q. Time Delay Alarms
The operation in response to alarm events of certain relays may
bemodied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tted.
 ii. Relays1to8iftheRelayInterfaceAssemblyistted.
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.
