Remote monitoring control
Typical installation diagram.
Remote monitoring control.
In order to permit remote monitoring of the water softening unit, a number of volt free relay contacts are
available. Additional contacts can be obtained by wiring in of external relays.
The relay outputs
AN = Warning
and
MF = Alarm
can be used for any of the following signals:
1. Capacity
exceeded.
2.
Power supply failure.
3.
Chemical tank low.
4. Await
regeneration.
5.
Minimum time between regeneration’s.
6. Regeneration
pre-contact.
The following relay outputs are also available.
AD = Additional program routine (signal programmable during regeneration.)
RE = Regeneration (regeneration taking place.)
FL = Water flow (water meter pulse)
The following contacts could be repeated using an external relay.
SV1 = Unit 1 outlet valve. (Unit 1 in service)
SV2 = Unit 2 outlet valve. (Unit 2 in service)
Using two external relays and the output
RE = regeneration
it is possible to obtain signals as shown
below:
Unit 1 in regeneration Unit 2 in regeneration
IMPORTANT
The external relay contacts should not be used to provide both volt free signals for
monitoring and powered signals for control, use additional relays.
