CHAPTER 3 CONTROlS AND FACIlITIES
q. Time Delay Alarms
The operation in response to alarm events of certain relays may
be modified by applying a delay function to the relays. Time delay
functions are available to delay the activation of a relay for a short
period after an alarm event occurs and/or to maintain relay activation
for a period after the alarm event has cleared. The time delay facilities
are available for:
i. Relays 1 to 4 if the Quad Relay Interface Card is fitted.
ii. Relays 1 to 8 if the Relay Interface Assembly is fitted.
The time delay function is useful to prevent spurious alarms and to
ensure appropriate minimum operating times for external electrical
apparatus connected to the relay.
