PREFACE SECTION 2
A Control center is a device used to start and stop a commercial disposer by the use of two push-button switches. It is commonly referred to as a control panel and contains various electrical component parts. The main functions of the control panel are to reverse the direction of the disposer motor each time it is started, start the water flow to the disposer, and allow it to flow for several minutes after the disposer is turned off.
This manual includes CC-101 series control centers manufactured since 1976 (i.e., CC-101 A through CC-101 G). Basic functions remained the same throughout the CC-101 series, but component parts changed, and eventually additional features were added.
NOTE Once the function and purpose of each component is learned, control centers manufactured before 1976 can also be diagnosed. If one studies the B and C models, the remaining models become easier to understand.
The model number of a control center can be found on the specifications decal located on the inside or outside of the enclosure door. All information on the decal (i.e., voltage, horsepower and phase) must be noted prior to diagnosing. Variations of a control center do not necessarily change the model number. Visual inspection will determine which wiring diagram in this manual applies to a given control center.
Factory assistance is available by calling 1-800-558-5700 (in Wisconsin call 1-800-922-2331).

GENERAL INFORMATION SECTION 3
GENERAL
This section is not intended as a complete installation guide. Basic notes and guidelines for installation are provided here for the purpose of checking or troubleshooting an existing installation. Detailed installation instructions were provided with the disposer; to obtain technical information not covered in those instructions, contact the Factory.
NOTE
Neither the IN-SINK-ERATOR Company nor any of its Authorized Service Centers performs original installations,
All installations are to be in accordance with local plumbing and electrical codes.
NOTE
The disposer control center must be mounted within direct sight of the disposer per local codes. Any remote control stations must also be located within direct sight of the disposer per local codes.
PLUMBING INSTALLATION
The following plumbing installation diagrams are included to illustrate the plumbing connections of a typical installation. Figure 5-1 shows an installation for a control center with an enclosure-mounted solenoid valve (models CC-101A and
CC-101B). Figure 5-2 shows an installation with a remote-
mount solenoid valve (all other models). The solenoid valve and flow control valve are each marked with arrows showing the proper water flow direction. Both valves must be installed so that the water flows through them in the correct direction or the valves will not work properly. Note that in all installations a syphon breaker (vacuum breaker) must be installed above the sink flood plane per local plumbing code.

WIRING DIAGRAMS SECTION 4
The standard disposer motor voltages are 115/208/230 volts for single phase electrical power and 208/230/460 volts for three phase electrical power.
NOTE
Three phase contactors require three sets of contacts to carry line voltage to the disposer, while single phase contactors require four Circuitry and parts function on all control centers are identified within their respective models. This applies to all component parts controlled by or on the secondary voltage side of the transformer, whether it is a 1 phase or 3 phase control center.
The wiring (circuitry) to the line voltage connections on the Reversing contactors are identical on all 3 phase (only) contactors. The wiring (circuitry) to the line voltage connections on the Reversing contactors are identical on all 1 phase (only) contactors.
sets. Two identical contactors are utilized in every control center to perform the function of reversing the disposer motor rotation.
Therefore, the wiring diagrams in this section (Figs. 4-12 through 4-
19) show 3 phase contactors but can be used to diagnose or trace circuitry for 1 phase or 3 phase control centers, keeping in mind that only the contactors are different from 1 phase to 3 phase. Refer to Figs. 4-10 and 4-11 for 1 phase contactor connections.
All electrical connections must conform to local codes. Be certain that all IN-SINK-ERATOR disposers and control centers are carefully and permanently grounded.
CAUTION
ELECTRICAL INSTALLATION
BEFORE ANY ELECTRICAL WORK IS PERFORMED, REMOVE LINE POWER FROM THE DISPOSER CONTROL CENTER BY TURNING OFF THE CIRCUIT BREAKER. USE A VOLTMETER OR CIRCUIT TESTER TO ENSURE THAT POWER IS OFF BEFORE PROCEEDING.
disposer motor voltage and phase must be the same as the electrical supply. Check name-plates on both units for ratings. All connections must conform to local codes. Ground the disposer control center, the disposer, and all control boxes.
The following wiring diagrams are included to illustrate the electrical connections for each standard model of disposer control center and disposer motor. For each standard model of disposer control center, wiring diagrams are shown to illustrate the most typical configura­tions. The wiring diagrams include motor connections. Since various options can be custom ordered for a control enter, the wiring diagrams for a particular model of control center do not reflect every possible option. Additional wiring diagrams illustrating various special (nonstandard) configurations of each model are provided in section 10 of this manual.

