figure 2-6.
The manual bypass switches in Figure 1-1 allow one ALS diversity Group (i.e., ALS-A or ALS-B) to be bypassed and removed from service without tripping the channel.
The manual trip switch may be used to initiate a partial channel trip independently of the ALS logic.

.1.5.4 Isolation Devices The isolation devices shown in Figure 1-3, Figure 1-8, Figure 1-13, and Figure 1-18 are safety-related components powered from the Class II 24 Vdc I/O power supplies provided by PG&E. The isolation devices are separate and independent from both the Tricon and the ALS. All isolation devices are 4-20 mA DC input and 4-20 mA DC output. Input and output range information is provided in the I/O List [Appendix 3.1]. The qualified isolation devices perform the required isolation function when powered from non-safety-related I/O power. That is, credible faults (short circuit, open circuit, application of fault potential) on the Class II terminals will not adversely affect the Class I circuit.
Process Protection System Revision: 7 Interface Requirements Specification Page 9 of 55 1.5.5 ALS Signal Conditioning 1.5.5.1 The ALS shall provide signal conditioning and isolation for the Reactor Coolant System (RCS) non-safety-related flow analog output signals with capability to normalize the scaling periodically.
1.5.5.2 The ALS shall provide signal conditioning for the RCS narrow range Resistance Temperature Detector (RTD) safety-related signals to the Overpower Delta Temperature (OPDT) and Overtemperature Delta T (OTDT) reactor trip functions, and for the RCS Wide Range Temperature and Pressurizer Vapor Space Temperature RTD signals.
1.5.5.3 The ALS shall convert the RTD signals from resistance to temperature. The ALS shall provide capability to update the resistance to temperature conversion coefficients periodically. Analog temperature signal input and output range information is provided in the I/O List [Appendix 3.1]
1.5.5.4 Temperatures shall be transmitted from the ALS to the Tricon via 4-20 mA analog signals scaled per Appendix 3.1.
1.5.5.5 All temperatures shall be transmitted from the ALS to the Gateway computer via RS-422 signals scaled for the full input range per Appendix 3.1.
1.5.5.6 The ALS.shall provide down-scale open RTD protection. If the ALS detects an open or failed RTD, it shall output an analog signal below the Tricon signal failure threshold, which is -5% of span = 3.20 mA per the FRS [6]. If the actual temperature is below the low scale value provided in Appendix 3.1, the ALS shall output the low scale value, or 0% of span = 4.00 mA. This allows the Tricon to provide RTD failure alarming and ensures that the Tricon does not indicate RTD failure when the temperature is below low scale but still functioning correctly, a condition that exists during plant shutdown. In the latter case, the actual temperature shall be available from the ALS via the.
Gateway computer.
1.5.6 Maintenance Workstation Separate and independent Maintenance Workstation computers [Section 2.7] shownin Figure 1-22 are provided for the Tricon and ALS subsystems, respectively, for each Protection Set to allow PPS information processing and display. The two MWS computers in each Protection Set share common HMI peripheral devices such as the keyboard, video display, mouse (KVM), and touchscreen interface through a KVM switch
[Section 2.3.7].
The Tricon will be isolated from its dedicated Maintenance Workstation computer by the qualified safety-related Triconex Communications Module (TCM). Fiber optic cable electrically isolates the Tricon from external non-safety-related devices.
The ALS broadcasts data to its dedicated Maintenance Workstation computer via the isolated one-way TxB2 RS-422 data links. TAB communications between the ALS and the MWS take place via RS-485 data link. The TAB is physically disconnected from the MWS when the TAB is not in use. The TAB is connected and enabled only when maintenance is being performed on the ALS. It is disconnected at all other times. The TAB is enabled for short periods only when ALS maintenance is being performed, and maintenance will be performed under administrative controls by qualified individuals.
This arrangement satisfies NRC DI&C ISG-04, Staff Position 10 of Section 1, Interdivisional Communications [1.4.3.4].
A Maintenance Workstation computer may access data only within its own protection set subsystem (i.e., Tricon or ALS). Communication with other protection sets or between subsystems within a Protection Set is not possible.
