Simulation
Parameters P-76 through P-78 can be used to simulate relay operation in the program
mode. Pump relays will be held OFF during simulation, however their corresponding
LED’s will respond. Remote totalizer and flow sampler relay operation do not apply to
simulation. Refer to Parameter Description.
If the relay status can affect plant operation or personnel safety,
it is advisable to override the relay functions or disconnect the relay
wiring during calibration or simulation
Keep power disconnected at main breaker
when MultiRanger Plus cover is opened.
Relay Function Vs Mode of Operation
It should be noted that some relay functions can not be used in certain modes
of operation. The following table shows the valid functions for the five modes
of operation.
