Low Air Pressure
There is an air pressure gauge mounted on the main regulator at the rear of the machine, which may include
a low pressure sensor. This is designed as a gross check to verify the main air pressure is being fed to the
machine. This prevents damage to moving parts on the end effector. It does not detect slight fluctuations in
line pressure but it does detect brief dips below the set point. If such an instance occurs, the machine goes
to error for five seconds, then clears the error. The operator must either increase the air pressure or
decrease the set point to prevent such an error from happening again.
If any air pressure error is encountered, follow these steps to return the machine to normal operation:
1) Verify that the air pressure is ON.
2) Check that the main air pressure regulator is set for 80-100 P.S.I.
3) If the above settings are correct, and the output light indicator on the air pressure gauge is still lit,
verify the setpoint for the air pressure alarm. Consult the separate are pressure sensor manual for
information on setting the air pressure set point.
4) Adjust the set point for approximately 65-75 P.S.I.
5) Restart the machine. If the error persists, the air pressure sensor may be damaged.
Low Material Level
The workcell only checks the material level(s) when running cycles. If there is a material level error, the
machine can operate in all its modes (except for cycles) until the material level is reestablished.
Resetting the Exhaust Fan Overload Relay
Machines with exhaust fans may encounter errors when the overload relay trips. Follow these steps to
return the machine to normal operation:
1) Turn machine power OFF.
2) Open the electrical enclosure.
3) Check the tripped flag on the overload relay.
4) Verify that the current setpoint is set properly on the overload relay. Check the rating on the exhaust
fan housing for current draw.
5) If necessary, push the reset button to reset the relay.
6) Restart the machine. If the problem persists, consult the Troubleshooting section on page 38 for more
information.
Pneumatic Error Recovery Procedure
The system pneumatics are checked for errors any time they operate. In addition, any movements to home
or the standby position require the pneumatics to be in their “home” position before proceeding. If a
pneumatic fails, it generates an error such as the one below.
