1. Ensure that Resistor R91 is in the module circuit by l l installing Jumper JU2 and removing Jumper JU1 (see l l Figure 3). l l
2. The Multiplier-Divider may be calibrated at the racks or in the shop.
3. To calibrate the module at the racks, once installed per.

l Step V.D., remove the module from its slot and connect the extender cable between the slot connector and the module.

a. If the module is to be calibrated while connected to the rest of the loop, apply the input by lifting the field input wiring on TB B, terminals 1 and 2 and connecting the ramp generator to terminals 1

(+) and 2 (-). The ramp generator will be used as a current source, therefore it must be used in the external mode of operation. Read the module input voltage with a DVM at the module input I and ground test points. ,

b. If the module is to be calibrated while not connected to the rest of the loop, apply the input by lifting the leads on terminals 1 and 2 of terminal strip 3D and connecting a voltage source to terminals 1 (+) and 2 (-). Read the module j input voltage with e DVM at the module input 1 and ground tast points.

3. Using the ramp generator, ramp a simulated signal from 2.000 to 1.000 VDC at the rate of 1/2 V/ min. Record on Data Sheet 5 the As Found trip voltage for the flow comparator using the DVM connected at FC-RH605A Input 1 test points.
4. Readjust the ramp generator to ramp from 1.000 to 2.000 VDC at 1/2 V/ min. Record on Data Sheet 5 the As Found Reset voltage for the flow comparator using the DVM connected at FC-RH605A Input 1 test points.
5. If the As Found values are satisfactory, complete the Final column of Data Sheet 5 and proceed to the next step. If the As Found yalues are unsatisfactory, calibrate the flow comparator as follows.
a. Adjust the ramp generator for an input of 1.391 Vdc (1250 gpm.)
b. Adjust comparator FC-RH605A SETPOINT vernier dial (CW to increase the trip point, CCW to decrease the trip point) until the required trip is obtained, as indicated by the output fuse indicating light de-energizing.

NOTE: INITIAL ADJUSTMENT OF THE SETPOINT DIAL SHOULD BE IN THE CCW DIRECTION UNTIL THE OUTPUT FUSE INDICATING LIGHT ENERGIZES, THEN IN THE CW DIRECTION UNTIL THE LIGHT JUST DE-ENERGIZES.

c. Adjust the ramp generator for an input of 1.456 Vdc (1350 gpm),
d. Adjust the comparator DEADBAND potentiometer (CW to increase the reset point, CCW to decrease the reset point) until the required reset point is obtained, as indicated by the output fuse indicating light energizing.

NOTE: THE COMPARATOR SETPOINT AND DEADBAND TEND TO INTERACT.

IT MAY BE NECESSARY TO REPEAT STEPS V.I.5.a THROUGH d SEVERAL TIMES TO OBTAIN SATISFACTORY RESULTS.

c. Repeat Steps V.I.3 and 4, completing the Final column of Data Sheet 5.
f. If the data is still unsatisfactory, refer to the Manufacturer's Instruction Bulletin, for corrective action. After corrective action has been I

completed, repeat Steps V.I.3 and 4, completing the

( Final column of Data Sheet 5.
