relay. Normal (pre-fault), fault and post-fault conditions can be simulated to exercise a
variety of relay features. There are three sets of input parameters used during simulation,
each provides a particular state of the system as follows.
All Simulation setpoints revert to default values at power-up.
Path:
Setpoints > Testing > Simulation > Setup
• Simulation State
• Force Relays
• Force LEDs
SIMULATION STATE
Range: Disabled, Prefault State, Fault State, Postfault State
Default: Disabled
Program the Simulation State to "Disabled" if actual system inputs are to be monitored.
If programmed to any other value, the relay is in test mode and actual system
parameters are not monitored, including Current, Voltage, and Contact Inputs. The
system parameters simulated by the relay are those in the following section that
correspond to the programmed value of this setpoint. For example, if programmed to
"Fault", then the system parameters are set to those defined by the Fault setpoint values.
While in test mode, Contact Input states are automatically forced to the values set in
Setpoints\Testing\Contact Inputs.
When the Fault State is set as the Simulation State and a Trip occurs, the Simulation
State automatically transitions to the Postfault State.
PRE-FAULT TO FAULT TRIGGER
Range: Off, any FlexLogic Operand
Default: Off
FORCE RELAYS
Range: Disabled, Enabled
Default: Disabled
When in test mode, and Force Relays is "Enabled", relay states can be forced from the
Setpoints\Testing\Output Relays menu, this overrides the normal operation of the output
contacts. When in test mode, and Force Relays is "Disabled", the relay states maintain
their normal operation. Forcing of output relay states is not performed when the
Simulation State is "Disabled".
FORCE LEDS
Range: Disabled, Enabled
Default: Disabled
When in test mode, and Force LEDs is "Enabled", LED states and colors can be forced
from the Setpoints\Testing\Test LEDs menu, this will override the normal operation of the
LEDs. When in test mode, and Test LEDs is "Disabled", the LED states and colors will
maintain their normal operation. Forcing of LEDs is not performed when the Simulation
State is "Disabled".