Figure 4-3. 115 V Transformer Taps.
CONTROL CENTERS WITH 115 V CONTROL CIRCUIT
Power lines carry line voltage to the primary terminals (also called "taps") of the transformer. Line L2 is connected to the common (ground) tap with Line L1 connected to the tap coinciding with the line voltage. The secondary taps on these transformers will always supply 115 V ac to the load. This secondary voltage operates the component parts in the control circuit. These transformers are rated at 100 VA (Volt/Amperes), and can be used for any 208 V/230 V/460 V incoming line. See Figure 4-3.
TRANSFORMER CONNECTIONS FOR CONTROL CENTERS WITH 24 V CONTROL CIRCUITS
All control centers with 24 V secondary voltage require one of two transformers. They appear identical. The specification decal on the transformers will show 120 - 240 V or 240 -480 V (connections for line voltage). There is no reference to 208 V, but it is to be understood that 208 V connections will be the same as 240 V. Whenever the recommended transformer is used wiring diagrams furnished with the Con­trol Center or in this manual apply.
Both 24 V secondary tap transformers can be used with 240 or 208 V inputs, but the terminal connections will change and Control Center wiring diagrams may not necessarily ap­ply. Whenever in doubt, refer to and use the connections shown on the transformer specification decal. Connections for input (primary) and output (secondary) voltages are the same in all cases. See Figure 4-4 for connections.

Terminal Connections
Transformer tap connections vary and are made in accor­dance with the applied line voltage. A conductive connec­tion strap is normally used but 12 ga. wire can be substituted (see Fig. 4-5).
Connections
Shown are the standard connections when the recommended transformer is used. Refer to the illustrated parts list for specific Control Centers. The voltage and phase of the Control Center must be known. Secondary voltage for Figs. 4-5 through 4-8 is 24 V.

SUBPANEL REMOVAL AND REPLACEMENT SECTION 6
GENERAL
This section provides the information required for the re­moval and replacement of the subpanel in the disposer control center enclosure. The subpanel is the flat piece of sheet metal inside the enclosure that most of the components are mounted on. Most components are secured with screws and can be changed without removing the subpanel. However, a few components are secured with screws to a nut on the back of the subpanel and require that the panel be removed to remove the component. Also, it is sometimes necessary to remove the subpanel to retrieve lost fasteners. Differences between control center models sometimes require slight differences in the procedures. The changes are described when necessary.

COMPONENT DESCRIPTION SECTION 7
GENERAL
This section provides information on the function of the component parts of the control center. Photographs of the individual components are provided, with a description ac­companying each one. For some components, more than one photograph is provided in order to illustrate minor component changes from one model to the next. This section also calls out the location of each component on the schematic diagram. Note that no one model of disposer control center contains all the components listed in this section. The components used in a particular control center can be determined by looking at the wiring diagram on the inside of the control center enclosure door.
Transformer
The transformer steps down the higher voltage from the power line to a relatively low 115 volts (24 volts for some models). This lower voltage is used for control purposes to power the controlling components, which may include a reverser/timer, a latch relay coil, a contactor coil, a solenoid valve, a solenoid valve timer, a restart delay timer, a timer relay coil, a control
circuit board, and an auto shutoff timer. Line voltage is applied to the primary winding (the top winding of the transformer as shown on the wiring diagram), and the control voltage (115 or 24 volts) is taken from the secondary winding (the bottom winding). The transformer has several different input connections so that it can be used with different line voltages.

