1.0 GENERAL INFORMATION 1.0 GENERAL INFORMATION
1.1 INTRODUCTION
The NMP-1000 Is a microprocessor based wide-range linear power module which provides percent reactor power Indication and bi-stable trip circuits. The module Is packaged in a metal enclosure suitable for mounting In a reactor control console. The NMP-1000 module processes current of 1E-11 to 1 E-3 Amperes from any detector producing current within input range, e.g. ion chamber or fission chamber. A compensating voltage power supply is provided for use with compensated ion chambers. The input current is converted into Oto 10V In 9 one-decade' ranges. The appropriate decade is selected either automatically by software (auto mode) or by the user (manual mode) via the touch screen display or a remote input The NMP-1000 has two modes of operation, local or remote. In local mode, the module accepts commands via the front panel touch screen or a remote display*. In remote mode, the module accepts commands via the Ethernet port or the analog remote Interface connectors on the rear panel. A detailed list of the remote interface pinouts Is given in section 6 of this manual.
Three (3) bi-stable trips are used to alarm on low high voltage to the detector and two Independently adjustable levels of reactor power. Three relays are provided with two sets of normally open and normally closed contacts for customer use. The relays are held energized in a fail-safe condition until an alarm de-energizes the coil.
The NMP-1000 has test modes to allow the user to test the proper performance of the electrometer and to ensure the functionality of all trip circuits. Test modes Include HV, calibrate high, calibrate low, and manual current. The HV and calibrate high test modes cause the bi-stable trips to alarm; current low gives fixed power indication in the highest range; and manual test lets the user vary the current over all ranges with a front panel potentiometer. Test modes can be enabled via the touch screen or a remote interface.
A photo of the NMP-1000 is provided in Figure 1-1.
- The remote display is available as an option. It is Identical to the front panel display and connects to the RS-232 port on the rear panel.

~lgure 2-3 Multi-range Linear Module NMP-1000, Interior View 2.2.1 :Motherboard (T3400113-001)
Refer to schematic T3400111 for circuit details.
- The NMP. motherboard serves as the backplane for all)~MP PWA's (daughter cards). It provides the power for all d~ughter cards, HV power supply and compensation power supply. It contains somf!3 circuitry for monitoring voltage levels and range indicators. Connections between all daughter cards and peripheral devices such as the*
display or remote connectors are made via the motherboard.
The motherboa~ provides a number of connectors where all daughter cards plug in. Connectors are keyed and of different pin count, and in combination with card guides, only allow one type of daughter ca~ to be installed }n a partieular slot Additional connectors accept the cable connections to the rear panel remote connectors, as well as connections to the dlsplay and front panel Pt/I/A Incoming signal llnes for control slgnals originating* at the remote
2.0 DESCRIPTION
connector on the rear panel are protected by a resistor/diode network. Outgoing signals are generally Isolated via relays, opto-lsolators, or another method.
Additional circuitry ties in with the trip/alarm PWA If either the watch dog timer or operate signals are lost, the NMP will go out of operate and set all trips. While the NMP is in auto mode and also not in the highest range (e.g.
1E-3), the percent power signal is pulled low, essentially preventing a power trip from occurring. If the NMP is taken out of auto mode, or the highest range has been reached, the percent power signal Is released and the trip circuits are enabled. Jumper settings let the user configure which current range is the highest range. The software receives indication that the highest range has been reached via a feedback circuit.
Table 2-2 Jumpers (Motherboard - Highest Range)
Highest Range JP1 I JP2 Notes 1E-3 X 1-2 Factory Default 1E-4 1-2 2-3 Install FC~73 (see appendix) 1E-5 2-3 2-3 Install FC~74 (see appendix)
In the factory default condition, the Test Currents (see sectlon 4.3.4) are in the appropriate range; Hl Test Current can be adjusted from about 95% to 125% power, and Lo Test Current ls hard-wired to about 18% power. If JP1 and JP2 must be repositioned to accommodate a different high range, the Test Currents wlll not change unless the corresponding FCO, as listed in Table 2-2, is installed.
All relays that Indicate the active power range to the user are located on the motherboard. The relays are controlled by the microprocessor by the same signal that also sets the range on the analog amplifier.
There are two Jumpers on the motherboard that affect the start-up mode of the display. One jumper lets the user set the program mode. When the program mode ls enabled, the display will accept programming to the flash. This setting Is used only when it is necessary to reload the Display OS or when the code that was complled has locked up the display. The other jumper will start up the display in calibration mode. In normal use, the calibration mode can be accessed via the About menu of the NMP. Changing this jumper should only be necessary if the display brightness and contrast are very far out of calibration and calling the callbration routine from the screen is impossible.

