Part 1 of 3: Troubleshooting

The errors are reported as faults.

The analog output emits constant voltage, the level of which is associated with a set of error codes.
ALARM LED remains illuminated.
Alarm relay is active.

Error code	Analog signal voltage [V]	Cause	Measure during initial startup	Measure during operation, HB¹⁾ not changed
101	0.66	Current signal missing	Fault area `1`
102	1.33	Voltage signal missing	Fault area `3`
103	2.00	Voltage and current signals missing	Fault area `2`	Fault area `2` and `9`
107	2.66	Temperature drop	Fault areas `4`, `5` and `6` (loose contact)
108		Temperature spike	Fault areas `4`, `5` and `6` (loose contact)
307		Temperature too low, tolerance band was left	Check the dimensioning of the pulse transformer. Check heat extraction through the sealing process. Verify application through sealing tests.
308		Temperature too high, tolerance band was left
309		Temperature too low, tolerance band was not reached
310		Temperature too high, tolerance band was not reached
201	3.33	Line frequency missing/fluctuates	Check mains power supply: Line frequency Harmonics Voltage fluctuations
202		Line frequency too high/fluctuates
203		Line frequency too low/fluctuates
304	4.00	Heat-up time too long	Reset device. Check dimensioning of the pulse transformer. Check parametrized heating time. Check lines and contacting.	Reset device. Check lines and contacts. Check sealing process.
305	4.00	Starting temperature too high	Reset device. Verify cooling system. Check maximum starting temperature.
901	4.66	Line voltage/synchronizing signal missing	Check line voltage
913		Triac defective	Replace device.
914 915		Internal error: Comparator in measuring module defective
916		Internal error: Test mode not ended successfully
917 918		Slide for alarm output not plausible.	Check slide.
919		Internal error: Comparator in measuring mode not plausible	Replace device.
920		Voltage signal not plausible Internal error: Voltage change-over in measuring module defective	Check heating circuits: Check Relay Kb. Check voltage signal. Do not interrupt voltage signal during AUTOCAL. Reset device. Restart AUTOCAL. Replace device.
930		Internal communication module does not reply when temperature controller is switched on	Switch device off and then on again. If the error code appears repeatedly, replace device.
931		Internal communication module indicates an error when temperature module is switched on
932		Internal communication module does not reply during operation
933		Internal communication module indicates an error during operation
934		Internal communication module does not reply during operation
935		Communication module firmware is not plausible (does not match device type)	Replace device.
937		Internal communication module not started correctly	Switch device off and then on again. If the error code appears repeatedly, replace device.
938 939 940 941²⁾		Internal error: Capacitor in measuring module defective	Replace device.