Process Protection System Revision: 7 Interface Requirements Specification Page 10 of 55 1.5.7 Plant Process Computer Gateway and Other Non-Safety-Related Communications Interfaces The safety-related Tricon and ALS are connected to the non-safety-related PPC and workstation via the Gateway computer shown in Figure 1-22. The Gateway computer will be installed by PG&E in the Process Control System (PCS) replacement project. The ALS Core Logic Board (CLB) provides isolation for the TxB1 and TxB2 one-way EIA-422 communication links to the PPC Gateway and the Maintenance Workstation, respectively. The ALS transmits data to the non-safety-related Gateway computer, which is common to all four protection sets, and to the Maintenance Workstation using serial, unidirectional, one-way communications channels that do not require any handshaking.
The Tricon will be isolated from the Gateway computer by a data isolation device such as the port aggregator network tap shown in Figure 1-22, which permits two-way communications between the Maintenance Workstation belonging to a specific protection set and the Tricon in that protection set, yet allows only one-way communication to the PPC Gateway Computer. The port aggregator tap will be provided by PG&E.
For system health displays, the PPS will share a HMI unit in the Control Room on CC4 that will also be installed by the Process Control System (PCS) replacement project.
1.5.8 Response Time The reactor trip response time is the time interval from when the monitored parameter exceeds its trip setpoint at the channel sensor, until loss of control rod stationary gripper coil voltage. The ESF response time is the time interval from when the monitored parameter exceeds its trip setpoint until the ESF equipment is capable of performing its safety function. The PPS is allocated a maximum response time of 409 ms [1.4.4.8].
The ALS performs signal conditioning for the narrow range RTD's that support the Overtemperature AT (OTDT) and Overpower AT (OPDT) reactor trips, and the Tricon performs setpoint calculation and comparison and trip output. Therefore, the PPS time response allocation is shared between the ALS and Tricon portions of the PPS for these functions.
The preliminary worst case (deterministic) OTDT and OPDT PPS response time allocations are as follows:
ALS:
175 ms for RTD processing Tricon:
200 ms Contingency:
34 ms Total PPS Allocation:
409 ms The vendor shall provide means of verifying the actual response time if the system does not support deterministic methods of calculating worst case response time characteristics.
1.5.9 Accuracy The FRS specifies existing Eagle 21 accuracy requirements with the intent to maintain currently licensed Channel Statistical Allowance (CSA) margins such that no setpoint changes are required. Accuracy allocation between the ALS and Tricon for the RCS temperature parameters will be determined during the detailed design.

Process Protection System Revision: 7 Interface Requirements Specification Page 36 of 55 2
Interface Requirements This section specifies the requirements imposed on the systems, subsystems, configuration items, or other system components to achieve required interfaces among these entities.
2.1 Process Interface Requirements Appendix 3.1 describes process inputs and outputs for the PPS replacement project.
The I/O list contains the following information for each protection set. As noted below, some I/O list information is outside the scope of this interface specification.
2.1.1 I/O Power Supplies The Triconex qualification requires that separate power supplies be used for analog and digital i/o.
- 1. All Tricon discrete inputs and outputs will be powered in accordance with the requirements provided in the I/O list.
- 2.
The Containment Pressure Bypass switch inputs to the ALS will be dry contacts wetted by 48 Vdc supplied by PG&E.
- 3.
The Pressurizer pressure loops are shared among the ALS, Tricon, and the control system, via qualified isolator modules, and will be powered by the Tricon ETP as shown in Figure 2-3.
- 4. Where the analog input signal source is a process transmitter, bounding loop resistances per the I/O list are as follows:
- a.
Max resistance < 750 ohms
- b.
Min resistance > 200 ohms
- 5. All 4-20 mA analog signals are powered from power supplies located within the PPS cabinets. The 0-10 VDC analog signals from the Nuclear Instrumentation System (NIS) are powered by the NIS.
- 6.
PG&E will provide power supplies which will accommodate the above bounding loop resistance values. Analog input loop power supply voltage should not exceed 40 Vdc, and may be as low as 24 Vdc based on the following considerations and assumptions:
- a.
Rosemount 1154 and 1154 Series H
- 1) Max qualified power supply voltage: 45 Vdc
- 2)
Max Design loop resistance at 45 Vdc input: 1575 ohms
- 3)
Min Design loop resistance at 45 Vdc input: 500 ohms
- 4)
Max Design loop resistance at 24 Vdc input: Approx. 700 Ohms
- 5)
Min Design loop resistance at 24 Vdc input: 0 Ohms
- b.
