3.6.2 ENVIRONMENTAL CONDITIONS
Important: SOLYS 2 rear cover
SOLYS 2 does not contain any user serviceable parts inside. Therefore it is advised not to open the rear
cover. Doing so can defeat the internal optical sensors which may result in physical damage to the SOLYS 2
and/or any attached equipment. Such damage is not covered under warranty.
Important: Precipitation
With the SOLYS 2 rear cover installed properly such that all 8 screws are secured, the SOLYS 2 is
environmentally protected to IP65, according EN 60529: 1991 + CI 1993. This qualifies the SOLYS 2 to be
used in weather conditions with all types of precipitation.
Important: Circuit breaker
A power on/off switch is not a part of the SOLYS 2; requirements for electrical equipment installed outdoors
specify that:
•
A power isolator (switch or circuit-breaker) must be included in the cable installation.
•
The isolator (switch or circuit-breaker) must be in close proximity to the equipment and within easy
reach of the operator.
• The isolator (switch or circuit-breaker) must be marked as the power disconnection device for the
equipment.
used in weather conditions with all types of precipitation.
3.6.3 USING A SOLAR PANEL TO POWER SOLYS 2
If the system is operating on solar power only, please be aware of the reduced number of hours of sunlight
during the winter
On cloudy days less than 50% of the normal radiation comes in
Rule of thumb is to use 10 times as much solar panel power.
How to determine what kind of solar panel is required; Please add the power consumption of each additional
instrument, PC`s, data logger or any other device together with the power consumption of the SOLYS2 and
multiply this by 10.
Power consumption SOLYS 2 on DC : 20W during sun cycle.
After the sun cycle, the SOLYS 2 will start its energy savings program and put itself to sleep mode.
During this sleep mode the power consumption is 13W.
20 minutes before the sun rises, the SOLYS 2 will wake up, go to its home position and starts its active
tracking mode with full power consumption.
If no other power is available, also a few days without sun should be covered by the back-up battery.
If the backup batteries are 2x12 V, they can be used in series for the SOLYS 2 (24 V)
