Warning:
!
Use shielded and twisted signal cables and connect shield to ground on device side. Use correct compensation cables
for T/C sensors. Connect T/C cable directly to the device connectors. Keep all signal cables away from contactors,
devices/cables emitting electrical noise, power cables.
Keep device away from contactors, devices/cables emitting electrical noise, power cables. Take precautions agains
environmental conditions like humidity, vibration, pollution and high/low temperature during installation.
Use fuse (slow 250mA 250VAC) on mains/supply input of the device. Use appropriate cables for mains connections.
Apply safety regulations during installation.
Displays “FAiL” message in case of sensor failure, measurement out of range or hardware fails to
measure input signal.

Auto Tune:
Before starting “Auto-tune”, adjust H.SET.
“Auto tune” does not start in“cooling” mode.
Process value may exceed H.Set during
auto-tune.
After auto-tuning, control form automatically
switches to PID mode.
Auto-tuning is stopped (interrupted) ant time
by pressing any key. In this case, the
parameters before auto-tuning is valid.
Auto-tuning may not always determine the
best values for your process.

(1) When sensor type is changed, Up.L, Lo.L, H.Set or A.Set may be set to a new value automatically, if any of
then violates measuring scale of the selected sensor.
(2) ON-OFF control is only option for Cooling function.
(3) If sensor type is selected as Pt.0.
Minimum delay before OUT becomes ON
after it becomes OFF.
Determines the duty cycle of OUT output
when “Fail” message is displayed. If 0, OUT is always OFF.
If 100, OUT is always ON, when device “fails”. Period is Ct.

PID Parameters:
P, PI, PD, PID is active when “H.Hys” iss et 0 (only for heating; h-C is set to “HEAt”).
PbC: Proportional band in C.
Ct: Control period for PID control. Prefer 4-10 sec.
Ti: Integral time; Set in minutes. Determines how fast controller reacts to compansate the offset between SET point and
the process value. If set to 0, integral part is OFF. If set too low, process value may oscillate.
Td: Derivative time; Set in minutes. If set to 0, derivative parf is OFF. Determines how sensitive the controller is to
changes of the offset between SET point and the process value. If set too high, process value may oscillate of overshoot.
