9.6 Switch/Safety Interlock
The steam generator is only operative when terminals 1 and 2 are
bridged. In case of neither a remote switch nor a safety device wired
across terminals 1 and 2, a wire bridge must be inserted.
The steam generator is only allowed to start operation if the contact
between terminal 1 and 2 is closed. If neither a remote switch nor a
safety device are wired to terminal 1 and 2, a wire bridge must be
installed.
Factory setting has no wire bridge across terminals 1 and 2.
For switching the HygroMatik steam generator on and off remotely, a
remote switch is to be connected across terminals 1 and 2. With the
switch closed the steam generator is operative. When opening the con-
tact across terminals 1 and 2, the steam generator ceases operation.
The wire loop across terminals 1 and 2 is used for safety interlock.
Safety devices such as an emergency shut-off switch or a max.-ther-
mostat may be wired in here.
Risk of scalding due to steam overheating in cabin caused by
temperature sensor failure!
Installation of a max-thermostat in the saftey interlock is strongly
recommended.
If both a circuit protection device and a remote switch are to be used,
wiring is in series.
