TROUBLESHOOTING
The hinged lid (I) is closed and the pusher plate
(L) down but the machine does not start when
the "Start" button is pressed:
- The machine is connected and the "Machine
connected to mains" (1) warning light is on. No
power reaches the plate or the plate is broken.
- In the CA-31 and CA-41 if the "Safety" warning
light (2) flashes slowly with the push- er plate
(L) down there is a problem with the pusher
plate (L) safety microswitch. This warning
could also be triggered in the CA-62 and
header. In the 2-speed machines the flas- hing
occurs in the "Speed 1" (5) or "Speed 2"
indicators (6).
- If the "Safety" warning light (2) flashes quickly
with the hinged lid (I) closed, there is a prob-
lem with the hinged lid (I) safety microswitch.
In the 2-speed machines the flashing occurs in
the "Speed 1" (5) or "Speed 2" indicators (6).
- If the "Machine connected to mains" (1) and
"Safety" (2) warning lights flash alternately, the
motor thermal protection device has tripped.
Wait for it to reset and investigate what the
problem could have been (overload, parts
FIG. 1
seized up, problems with starter relay or
capacitors in single-phase models etc...). In
the 2-speed models the flashing occurs
between the pilot lights "Machine connected to
the mains" (1) and "Speed 1" (5) if the speed
selected was slow. Or, the pilot light "Machine
connected to the mains" (1) and "Speed 2" (6)
if the speed selected was fast.
PLS. NOTE: In models equipped with an
emergency stop button, the pilot lights blink
in the same way. Verify the status of the
emergency stop button.
- To check that the keypad works properly, if you
keep one of the keys pressed down the
"Machine connected to mains" warning light
(1) should flash. If it does not the keypad may
be malfunctioning.
The machine was on and stopped without
pressing any key. If the machine is on, without
pressing the pusher plate (L) the machine stops
automatically after 30 minutes.
Note: In the CA-62 there is no pin, therefore
after 30 minutes the machine stops auto-
matically. To restart the machine simply
press "On" (3).
NOTE: The electronic board has the follo-
wing lights and indicators:
- Power: Lights up when there is voltage in the
board.
- SEG: Lights up if all the safety devices are
closed.
- RL1, RL2, RL3: They light up when the
corresponding relay closes its contact.
- Switch SW1: Position OFF cutter 1 speed.
Position ON cutter 2 speeds.
- Fus1-Var1: The board has a fuse and a pro-
tection varistor.
The motor does not start when the pusher plate
is pressed down:
- If the pusher plate (L) is left open for more than
30 seconds, press "Start" (3) again to reset the
machine.
- In the CA-31 machine the hopper might be too
full and the pusher plate does not activate the
microswitch. Empty part of the hopper and try
again.
If the machine makes too much noise or the disc
(A) rubs against any part, the main axle bearings
are probably damaged.
