4.0 Operation
4.1 Power Up and System Checkout
Apply system power. One LED should light for each phase voltage
being monitored (see Figure 4-1). Single-phase and DC electrical
systems will light only one LED, split-phase systems light two LEDs,
while three-phase systems light all three.
If the connected LEDs do not light, remove power, check connec-
tions, and test again. If the LEDs still do not light, contact your sup-
plier.
4.2 Routine Operation
After system power has been applied, the SPD automatically begins
to protect down-stream electrical devices from damaging voltage tran-
sients.
With all AC phase voltages present, if an LED turns OFF, the SPD
has disconnected itself from that phase of the electrical system
because one of its Thermally Protected MOVs has failed. If a
Thermally Protected MOV fails, power will be maintained to the load;
however, the load is now
unprotected
.
The CVX050/100 is
not repairable
and contains no user serviceable
parts. If the unit fails, as shown by at least one of the LEDs turning
OFF, the unit must be replaced. Please contact your distributor as
the SPD may be under warranty.
WARNING
DO NOT USE THE SUPPRESSION CIRCUIT STATUS LEDS AS AN INDICATION
OF THE PRESENCE OR ABSENCE OF SYSTEM PHASE VOLTAGES.
Figure 5. Suppression Circuit Status LEDs.
1 LED per phase
LEDs that light
indicate MOVs
for that phase are
operational.
An LED that turns
OFF indicates a
failed MOV or loss
of power
