10.4 Vibrator Valve Test
The vibrator runs on every cycle when the feed screw is turning. If the
vibrator is not moving, first check the air pressure to the vibrator.
1. Close the air needle valve and disconnect the air line from the supply side
of the valve.
2. Open the needle valve slowly and check for air pressure on the supply
line.
• If there is no pressure, check the pneumatic connection to the
machine.
• If there is pressure, close the valve, reconnect the air line to the valve
and open the valve.
Then check the mechanical function.
1. Disconnect the air supply tube from the solenoid valve on the support
beam and apply compressed air to the tube.
• If the vibrator is working properly, it should start to vibrate when
compressed air is applied.
2. If the vibrator is working, reconnect the air line to the valve and
disconnect the valve cable. Apply 24 VDC to pin 1 and 0 VDC to pin 2.
• The valve should open and the vibrator should start to vibrate.
• If the valve does not move, replace the valve with a known good one.
10.5 Control System Alarms
The control system has several features, which provide an early diagnosis of
faults in the control system.
• If the system detects any malfunctions, it displays an
error
message
on the Alarm screen.
• If the system detects any abnormal condition it displays a
warning
message on the Alarm screen.
