SV91M Operating & Maintenance Instructions

SECTION 6: INDICATORS/FEATURES
6.1
Indicator
The degauss indicator is provided to give an indication of degausser coil energisation.
Certain circumstances can arise when, although the unit is switched on, the degauss coils
may not be energised.
6.2
Overheat Protection
The high energy field developed by the SV91M necessitates the generation of a
considerable amount of heat.
The degausser coil is monitored for excessively high temperatures and should this
condition occur its operation will be inhibited until the coil has cooled sufficiently.
6.3
Cooling
A thermostatically controlled cooling fan is provided to extend the continuous operating
period to a maximum.
6.4
Protection
The unit is protected by a thermal type circuit breaker. The current rating depends on the
specified operating voltage.
