Circulation monitoring
The circulation monitoring must be checked
regularly. The input used must be configured
as “Controller Stop.” The dosing of chemicals
must switch off if the circulation is deactivated
or the circulation output is too low, e.g. dosing
switches off with digital input 2 used as “Con-
troller Stop.”
3.5.8 Digital inputs
There are five integrated digital inputs on the
CPU-board of the electronics module. They
are provided for connection of voltage-free
contacts (< 100 Ohm) and are supplied inter-
nally with 24 V.
The functions of the digital inputs can be con-
figured for the specific customer application in
the "Input/Output” menu. Digital input 1 is
used for sample water monitoring and cannot
be changed.
Digital input DI 1
With the help of the voltage-free contact of
the flow rate monitor on the flow fitting, the
controllers can be influenced:
•
Before expiry of the sample water moni-
toring delay time (0 to max. 10 min.):
The chlorine dosing pump and the dosing
pump for pH correction continue dosing
at the same rate.
The positioner remains unaffected.

After expiry of the sample water monito-
ring delay time:
The chlorine dosing pump and the dosing
pump for pH correction are switched off.
The positioner moves to 0 %.

Digital input DI 2 to DI 5
Various functions can be assigned to the digi-
tal inputs. With the help of a voltage-free ena-
bling contact, e.g. circulation off, the
controllers can be stopped immediately:
•
The chlorine dosing pump and the dosing
pump for pH correction are switched off.
The positioner moves to 0 %.

•
Empty signal contact of the chemical
tank(s).
The chlorine dosing pump and the dosing
pump for pH correction are switched off.

Cl
2
/pH tank monitoring
If the Cl
2
/pH tank monitoring is activated,
DI 3 to DI 5 are used for connection of the
chlorine and pH suction lances. At mini-
mum fill level, a message is generated for
each tank, and if one of the two tanks is
empty, chlorine and pH dosing switches
off.
•
Standby function
When the Standby function is activated,
all controllers are switched off and dosing
is deactivated. The alarms are disabled.
Measured value displays are hidden. This
function is used to switch off the measu-
ring and control system when circulation
and the sample water are switched off
simultaneously.
DANGER
Risk of injury or death!
A circulation monitoring device must be
installed in the unit and connected to the
electronics module. Chemical dosing must
switch off if the circulation is switched off or
the circulation rate is too low. To ensure safe
operation and prevent injury, it is essential
to install circulation monitoring
WARNING
Do not apply voltages at the digital input ter-
minals!
NOTICE
Controller switch-off is only effective in
“Safety MAN. mode“.

Controller switch-off is only effective in
“Safety MAN. mode“.
NOTICE
When the contact closes, restart of the cont-
roller may be delayed due to the dosing
delay time. In as-delivered status, the digital
inputs are disabled. To activate the function,
connect an external contact and configure
the digital input in the menu. The digital
inputs can also be assigned as alarms.
