TIME DELAY: 15 s
The 469 may be placed in several simulation modes. This simulation may be useful
for several purposes.
• First, it may be used to understand the operation of the 469 for learning or
training purposes.
• Second, simulation may be used during startup to verify that control circuitry
operates as it should in the event of a trip, alarm, or block start.
• In addition, simulation may be used to verify that setpoints had been set
properly in the event of fault conditions.
Simulation mode may be entered only if the motor is stopped and there are no trips,
alarms, or block starts active. The values entered as Pre-Fault Values will be
substituted for the measured values in the 469 when the simulation mode is
"Simulate Pre-Fault". The values entered as Fault Values will be substituted for the
measured values in the 469 when the simulation mode is "Simulate Fault". If the
simulation mode: Pre-Fault to Fault is selected, the Pre-Fault values will be
substituted for the period of time specified by the delay, followed by the Fault
values. If a trip occurs, simulation mode will revert to Off. Selecting "Off" for the
simulation mode will place the 469 back in service. If the 469 measures phase
current or control power is cycled, simulation mode will automatically revert to Off.
If the 469 is to be used for training, it might be desirable to allow all learned
parameters, statistical information, and event recording to update when operating
in simulation mode. If however, the 469 has been installed and will remain installed
on a specific motor, it might be desirable to short the 469 Test input (C3 and C4) to
prevent all of this data from being corrupted or updated. In any case, when in
simulation mode, the 469 In Service LED (indicator) will flash, indicating that the
469 is not in protection mode.
