The timing of the wipe is optimally just prior to making a
measurement with the OBS3+. It is recommended that a small time
interval occurs between the wipe and the measurement, to allow for
settling of debris dislodged during the wipe.
If the wiper arm becomes jammed at any stage during a wipe, the
direction of rotation will be reversed in an attempt to dislodge the
obstruction. If this is un-successful after a number of attempts, then
the Hydro-Wiper will abort the wipe. As a result, the Hydro-Wiper is
not damaged by a jammed wiper arm.
The wiper control module features an LED. On power-up, the LED
will flash once. The LED will then flash once every 10 seconds. If the
wiper arm becomes jammed, and the wipe is not completed
successfully, the LED will flash twice every 10 seconds, until the
wiper arm becomes free and a successful wipe is completed.
