counter is adjusted at 10 seconds from the factory (which is typically satisfactory for an average line speed up to
120 CPH but may vary according to your car wash line speed: faster the line speed = lower value (in seconds).
TOP WHEEL
REVERSE TIMER
regulate the time period (starting after the front of the vehicle crosses the sonar
ready signal photo-eyes) that the top wheel will monitor the “
Torque
” applied to the motor and will reverse the
rotation in the event where the brush would get “jammed” or “caught” on the front end of a vehicle equipped with a
unconventional accessory or on a vehicle equipped with a particularly straight (vertical) windshield. Increasing the
number (in seconds) increases the window time period and area monitored by the top wheel reverse system.
OPEN BED DETECTED
timer delays the reaction time of the top wheel extends and retracts after an open bed is
detected on a full size pick-up truck. The counters are pre-set at 2 seconds for
ON DELAY
and 3 seconds for
OFF
DELAY
from the factory and is typically satisfactory for an average line speed up to 120 CPH but may vary

SIDE WHEELS SAFETY SETTINGS:
The
SLOWDOWN
feature slows the side wheels to a safer RPM while drying the antenna/mirror area. Only one
adjustable timer is used for this feature:
SLOW SPEED
which is the duration of the slower speed from the time of
the
SIDE WHEELS READY SIGNAL
is received to the area beyond the antenna/mirrors area. The timer is typically
set at 5 seconds from the factory and seems to be sufficient for most car washes.
HOOD SENSING SAFETY SETTINGS:
Your Dry N’Shine has two user selectable methods to detect the height of a tall front end (tall hood) on an oversized
pick-up truck for example. The first one is using the
HOOD SENSOR PHOTO-EYES
and is typically the preferable
one and also the default one from the factory. The
ON TIME
timer in the
HOOD SENSING BOX
(see Picture #70
and 71) determine the duration of the sensing of the hood (in the front of the vehicle) or how long (in seconds) the
HOOD SENSING PHOTO-EYES
will be enable in front of each vehicle before determining if the hood is high.
During that period of a few seconds (5 seconds programmed below) if the photo-eye beam is broken, the photo-eye
send a signal to an air solenoid valve located on the top wheel and raise the top wheel to a safer starting height
preventing then the top wheel from getting stuck on the grill of a large pick-up truck. The counter is adjusted at 10
seconds from the factory (which is typically satisfactory for an average line speed up to 120 CPH but may vary
according to your car wash line speed: faster the line speed = lower value (in seconds).

IMPORTANT NOTE:
ADJUST THE REVERSE WINDOW ON TIME TO ONLY COVER THE FRONT
AND THE ROOF OF AVERAGE VEHICLE. AVOID THE TOP WHEEL FROM
BEING ABLE TO REVERSE IN THE REAR AREA OF VEHICLE
IMPORTANT NOTE:
DO NOT KEEP THE TOP WHEEL COUNTERBALANCED TOO LONG BEYOND
THE WINDSHIELD. DOING SO MAY PREVENT THE TOP WHEEL TO COME
DOWN ON THE TRUNK OF A SEDAN STYLE VEHICLE, IMPAIRING THE
OVERALL PERFORMANCE OF YOUR DRY N’SHINE
