Description of function

Design

IND 160 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.
The working principle of the IND 160 heater can be compared to that of a transformer. The voltage and electric current, which circulates in the turns of the induction coil, induces a low voltage and therefor a high intensity of electric current in 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.

Commissioning & operation

Control panel

The control panel consists of a regulator and two buttons that control the heating device. Three control LEDs inform about the current status of the unit.

1. Time/temperature regulator
2. Button mode
3. Button ON/OFF
4. LED device is activated
5. LED error display

Electrical connection

Before starting to work, inform yourself in detail about the heating device using this user manual; and follow the general safety instructions (→chap. 2.6) in particular. The heater‘s mains power supply must be properly grounded and the socket must be in accordance with the cable plug.

Place yoke with the workpiece.

• Based on the table in →chap. 3.5 select the correct placement yoke for your workpiece and then put through the inner ring of the workpiece. Observe the specifications for material and dimensions.
• Place the yoke with the adhesive strip facing downwards and with the workpiece centred on the two support yokes.

Position temperature probe

• Clean the temperature probe and remove fillings.
• Position the temperature probe on the inner ring of the workpiece.
• The use of heat-conducting material is recommended but not mandatory.

| NOTICE
---|---
Incorrect positioning of the temperature probe can damage the workpiece during the heating process.

•       Position the temperature probe only on the inner ring of the workpiece.

Contact with the heated workpiece or the support and placement yokes can damage the cable on the temperature probe.

•       Make sure that the cable does not touch these parts of the device

during the entire heating process.

Heating process in temperature mode

The heating process can be carried out in time or temperature mode.
In temperature mode, you can program the temperature to which the workpiece is to be heated. After switching on the unit, the mode from the last use is preselected.

Initial state 1): The LED of the „Mode“ button is not lit
Temperature mode is already activated, no further action is necessary.
OR Initial state 2): LED of the „Mode“ button is lit
Press the “Mode“ button.
The LED of the “Mode“ button goes out, the temperature mode is activated.

The heating temperature is set via the control panel.
Select the required temperature (white scale) using the regulator.

Excessively high temperatures can damage the workpiece or the heating device.

• Observe the temperature specifications of the heating device (→chap.

3.4 Technical data ).

• Press the “ON/OFF“ button to start the heating process.
• The LED on the „ON/OFF“ button lights up.
• The workpiece is heated until the programmed temperature is reached.
• The heating process stops automatically as soon as the programmed temperature is reached.
• The LED of the „ON/OFF“ button flashes for 2 seconds and then goes out.
• Remove the heated workpiece with protective gloves and mount it.
• Press the “ON/OFF“ button to interrupt the heating process.

Heating process in time mode

The heating process can be carried out in time or temperature mode.
In time mode you can programme the time period within which the workpiece is to be heated. This mode is used when the exact heating time is known from previous heating processes. After switching on the unit, the mode from the last use is preselected.

Initial state 1): LED of the „Mode“ button is lit
Time mode is already activated, no further action necessary.
OR initial state 2): LED of the „Mode“ button is not lit
Press the “Mode“ button.
The LED of the “Mode“ button goes out, time mode is activated.

The heating time is set via the control panel.

Select the required time (red scale) using the regulator.

Do not choose a time period that exceeds the recommended temperatures.

• Press the “ON/OFF“ button to start the heating process.
• The LED on the „ON/OFF“ button lights up.
• The workpiece is heated until the programmed time is up.
• The heating process stops automatically as soon as the programmed time has elapsed.
• The LED of the „ON/OFF“ button flashes for 2 seconds and then goes out.
• Remove the heated workpiece with protective gloves and mount it.
• Press the “ON/OFF“ button to interrupt the heating process.

Demagnetization takes place automatically at the end of each heating cycle.

Troubleshooting

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.

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.

Error messages on the display

FAILED SENSOR

| ****

Temperature probe faulty

| Check the condition of the temperature probe. The cable must not be ripped, broken or crushed over its entire length. If the cable or temperature probe are damaged, replace them. If there is no damage and the error is still displayed, contact the manufacturer.

OVER TEMPE- RATURE

| ****

Device overheats

| If the coil reaches a temperature of more than 80 ºC, the appliance is deactivated. It is not possible to switch on the unit until the core temperature has dropped. Once the temperature has dropped, the LED goes out and the unit is ready for use again.
