Page 7: Safety Precautions And Operating Notes
Intended use EDDYTHERM is only intended for use as a heating device in industrial applications. It is designed for the inductive heating of components, such as ball bearings, for shrink fitting. The device and its accessories should only be operated by personnel trained in their use. -
Page 8: Safety Precautions
EDDYTHERM 1x and EDDYTHERM 1-6 have the protection class IP22 (protected against penetration by objects with a diameter greater than 12.5 mm, protection against dripping water). EDDYTHERM 4x has the protection class IP20 (protected against penetration by objects with a diameter greater than 12.5 mm, no protection against water). - Page 9 The equipment may only be operated and serviced by trained personnel.

EDDYTHERM operating manual Starting EDDYTHERM EDDYTHERM 4x cable holder EDDYTHERM 4x is provided with a bracket upon which excess power cable may be hung to avoid damage or the danger of tripping. Setup Simply plug the heater into the power socket. The indicator LED for the “temperature shutoff” operating mode lights up. -
Page 15: Mounting The Workpiece
EDDYTHERM operating manual Mounting the workpiece To achieve the best possible efficiency, always choose the largest possible crossbar. This is the only way to guarantee that the workpiece will be heated rapidly. Slide the workpiece onto the crossbar and then place the crossbar onto the columns with the unpainted side facing down. - Page 16 EDDYTHERM operating manual Multiple identical workpieces Multiple workpieces can be heated together if they are identical, i.e., have the same weight and the same dimensions. Demagnetization of tools Mount the demagnetization bar (optional) as shown in the figure below. Press the demagnetization key and hold the tool in the gap of the demagnetization bar.

Page 17: Eddytherm 4X Swivel Crossbar
Bearing size The powerful EDDYTHERM 4x can heat workpieces or roller bearings weighing in excess of 200 kg in a short period of time (example: bearing 23088, 180 kg/396 lb, heated from 20°C/68°F to 100°C/212°C in approx. 8 minutes). - Page 18 EDDYTHERM operating manual Bearings with brass or bronze cages When bearings with brass or bronze cages are to be heated, care must be taken to ensure that the cage does not heat faster than the inner bearing ring. This could cause the lubrication contained in the bearing pockets to become overheated, which in turn could, in extreme cases, lead to overheating of the rolling elements themselves.

Page 19: Temperature Probe
EDDYTHERM operating manual Temperature probe The EDDYTHERM can be operated with automatic temperature detection using two different types of temperature probes. Magnetic probe This temperature probe [ETH 7305] is equipped with a powerful permanent magnet that attaches itself to any ferromagnetic material. - Page 20 The connector of the temperature probe is plugged into the connector next to the keypad (or to the right beneath the control panel in the 4x), and is locked with the threaded bushing. The EDDYTHERM recognizes the connected probe type and automatically limits the temperature programming to the highest allowable value in each case.

Page 21: Description Of Operating Modes And Functions
EDDYTHERM operating manual Description of operating modes and functions The EDDYTHERM offers three different operating modes to accommodate a wide range of user requirements, making it suitable for nearly any inductive heating task. Three operating modes 1. Temperature selection with automatic shutoff Set the desired temperature using the arrow keys. -
Page 22: Temperature Shutoff
A buzzer sounds to signal completion of the heating cycle. Step-by-step instructions: 1. Mount the workpiece on the EDDYTHERM. 2. Attach the temperature probe to the upper side of the workpiece. 3. Press the “temperature shutoff“ key. The associated indicator LED lights up. -
Page 23: Temperature Hold
It is automatically demagnetized before it is removed. Step-by-step instructions: 1. Mount the workpiece on the EDDYTHERM. 2. Attach the temperature probe to the upper side of the workpiece. 3. Press the “temperature hold“ key. The associated indicator LED lights up. -
Page 24: Timed Shutoff
Step-by-step instructions: 1. Mount the workpiece on the EDDYTHERM. 2. If the workpiece temperature is to be checked during heating, mount the temperature probe on the upper side of the workpiece. -
Page 25: Demagnetization
EDDYTHERM operating manual Demagnetization EDDYTHERM is equipped with a demagnetization circuit that allows demagnetization of ring-shaped workpieces independent of the heating process. Step-by-step instructions: 1. The ring-shaped workpiece is mounted on the swivel crossbar or regular crossbar (optional). 2. By pressing the “demagnetization” key, you can start the demagnetization process without first heating the workpiece. -
Page 26: Reduced-Power Heating Option
EDDYTHERM operating manual Reduced-power heating option In some special instances it may be necessary to heat a bearing slowly (for example, in bearings with a brass cage, where the brass cage heats up faster than the bearing). The reduced-power heating option slows down the heating process to allow all bearing components to heat evenly. -
Page 27: Faults And Error Messages
EDDYTHERM operating manual Faults and error messages EDDYTHERM is equipped with an overload protection (automatic fault detection unit) to prevent damage to the device or to the roller bearings being heated.
