General description
The EC3020 controller is used for the fully automatic monitoring and control of
single or duplex cylinders for exchange cylinder systems, whereby the filter
cylinders have to be regularly exchanged.
The basic controller parameters can be changed at any time; the programmed
values are not lost in the event of a power failure.
The controller operates according to 7 steps, indicated as "Service Filter 1",
“Standby Filter 1”, "Service Filter 2", “Standby Filter 2”, “No Service”, “No Service
1+2” and “No Service 2+1”.
The controller checks the conductivity of the water and if this exceeds a settable
limit value, performs the following actions:
- In case of single filter systems, switches to “No Service”.
The Service valve is closed and, once the cylinder is exchanged, the system must
be switched on by hand using the external key.
- In case of duplex systems, switches to the other filter cylinder.
If the engaged filter cylinder, within a programmed period, also produces water with
too high conductivity, the system is switched off.
After replacing the filter cylinders, these can be switched on by hand, using the key
on the outside of the controller.
In single filter systems, the service valves of the cylinder must be connected to
“SV1”.
