These would be represented by two such vertical lines, both below the normal load current. Be sure to set the alarm
level
above
the trip level. Both trips and alarms are held off by the start delay. Each has its own run or pickup delay.
Use the start delay to block tripping until the load stabilizes after a start. Use run delays to avoid nuisance alarms or
trips for load transients.
To configure this function for operation under an alarm condition, the User must assign the functions pickup ( for
example 50J[1].Pickup) to an output relay, under >>Device Parm / Relay Outs<< that the User has identified as the
Alarm relay output. Likewise, to illuminate an LED under a functions alarm condition, LED 2 must be assigned the
functions pickup. Several elements are configure as such at the factory for convenience.
