The set point is the value to be
maintained by the control. This
value is to be re-established by
the control in the event of any
deviation (up or down).

Setting may or may not be
required depending on control
deviation (up or down deviation,
see chpt. 5.5.2).
R237
Selection of pulse
length or pulse
frequency
len
=
pulse length
freq = pulse frequency
Pulse length e.g. for solenoid valve,
pulse frequency e.g. for solenoid-
operated metering pump (see
chpt. 5.5.2).
R238
Enter pulse interval
10.0 s
0.5 ... 999.9 s
This field only appears if pulse
length is selected in R237. When
pulse frequency is selected,
R238 is skipped and input
continues in R239.