. Fuse.
SECTION 7 COMPONENT DESCRIPTION (Cont'd)
Fuse
The fuse, designated F1 on the wiring diagrams in this manual, provides circuit protection in the event of a short circuit or other electrical problem in the control center. If too much current is used by the any component in the control center, the fuse will blow, opening the circuit. This fuse does not protect the disposer motor from excessive current; the disposer motor is protected by the circuit breaker or fuse in the line that supplies power to it or by the overload protector or the disposer motor.
On the wiring diagrams Inside the enclosure door, some models designate the fuse by Its F1 reference designation; other models designate It only by its fuse type, e.g. FNA 1 or FHA 2.
Door Interlock Switch (Line Disconnect)
NOTE
The door interlock switch is a safety device that combines a disconnect switch with a mechanical door latch. They are connected together by an "operating rod" that is fastened to the interlock switch. The door interlock switch must be turned off to open the control center door. Turning the switch off disconnects the power line from the disposer motor and from the transformer that supplies power to the control circuits in the control center. This is done as a safety precaution. However, line voltage is still present on the line terminals of the door interlock switch.
Figure 7-3. Door Interlock Switch.
7-2
Disconnect Switch
COMPONENT DESCRIPTION (Cont'd) SECTION 7
Control centers that do not have a door interlock switch have
one or two disconnect switches mounted at the top of the
control center enclosure. The switch (es) are positioned so that
when the control center door is closed, the switch plunger(s)
are pushed in, closing the switch contacts. Disconnect switch
contacts are wired in series. When the control center door is
opened, the switch contacts open and the control voltage is
turned off, either directly by the disconnect switch or indirectly
by a disconnect relay on units so equipped. This turns off line
voltage to the disposer control center (for units with two
disconnect switches, only one disconnect switch has to be
open to disconnect the control voltage). However, line voltage
is still present at the power line terminals of some components
(refer to the appropriate wiring diagram to determine which
terminals remain live for any particular model).
Disconnect Relay (Line Disconnect)
Some models of disposer control center have a disconnect
relay that works in conjunction with disconnect switches. The
disconnect relay supplies line power to the disposer control
center. The disconnect relay coil is powered directly from the
power lines (line voltage). Power to the disconnect relay coil is
controlled by the disconnect switches. If either switch opens
(the control center door is opened), the disconnect relay coil is
turned off. This opens the relay, disconnecting line power to the
disposer control center. However, line voltage is still present on
the power line terminals of the disconnect relay even when the
contactor is open.

START Switch.
SECTION 7 COMPONENT DESCRIPTION (Cont'd)
START Switch
The START switch has one or more sets of contacts, depending upon the model. When the START switch is pressed, all the contacts close. Depending upon the model, the contacts send power to different devices such as the contactor coil, the solenoid valve, the control circuit board, and the auto shutoff timer. All functions required to start the disposer are switched by the START switch contacts.
For all models, the START and STOP switches are each com­posed of a mechanical pushbutton connected to one or two detachable sets of electrical contacts that open and close as the pushbutton moves In and out. However, for the operational description, the STOP and START switches are treated as single components rather than as assemblies.
STOP Switch
The STOP switch has one or more sets of contacts, depending upon the model. When the STOP switch is pressed the contacts open or close, depending upon whether they are normally open. or normally closed. One set of contacts opens to interrupt power to the contactor coil (either directly or via the control circuit board). Other contacts close to activate the alternator/timer, latch relay, or the restart delay timer.
NOTE
NOTE
The start and stop switches are momentary contact pushbut­ton switches. Once pressed in, they will return to their original position when released.
Figure 7-7. STOP Switch.
7-4
Remote Control Station
Figure
7-8.
Remote Control Station.
COMPONENT DESCRIPTION (Cont'd) SECTION 7
This is a START switch and a STOP switch that can be mounted at a distance from the control center, and are the same type and design of those on the control center. The remote START switch contacts are connected in parallel with the control center START switch contacts. The remote STOP switch contacts are connected in series or parallel with the control center STOP switch contacts, depending upon the model. (Refer to the appropriate wiring diagram.)
Pressure Switch
The pressure switch prevents the disposer motor from operating if the water pressure falls below approximately 15 p.s.i. If pressure drops below this point, the pressure switch opens, interrupting power to the component parts and shuts down the disposer. The START switch must be pressed to restart the disposer. The pressure switch acts in the same manner as a STOP switch.
Figure 7-9. Pressure Switch.
7-5
Reverser/Timer
SECTION 7 COMPONENT DESCRIPTION (Cont'd)
The reverser/timer performs two different functions for the disposer control center. It switches between the F and the R contactor coils with every START/STOP cycle. This provides the automatic reversing action for the disposer motor. It also controls the water flow timing cycle. When the STOP switch is pressed the reverser/timer begins the 5-minute water flow timing cycle; it maintains power to the solenoid valve until the cycle ends. Terminal 2 is the power input, terminal 7 is ground (common), terminal 4 is the output that drives the solenoid valve, and terminal 3 senses when each START/ STOP cycle begins and ends. Terminals 6 and 8 connect to the F (forward) and R (reverse) contactor coils respectively. Note that when the START switch is pressed, the reverser/ timer connects the F or R contactor coil internally to pin 7 to turn the contactor coil on.
Latch Relay (Reversing Relay)
The latch relay performs the automatic reversing of the dis­poser motor. This relay toggles ("flip-flops") or switches between its two sets of contacts once per START/STOP cycle. In one position, the latch relay directs voltage to the F (forward) contactor coil, causing the disposer motor to run in the forward direction. In the other position, the latch relay directs voltage to the R (reverse) contactor coil, causing the motor to run in the
Figure 7-10. Reverser/Timer and Socket.
reverse direction. The latch relay changes position every time the STOP switch is pressed.
Figure 7-11. Latch Relay.
7-6
COMPONENT DESCRIPTION (Cont'd) SECTION 7
Alternator Switch (Reversing)
The alternator switch provides auto-reversing action for the disposer motor by alternately selecting between its two out­puts every START/STOP cycle. The alternator switch is me­chanically linked with the STOP switch so that every time the STOP switch is pressed, the alternator switch changes from one output to the other. One output is connected to the F contactor coil; the other is connected to the R contactor coil.
Contactors (Reversing Contactors)
Two contactors, F (forward) and R (reverse), direct line voltage to the disposer motor. They are either mounted sep­arately or on a mutual mounting plate. One connects the disposer motor windings to run the disposer in the forward direction. The other connects them to run in the reverse di­rection. Depending upon the model of disposer control center, selection of the contactors is controlled by the reverser/ timer, reversing switch, latch relay, or control circuit board. This description does not include the auxiliary contacts or auxiliary contact microswitches mounted to the reversing contactor. When power is applied to one of the contactor coils, all of the contacts associated with that coil close. They open again when power is removed from the coil. Note that only one contactor, F or R, can be energized at a time. All the F contacts shown on the wiring diagram close when the F con­tactor coil is energized. All the R contacts close when the R coil is energized. When the contactor pulls down engaging the contacts carrying power to the motor, it also activates the auxiliary contacts or auxiliary contact microswitches.
Since the application of the contacts differs from one model of disposer control center to the next, it is necessary to refer to the wiring diagram for each model to determine their functions.

