Refers to output K2. For explanation see Setpoint 1.
Only with activated setpoint changeover
If setpoint changeover is configured for one of the logic inputs,
then setpoint pair 1 is active if the logic input is inactive, i.e. the
controller uses the setpoints 1 and 2 (SPr1 and SPr2) for
operation.
If the logic input is active, then setpoint pair 2 is active, i.e. the
controller uses the setpoints 3 and 4 (SPr3 and SPr4) for
operation.
Active setpoints are identified by an "r" in the parameter name
(SPr1 and SPr2 as well as SP3 and SP4 if setpoint pair 1 is
active).
Setpoint limiting for controller setpoints.
This parameter is used to define the upper limit setting for the
controller setpoints SPr1/2/3/4.
Setpoint limiting for controller setpoints.
This parameter is used to define the lower limit setting for the
controller setpoints SPr1/2/3/4.
This value is taken from the operating instructions for the
attached instrument.
Example for a JUMO 202630 (transmitter for free chlorine ->
transmission range = 0 — 2.0 mg/l):
SiL = 0.00
The behavior of an alarm contact.
Steady contact:
The alarm output remains active until the switching condition
(the cause) of the alarm is no longer present.
The LED blinks for the output that was defined as the alarm
output.
Pulse contact:
The alarm output remains active for approx. 1 second, even if
the switching condition (cause) of the alarm remains present for
a longer time.
The LED (for the output that was defined as the alarm output)
blinks until the switching condition (the cause) of the alarm is no
longer present.
The process value goes above or below the setpoint. The
switching condition is also dependent on the settings "Break
contact/make contact" and "MIN/MAX contact".
