OPERATING INSTRUCTIONS
II. STANDARD CONTROLS
A.Modular Electrical Distribution System
The Tray-Trac has an electrical service
terminal box which is connected to the
main incoming electrical service. From
this point, power supply is provided to
each Modular Electrical Distribution
System [MR0E] running the length of each
side of the Tray-Trac. Each MR0E unit is
a linear panel board, with a main service
disconnect breaker, main system cable
bus and link plates containing a point-ofuse circuit breaker and either receptacle,
switch or internal connection. These link
plates can be moved to any location on
the system, or new plates can be added,
as long as the total kilowatt capacity
[ampacity] of each MR0E unit is not
exceeded.
B.Start/Stop Station
The unit is equipped with one or more pairs
of push buttons which are used to start and
stop the carousel motor. Depressing any of
the STOP buttons will stop the carousel
motor. These switches are intended to start
and stop the carousel at the beginning and
end of the serving period or whenever the
tray carriers will not be in use for an
extended period of time.
C.Speed Control
The unit is supplied with a variable speed
control unit located on the unload end
[inside
STOP/START Station, accessible through
the base cabinet door or access panel.
Trays must be timed manually and
adjustment made on the speed control dial.
See separate instructions for more detailed
information. Max speed of
minute.
III.ACCESSORIES AND CONTROLS
The following optional features may or may
not be supplied. Check drawing and
specifications to determine which features
are included in your systems.
A.Momentary Foot Stop Switch
The Tray-Trac is equipped with a two position
terminal within the Modular Distribution
the Tray-Trac] behind the
10 trays per
2
System at tray unload end. The optional
foot-operated momentary stop switch can be
mounted at this location. Depressing the foot
switch will cause the carousel motor to stop
and it will remain stopped as long as the
switch is depressed. When the operator’s
foot is removed, the carousel will begin
rotating again.
B.Fluorescent Work Lights
Fluorescent work lights may be supplied
beneath the carousel and/or under the
overshelf. The overshelf lights incorporate a
diffuser panel that is integral to the fixture to
reduce glare, protect the bulb an equalize
light distribution. The carousel work lights
use a separate prismatic clear plastic sheet
to protect the bulb and aid in light diffusion.
To replace the carousel bulb, slide the
diffuser panel upward in its slot, and allow the
back edge to drop down and out. The work
lights are operated by a switch that is usually
located alongside the carousel start/stop
switch. Power for the work lights is drawn
from one of the Modular Electrical
Distribution Systems. Three foot fixtures
require #F30-T8 Slimline Lamps, 18” fixtures
require #F15-T8 Slimline Lamps.
C.Hot Food Wells
Heavy-duty rectangular food wells can be
provided with or without drains. Wells are
able to accommodate a standard 12” x 20”
#200 pan up to six inches deep and are
suitable for either wet or dry operation. The
warming element is controlled by an infinite
switch control with a positive-OFF position.
Each food warmer has a separate control A
red signal light indicates a power-ON
condition. Add water to warmer BEFORE
preheating.
DRY, PRE-HEATED WARMER MAY
DAMAGE THE UNIT.
preheating, add hot water, place empty pan
in well, then cover well. Preheating varies
from 15-30 minutes.
NOTE: Hot food wells are warranted
directly by the manufacturer; refer to
separate warranty and owner’s
information.
Some hot food wells may be supplied with a
strainer and drain manifold. This manifold is
POURING WATER INTO A
For most efficient
equipped with a ¼ turn ball valve for flushing
and threaded caps at each end for easy
periodic rodding. At least 1” of water should
be in all wells prior to each meal assembly.
The most common method for putting water
into the hot food wells is to back feed through
the drain manifold. By closing the drain
manifold shut-off valve [located in the base
near the end doors] and filling one hot food
well, the water will back up into the other hot
food wells. Hot food wells without drains
must be filled individually and drained with a
cup and sponge.
D.Cold Tops and Cold Pans
Cold Tops [raised cooling surfaces] and Cold
Pans
available for full and half base Tray-Tracs.
The circuits for these items are protected by
breakers in the Modular Distribution Systems.
THESE BREAKERS SHOULD NOT BE
USED TO TURN THE UNITS ON AND OFF.
Switches have been provided beside each
breaker for turning these items on and off.
Units should be turned on approximately
thirty minutes prior to use and left on until the
end of the day.
NOTE: Cold tops and cold pans may or may
not frost, depending on humidity and ambient
atmospheric conditions.
The refrigerated surfaces are supplied with a
removable strainer and drain, which is routed
to one end of the Tray-Trac. This piping is
equipped with a 1/4-turn shut off valve for
flushing and threaded caps for periodic
rodding. To prevent back-up into drain
gutter, the drain should be flushed daily into
[recessed cooling surfaces] are
the open floor drain or bucket, and rodded
periodically.
E.Checker Audio Call System
To aid in communications between the
personnel, a Checker Audio Call Station can
be supplied. Power is supplied from a circuit
breaker connection plate in the Modular
Distribution Panel along the side of the unit.
To turn the system on, make sure that the
circuit breaker is on. Depress the ON/OFF
switch and the Power Indicator LED will
illuminate. If only one microphone is used,
adjust volume by turning the know labeled
“INPUT 1” until the desired level is obtained.
If two microphones are used, adjust the
volume of one microphone using the “INPUT
1” knob and adjust the volume of the second
microphone using the “INPUT 2” knob. The
“PROGRAM” knob is not used in Tray-Trac
applications. When the Checker Audio Call
Station will not be in use for an extended
period of time, turn the unit OFF using power
on/off switch.
After adjusting the amplifier, you are ready to
use the Checker Audio Call Station. To use
the system, hold the button on the side of the
microphone IN while speaking.
microphone is ON only while the button is
held IN.
microphone is mounted on an 18” long
adjustable, flexible gooseneck.
adjustments, consult the amplifier and
microphone operations manual.]
F.Timer Programmer [Seven Day, 24-Hour]
The timer programmer is used to
automatically control the ON/OFF of integral
and ancilliary equipment connected to the
Tray-Trac unit, especially heated bases.
Each Modular Electrical Distribution System
[MR0E] is connected separately thru a
bypass switch to the timer/programmer.
Either MR0E unit may be ON or OFF the
program. The timer/programmer and bypass
switches are located as shown on the
drawing. Refer to separate instructions for
programming.
