Description of function

3.1. Design
IND 220 is suitable for mounting all ring-shaped metal parts (e.g. rolling bearings, gear wheels, flanges and pulleys) that are mounted on shafts with press tension. As with an  induction cooker, a magnetic field is generated in the medium frequency range, which induces a voltage in the inner ring of the workpiece. The eddy currents thus generated  heat the workpiece and expand it so that it can be mounted on the shaft without applying force. All components of the heater remain cold.
All workpieces to be heated must be made of magnetic metals. This property can be easily checked by means of the temperature probe supplied.

3.2. Scope of delivery
The heating device is delivered with power cable, temperature probe, protective gloves and a bag.
3.3. Nameplate and designation
Each heating device is marked by means of the CE symbol and a nameplate. The nameplate contains information on the manufacturer and the serial number.

Troubleshooting

| NOTICE
---|---
Damaged or flawed electrical connections or unlicensed hot components lead to heavy injuries or even death.
• The procedures described below mayonly be performed by properly trained and qualified professionals using all mandatory PPE‘s.

6.1. The device does not switch on
Check for voltage in the electrical system. If it is verified that there is voltage and the heater still does not work, check that the glass fuse on the electronic board is blown. To  do this, it is necessary to open the drawer below the heater‘s power connector.

6.2. The device does not heat up
If it is found that there is voltage in the socket and the device still does not heat up, the temperature probe may be damaged.
Replace the temperature probe.

6.3. Error messages on the display

temperature and start again when the tower has cooled down.
•E001| Temperature probe does not record an increase of 1 °C every 60 seconds| Check the temperature, material and dimensions of the workpiece (—>chap. 3.4 Technical data). If these are not within the parameters, the workpiece will not reach the programmed temperature and will stabilise at a temperature below.
Check the position of the temperature probe. It must be placed on the inner ring of the workpiece (chap. 5.4 Position temperature
probe).
