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 val-
ues entered as Pre-Fault Values will be substituted for the measured values in the 469 when the simulation mode is "Simu-
late 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 sub-
stituted 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 con-
trol 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.
