Troubleshooting
The ArcSwitch® meter is not working when the
Transmitter button is pressed.
• Check that the master switch on / off switch is
in the on position and the LED is lit green.
• Check the ArcSwitch® meter 9-volt battery is
connected and is new.
• Check the ArcSwitch® Transmitter 3 x AAA
battery is connected and is new.
• Check the ArcSwitch® Transmitter is in range of
the ArcSwitch® meter.
• Check the ArcSwitch® Transmitter led is lighting
up when pushing the button.
• Check the ArcSwitch® Transmitter is paired to
the ArcSwitch® meter.
• Check that the ArcSwitch® Transmitter and
ArcSwitch® meter serial numbers match.
The ArcSwitch® meter power contact sounds
weak when the on and off ArcSwitch® Transmitter
button is pressed.
• Remove the 9-volt battery from the mini snap
connector, replace with a new battery.
The ArcSwitch® meter power contact is closing
when the ArcSwitch® Transmitter button is
pressed but the circuit breaker is not closing or
opening.
• Check the leads are not broken on the
ArcSwitch® meter.
• Check the fuse by Bell testing across the
contact of the ArcSwitch® meter.
• Check that there is voltage on the terminals that
your ArcSwitch® meter is connected to and that
it matches the voltage of the opening or closing
coils.
• Check that the coil is not damaged or open
circuited or burnt out.
• Check to see that the circuit breaker is fitted
with opening and closing coils.
The control M.C.B. is tripping when ArcSwitch®
meter is connected to the control circuit.
• Check the ArcSwitch® meter is not connected
up wrongly and refer to your switchgear
drawings. DO NOT switch the positive directly
to negative or live directly to neutral across the
contact as you will be switching a direct short.
This could damage the contact by welding it
shut, and or blowing the fuse. You should only
be switching the live leg of the circuit.
• Bell test across the com input jack to the ground
jack on ArcSwitch® meter and if it is very low
resistance or bells, then the overvoltage
protection module has been subjected to a high
voltage transient and has been short-circuited.
