5–98 469 MOTOR MANAGEMENT RELAY – INSTRUCTION MANUALCHAPTER 5: SETTINGS5.14 S13 469 Testing5.14.1 Simulation ModePATH: SETTINGS ZV S13 469 TESTING Z SIMULATION MODEThe 469 may be placed in several simulation modes. This simulation may be useful forseveral purposes.• First, it may be used to understand the operation of the 469 for learning or trainingpurposes.• Second, simulation may be used during startup to verify that control circuitryoperates 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 inthe 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 forthe measured values in the 469 when the simulation mode is “Simulate Pre-Fault”. Thevalues entered as Fault Values will be substituted for the measured values in the 469 whenthe simulation mode is “Simulate Fault”. If the simulation mode: Pre-Fault to Fault isselected, the Pre-Fault values will be substituted for the period of time specified by thedelay, 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 469measures phase current or control power is cycled, simulation mode will automaticallyrevert 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 mightbe desirable to short the 469 Test input (C3 and C4) to prevent all of this data from beingcorrupted 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.SIMULATION [SIMULATION MODE:OffRange: Off, Simulate Pre-Fault,Simulate Fault, Pre-Fault toFaultMESSAGE PRE-FAULT TOFAULTRange: 0 to 300 s in steps of 1
