8.3 AUTOMATIC configuration
To set up the unit as AUTOMATIC the same instructions for the set up as MASTER must be followed (see paragraph
8.1 MASTER configuration). Adjust the dip-switch Master to ON and choose the programme to be executed.
An internal temperature sensor prevents the unit from overheating. The temperature sensor will limit the current
to leds, protecting their integrity, if the ambient temperature exceeds the one allowed.
To ensure maximum functionality and light output it is recommended to follow these instructions:
10.1 Cleaning the unit
10.1.2 Fixture body
The unit must be cleaned regularly. Cleaning regularity will depend especially on the environment where the unit
will operate: deposits of dust, smokes or other wastes will reduce the light output performances.
• Clean regularly the glass of the unit.
• Be careful when cleaning the components. Operate in a clean, properly illuminated environment.
• Do not use solvents which could damage painted surfaces.
• Remove left particles by a cotton towel dampened with a glass-cleaning liquid or distilled water.
• Remove smoke and other wastes by a cotton towel dampened with isopropyl alcohol.
• Dry out by a clean, soft, non-scratching towel or by compressed air.
12.1.2 Fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this periodic cleaning will
depend, of course, upon the conditions in which the projector is operating. Suitable instruments for performing this
type of maintenance are a brush and a common vacuum cleaner or an air compressor.
10.2 Regular checks
• Check electrical connections, especially the ground wiring and the power supply cable.
• Check that the unit is not damaged mechanically. Replace those components which have got deteriorated.
All components of the unit are available as spare parts at
Griven
dealers.
Exploded views, wiring diagrams, electronic layouts and advertising brochures are available on request.
To make the job of assistance centres easier, specify serial number and model of the unit which spare parts are
requested for.