STOP switch).

Auxiliary Contacts.
Auxiliary Contacts
SECTION 7 COMPONENT DESCRIPTION (Cont'd)
Auxiliary contacts are additional sets of contacts (block or microswitches) mounted to and are activated in unison with the mechanical action of the reversing contactors.
Auxiliary contact blocks are mounted to the end of the reversing contactor. See Fig. 7-14 (A).
Auxiliary contact microswitches are mounted to the top of the reversing contactor. See Fig. 7-14 (B).
Auxiliary contacts may contain one or two sets of contacts which may have any combination of N.O. and/or N.C.
They are used in the control circuit to:
• Bypass the start button (switch) after the unit is started and the start
button is released, maintaining power to the control circuit.
• Activate power to the "F" or "R" coil in the reversing contactor.
• Engage the time delay relay controlling the solenoid valve.
• "Lockout" the reversing contactor coil not engaged preventing it
from being activated.
• Maintain power to the time delay relay holding the solenoid valve
engaged after the stop button is pressed and the disposer motor stops.
The model of the control center determines the type, the number of and the function of the auxiliary contacts. Review the respective wiring diagram.
Solenoid Valve
The solenoid valve is an electrically-controlled water valve. The valve opens when power is applied to the solenoid valve coil, allowing water to flow to the disposer. When power to the coil is removed, the valve shuts off the water flow. The solenoid valve is powered by the transformer in the disposer control center, and is controlled by the reverser/timer, the time delay relay, or a printed circuit board.
The solenoid valve must be installed with its arrow pointing downstream or erratic water flow will occur.

The solenoid valve timer is a solid state electronic device. After the STOP switch is pressed the disposer motor stops but, the solenoid valve timer supplies power to the solenoid valve for a defined time (which can be adjusted by a poten­tiometer) to provide water to the disposer which helps reduce drain clogging. When the water flow timing cycle ends, the solenoid valve timer removes power from the solenoid valve, shutting off the flow of water.
Potentiometer
The potentiometer is a device with an adjustable screw or stem used to control the time-out of the time delay relay. It is connected directly to the time delay relay and is adjustable from 0 to 5 or 10 minutes depending on the model. Using a small flat blade screwdriver and turning the screw fully clockwise, will set the time-out to maximum.
Restart Delay Timer
The disposer motor should not be subjected to rapid reversals in direction which could occur if the unit were turned on and off rapidly a number of times, which causes' motor burnout. To prevent this, the restart delay timer stops the disposer from restarting within 5 seconds after it is turned off. The restart delay timer is a non-adjustable electronic timer. When the STOP switch is pressed, one pair of STOP switch contacts (as shown on the wiring diagram) signals the restart delay timer to begin the restart timeout period. When this happens, the restart delay timer applies power to the timer relay coil. The timer relay contacts open, preventing power from reaching either contactor; this prevents the unit from being started. When the restart timeout period ends, the restart delay timer allows normal operation again.

