Cause: Voltage signal incorrect, calibration not possible
Measure during initial startup
Fault area 7:
Explanation: UR signal incorrect
Possible causes: Secondary voltage U2 outside of permissible range of 0.4…120 VAC.
check configuration.
Measure during operation, HBAbbreviation HB not changed
Fault area 4:
Explanation: Partial bypass (delta R)
Possible causes: Heating element partially bypassed by conducting part, e.g. clamp, opposite heat-sealing bar
Fault area 5:
Explanation: Parallel circuit interrupted
Possible causes:
- Wire break, heating element break.
- Contact to heating element is defective.
Fault area 6:
Explanation: Total bypass
Possible causes:
- Heating element incorrectly installed, no insulation at heat-sealing bar ends or insulation incorrectly installed
- Heating element completely bypassed by conducting part.
