Installation, Maintenance, Service & Part List Manual
Air pressure not set Check the air regulator is set to 90psi.
Air pressure sensor not working Check the air pressure sensor is set to 60 psi. Check that the
computer module sees the air pressure input. A green LED should
be on.
Computer module failed See computer module diagnostics, section 5.3
4.5.2 Status Light is not functioning correctly
The status light is used to identify the state of the machine in Load Tools or RUN mode:
•
Steady light: A program is running or tool change in progress.
• Flashing light, once per second: The machine is waiting for operator input or a RUN is over.
• Flashing light, 3 times per second: There is a fault on the machine.
Do the following Service Code:
•
Code 521 – Input/Output Service Code
Possible Cause Check This
Status light failed If the computer module output LED for the status light is on then
the light or bulb may have failed.
Computer module failed See computer module diagnostic, Section 5.3
4.5.3 Lube pump not working
Lack of lubrication can lead to problems with machine motion due to increased friction and play on the
sliding ways. This lube pump is set to lubricate the sliding ways and ball screws upon initial power up of
the control and every 30 minutes of axes movement. The control monitors the lube pump for oil level and
pressure and will produce an error when either are a problem.
Do the following Service Codes and procedures:
•
Code 300 Manual turn on pump
Possible Cause Check This
Lube pump fuse has blown Check the fuse on the lube pump and manually turn on pump with
service code 300
Cable or connection problem Check cable connection at pump and computer module.
Computer module failed See computer module diagnostic, section 5.3. You can remove the
lube pump connector from the computer module and measure for
115 VAC when you turn the pump on with service code 300.
4.5.4 Z Axis Motor Brake is not working
The 2 OP has no counterweight to support the head when the servos are off. The Z motor has a brake that
comes on whenever the power to the servomotor is turned off. If this brake fails and does not engage, the
head will move downward. If the brake does not turn off, the motor will most likely fault out due to the
extra load.
When there is no power to the brake, the brake is on (engaged).
Possible Cause Check This
Computer module failure Identify the status of the Z axis brake light on the computer
module. When the brake is off, the light should be green. See
computer module diagnostics, section 5.3
Motor brake has failed Replace motor brake. A 24 volt signal should turn the brake off,
which means the head is free to move.