SECTION 7 COMPONENT DESCRIPTION (Cont'd)
Timer Relay
This time relay has several sets of contacts which can N.O., N.C., or both. The contacts open or close when the coil in the relay is activated.
This relay works in conjunction with the restart delay timer to provide restart delay protection control for the disposer motor. When the STOP switch is pressed, the bottom STOP switch contacts close, supplying power to the restart delay timer and the timer relay coil (TR). The energized coil closes the TR1 contacts, supplying power to terminal 2 of the restart delay timer. This signals the restart delay timer to maintain power to the timer relay coil (via terminal 1) until the restart timeout period expires. During the restart timeout period, the TR2 contacts open to prevent current from flowing through the reversing contactor coils, thus preventing operation of the disposer motor. When the restart timeout period expires, the restart delay timer removes the power from terminal 1. The TR relay then returns to normal, opening the TR1 contacts and closing the TR2 contacts. When this happens, the disposer can be started again.

Control Circuit Board.
COMPONENT DESCRIPTION (Cont'd) SECTION 7
NOTE This electronic circuit board contains the larger and bulkier time delay relays, relays potentiometer and alternator found is earlier model control centers. It is a totally self-contained unit and is non-repairable.
This device controls the reversing contactor coils, the water flow tinning cycle, the restart timeout period, and the auto shutoff function for the control center. It also controls the auto reversing for the disposer motor with every START/ STOP cycle. Power from the transformer is supplied to the circuit board via terminals 2 and 4. Terminal 4 is the common, or chassis ground. Terminal 7 of the control circuit board is the START/ STOP switching input. When the input goes high (on), the control circuit board starts the disposer motor and turns on the solenoid valve to allow water to flow to the disposer. When the input goes low (off), the control board stops the disposer, begins the water flow timing cycle and begins the restart timeout period. Terminal 11 is the output line to the F (forward) contactor coil. (Power is supplied to the F contactor coil via terminal 11 and chassis ground, terminal 4.) This line is used to close the F contactor, which runs the disposer motor in the forward direction. Terminal 12 is the output line to the R (reverse) contactor coil. (Power is supplied to the R contactor coil via terminal 12 and chassis ground, terminal 4.) This line is used to close the R contactor, which runs the disposer motor in the reverse direction. Terminal 13 is the output line to the solenoid valve. (Power is supplied to the solenoid valve via terminal 13 and chassis ground, terminal 4.) This line is used to turn on the solenoid valve, which allows water to flow to the disposer.
Flow Control Valve
The flow control valve is installed in the water supply line between the solenoid valve and the disposer. When the so­lenoid valve is open, the flow control valve regulates the flow of water to the disposer. By providing optimum water flow, it prevents excessive water consumption while allowing adequate water for proper disposer operation. The flow control valve requires no electric power. Disposer application requires a properly sized valve (3,5 or 10 G.P.M.) 3/4" N.P.T. It must be installed with the arrow on the valve pointing downstream or the diaphragm in the valve will not control proper water flow.

SECTION 7 COMPONENT DESCRIPTION (Cont'd)
Auto Shutoff Timer
The auto shutoff timer is an adjustable electronic device that is electrically the same as the solenoid valve timer. The auto shutoff timer is connected so that once the disposer motor is started, it will shut off automatically after a defined period of time (the period may or may not be adjusted by a poten­tiometer). However, the motor will also stop at any time if the STOP switch is pressed.

COMPONENT DESCRIPTION (Cont'd) SECTION 7
Pressure Switch
A pressure switch is an electrical switch whose contacts are activated by water pressure.
A water line connected to the water fitting allows water pressure to press against a diaphragm. This action overcomes the spring tensioned disk behind the diaphragm, allowing the disk to make and activate the switch contacts.
The pressure switch assures water flow to the disposer when it is running. Whenever the water pressure diminishes, it is sensed by the pressure switch and its contacts open shutting down the operation.
Pressure switches in control centers are preadjusted to close its contacts at a water pressure of 15 P.S.I, or more.
A momentary pressure drop can cause the switch to drop out, opening the circuit.

