Note!
Detailed information on the types of control is
provided on the CD-ROM D+.
For acid/base dosing in each
case:
Actuator (only for pulse
length)
Activation and subsequent entry
• Relay:
n.c., rel. x
• Period
001.0 ... 999.9 s
• Min. on time
000.4 ... 100.0 s
Factory setting
Relay: n.c.
Period: 010.0 s
Min. on time: 000.4 s
Select the settings for the actuator.
Relay:
Select the relay; you can choose from
the relays that you assigned to the controller in
"Set up 1 - Relays".
Period:
Period length T in seconds
Min. on time:
Minimum switch-on time;
shorter pulses are not passed on to the relay and
thus protect the actuator.
For acid/base dosing in each
case:
Actuator (only for pulse
frequency)
Activation and subsequent entry
• Relay:
n.c., rel. x
• Max. frequency
060 ... 120 min
-1
Factory setting
Relay: n.c.
Max. frequency: 120 min
-1
Select the settings for the actuator.
Relay:
Select the relay; you can choose from
the relays that you assigned to the controller in
"Set up 1 - Relays".
Max. pulse frequency:
Enter the maximum
pulse frequency; pulses with a higher frequency
are not passed on to the relay.

Select the characteristic type.
Linear characteristic
Corresponds to a
constant control gain.
Segmented characteristic
Corresponds to a
range-dependent control gain.
