SPECIFIC LINE ITEM CHECK IS SHOWN BELOW:
PROBLEMS
Ready LED is off
(unit not ready)
POSSIBLE CAUSES
The auxiliary supply
voltage is absent.
The magnetic actuator
is damaged or not
connected.
The position sensors
are damaged or not
connected correctly.
The Under Voltage
(UV) function is
enabled and input is
open.
The UV function is
enabled and the moni-
tored voltage is con-
nected to the UV input,
but the voltage is lower
than the threshold.
The auxiliary supply
voltage has been
turned off and the volt-
age on the capacitor is
under the O-CO levels.
The control panel is
damaged or not con-
nected correctly.
POSSIBLE SOLUTIONS
Check pins 2 and 3 on KM1003 to confirm proper
input voltage is applied.
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 the bottom two wires are blue.
The bottom red (43) and bottom 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 between 0.6 -1.0 ohms.
There are 3 wires connected to the proximity sen-
sors- Black is the signal wire, Brown is connected
to +18 volts and Blue is connected to ground.
When metal is placed in front of a sensor, it will
be picked up and you will see the yellow LED lit
on the back of the sensor. From the black wire to
the blue wire verify it reads +18V. When the
metal is removed the voltage should drop to near
0.
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.
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.
Check pins 2 and 3 on KM1003 to confirm proper
source input voltage is applied.
Verify the control panel 6-pin plug is plugged into
KM1007.