OPERATING SEQUENCE SECTION 9
GENERAL
This section describes the operating sequence of the IN-SINK­ERATOR Commercial Disposer Control Center and illustrates the electrical operation with diagrams. The description is written to apply to all control centers, with differences between models noted as necessary. Differences between models are best noted by referring to the schematic wiring diagrams that are mounted on the inside of the door in each control center enclosure.
NOTE All models have some type of interlock or disconnect switch that prevents operation of the disposer when the control cen­ter door is open.
1. The operator presses the START switch. The START switch contacts close, supplying power to the F (forward) or R (reverse) contactor coil. On some models, the power does not go directly to the contactor coils from the switch, but instead goes to a control circuit board that determines which contactor coil will be energized. Some models have a second set of contacts on the START switch that supply power to the solenoid valve while the start switch is pressed. When the START switch is released, power to the solenoid valve is supplied by the reverser/ timer, the solenoid valve timer, or the control circuit board, depending upon the model. Models equipped with an auto shutoff timer have an additional pair of contacts on the START switch that signal the auto shutoff timer to begin timing the auto shutoff cycle. (On all models the disposer motor stops immediately when the STOP switch is pressed, regardless of whether the unit has an auto shutoff timer.)
NOTE
For models that have a pressure switch, the water pressure must be at least 15 p.s.i. to keep the pressure switch closed or the disposer motor will not run. If the water pressure Is less than 15 p.s.i. the pressure switch contacts will open, pre­venting power from reaching the contactor coil.
NOTE For the purpose of this description, operation is described with the F contactor coil selected. However, operation Is the same when the R coil is selected; the only thing that changes is the disposer motor's direction of rotation. (The direction reverses with every START/STOP cycle.) Energizing the F contactor coil closes all the F contacts shown on the wiring diagram. Energizing the R contactor coil closes all the R contacts. Only one contactor can be closed at a time.
2. The energized contactor coil closes the contactor, causing two things to happen:
a. Power is applied to the disposer motor through the F
contacts.
b. The F contact across the START switch closes, sup-
plying continuous power to the contactor coil. This keeps the contactor closed after the START switch is released. (This has the same effect as holding the START switch in continuously.)
9-1
SECTION 9 OPERATING SEQUENCE (Cont'd)
3. Solenoid valve power is maintained by the reverser/ timer, the solenoid valve timer, or the control circuit board, depending on the control center model.
This condition continues until the operator presses the STOP switch.
4. The operator presses the STOP switch. The STOP switch contacts open, interrupting power to the F contactor coil.
Some models have a second set of contacts on the STOP switch that are used to supply power to the latch relay coil to make it change from one state to another, or to signal a restart delay timer to begin the restart timeout period. On some models a reverser switch is mechanically linked to the STOP switch. The reverser switch is used to alternately select the F (forward) or R (reverse) contactor coil, which determines the disposer motor's direction of rotation. The two output terminals of the reverser switch are connected to the F and R contactor coils. Every time the STOP switch is pressed, the reverser switch changes from one output terminal to the other. Models with a restart delay timer have an additional set of contacts on the stop switch that signal the restart delay timer to begin the restart timeout period.
5. The F contactor coil releases (opens) the F contacts, turning off power to the disposer motor.
6. The water flow timing cycle begins. During the water flow timing cycle, solenoid valve power is maintained by the reverser/timer, the solenoid valve timer, or the control circuit board, depending on the control center model.
7. When the water flow timing cycle ends, the reverser/ timer, the solenoid valve timer, or the control circuit board removes power from the solenoid valve, shutting off the flow of water to the disposer.
8. Operation is the same for the next START/STOP cycle, except that the R contactor is energized instead of the F contactor.
REVERSING
All CC-101 Series Commercial Disposer Control Centers perform automatic reversing of the disposer motor with each START/STOP cycle. The disposer operates effectively in either direction, and the reversing action doubles the life of the shredders in the disposer. The reversing can be accomplished with a reverser/timer, a latch relay, an reverser switch, or a control circuit board, depending on the control center model. Although the components are different, they all perform disposer motor reversing by changing state every START/STOP cycle. Descriptions of these components are provided in the Component Function section of this manual.

COMPONENT TESTING AND REPLACEMENT SECTION 10
GENERAL
This section provides information on testing and replacement of all the disposer control center components, including the solenoid valve and the pressure switch. Component variations among the different disposer control center models are noted in the procedures when applicable. To simplify testing, these procedures test the components in the circuit whenever possible. This eliminates having to remove each component for testing.
Many of the test procedures require a voltmeter. Either a volt-ohm meter (VOM), a digital multimeter (DMM), or a vacuum-tube voltmeter (VTVM) may be used. All measurements are in AC volts unless otherwise noted. Continuity testing (with ohm meter) can be used - with line voltage off - to test components. Care must be taken to set the meter to the correct setting (voltage or ohms) and range BEFORE each measurement is taken. Failure to do so may destroy the meter. (The expected voltage or resistance reading is listed in each step where a voltage measurement is taken.) Also, be sure to plug the meter test leads into their correct sockets on the meter; on many meters, the lead sockets used for resistance measurements are separate from the sockets used for voltage measurements.
WARNING
TESTING OF COMPONENTS IN THE CIRCUIT WITH POWER APPLIED EXPOSES THE REPAIR TECHNICIAN TO DANGEROUS VOLTAGES. BE VERY CAREFUL NOT TO TOUCH ANY WIRES OR TERMINALS THAT MAY BE CARRYING HIGH VOLTAGE.
Each wire in the disposer control center is identified by a numbered tag on the wire. (Red wires carry control voltage, black wires carry line voltage.) The same numbers are shown on the wiring diagram. Component terminal numbers provided in this section, unless otherwise noted, refer to the identification number of the wire connecting to a component terminal.
Many tests require that the door interlock switch or disconnect switch (es) be defeated. Appropriate defeat procedures are provided at the beginning of this section.

