TJ18, TJ22, TJ42, TJF42 & TJ80 Installation And Operating Instructions
An overheating of the electronic unit heat sink will
cause the compressor to stop. Restart will occur
automatically when a normal temperature has been
reached.
4.
Voltage Protection
If a voltage outside the operating range is applied
to the electronic unit, the compressor does not start,
or it stops if the voltage limit is exceeded during
operation. The compressor will restart automati-
cally approximately 1 minute after the supply volt-
age has reached the reset voltage within the range
in question.
5.
Battery Protection
The electronic unit provides protection as follows:
