11.2 SPECIFIC LINE ITEM CHECK IS SHOWN BELOW
Ready LED is off
(unit not ready)
Ready LED is off
(unit not ready)
The auxiliary supply
voltage is absent.
Check pins 2 and 3 on KM1003 to confirm proper
input voltage is applied.
The magnetic
actuator is damaged
or not connected.
Check the magnetic actuator circuit. Unplug the
magnetic actuator from the plug to the left of the
mechanism (MA). There are two Phillips head
screws that keep the plug held together. The top
two wires are red and the bottom two wires are
blue. The top red (43) and top blue (45) wire go
to the "On" (close) coil. The other two wires go to
the off (open) coil. Each of these coils should
read approximately 0.3 ohms.
The breaker position
is not being read
correctly.
When breaker is closed verify I1001 shows
18Volts from terminal 1 to terminal 5 and
approximately 0 volts from terminal 2 to terminal
6. Reverse this procedure if breaker is open, 0V
terminal 1 to 5, 18V terminal 2 to 6.
The Under Voltage
(UV) function is
enabled and input is
open.
Inspect dip switch I1004. Ensure switches 2, 3, 4
and 5 are in the off (down) position (disables UV),
or apply correct input voltage to pins 13 and 14
on KM1005.
The UV function is
enabled and the
monitored voltage is
connected to the UV
input, but the voltage
is lower than the
threshold.
Set the correct UV threshold level via DIP switch
I1001 or disable UV by putting switches 2, 3, 4
and 5 in the off (down) position on I1004.
The auxiliary supply
voltage has been
turned off and the
voltage on the
capacitor is under the
O-CO levels.
Check pins 2 and 3 on KM1003 to confirm proper
source input voltage is applied.
The control panel is
damaged or not con-
nected correctly.
Verify the control panel 6-pin plug is plugged into
KM1007.
