1. Press Calibrate/Parameters/Relays.
2. For built-in relays select either soft key A, Relay1, or soft key B, Relay2.
For a relay unit select key 3, Relay unit and then select the relay to be programmed (in -WR relays
A and B, in PR-7080 relays A, B, C, D).
3. Select the relay function
0 Not defined
1 Processor OK The relay is ON if the processor is running
2 Normal operation The relay is ON if the diagnostic message is
Normal operation
.
3 No malfunction The relay is ON if the diagnostic message is
Normal operation
or Low conc/no sample.
4 Low limit Low alarm relay, relay is ON if value below limit.
First choose an alarm source from the following list:
− CONC %
− Standard RI (25
◦
C)
− TEMP ◦
C
− TEMP ◦
F
− TEST
− Sensor temperature
− Sensor humidity
Then enter a alarm limit. The default value of the limit is zero.
5 High limit High alarm relay, relay is ON if value above limit.
First choose an alarm source from the following list:
− CONC %
− Standard RI (25
◦
C)
− TEMP ◦
C
− TEMP ◦
F
− TEST
− Sensor temperature
− Sensor humidity
Then enter a alarm limit. The default value of the limit is zero.
6 Preconditioning A preconditioning relay. Relay unit only.
7 Wash A wash relay. Relay unit only.
8 In divert control Not used with PR-03.
Important: An alarm relay configuration always requires the following information: high or low limit,
alarm source and alarm limit. The configuration is not complete until all the information is entered to
the IT-R.
Note: If needed, you can adjust alarm delay by pressing the key 4, Alarm delay in the Relays display
(Calibrate / Parameters / Relays). The same delay applis to all relays and is used to prevent
oversensitive alarms. The source value has to be out of limits during the whole delay time, given in seconds,
to activate the relay. The default value for the alarm delay is ten seconds.
