FAULT light
The FAULT light will illuminate in response to any fault condition and will
mirror the Any Fault Alarm. It also indicates that the Any Fault Alarm relay
contacts are in fault condition, activating any accessories that are
connected. If the Any Fault Alarm output function is configured to the
LCH mode the fault light will remain on, otherwise the FAULT light will
turn off automatically. The FAULT light can be turned off in 3 ways: (1) by
pressing the “R” button below it; or (2) by closing a momentary switch or
relay contacts wired between Pins 1 & 3 of 9-Pin green panel terminal
block on the rear panel; (3) though one of the serial communication
interfaces.
“R”
RESET button
Pressing the “R” button will reset all fault conditions and
their
corresponding Relay output. The RESET button will have no effect on the
number of faults registered on the fault counter.
High Voltage On Lamp
The high voltage On Lamp will turn on when the high voltage
output level is above 500V.
Bead Chain Electrode
When the spark tester power is ON and the clear protective cover is
down, the test voltage set on the spark tester front panel is applied to
th
e product under test as it runs through the electrode. 1”, 2”, and 3”
bead chain electrodes are available. Other electrodes are available.
Please contact factory for details.
Clear Protective Cover
The clear cover protects the operator from coming into contact with the
energized electrode.
Safety Interlock switch
This switch turns OFF the high voltage in the electrode when the clear
protective cover is lifted. Do not attempt to defeat the safety interlock
switch.
Safety end guards
Metal end guards on each end of the high voltage test module prevent
the operator from reaching into the energized electrode. The test
product should be centered in the electrode to avoid damage to the
product.