Normal Use 2-3 2-3 Program/Calibrate 1-2 1-2 All analog +/-15 Vdc power for the NMP is generated by two linear power supplies on the motherboard.
Transformers step down the 117 Vac nominal input voltage which then gets rectified by bridge rectifiers and filtered. Linear regulators convert the primary DC voltages into +/-15 Vdc. The transformers are sized to provide sufficient voltage to the linear regulators with 90% AC line input. +15 Vdc is also routed to the rear panel connector that is accessible to the customer for external auxiliary circuits. This external supply voltage is fused with a 1OOmA, self-resetting fuse.
A 25W switching power supply on the motherboard generates +24 Vdc to provide power to the HV power supply and digital circuitry. The Input is fused with a 3A, slow acting glass fuse. +24 Vdc is also routed to the rear panel connector that is accessible to the customer for external auxiliary circuits. This external supply is fused with a 250mA, self-;esetting fuse.
2.2.2 Analog Amplifier Board (T3400133-001)
Refer to schematic T3400131 for circuit details.
The analog amplifier board measures the incoming current signal from the detector and converts it into a linear analog voltage In nine one-decade ranges. For every decade of current, the analog board returns a O to +10 Vdc signal. Because the NMP is designed to measure power up to 120% of nominal reactor power, an output voltage of +10 Vdc represents 1.2 x nominal current In every decade (e.g. 120nA or 1.2mA). In general, the NMP-1000 and detector should be setup such that 1mA equals 100% reactor power. This is accomplished by performing the bench calibration in section 4.3, reinstalling the instrument, operating the reactor to determine actual power levels (via other instrumentation), and then physically repositioning the detector so the NMP indicated power equals actual power.
At the heart of the analog amplifier board is a high input impedance operational amplifier. For every decade of current, a relay switches in the appropriate feedback resistor to generate the expected output signal. The 1E-11 is the default range and always active. Other ranges are switched into the circuit in parallel as determined by the microprocessor. Every range has an adjustment potentiometer that allows for calibration of the circuit The high impedance ampllfier is followed by a buffer amplifier with an adjustable gain potentiometer.

2.0 DESCRIPTION
The microprocessor contains two Universal Asynchronous Receiver/Transmitter (UARTs} that are used for communication with the display and the remote display/maintenance port on the rear panel via RS-232. The remote display/maintenance port is isolated with Its own power supply and digital isolator. The nominal isolation voltage is >1,500 Vrms.
A watch dog timer (WOT} monitors the activity of the microprocessor. If the WOT receives no input from the microprocessor for more than 1.6 seconds, the WOT sends an alann and takes the module out of operate. When a WOT alarm occurs, the heartbeat LED will stop blinking, the loss of communications will cause all trips to set, and the console WOT Alarm will occur. A WOT alarm is latching in the Instrument and can only be reset by cycling power (or, if the Instrument cover Is off and the Instrument is in Test Mode, by pressing S2 on the Digital Interface Board). The heartbeat LED indicates the activity of the microprocessor and will blink about once per second as long as all software tasks are executing properly. A WOT alarm is expected to be an extremely rare event.

If dipswitch #5 is in the LOGIC O position (and dip switches #1, #2 and #3 are not all LOGIC 0),
then the microprocessor will support only a single connection on the TCP/IP socket.
NOTE: If dipswitches #1, #2 and #3 are all in the LOGIC O position ("OOOn),
then no Ethernet communications is possible.

