Time delays
Custom alarms are activated once the pick-up threshold has been reached and the configured pick-up time delay has elapsed. Likewise, custom alarms are
deactivated after the drop-out threshold is reached and the drop-out time delay has elapsed. Both pick-up and drop-out time delays are independently
configurable, from a minimum 1 second to maximum 3000 seconds.
The time delays are provided as cumulative counters based on the time elapsed, which increments as the measured value reaches or exceeds the
threshold value, and decrements if the measured value drops below the threshold value. Activation and deactivation of the respective custom alarm requires
the time-delay counter to reach the configured time delay.
Pick-up time delay
: For the activation of a custom alarm, the pick-up time delay counter:
-
Increases by 1 per second when the pick-up threshold value is met or exceeded.
-
Decreases by 1 per second if the pick-up threshold value is not met and the cumulative elapsed time is not reached.
-
Resets to 0 when the cumulative time delay is reached and custom alarm is activated.
Drop-out time delay
: For the deactivation of a custom alarm, the drop-out time delay counter:
-
Increases by 1 per second when the drop-out threshold value is met or exceeded.
-
Decreases by 1 per second if the drop-out threshold value is not met and the cumulative elapsed time is not reached.
-
Resets to 0 when the cumulative time delay is reached and custom alarm is activated.
If an alarm is reconfigured using the TPED or TPCM whilst a custom alarm time delay counter has begun, the counters are reset to 0.
Example: A custom alarm is set to a positive activation pick-up threshold of 280 V for an overvoltage measurement of V1N. The pick-up time delay is set to
4 seconds. The drop-out threshold value is set at 250 V and the drop-out time delay at 2 seconds.
