Central instrumentation & control
There are floating relay contacts to enable the osmosis plant to be monitored by a control console.
Additional floating contacts can be created using external relays.
If there is an IF plug-in card installed, the OUT1 and OUT2 relay outputs can be assigned the following
signals as signal or alarm outputs during the programming sequence:
1 MIN conductivity 1
2 MAX conductivity 1
3 Osmosis plant - stop
4 Tank - empty
5 Tank - full
6 Exceeded pressure
7 Low-water pressure
8 Concentrate flow
9 Motor circuit-breaker
10 Power failure
11 Maintenance required
12 "PRODUCTION" phase
13 "STANDBY" phase
A number of signals may be assigned to each relay.
WARNING! If the floating relay contacts are also needed for switching valves, lamps or horns, for ex-
ample, you will have to use extra external relays to serve as floating contacts.
The following floating contacts can be created using extra external relays:
PU = Pump (High-pressure pump running)
IV
= Input valve (System in operation)
CV = Concentrate flush valve ("RINSE" phase)
