SECTION 6: MAINTENANCE /SERVICING
The unit is basically maintenance free but periodic checks should be made to ensure the correct operation of the fan and the
good condition of the power cable.
NOTE:
To reduce the risk of shock hazard disconnect the degausser from the mains voltage supply before carrying out any
maintenance or servicing.
6.1 Circuit Breaker
To reset the circuit breaker simply 'push in' and 'release' the button.

Bulb Replacement
NOTE:
Remove Power from the unit before replacing bulbs.
1.
Remove the "bulb lens" from the "switch/indicator body" by levering it forwards.
2.
Remove the bulb from the rear of the "bulb housing" using a suitable extraction tool.
3.
Replace the bulb noting the following:
NOTE:
The bulb will fit in only one position in a locating slot. If when fitting this does not occur, remove the bulb and rotate it
through 180°.
4.
Refit the "bulb lens" to the "switch/indicator body" by gently pushing the lens into the "switch/indicator body" housing.
6.3 Cooling Fan
The cooling fan is of the conventional axial type powered from the ac voltage supply. The unit is over temperature and over
current protected and does not require servicing. However in the event of failure the fan may easily be replaced from the rear
of the degausser.
6.4 Internal Components
Most of the internal components are replaceable, i.e. the solid state relay, toroidal transformer and the thermal switches
mounted on the degausser coil. However the tuning capacitors and the degaussing coil are not spared items and if found
to
be faulty the unit should be returned to VS Security Products for repair. To access the components inside the degausser the
laminate cover must be removed. This entails breaking the adhesive using a sharp blade
6.4.1 Solid State Relay Replacement
A thermally conductive compound should be used to ensure adequate heat dissipation from the relay to the metal case.
6.4.2 Thermal Switch Replacement
Care must be exercised when replacing either of the switches on the degausser coil. The switches are fitted using an epoxy
resin and it is recommended that the new switch be fitted in a new position on the coil and the old switch be left in place. The
wire connections are of the 'push on' spade type and are easily transferred to the new switch. A high temperature epoxy resin
part no. EA200001 should be used to secure the new switch.
6.4.3 Cover Replacement
The laminate cover should be cleaned of old adhesive before refitting, using sealant part number EA100007 and high
temperature tape, part number HS100143
