Set the voltage divider PCB
The factory setting on the voltage divider PCB is 50:1.
To change the voltage divider to a different setting, set the DIP switches to one of the following:
NOTICE
The voltage divider PCB is a simple resistive divider of raw arc voltage. To prevent ground loops and
electrical interference, you must isolate the divided arc signal.
NOTICE
The factory-installed voltage divider PCB supplies a voltage that is in proportion to the arc voltage. The
DIP switch settings on the voltage divider PCB control the output in open circuit conditions, to a
maximum output of 16 V. This output is an impedance-protected, functional extra-low voltage (ELV)
output. This type of output prevents shock, energy, and fire under normal conditions at the machine
interface receptacle and in single-fault conditions with the machine interface wiring. The voltage divider
PCB is not fault tolerant and ELV outputs do not comply with safety extra-low voltage (SELV)
requirements for direct connection to electrical devices.
