PROBLEMS POSSIBLE CAUSES POSSIBLE SOLUTIONS
Ready LED
is blinking
The circuit breaker is closed
and the close coil is
disconnected or broken.
In this case, only the opening operation is available;
open the circuit breaker (the ready LED will be
turned off) and check the closing coil 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 coil should read between
0.6 -1.0 ohms.
The auxiliary supply voltage
has been turned off.
If the circuit breaker is closed you can perform a
CO-operation; connect the auxiliary supply. Check
pins 2 and 3 on KM1003 to confirm proper input
voltage is applied.
The capacitor bank is
]charging during start up or
after an operation.
Wait a few seconds.
The opening
command is
not performed
The opening coil is broken or
damaged.
In this case, only the closing operation is available;
open the circuit breaker (the ready LED will be
turned off) and check the closing coil circuit.
Disconnect the magnetic actuator from the plug to
the left of the mechanism. 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 "Off" (open) coil. The coil should read between
0.6 -1.0 ohms.
The capacitor bank is not
connected.
Check the capacitor bank circuit. Verify the capaci-
tors are connected to the control board. Ensure that
there is 80 VDC across KM1002 terminals 1 and 3.
No external opening input is
connected.
Verify opening input is wired.
The control panel is either
damaged or not connected
correctly.
Verify the control panel 6-pin plug is plugged into
ED2.0 switching circuit board Replace ED2.0 board
All indication
output contacts
are open
The voltage on the capacitor
bank is under 46 VDC.
Connect the auxiliary power supply voltage.
Capacitor bank is not
connected.
If it happens immediately when the supply voltage is
switched off and the ready LED is immediately
turned off, check the capacitor bank circuit.
