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 settings 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.
