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 con-
ditions.
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.
