Electrolyte
Additional option, ERROR 14 error output:
circulation option
Error detection (air pressure monitoring) is optionally available for electrolyte circulation.
(continued)
The charger multifunction panel displays an error message („Error 14") if electrolyte
circulation fails.
Important! If the electrolyte circulation pump does not have an optional error output:
-
If electrolyte circulation pump does have an optional error output:
-
Charge parameter switching: if electrolyte circulation fails, the charger alone ensures
sufficient mixing of the electrolyte.

The analysis lines can be connected to a PLC or a process control system.
The connections for the analysis lines are like no-voltage change-over contacts with a
common root. The following information can be transferred:

WARNING! An incorrectly configured data cable can cause serious injury
and damage. The galvanic isolation of the individual contacts is not designed
to provide safe circuit separation. The simultaneous use of low voltage and
mains voltage signals is therefore prohibited.
