10. General operation
The Steamtec II Basic steam generator does not have an own on/off switch and remains always
connected to power supply. The steam production is switched on or off from an external control
unit (switching signal on input terminals Wb, S1 and N). An external control unit does not belong
to the delivery scope of the steam generator and shall be purchased separately.
The steam generator with a removed housing may be also disconnected from power by switch-
ing off the F1 fuse. It will not start heating in such case and will not consume power. However
various components and terminals will still remain connected to power and will not be power-
less.
Steamtec II Basic steam generator will display the operation states and common malfunctions by
flashing of the main operation LED (pilot lamp) on the bottom housing of the unit (see page 12).
The pilot lamp is off if the generator is off. During active heating the pilot lamp will illuminate
continuosly. For troubleshooting of the possible malfunctions please see “Troubleshooting”.
