3. Conveyor Start Switch
A conveyor may be equipped with a green Start switch that is located
remote to the Conveyor Control Panel. A conveyor may have more than
one Start switch. Pressing any Start switch will cause the conveyor belt
to go into motion.
4. Momentary Switch
Some conveyors may be equipped with a momentary contact conveyor
run switch, remote of the conveyor control panel. If the conveyor is off,
pressing the black Momentary Switch will cause the conveyor to run for
as long as the switch is held in. If the conveyor is running, it will continue
to run for as long as the black, Momentary Switch is depressed, then
stop as soon as it is released.
D. End Switches (Optional)
1. Limit Switch
A limit switch may be provided with the conveyor. When activated,
the limit switch will momentarily stop the conveyor. The conveyor will
continue to run as soon as the obstruction is removed.
a. Photocell Beam Type
The photocell, beam type switch uses a polarized, reflected beam
of light to determine when an object has reached the end of the
conveyor. When the beam of light is interrupted, the conveyor stops.
When the obstruction is removed, the conveyor continues.
b. Arm Switch Type
A flexible, movable arm actuator attached to an electrical switch
may be mounted in the back-splash of the conveyor bed. When an
object moves the arm, the conveyor stops momentarily. When the
object is removed, the conveyor continues to run.
c. Pressure Type
A flat plate located at the end of the of the belt is attached to an
electrical switch mounted at the end of the conveyor bed on the tank.
When an object moves the plate, the conveyor stops momentarily.
When the object is removed, the conveyor continues to run.
2. Anti-Jam Switch
The conveyor may be equipped with a flip-up anti-jam cover plate
mounted at the drive end. When an object becomes wedged between
the belt and the cover plate, the cover plate pivots up and causes the
conveyor belt to stop. The conveyor will not restart until the anti-jam
cover plate is returned to its normal running position and the Start
switch is pressed. A magnet is provided inside the anti-jam cover plate
to catch flatware before it falls into the drive compartment.
E. Motor Control Adjustments

MAINTENANCE
WARNING: DO NOT USE STEEL WOOL OR ANY OTHER ABRASIVE PAD ON THE
CONVEYOR SURFACE.
WARNING: DO NOT SPRAY THE CONVEYOR CONTROLS DIRECTLY WITH A HOSE.
WARNING: DO NOT OPERATE CONVEYOR WHEN DRIP PAN IS IN THE DOWN POSITION.
A. Cleaning
It is important that the AVTEC conveyor is kept clean in order to avoid
unsanitary conditions. It has been designed with ease of cleaning in mind. It
is recommended that the electrical power to the conveyor be turned off or
disconnected while being cleaned.
1. Drip Pan - for Hinge Type Belt
Standard drip pans are accessible from the side of the conveyor and
should be routinely cleaned. Note: DO NOT operate conveyor when drip
pan is in the down position.
2. Drip Pan for Chain Type Belt
These drain pans are located about 1/4" from the return belt. If provided
with the flush feature, they need not be cleaned under normal operating
conditions. The drip pan may be lowered for cleaning or replacing the
belt.
To lower the drip pan:
Holding the drip pan with hand to relieve the pressure, release the catch
by sliding the lock upwards, as shown, allowing the latching bracket to
rotate down.
To return drip pan to upper position:
Holding the drip pan in upper position, rotate the latching bracket to the
upper position, latching bracket will self-lock [See fig. 5.1].
3. External Scrap Basket (Tank)
Conveyors equipped with the optional belt wash/flush have a scrap
basket to prevent drain blockage. This scrap basket requires periodic
removal to empty its contents. The basket is located externally at the
base of the tank. [See fig. 5.2].
