WARNING!
Sensor run-in periods
This can result in dangerous incor‐
rect metering
– Correct measuring and
metering is only possible if the
sensor is working perfectly
– Refer to the operating instruc‐
tions for the sensor
– Calibrate the sensor after com‐
missioning
Following mechanical and electrical instal‐
lation, integrate the controller into the
measuring point.
7.1

Initial commissioning

The controller is in STOP mode when the
controller is first switched on.
Setting the auto-ranging profile
1. Select the inductive conductivity
sensor used.
2. Enter the actual sensor cable
length.
ð Subsequently enter the control
setting and the setting for the
different parameters dependent
on the process to be measured.
3. Set the auto-ranging profile when
connecting external sensors,
[INPUT > SENSOR > MANUAL] .
7.2 Setting the control during
commissioning
NOTICE!
Reset to factory settings
When switching over the metering
direction, all actuators in the con‐
troller are reset to the factory set‐
tings for the selected metering
direction.
For safety reasons, all the actua‐
tors are deactivated. The basic
load is reset to 0 %. All parameters
relating to the actuator, are reset to
the factory setting.
Reset all the parameters that relate
to the actuator.
The controller only controls
Only one position or one negative control
variable can be calculated. The direction
of the control variable is set in the
'PUMP' menu. There is no dead zone. In
this sense, the control cannot be
'deactivated' (except with 'STOP' or
'PAUSE' ).
The value of the P-proportion of the con‐
trol (Xp) is specified for the controller in
the unit of the corresponding measured
variable.
With pure P-control and a difference
between the set and actual values, which
corresponds to the Xp value, the calcu‐
lated control variable is +100% (at the
'raise' setting) and -100% (at the 'lower'
setting).