Rosemount 1153 Series B&D Output Code P
- 1) Max qualified power supply voltage: 40 Vdc
- 2) Max Design loop resistance at 40 Vdc input: 1325 ohms
- 3)
Min Design loop resistance at 40 Vdc input: 500 ohms
- 4) Max Design loop resistance at 24 Vdc input: Approx. 600 Ohms
- 5)
Min Design loop resistance at 24 Vdc input: 0 Ohms
Process Protection System Revision: 7 Interface Requirements Specification Page 37 of 55
- c. Rosemount 1153 Series B&D Output Code R
- 1) Max qualified power supply voltage: 45 Vdc
- 2)
Max Design loop resistance at 45 Vdc input: 1575 ohms
- 3)
Min Design loop resistance at 45 Vdc input: 500 Ohms
- 4) Max Design Loop Resistance at 24 Vdc input: Approx. 700 ohms
- 5)
Min Design Loop Resistance at 24 Vdc input: 0 ohms
- d.
Barton 763 max power supply voltage: 50 Vdc
- e. Barton 763 Max loop resistance at 40 Vdc input: Approx. 1250 ohms
- f.
Barton 763 Min loop resistance at 40 Vdc input: Approx. 190 ohms
- g. Triconex 3805N Analog Output module OVP: 42.5 Vdc
- h. ALS input resistance is 220 ohms [Figure 2-4] when both "A" and "B" 302 boards are in the circuit.
- i.
Triconex 9792-61 ON Reg. Guide 1.180 FTP Max 48 Vdc (Approx. input resistance: (250 + 1/(1/250 + 1/3300)) - 482 ohms)
- j.
Input and output loop resistances as shown in Appendix 3.1 based on Triconex resistance above and:
Isolator input 4-20 mA into 20 ohms (estimated)
Westinghouse VX-252 indicator: 5 ohms (including estimated wire resistance)
ERFDS: 50 ohms RVLIS: 250 ohms
- k.
ALS 4-20 mA analog outputs are powered by the ALS. Therefore, temperature inputs to the Tricon will not use the Positive Temperature Coefficient (PTC) thermistor for loop overcurrent protection and the input resistance for Tricon temperature inputs is 250 ohms.
- 7.
Tricon Analog Output Power Supply
- a. Analog outputs in the safety-related Triconex Main Chassis will be powered by redundant 24 Vdc power supplies furnished by PG&E.
- b.
Analog outputs in the non-safety related Triconex Remote RXM chassis will be powered by redundant 24 Vdc power supplies furnished by PG&E and mounted in the rack housing the RRXM chassis.
- c. The Tricon analog output power supply shall not be shared with any discrete input or output signals.
2.1.2 Analog Inputs Figure 2-2, Figure 2-3, and Figure 2-4 illustrate typical PPS analog input signal wiring
[1.4.5.6, 1.4.5.7]:
- 1. PT-455 signal shared among Tricon (DTTA functions), ALS-A, ALS-B and an isolation device
- 2.
LT-459 signal shared among Tricon, Control Board indicators and an isolation device
- 3.
PT-505 signal shared among the Tricon, and an isolation device
- 4.
RCS Temperature signals are conditioned by ALS-A and ALS-B, respectively before they are input to the Tricon. Example wiring for these signals is shown in Figure 2-3.
- 5.
Tricon Al cards 3721 (where used) and 3721N shall be configured for 14-bit resolution, unipolar. These cards are used for all 4-20 mA analog inputs to the PPS
Process Protection System Revision: 7 Interface Requirements Specification Page 38 of 55
- 6.
Tricon Al cards 3703E (where used) and 3703EN shall be selected for 0-10 Vdc input, fail downscale. These cards are used for Nuclear Instrumentation (NI) inputs to the PPS.
- 7.
Signals from redundant field devices shall be processed on separate input boards.
2.1.3 Discrete Inputs Signals from redundant field devices shall be processed on separate input boards.
2.1.4 Discrete Outputs Figure 2-5 and Figure 2-6 illustrate typical ALS discrete output signal wiring that implements the diversity architecture [Figure 1-1] using a Line Sense Module (LSM) to provide a hardwired OR configuration between Diversity Groups ALS-A and ALS-B and to enable the ALS to perform continuous error checks for detecting the following conditions:
Failure to Trip on Demand Trip without Demand Failure to Bypass Illegal Bypass The LSM is illustrated in Figure 2-1. Configuration of the LSM for use in an Energize to Trip (ETT) or Deenergize to Trip (DTT) circuit is done through field wiring terminations on the LSM and does not require any modification of any electrical properties of the LSM itself. Thus, a single LSM can be used in an ETT or DTT circuit without the need to electrically configure the module for the trip circuit type before use. This allows a single part number to be used to provide spares for both ETT and DI7 circuit configurations.
