Cam Timer Adjustment
Timers are available with 6,7, or 8 cams .
Cycle time is not adjustable
Timer cams (wheels) are fixed or adjustable. Each cam controls a specific function, as noted on the timer decal. Adjustable
cams are comprised of two (2) wheels. The outer edge of each wheel (half) has a high and low segment. When the wheels
are rotated, the two low segments can form a notch. Above each cam is a timer switch with a metal finger that rides on the
cam. When the finger drops into the cam notch, the function of that cam begins. To widen (length = time) or close the notch,
use timer adjustment tool (provided). This tool has two (2) raised buttons that fit into the holes on each wheel. The factory
sets the start of each function using the right-side of the cam. TO ADJUST rotate only the left-side cam wheel. The
left-side of the wheel controls when that specific functions stops.
#1 Cam: The white cam on your left is the master cam. It controls the total time of the cycle and is not adjustable.
#2 Cam: Continuing left to right, this black cam controls detergent. The detergent cam is adjustable.
#3 Cam: This white cam controls the drain. No adjustment is available.
#4 Cam: The H2O or fill cam opens the water solenoid. Too little water causes the pump to cavitate. Overfilling does not
allow all the water to drain between cycles, causing carry-over. Do not move the right side of the cam wheel. Adjust left-side
of cam wheel to close water solenoid when the dishmachine reaches full sprayarm pressure.
#5 Cam: This black cam controls sanitizer. The sanitizer cam is adjustable. Set sanitizer concentrations at 50 parts per
million (Warning: Do not exceed 100 PPM’s). Monitor chlorine levels by using chlorine test strips. To Test: Run rack of
dishes through a complete cycle, use test strip to test water sample from the top of any glass.
#6 Cam: This black cam controls rinse additive. The rinse-aid cam is adjustable.
#7 Cam: This cam is used to pause or “burp” the pump on the 3D-S, 5AG-S, 5CD, and L Series. It is set at the factory but
can be adjusted.
#8 Cam: Available on 2 1/2 minute timers only. Provides prewash/wash/rinse. Do not adjust.
Machine Tuning
Tuning is essential for proper cleaning
Do not skip this IMPORTANT PROCEDURE
The key to understanding proper tuning, is to realize that you cannot control or change the drain. It is a fixed function.
Therefore, all tuning is accomplished by setting or adjusting the fill cam in relationship to the fixed drain cam. The goal of
tuning is to eliminate all soiled water, through the drain, before the fixed drain closes.
A sign that soiled water has exited the tank will be the typical hollow sound of a pump running without water. It is at this
point that you want the water solenoid to come on. That function is controlled by the adjustment of the fill cam. For
optimum results, allow the fill water to flush the interior of the machine for a few seconds before the drain closes.
Once the drain is closed the fill cycle begins. Fill must continue until full spray arm pressure is reached. This can be
verified with the use of a spray arm pressure gauge attached to the lower wash arm end plug. This gauge will indicate
full spray arm pressure when the needle stops fluctuating and remains steady. Adjust your fill cam to turn the water
OFF when you reach this point of steady pressure. To satisfy code, a minimum of seven (7) seconds of full rinse pressure
(with chlorinated water) is required. Sanitizers should be injected during the second half of the fill cycle.
If a pressure gauge is not available, an approximation of full spray arm pressure could be determined by the sound of the
spray arms. There would be a typical continuous swishing sound of the water spraying. Again, this would be the point to
turn the water OFF.
Important Note: Seven seconds of full spray arm rinse pressure is required by code. In the event that air is trapped in
the pump during fill, a vapor lock can occur. If vapor locked, check incoming water temperature and reduce to 120 degrees
F. minimum (130-140 degrees F. recommended). If the problem is caused by low water pressure to the machine, see
plumbing instructions to correct condition. If vapor lock is still present, electrically stop or pause the pump to release air.
This is done by moving the brown wire on the back of the switch behind sanitizer cam. Move this brown wire, which is
currently on the top position of the switch, to the center position taking care that wires do not touch.
