Fault Recovery Procedure
226B225B225BSeveral errors can cause a fault condition. They are:
• 125B124B124BThe EMERGENCY STOP is engaged or there is an open door
• 126B125B125BThere is an exhaust or intake fan failure
• 127B126B126BThe parameters are out of range
• 128B127B127BThe module is over-temperature
• 129B128B128BThere is a solid-state relay failure
227B226B226BThe following sections show an example of a machine error. For a complete list of error
messages, refer to Section 11.
Recovery from Emergency Stop or Open Door Error
228B227B227BIf the Emergency Stop button is engaged or the machine has a system error, perform the
following procedure to return the machine to the cycle stop state.
285B284B284BWARNING: If the Emergency Stop was engaged because of system failure, do not
disengage the Emergency Stop. Shutdown the system and have qualified personnel
repair the machine.
1. 130B129B129BDisengage the Emergency Stop button or close all doors.
2. 131B130B130BSelect “Clear Fault”.
Recovery from an Exhaust or Intake Fan Failure
1. 132B131B131BSelect “Clear Fault” to stop the alarm or “Reset” to clear the fault.
2. 133B132B132BOperate the fan in Manual mode to make sure the components operate correctly.
Recovery from a Parameter Out of Range Error
1. 134B133B133BSelect “Silence Horn” to stop the alarm or “Clear Fault” to clear the fault.
2. 135B134B134BOperate the module in manual mode or restart the Auto Cycle. Look for the
parameter that causes the error.
3. 136B135B135BIf the error continues to repeat, refer to Section 12.

Recovery from an Over-Temperature Error
1. 137B136B136BSelect “Silence Horn” to stop the alarm or “Clear Fault” to clear the fault.
2. 138B137B137BLet the module temperature decrease.
3. 139B138B138BOperate the module in manual mode or restart Auto Cycle. Look for the parameter
that causes the error.
4. 140B139B139BIf the error continues to repeat, refer to Section 12.
Recovery from an Auto Conveyor Adjust Error
229B228B228BIn the conveyor homing procedure, two errors may occur:
230B229B229BError 1: The conveyor passes the home position sensor and hits the hard stop on one side.
1. 141B140B140BWhen the conveyors pass the sensor and hit the hard stop, engage the “Emergency
Stop” button.
2. 142B141B141BOpen the left cabinet and find fuse number 70.
3. 143B142B142BRelease the fuse and disengage the “Emergency Stop” button. This will move the
conveyor toward the sensor.
4. 144B143B143BWhen the conveyor passes the sensor, engage the “Emergency Stop” button again.
5. 145B144B144BExamine the integrity and the wiring of the sensor.
6. 146B145B145BInstall fuse number 70, and home the conveyor again.
231B230B230BError 2: The conveyor passes the software limit and hits the hard stop on the other side.
1. 147B146B146BEngage the “Emergency Stop” button.
2. 148B147B147BOpen the left cabinet and find the conveyor direction relay (CR11).
3. 149B148B148BPull the blue button and disengage the “Emergency Stop” button. The conveyor
will move away from the hard stop.
4. 150B149B149BEngage the “Emergency Stop” button again. This will stop the conveyor.
5. 151B150B150BPush the blue button so it is in the original position in the relay.
6. 152B151B151BExamine the wire and the conveyor position encoder.