Refer to the ALS Design Specification [1.4.5.6] for additional information regarding the LSM and field wiring interface.

Revision: 7 Interface Requirements Specification Page 47 of 55 Tricon and ALS subsystems in each Protection Set to allow independent processing and display of information from both Triconex and ALS portions of the PPS. The HMI application in the Tricon MWS computers shall interface (2-way) with the Tricon. The TS1 131 PPS application contains function blocks that allow WRITE-access to a limited set of parameters programmed into the application software with the Tricon keyswitch in the RUN position. Without these function blocks programmed into the application program application program parameters cannot be modified with the keyswitch in the RUN position. The Tricon protection set is considered inoperable when the keyswitch is not in RUN position.
The HMI application in the ALS MWS computers shall interface (1-way) with the ALS via the isolated TxB2 RS-422 data link. The two MWS computers in each Protection Set share peripheral devices through a KVM switch. Refer to Section 2.3.7 for details.
2.7.2 Auxiliary Service Unit Application Software Software application shall be provided by Vendor CS Innovations to run on the ALS Maintenance Workstation Computers. The ASU application utilizes a two-way RS-485 communication link to communicate with the Test ALS Bus (TAB) that is physically disconnected from the MWS computer when it is not in use. The activation of the TAB via connecting the TAB data link to the MWS computer does not interfere with the ability of the ALS safety channels to perform their respective safety functions and the ALS is still operable during activation of the TAB. Therefore, individual instrument loops may be placed is bypass for maintenance and the rest of the ALS safety channel is still operable with respect to its safety function.
To detect the TAB connection, the ALS-1 02 DI #2 needs to be connected to ALS-1 02
'lnput.Rtn as shown in Figure 2-7 [Reference 1.4.5.8, Figure 4-2].
2.8 Alarm Interface Requirements The PPS shall provide the following alarm output signals from each Protection Set for connection to the Main Annunciator System (MAS) in the DCPP Main Control Room (MCR). Separate input signals shall be provided for these alarms from each Protection Set per Section 3.2.1.5 of the FRS [1.4.4.2].
2.8.1 PPS Failure (Deenergize to Alarm with Reflash capability)
The conditions listed in FRS Section 3.2.1.5.1 shall provide signals to initiate the PPS Failure alarm in the Main Control Room.
2.8.2 PPS Trouble (Deenergize to Alarm with Reflash capability)
The following platform-specific inputs to the Main Control Room PPS Trouble Alarm shall be provided in addition to those listed in FRS Section 3.2.1.5.2. Other alarms not listed here or in the FRS may be provided to meet platform diagnostic requirements.

5 OOS; Instrument has been removed from service.
2.9.6 On-Line Maintenance and Test Interface 2.9.6.1 The PPS shall provide capability for maintenance bypass during power operation; that is, the PPS shall permit removal of the capability of an individual channel or channels to perform its protective action due to a requirement for replacement, repair, test, or calibration [GDC 21].
2.9.6.2 The maintenance and test functions shall be accomplished without lifting electrical leads or installing temporary jumpers.
2.9.6.3 The channel or channels subject to the maintenance bypass may remain in the bypassed condition within administrative time limits in accordance with DCPP technical specifications established to meet the single failure criterion per IEEE-603-1991 Sections 5.1 and 6.3.1.
2.9.6.4 Capability to initiate protective action (i.e., to initiate partial trip or actuation) from a channel that has been removed from service for maintenance shall be provided per IEEE 603-1991 Section 6.3.2 and DCPP Technical Specifications.
2.9.6.5 Capability of the PPS to accomplish its safety function shall be retained during maintenance bypass per IEEE-603-1991 [1.4.2.2] Section 6.7.
2.9.6.6 Tricon PPS Subsystem Specific Requirements
- 1. External trip switches will be provided on PPS partial trip and actuation outputs that de-energize to trip. The switches may be used for SSPS input relay testing or to trip or actuate the channel manually if needed. External trip switches are not required for energize to trip outputs.

