7.3 Workpiece installation
•
After pressing 'STOP', place the sensor on the side of the pole.
By pressing 'STOP', the workpiece is demagnetised automatically.
•
Wear heat-resistant gloves. Place the yoke with the workpiece on a clean surface. If the heater
has a swivel arm, open it up to the safety positioning cam and slide the workpiece off. Install the
workpiece without delay and prevent it from cooling down.
7.4 Error message
•
If no temperature increase of at least 1ºC is measured within the time pre-set by the manufacturer,
the induction heater automatically switches off. The display blinks and shows 4 hyphens (----). An
alternating, clear beep is sounded. Press STOP to switch off the beep and check whether:
•
the sensor has been placed on the workpiece
•
the sensor plug has been inserted in the socket
(Make sure that the – and + of the plug correspond to that of the socket.)
•
the wiring of the sensor has not been damaged
•
the surface area of the sensor is clean
•
the workpiece is within the specifications for the heater as listed in chapter 9
If the sensor is faulty, as a contingency measure, the workpiece can be heated with the time
mode. The temperature needs to be measured with an external thermometer.
7.5 Switching between Celsius and Fahrenheit
•
The induction heater operates in the temperature units °C or °F.
Follow the procedure below to switch between these two units:
•
Press and hold the temperature key for 10 seconds. When pressing, a short beep is sounded.
•
After 10 seconds, another short beep is sounded and the display changes from one
temperature unit to the other.
•
The heater can now be operated using the newly set temperature unit.
