Maintenance
Normally no maintenance is needed. But when there is a lot of snow, ice or other extreme
weather conditions, check so the sensors are not covered by snow and that the wind sensor can
rotate. The LCD screen should be cleaned with a dry soft tissue.
External inputs and outputs
Alarm input
When this potential free input gets low then the function will get active. When the Alarm
function is enabled and active all solar protection will be blocked in up position. Often the
buildings fire alarm system is connected to this input. The function is by default disabled. See
page 10 for more info about the function.
Lock inputs
When these potential free inputs gets high then the Lock via input function will get active.
When this Lock via input function is active all solar protection will be blocked in up position.
There is one input per zone. A connected key switch is often used to block the zone during
facade maintenance for example. See page 10 for more info about the function.
Manual command inputs
When these potential free inputs get high the Manual command via input function (up or
down) will activate. Stop is generated by a simultaneous up and down signal. This function
is equal to the manual push buttons on the control unit (see page 13). The inputs are IB
compatible meaning e.g. a Somfy Centralis switch can be used.
Error output
If an error would occur this potential free output will be activated (Low = Error). This output
is often connected to the buildings management system (BMS). See page 10 for info about the
function.
