RELY – Alarm Relay Operation
The RELY function configures the operation of the Modline 5 Alarm relay for Normally Open or
Normally Closed operation. The Sensor internal relay contacts are available on the Black and
Black/White twisted wire pair of the Sensor cable. The Alarm Relay contacts are used to report a Sensor
alarm condition.
The sensor self-tests its case temperature, detector assembly temperature, output current flow, etc. The
Check function checks internal circuit and detector operation. The optional Dirty Window Detector
measures the Sensor’s window condition. One or more out of limit conditions sensed by these tests
triggers an Alarm.
Set the relay operation to correspond to proper and safe use of the contacts in your overall measurement
system. Select N C. for closed relay operation with Sensor not in Alarm condition (open in alarm state).
Select N.O. for closed relay operation with Sensor in Alarm condition (open when not in alarm
condition).
Contacts are open for both N.O. and N.C. operation when the Sensor is not powered, and, for the 3 to 5
seconds after power is applied during the initiate period.
Normally Closed N.C, operation is considered fail-safe operation.
