Operating procedures

5.3. Connecting the temperature sensors
To avoid error message and safety shutdown (see page 40),
attach sensors “SF” and “INT” before switching the instrument
ON.
 Attach the working sensor to socket labeled “INT” and the
safety sensor to socket labeled “SF”.
Sensor calibration:
When the controller is first placed into operation or whenever a
sensor is replaced, a working sensor calibration must be
carried out (ATC - see page 39).
Caution:
Place both sensors into the bath medium and securely fix the sensors.
5.4. Controlling an intermittent cooling water supply
The control output (35) is intended for the attachment of a
solenoid valve (230 V or 115 V - max. 1.25 A) which can be
used to control the flow of a liquid coolant. The flow of a
coolant is indicated by the illumination of a green indication
light on the control panel of LC6.
The solenoid valve is designed to be attached to the coolant
supply line.
Order-No. Description
8 980 703-3 Solenoid valve (230 V)
8 980 703-2 Solenoid valve (115 V)
Caution:
Securely attach all tubing to prevent slipping.
