Page 9: Overload Protection
The trip levels are adjustable in two ranges each of 6 steps giving 2-12% and 20-120% rated current. Trip current ranges Unit KV5-100 mk3 2, 4, 6, 8, 10, 12mA 20, 40, 60, 80, 100, 120mA The range change and selector switches are located on the front panel of the instrument. The circuit will activate when the load current exceeds that set by the trip level selector switch. -
Page 10: Metering
The equipment is provided with the following metering ranges using analogue moving coil meters: Metering Ranges Unit Voltage Current High KV5-100 mk3 10mA 100mA The ranges on both instruments are selected by means of switches located on the front panel. -
Page 11: Fault Burn Facility
Fault Burn Facility The KV5-100 mk3 is provided with an internal current limit circuit which limits the output current from the unit under short circuit conditions. This can be used to “burn” faults. 1.5.1 Fault Burning Fault burn is where the arc is maintained through the failed test object. The product does this by limiting the current and preventing the unit from tripping. -

Remove and rotate fuse carrier until desired supply voltage is seen through the fuse drawer window. The KV5-100 mk3 is suitable for 2 different supply voltages as follows: 240V or 115V. Replace fuse drawer once the desired voltage has been selected. -
Page 13: Operation
Safe working procedures must be implemented to accepted standards. 2.1.2.1 Interlocks The KV5-100 mk3 series is provided with an external interlock circuit that may be used to link to interlock switches on the high voltage test area. An interlock should be considered to be a safety back-up feature. An interlock should not be regarded as a substitute for adequate safety rules and proper operator vigilance. -

2.4.2 Operation Switch on the key-operated mains switch. The following will now occur: Power ON lamp will be lit HV OFF lamp will be lit The variable overload reset lamp will be lit Press the variable overload reset push button. This will arm the trip circuit. Select the desired voltage range on the kV meter and set the desired overload trip level. - Page 17 MAINTENANCE Maintenance and repair of the KV5-100 mk3 series must only be carried out by suitably qualified and trained personnel. Potentially lethal voltages are present inside the unit and on the output leads. Ensure that the unit is disconnected from the mains before removing WARNING any covers.
