Page 11: Imbalance Switch
Imbalance switch • A switch detects any imbalance. • Imbalance can only be detected in running mode (starting, centrifuging and braking). • If any imbalance is detected, the drive is changed over to braking. Interlocking • Opening of the LL is prevented by a latch. The LL can only be opened when the relay on the SB is energized by the CP. -

Need help?
Do you have a question about the ROTINA 38 and is the answer not in the manual?
Questions and answers
What should I do when the mains interrupt
The manual does not explicitly describe steps for handling a mains interrupt on the Hettich ROTINA 38. However, if the issue involves the mains choke coil causing an error (e.g., FU / CCI - ERROR 62) due to undervoltage, the procedure is as follows:
1. Pull both plugs from the mains choke coil.
2. Cut off both plugs and connect the ends of the cables together using a luster terminal.
If additional troubleshooting is required, consult the troubleshooting or error message sections of the manual for further guidance.