Process Protection System Revision: 7 Interface Requirements Specification Page 53 of 55
- 2.
On-line testing shall be controlled by the safety-related Tricon processor enabled via a permissive from an external safety-related hardwired Out of Service (OOS) switch.
- 3.
When the OOS switch is activated, the safety-related function processor shall allow the associated instrument channel to be taken out of service while maintaining the remainder of the Protection Set operable. Features to limit inadvertently placing a channel OOS shall include, but not be limited to:
- a. Approved PG&E procedures are required to perform testing operations.
- b. Operation of the hardware OOS switch alone shall not place the channel out of service.
- c.
More than one specific action shall be required at the Maintenance Workstation to perform the maintenance functions. In order to perform any test operation from the maintenance workstation, the user must:
(1) Activate the OOS switch for the specific loop to be tested (2) Log in as a maintenance user on the maintenance workstation (3) Open the maintenance screen for the specific loop being tested (a) On the maintenance screen, request the desired test mode (b) On the maintenance screen, confirm the requested test mode (Loop
.is placed OOS only after the requested mode is confirmed)
(c) If it is desired to change the test mode, repeat steps 3.(a) and 3.(b) while the channel is OOS; selecting a different test mode alone shall not cause or require returning the channel to service.
(4) The channel shall return to service:
(a) When the OOS switch is returned to its normal position; or (b) When so commanded from the MWS
- d.
Feedback is provided to the user on the maintenance workstation that the hardware OOS switch for the loop to be tested has been activated.
- e. Continuous indication is provided in the control room that a loop is OOS.
- f.
If the safety-related hardware out of service switch is not activated, non-safety-related actions or failures cannot adversely affect the safety-related function.
- g.
An instrument loop is not permitted to be bypassed if external trip switch is in the trip position. The user may test in trip in this condition following request and confirmation as described above.
- 4. Maintenance modes allowable under 3.c.(3) above shall include:
- a. Test in Bypass: The channel trip output is maintained in the untripped condition while in this mode; that is, Test in Bypass mode shall override the output of the channel trip comparator to prevent generation of a partial trip from the channel being tested.
- b. Test in Trip: The channel trip output is maintained in the tripped condition while in this mode; that is, Test in Trip mode shall override the output of the channel trip comparator to initiate partial trip or actuation from the channel being tested.
- c.
Parameter Update: Capability to update parameters such as trip setpoints or tunable parameters.
(1) The parameter values to be updated are limited by the software application to pre-determined ranges.
Process Protection System Revision: 7 Interface Requirements Specification Page 54 of 55 (2)
The Maintenance Workstation software application shall request operator confirmation that the parameter update process is complete prior to saving the new tuning constant.
2.9.6.7 ALS PPS Subsystem Specific Requirements
- 1. ALS bypass and test functions are accomplished through ALS Service Unit (ASU) software implemented in the MWS as discussed in Section 2.7.2.
- 2.
Placing a specific channel in maintenance bypass shall not affect the safety function of other channels in the same ALS chassis that are not subject to the same maintenance bypass.
- 3.
Placing an individual channel in maintenance bypass in one ALS chassis (e.g.,
Chassis "A") shall not affect the safety function of any channels in the diverse ALS chassis (e.g., Chassis "B) in the same protection set.
- 4.
Multiple channels may be placed in maintenance bypass concurrently within an ALS chassis. However, placing multiple channels in maintenance bypass shall require individual bypass actions for each channel. Multiple channels shall not be placed in maintenance bypass by a single action.
- 5.
The Test ALS Bus (TAB) must be physically connected to the MWS as shown in Figure 2-7 to allow two-way communications on the TAB between the ALS chassis and the MWS.
- 6. The ALS-A and ALS-B chassis partial trip outputs are hardwire OR'd to the SSPS input relays through an external LSM to allow either ALS chassis to initiate a trip or actuation. Refer to Figure 2-5 and Figure 2-6 for LSM usage.
- 7. The LSM shall not allow an ALS chassis to prevent the diverse ALS chassis from initiating a required trip or actuation.
- 8.
External bypass switches are provided for the individual ALS-A and ALS-B partial trip outputs to allow removal of an ALS circuit board in without initiating a false trip or actuation.
