2.8. Alarm device:
The machine is standardly equipped with an alarm device which will indicate any
fault at the snowmaker.
With the alarm device the motor protection switches for fan and the compressor
motor are monitored. At the water separator, there is a pressure switch for
monitoring the air pressure. The air pressure necessary for operation is only
reached by the corresponding counterpressure of the water. Herewith the alarm
device is also activated in case of problems with the water supply (lacking water
pressure or defective hose).
Faults will be signalled by a flash light.
Make sure that the flash light is activated when starting the snowmaker (because of
too low air pressure), but under normal function it may not be activated.
2.9. Automatic swivel mechanism:
The actuation is made via a gear motor which activates the rotating assembly, on
which the machine is mounted, by means of a cogwheel.
The drive is mounted in a floating position and can be declutched for manual
function. Herewith the machine may be brought into the desired position without
power supply (e.g. for transport of the snowmaker).
The swivelling angle is monitored by a counting wheel at the gear motor by means
of a proximity switch. The desired swivelling angle can be reset with 10°, 16°, 24°,
30°, 38°, 44°, 52° and 60° via a switch with 8 positions.
For automatic machines, the control of the swivel mechanism is made via the
automatic control unit STF. The swivelling angle can directly be registered in ° on
the keyboard.
2.10. Automatic system:
All SUFAG
®
snowmakers are available with an automatic control for fully automatic
function.
The configuration and the mode of operation of the automatic system STF are
described in a separate operating manual.
2.11. Soft starter function - fan motor:
SUFAG
®
snowmakers are, depending on the modell, either equipped with Y-D or
a soft starter function of the fan motor.
Motor protection settings:
9 kW fan motor 18A
5 kW fan motor 30A
If an error occurs, the LED-lamp flashes up to 7 times in a row depending on the
