Description of signal inputs
Note!
Connect the signal inputs "MP", "HL", "LL", "HP", "LP", "STOP", "CO" and "PROG" only to volt-free contacts!
MP Motor protection
When using pumps which are equipped with a motor protection circuit breaker with a volt-free message contact, it is
possible to connect this switch to input "MP". The controller will then monitor and, according to the programming,
evaluate pump faults.

The connections "HL" and "LL" can be used for controlling the production:
a) For plants with a storage tank:
As soon as the lower level "Tank empty" (connection "LL") has been
reached, the contact transmitter closes and the plant is switched on
("Production"). It is only switched off again if the upper level "Tank
full" (connection "HL") has been reached and this contact
transmitter opens.
It is also possible to use only an upper level transmitter (float switch)
or a remote control switch (Production/Standby) instead of two level
transmitters. In this case, the connection "LL" has to be connected
via a bridge with "
┴
". The
A

@
key ("Production / Standby")
will then be without function.
Note!
If using automatic concentrate displacement via permeate (flush), observe that, depending on the pressure ratios, soft
water can still run into the storage tank until the end of the flushing duration. Due to this, the upper level transmitter has
to be arranged in a way that an tank overflow is avoided. For safety reasons, the tank should in any case have an tank
overflow to the drain. It is possible to install an level transmitter above the
A
Full level
A
in order to monitor the tank
overflow.
Connect this switch to the programmable signal input "PROG". The plant automatically switches off if the "Tank overflow
level" has been reached.
Note!
When operating the osmosis plant without a level transmitter (manual operation), a bridge has to be connected across
the connection
A

A
. A bridging of the connection "LL" is not allowed.
b) For plants with one pressure switch or remote control switch:
Connect a bridge to the connection "LL" and the pressure switch to the connection "HL". The pressure switch must have
a normally closed contact.
