WIRING
WARNING: if 2 wire Pt100 is used, connect compensation lead to
measuring lead: (SXT48S: 10-11)
Use correct compensation cables for T/C sensors.
Connect T/C cable directly to the device connectors.

PROGRAMMING HEAT SET
ON-OFF is active when “H.Hys” is other then 0
ON-OFF CONTROL
PID PARAMETERS
- P, PI, PD, PID is active when “H.Hys” is set to 0 (only for heating; h-C is set to ”HEAt”)
- PbC: Proportional band in ºC.
- Ct: Control period for PID control. Prefer 4-10 sec.
- Ti: Integral time; Set in minutes. Determines how fast controller reacts to compensate 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 part 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 oscilla
te or overshoot.7
CLEANING
Do not use any solvents (alcohol, thinners, benzine, acid, etc.) or corrosive substances to clean the device.
Use only a dry and clean non-abrasive cloth.
Before cleaning, disconnect the power supply and mains connections.
