B2 – Installing the mechanical wiper on the OTT ecoN
Align the lower housing section (holes must line up) and place on the housing
tube of the OTT ecoN.
Attach the lower housing section to the OTT ecoN using the adjusting screw.
Fit the upper housing section on the OTT ecoN housing tube and attach using
the four hexagon socket screws supplied (size: 2.5 mm).
B3 – Electrically connecting the mechanical wiper
The connecting cable for the mechanical wiper is factory assembled for connection
to a switched supply voltage. Switching on the supply voltage starts the wiping
operation. If necessary, you can alternatively supply the mechanical wiper with a
constant voltage and start the wiping operation using a short trigger pulse.
Operating parameters for mechanical wiper:
Supply voltage +12 … + 24 V
DC
Power consumption max. 6 W
Wiping operation duration approx. 2 to 3 seconds
Gap between two wiping operations > 1 second
Recommended wiping interval 1 x daily
Trigger pulse length 100 ms
Trigger signal voltage range +5 … + 24 V
DC
Note:
The supply voltage must be applied until the end of a wiping operation. A
wiping operation is made up of two wiping cycles. The wiper blade is then in park
position. Otherwise the wiper blade may still be in the optical path, which leads to
unusable measurements.
