TESTING CHAPTER 4: SETPOINTS
NOTE
NOTE:
All Simulation setpoints revert to default values at power-up.
Setup Path: Setpoints > Testing > Simulation > Setup
• Simulation State
• Pre-Fault to Fault Trigger
•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.
NOTE
NOTE:
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, On, 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”.
