Malfunctioning; Cleaning & Maintenance - Bessey PV Series User Manual

7.4 Malfunctioning


If the temperature of the work piece fails to increase by 1º (either C or F) within a set time-
span, the heater switches off automatically. Four blinking dashes will appear (----) in the
display, and a loud intermittent beep is emitted. Press the 'STOP' key to stop the beeping and
check whether:

the probe is still attached to the work piece, and is connected correctly into its socket.

the probe wiring has been damaged.

the probe surface is clean.

the heater capacity is too small for the work piece.
If the probe is defective, the Time Mode can still be used. The temperature should be checked
using an external thermometer.

If a loud vibrating noise is heard, first check to see that the contact surfaces of the yokes are
greased sufficiently. Then check to see that the yoke is making optimal contact with poles. (To
adjust yokes: Place yoke on heater, unscrew the bolts in the yoke ¼ turn. Switch on heater
and the yoke will set itself. Re-tighten the bolts. You can also use a nylon hammer as an aid to
reposition the laminates).
7.5 The Induction heater can be used in °C or °F.
To change this follow steps:

Press the temperature button for 10 seconds, you will hear a short "bleep".

Then wait, after another 10 seconds a second "bleep" will sound and in the display the
temperature mode will switch from Celsius to Fahrenheit or vice versa.

The heater is now ready for use in the newly set temperature mode.
WARNING!
 If in any doubt, isolate the machine and contact your local distributor.
8. Cleaning and Maintenance

Store in a dry, frost-proof area, free from humidity.

Keep clean with a soft, dry cloth.

Keep the contact parts of the poles clean. Grease regularly with an acid-free grease for
optimal contact with the yokes and to prevent corrosion (on swing-arm models, also grease the
vertical pin regularly).

Contact your supplier if there is any suspicion of malfunctioning.
WARNING!
 Proper maintenance and handling practices are critical. Failure to follow installation
instructions and to maintain proper lubrication can result in equipment failure, creating
a risk of serious bodily harm.