If dipswitch #8 is in the LOGIC 1 position, then the system will accept test commands over the Ethernet. This dipswitch is only used during initial factory and site testing and is placed "OFF" at the conclusion of testing. When dipswitch #8 is enabled, the instrument responds to a remote 'Test' command. When dipswitch #8 is disabled, a remote 'Test' command will result in an error signal.
2.2.4 Trip/Alarm Board (13301133-001)
Refer to schematic T3301131 for circuit details.
The trip/alarm board contains six identical circuits to generate all trip and alarm indications. Every circuit is jumper configurable for a rising or falling trip. A comparator monitors an incoming signal voltage and compares it to a reference voltage. The reference voltage is user adjustable via a potentiometer. When the circuit is configured for a rising trip, the comparator will switch states when the amplitude of the incoming signal exceeds the reference signal. A falling trip works the opposite way; when the incoming signal amplitude falls below the reference voltage, the comparator will switch states. Once a trip has occurred, the circuit latches in the tripped state. The only way to unlatch the circuit is for the user to apply a reset signal, even if all signal levels return to nominal prior to the reset.
Every trip has a DPDT (Form C} relay that the user can connect to via the remote connectors. The relay is controlled by the output of the comparator and the operate signal. Taking the NMP out of operate mode (such as during a self-test} will immediately activate all trip relays. This is considered the failsafe condition - when all trips are set and latched, but not necessarily indicated by the front panel LEDs or remotely.
The trip logic signal (comparator output} is only activated when the comparator input exceeds its setpoint. Simply taking the NMP out of operate mode will not activate the trip logic signal. The front panel LEDs, opto-isolator T3401000-1UM REVISION: B 2-12
2.0 DESCRIPTION
outputs, and Ethernet indications are driven by the trip logic signal, and so will only indicate a trip when the comparator input exceeds the setpoint.
Because entering any self-test mode causes the loss of the operate signal and therefore activates the trip relay; the user may, in some cases, choose to bypass the operate signal on a trip circuit. To disable this feature, jumper settings have been provided to prevent a given trip when the instrument enters a test mode.
NOTE: this feature does not change operation of the trip in normal operations
- the trip will still activate the relay if the setpoint is exceeded. It simply prevents an automatic trip when entering test mode.
Important: The Operate and WOT signals are logically tied together on the motherboard PWA. Bypassing the operate signal on a trip circuit also bypasses the WDT on the same trip. All trip circuits are independent of each other, so jumper settings and Operate Enable/Bypass for any one trip will not affect any others. The front panel LEDs and Ethernet output are not affected by this jumper.

2.0 DESCRIPTION
As an example, consider the HV trip jumper set to Operate Bypass. If the operator enters any test mode, all trips except the HV trip will go to failsafe mode (meaning, the trips activate). If the operator then initiates the HV trip test; the HV trip will occur, the front panel LED will light, and the Ethernet trip signal will be sent. If the operator returns to normal operations (but does not change the jumper position), the HV trip is still active and will trip if a HV fault occurs. However, if only a WDT occurs, the HV trip will NOT indicate a fault (all other trips not in Operate Bypass will go to failsafe).
2.2.5 Isolation Amplifier Board (13133113-001)
Refer to schematic T3133111 for circuit details.
The isolation amplifier board houses two isolated outputs that can be jumper configured for either voltage or current output. The isolators are commercially available programmable voltage to current converters. The converters provide 1500Vrms galvanic isolation. Adjustment potentiometers allow the isolators to be calibrated for offset and span.
Table 2-12 Analog Outputs Jumper Settings Output Offset Span A R12 R11 B R14 R13 AO to +10 Vdc input will generate a 4 to 20mA or Oto +10 Vdc output that is available to the user via the remote connectors. The minimum compliance voltage for current loop operation is +8 Vdc. Voltage output is achieved by inserting a shunt resistor into the loop. The receiving device should have an input impedance >50k0, otherwise unacceptable measurement errors may occur.

