Relay selection
(for three-point step controller)
+Relay : Open the valve further (= increase dosing)
–Relay : Close the valve further (= reduce dosing)
Selection: n.c. (= not connected). After this, the relays which have
been released in the Contacts menu are always offered as the
default.
!
Note!
If you cannot select a relay here, use the "Contacts" menu to make
relays available for the controller function.
Motor run time : The time the motor drive requires to move the
valve from completely closed to completely open. The CPM153
requires this to be able to calculate the required pick-up time of
the relay for any required position change.
Xdg : Maximum differential gap between valve and position feed-
back. If the difference is greater than the edited value, it will be
compensated by position changes.
!
Note!
The CPM153 expects feedback from the actuator drive about the
current valve position via a current or resistance input.

max. pulse frequency : Input of the maximum pulse frequency.

Current output 2
(for current output)
Selection of the current range, which should be output at the
current output.
y=0%
0/4 mA
20 mA Current output
Assign the current value which corresponds to 100 % dosing
medium provision.
Type:
With selection "two-sided":
Dosing via:
1 output
2 outputs
Control:
(This is only possible if you selected the continuous controller
under current output 2.)
1 output : for control using the current output in the "split range"
method. Control logics are required which can control two
valves/pumps over one current input.
2 outputs : If the valves are controlled with two relays.
