When the inside temperature reaches approximately 18 °C, another temperature switch
turns the housing heater off and, if necessary, back on again (if the inside temperature drops
below 15°C). This does not interrupt the read operation. The front cover heater remains acti-
vated until an inside temperature of 25°C is reached. At temperatures above this, the front
cover heater switches off and, with a switching hysteresis of 3°C, back on again at an inside
temperature below 22°C.
Electrical connection
The required core cross-section of the connection cable for the voltage supply must be at
least 0.75 mm².
Attention!
The voltage supply must not be looped through from one device to the next.
Power consumption
The energy requirement depends on the model:
• the line scanner with heating typically consumes 40W and a maximum of 50W power.
• the line scanner with oscillating mirror and heating typically consumes 60W and a
maximum of 75W.
These values are based on operation with unconnected switching outputs.
