Actuator Output for Contactor
If, during ascertainment of control parameters (manual optimization or self-tuning), a
cycle time
results which is significantly shorter than advisable
for the service life of the contactor,
cycle time
can be increased to the limit of system controllability by configuring the actuating outputs for contactor
control (
rELA
=
YES
). If the bit is set before self-tuning is started, cycle time is set to the highest possible value by the self-tuning function.
Water Cooling
In order to account for the disproportionately powerful cooling effect which prevails when water is evaporated, the cooling control variable can be read
out in a modified fashion by configuring the switching output for water cooling (
Outx
=
H2O
).
Configuration of the Controller with Continuous Output
Switching back and forth between current output and voltage output is automatic based upon load impedance.
Continuous output = heating or cooling
Cont
=
HEAt
or
CooL
The manipulated variable is read out within a range of 0 to 100% depending upon controller type.
Continuous output = controlled variable or setpoint
Cont
=
Proc
or
SP
The momentary controlled variable of the currently valid setpoint is read out.
The read-out is scaled with the
rnL
and
rnH
parameters.
