Relays of alarms, from high to low Failure, R5, R4, R3, R2, R1.
- Failure: Non-configurable failure relay
- R1 to R5: Configurable alarm relays
- Corresponding LED indicator: Lit when relay is under voltage.
Configuration of Alarm Thresholds
The alarm thresholds for relays R1 to R5 can only be configured using the COM 43
software. The silkscreen image displays relays off line.
Relays R1 to R5 can be configured in either positive or negative security mode. COM 43
programming in:
- Normal mode: Operation of the relay as per the normal alarm management (the relay is
released only if the event exceeds the duration of the time delay).
- Buzzer mode: The same as in normal operation, with, in addition, the possibility of
releasing the buzzer relay even if the event is still present. The time delays are:
. Duration of maintenance: Minimum time of activation, adjustable from 0 to 900
seconds.
. Automatic release: Time adjustable between 15 and 900 seconds, beyond which the
buzzer relay is automatically released.
. Reactivation: Time adjustable between 15 and 900 seconds, beyond which the buzzer
relay is reactivated.
Alarm Relay Controls
- Logic equations of up to 4 levels of parentheses by the logic operators OR, AND, NOR,
NAND. The result of the equation controls the relay.
- Polling Operations (x over y): There must be at least “x” events over the total of “y” to
activate the relay. Optionally, the user may define whether a failure is considered an
event in the same category as an alarm.
