LED STATUS INDICATOR
When the Hydro-Wiper is switched on the LED status indicator will
blink 4 times and then a wipe will be performed. During
deployment the LED will blink every 15 seconds. The number of
blinks indicates the performance status of the Hydro-Wiper as
shown in table 4.
DURING DEPLOYMENT
Unpredictable events can happen during a deployment. The Hydro-
Wiper has been designed to withstand the harsh nature of field
deployments.
•
The wiper drive shaft features a slip mechanism, so the
wiper arm can be manually moved if necessary without
causing any damage. This also protects the wipe
gearbox from damage in the event the wiper arm is
subject to force or shock loading during deployment.
•
The Hydro-Wiper routinely monitors the position of the
wiper arm. If the wiper arm is moved from the park position,
the Hydro-Wiper will detect this and move the wiper arm to
one side.
•
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 unsuccessful,
the Hydro-Wiper will abort the wipe. The diagnostic LED will
flash twice every 15 seconds whilst this situation continues.
