on page 10
WARNING!
Sensor run in periods
This can result in hazardous incor‐
rect metering
– Correct measuring and dosing
is only possible if the sensor is
working perfectly
– Please read the operating
manual for the sensor
– The sensor must be calibrated
after commissioning
Following completion of mechanical and
electrical assembly, the controller should
be integrated into the measuring point.
6.1

Initial commissioning

When the controller is first switched on,
the controller is in STOP state.
Subsequently the control settings and set‐
ting of the various, process-dependent
parameters is undertaken.
6.2 Setting the controller 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 actuators
are deactivated. The base load is
reset to 0 %. All parameters
relating to the actuator, are reset to
the factory setting.
Consequently all parameters
relating to the actuator, must be
reset.
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, 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 corresponding measured variable unit.
For pure P-control and a separation
between the set and actual values, which
corresponds to the Xp value, the calcu‐
lated control variable is +100% (with set‐
'raise' ) and -100% (with setting
ting
'lower' ).
