8.2 Heating in time mode
•
Position the workpiece and sensor (according to chapters 6 & 7.) Only use the sensor if you
want to check the temperature before the countdown has completed.
•
Switch on the heater and press '' . Enter the desired time by pressing '▲' or '▼'; by pressing
'' , you can select increments of either 1 minute or 1 second.
•
Press 'START' . The heating starts, you will hear a slight humming sound. Press '' during
heating to display the current temperature for 3 seconds. The countdown then continues.
•
During heating, the pre-set time counts down to 00:00. When 00:00 is reached, the induction
heater switches off. The workpiece is then demagnetised automatically and a loud, continuous
beep sounds. Press 'STOP' to switch off the beep.
8.3 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.
8.4 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 10.
If the sensor is faulty, as a contingency measure, the workpiece can be heated with the time
mode. In this case, the temperature must be measured with an external thermometer.
8.5 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.