INFORMATIONAL TIPS
SECTION
12
• Before making any repairs, find out if someone else has
attempted to fix the problem, and find out what has al­ready been done or attempted.
• When the enclosure door is open(ed), some components
may still be "live". Line voltage will be present until the main circuit panel or disconnect is turned off. Once the line voltage is off, check the control center components with a voltmeter to ensure that no voltage is present.
• A standard neon test lamp can be modified for use as a
safety light to warn if the power line has been reener­gized (see Figure 12-1). It can be attached to the line side of the reversing contactor inside the enclosure while service is being performed. If the lamp lights, power has been turned on.
• Replaced control centers are good reference/study tools.
Studying them just before making service calls should help diagnosis even though the specific models may vary somewhat in configuration.
• Whenever power must be on in the enclosure during
control center diagnosis, use a 12 inch long, 1/8 inch diameter dowel for "picking and pushing" at the com­ponents. DO NOT USE METAL TOOLS FOR PROBING INSIDE A LIVE CONTROL CENTER ENCLOSURE.
• The area around disposer control centers are very prone
to be wet — sometimes under water. Do not stand on wet floors or equipment when working on any electrical equipment.
• Bypassing the control center and running the disposer
direct using a "cheater cord" will help to isolate the problem in either the disposer or the control center.
• Low or unstable line voltage at the transformer has a
definite effect on the secondary transformer output. Al­ways check the primary and secondary voltage at the transformer, especially when erratic or "phantom" problems are present. Low secondary voltage can cause inoperable component parts.
Figure 12-1. Modified Neon Test Lamp.
Cut probes from both test lamp wires and fasten needlepoint alligator clamps. One test lamp must be made for every voltage - 115V, 208/230 V, 460 V. Ensure that line power Is off before connecting test lamp.
• Although a wiring diagram may show only one wire at a
terminal, there may actually be more. Wiring diagrams are drawn for electrical circuit clarity and accuracy, not complete physical accuracy. Any time a wire is removed, it should be marked if the service technician must leave the site.
• Do not remove wires or components requiring replace-
ment (unless absolutely necessary) until the replacement part is in hand.
Next Page
12-1
SECTION 12 INFORMATIONAL TIPS (Cont'd)
• If temporary repairs must be made to the control center or disposer to make the disposer operate until replacement parts can be obtained, make sketches for reference. MAKE CERTAIN THAT TEMPORARY REPAIRS ALLOW SAFE OPERATION OF THE DISPOSER AND CONTROL CENTER, AND THAT THE TEMPORARY REPAIRS DO NOT DAMAGE OTHER COMPONENTS.
• Solenoid valves furnished with control centers have a single voltage coil. Solenoid valves with proper multi­voltage coils can be used providing the coil wires are connected to accept secondary voltage from the control centers.
• Solenoid valves mounted on older control center models can be relocated elsewhere if required. Rewiring and enclosure protection must be in accordance with local electrical codes.
• A few control centers made for specific requirements have additional components or different configurations than are shown in this manual. Contact the factory for assistance if needed.
• Access holes for control center power supply lines are to be sealed and watertight. If water is found inside the control center enclosure, notify the owner/management of the site.
• Some control centers may be subjected to vibration, jarring and pounding due to their location and the work habits of kitchen personnel. This could result in wiring connections and component mounts working loose. Before leaving each job, check all wiring connections (spade, screw and solder) and mounting means (screw, nut and bolt) to ensure that all connections and components in the enclosure are tight.
• Follow these steps first when diagnosing control centers and make observations.
1. Attempt starting the unit.
2. Shut off power at control center (turn handle or open door).

