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.
