Chapter 8: Troubleshooting
• Code A1_3 - LOAD CELL / CAL SELF CHECK ERROR
Calibration level voltage error after a press start was attempted.
CAUSE:
1. When the load cell is sensing excessive force due to pressure or vibration during the press
cycle start.
2. If the controller or the load cell cable is located in an electric or magnetic noise field.
3. When the load cell, load cell cable or the controller malfunctions.
RECOVERY:
1. Check that the press shaft has no external force applied to it.
2. Verify the tool mounting bolts are tight and nothing is causing excessive vibration to the tool.
3. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and attempt again a press start input.
4. Exchange load cell cable, tool and/or controller with known working units. Input the start
signal after each exchange, and make note of any change in the location of the abnormal.
5. Replace the defective component.
• Code A1_4 - LOAD CELL / STARTED ON ZERO ERROR CONDITION
The start signal was input while a Zero voltage abnormal condition existed.
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the ZERO VOLTAGE ERROR abnormal help procedure.
• Code A1_5 - LOAD CELL / STARTED ON CAL ERROR CONDITION
The start signal was input while a Cal voltage abnormal condition existed.
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the CAL VOLTAGE ERROR abnormal help procedure.
• Code A1_6 - LOAD CELL / ZERO LEVEL SELF CHECK ERROR
Zero level voltage loaded to memory from tool EEPROM during initialization does not match the
actual zero level during a self check with the self check function enabled.
CAUSE:
1. When the load cell is sensing excessive force due to pressure on the press shaft.
2. If the controller or the load cell cable is located in an electric or magnetic noise field.
3. When the load cell, load cell cable or the controller malfunctions.
RECOVERY:
1. Check that the press shaft has no external force applied to it.
2. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize.
3. Exchange load cell cable, tool and/or controller with known working units. Reinitialize the
system after each exchange, and make note of any change in the location of the abnormal.
4. Replace the defective component.
