4. Selecting the programmable functions
The system features FULL and EMPTY inputs for the purposes of reservoir
control. The functions of inputs IN1, IN2 and, if there is a plug-in IF card in-
stalled, IN3 are programmable.
You have a choice of 5 options. Each function may only be utilised once.
INPUT 1 function
Select your choice of input
function for input IN1. The
section on “Input functions“
contains a description of
the inputs.
Press INFO to see the meaning of the abbreviation in plain text.
ST = Stop EX = External switch
EP = Exceeded pressure LP = Low-water pressure
CO = Concentrate
INPUT 2 function
Select your choice of input
function for input IN2, as
described in 4.1.
INPUT 3 function
Select your choice of input
function for input IN3, as
described in 4.1 (only if you
have an IF plug-in card
installed).
General note:
If there is a thermal motor circuit-breaker installed in the front panel in 230 V models, the corre-
sponding alarm contact is connected directly onto the PCB. An input is not required for that
switch.
Activating the input functions
Choose activation options
for the FU and EM func-
tions, as well as for the
inputs selected in pro-
gramming steps 4.1-4.3.
"|" Function is activated when the contact is closed (NO-contact)
"-" Function is activated when the contact is open (NC-contact)
Press INFO to see the meaning of the abbreviation in plain text.
FU = Tank full input CO = Concentrate
EM = Tank empty input EX = External switch
ST = Stop LP = Low-water pressure
EP = Exceeded pressure
General note:
In deciding between an NO-contact or an NC-contact, assume that a break in the power supply
to the contact or non-closure of the contact are more likely faults. This will not result in damage to
the system. Example: over-pressure switch. A faulty switch may result in damage to the module.
Therefore, use a switch with an NC contact.