2.2.6 Display The display on the front of the module is a Monochrome LCD Display with white LED backlight. The display has a viewing area of 3.8 inches (diagonal) and a resolution of 320 X 240 (QVGA). The display includes an integrated touch panel and integrated digital backlight & contrast controls. A complete graphical operating system that executes GUI applications built in dynamic HTML is included with the display.
2.2.7 Front Panel Board (T3400123-001)
Refer to schematic T3400121 for circuit details.
The front panel board houses the red LED indicators for all trips, activated by the trip/alarm board. The remote/local switch lets the user control whether the module is in remote or local mode. A green LED indicator is wired in with the switch; it is lit when the module is in remote mode.
A potentiometer lets the user manually control the current in test mode. This potentiometer is accessible with a knob on the front panel. Two recessed potentiometers, accessible via the front panel with an adjustment tool, let the user adjust the compensation power supply voltage on the NMP.

Table 2-15 Potentiometer (High Voltage}
Potentiometer Function R4 High Voltage Adjustment 2.2.9 Compensation Power Supply The compensation power supply produces an output voltage from -8 to -200 Vdc (depending on the part number, see below} with a ripple of less than 10 mVp-p. The +5 Vdc input power is derived from the +15 Vdc analog supply and a linear regulator. The output of the compensation power supply is controlled by a O to +3 Vdc programming voltage that can be adjusted by the user with potentiometers accessible on the front panel of the NMP. The compensation power supply is short circuit protected with two external resistors. As a result, depending on the load, the maximum voltage may not be available to the load, as the protection resistors will drop some voltage. A voltage sense circuit monitors the output and returns Oto +10 Vdc for Oto maximum output voltage. To accommodate a variety of detection systems and user situations, three different compensation power supplies are available:
- Part number T3401000-001 provides a -30 to -200 Vdc compensation power supply.
- Part number T3401000-002 provides a -8 to -50 Vdc compensation power supply.
- Part number T3401000-001 provides a -23 to -150 Vdc compensation power supply.
NOTE: All of the compensating power supplies drop out around 15-20% of their maximum output voltage. This is a result of fundamental design characteristics from the OEM and cannot be changed.

(% Power) DMM-Figure 4-2 Analog Amplifier Board Layout 4.3.2 Power/Current Calibration In general, the NMP-1000 and detector shouJd be setup such that 1mA equals 100% reactor power. This is accomplished by first performing the bench calibration described below, then reinstalling the instrument, operating the reactor to determine actual power levels (via other instrumentation), and physically repositioning the detector so the NMP indicated power equals actual power.
T3401000-1UM REVISION: B 4-4
4.0 MAINTENANCE (CALIBRATION) 4.3.2.1 Setup - Null NOTE: Anytime any circuit boards are removed or installed, instrument power must be OFF to prevent damage to the circuits. Use caution and discharge static electricity to the extent practicable before handling or working with circuits.
- a. Install the extender card for the analog amplifier and install the EMI shield .
- b. Connect a DMM to TP1 (+) and TP6 (-) on the Analog Amplifier PWA.
- c. Set the current source for an output of zero current (O.OOOnA), and wait at least 5 minutes. Adjust potentiometer R1 until the DMM reads 0.00 +/- 0.05 Vdc on TP1 . After every adjustment, wait at least 5 minutes for the voltage to settle. Readjust _until the desired accuracy is reached.
NOTE: When adjusting the offset voltage, pay attention to the com pliance voltage of the current source. If necessary, readjust R1 until the compliance voltage displayed by the current source is a positive value.
Any positive value is fine. A negative value will cause the manual current test to fail (range will not be adjustable down to 10E-11 range with the front panel potentiometer), as it will produce a small current that is additive to the expected current from the manual current source.
When setting R1 for a positive compliance voltage rather than OV offset, a small measurement error will be introduced in the lowest current range. That error is dependent on the amplitude of the compliance voltage and is typically less than 10% at 5pA.
- d. On the MAIN MENU Display, select the Gain button to enter the GAIN MENU Display.
4.3.2.2 E-11
- a. Select the E-11 button on the GAIN MENU Display.
