Each relay; Low, Mid, High and Fault; can be individually configured to latch when it is activated. Setting a relay to ‘latch’ will cause it to remain activated after the condition that activated the relay has cleared. This causes the user to acknowledge the activation in order to clear any alarms.
Delay:
Delay can also be applied to the activation (ON) or deactivation (OFF) of the individual relays. The delay can be up to 255 seconds for each setting. If a delay is set to the relay activation (ON DELAY) the alarm or fault associated with that relay will not be triggered until after the alarm condition has remained for the duration of the delay. Similarly, if a delay is applied to the deactivation (OFF DELAY) the alarm will remain engaged for the number of seconds beyond when the alarm condition has cleared. Use caution when applying ON DELAY to the activation of alarm relays as an unsafe atmosphere may be present for up to 255 seconds prior to any alarms being activated.
Setting Relay Latching and Delay Conditions – set individually for each alarm/fault relay
Move the cursor to the desired alarm (LOW, MID, HIGH or FAULT) and select ENTER.