SPECIAL EQUIPMENT SECTION 13
GENERAL
Special, or non-standard control centers account for only a small portion of all control centers. This section provides an overview of special control centers.
ADDED PARTS
The most common difference between a special control center and a standard control center is that the special control center has an added auto shutoff timer to provide an automatic shutoff feature. The auto shutoff feature turns off the disposer automatically after a set amount of time. Auto shutoff is standard in control centers with PC boards. A few control centers are non-standard because they have been equipped with a non-standard input voltage transformer (e.g. 415 volts, 380 volts, etc.). Sometimes a control center may appear non-standard, but a visual inspection will reveal that it is a standard control center that has been incorrectly modified by a repair person.
REMOTE PARTS
The addition of a remote control station also makes a control center special.
REPAIR PARTS
If the part(s) required to make a repair are not found on the appropriate parts sheet, contact the factory for assistance. The specification decal shows an engineering serial number (i.e. ENG 12935 AM) used for identification of special equip­ment.

GLOSSARY OF TERMS SECTION 14
NOTE
Many of the components listed in this glossary apply only to specific models of the control center. Alternator Switch: A switch that alternately selects the foward or reverse direction of rotation for the disposer motor. The switch is mechanically coupled to the stopswitch. Alternator/timer: An electronic module that controls the so­lenoid valve timing and alternately selects the forward or re­verse direction of rotation for the disposer motor. Auto Shutoff Timer: An electronic timer that automatically turns off the disposer motor after a preset amount of time. Auxiliary Contacts: Contacts that are supplementary to the main contacts and are actuated at the same time. Carbon Tracking: Traces of carbon oxidation usually depos­ited on contacts as a result of arcing. Cheater Cord: A short electrical cord, designed to be plugged into a standard receptacle, used to supply power to the disposer motor to determine if a problem lies in the disposer or in the control panel. Coils: A long conductor (or group of conductors) wound into a tight package to take advantage of the resulting inductance. Contact Blocks: A block of conducting material used in a relay or contactor to close a circuit. Contactor: An electromechanical switching device that allows the low-power control voltage circuit to turn the disposer motor on and off. Control Circuit Board: A printed circuit board that controls the solenoid valve timing and auto shutoff timing, and alter­nately selects the forward or reverse direction of rotation for the disposer motor. Control Circuits: The control circuits include the printed cir­cuit board, start and stop switches, disconnect or door in­terlock switch, pressure switch, all relay and contactor coils, all timers, and the solenoid valve. Control Voltage: The control voltage is 24 volts ac or 115 volts ac, depending upon the model of disposer control center. All control circuits in the disposer control center are powered by the control voltage. This provides a margin of safety by isolating the operator from the higher line voltage that powers the disposer motor. Disconnect Relay: A relay that connects the line voltage to the rest of the control center when line voltage is applied to the relay coil. The relay coil is controlled by a disconnect switch. Disconnect Switch: A plunger switch that opens a control voltage circuit, either directly or via a control relay, when the enclosure door is opened. The plunger is pushed in, closing the circuit, when the door is closed. Door Interlock Switch: A manually-operated rotary switch that disconnects line power from the disposer control center when the enclosure door is opened. The door cannot be opened without turning the switch off.

NOTE
The application of this technical brochure is based on the Model CC-101G Control Panel, but is also applicable to the Model CC-101H. The line disconnect switch on the Model CC-101H Is a rotary switch controlled by an ON/OFF knob on the control center cabinet. It Is located In the electrical circuit prior to any and all components. Component parts of the Model CC-101H have been reposltioned on the subpanel. Wiring diagrams and sequence of operations remain the same and can be used for either model.

INTRODUCTION OPERATION
A. Disposer motor wiring connections are made to
terminal blocks in the Control Center in ac­cordance with diagram furnished with the Control Center.
B. Transformer primary terminals are prewired at
the factory for the line voltage to be used. Specification decal (voltage) of the Control Center and of the disposer must match the line voltage.
C. Component parts wired to the secondary side
of the transformer work on secondary voltage. Notice the F and R coils; they are actually located in the F and R sides of the reversing contactors. Although the reversing contactors carry line voltage to the disposer motor, the coils work on secondary voltage.
D. The reversing contactors are actually two
separate magnetic contactors. Only one con­tactor is actuated at a time depending on which contactor coil is actuated, (F or R). This determines the direction of the motor rotation (forward or reverse).
E. The four auxiliary contact blocks are mounted
to the reversing contactors. Aux 1 F and Aux R are screwed to the end of the F contactor. Aux 2 R and Aux F are screwed to the end of the R contactor. They are actuated only when that contactor is actuated. Aux 1 F or Aux 2 R hold the circuit closed after the start button is pressed in and released. Aux R and Aux F act as an electrical lockout when one contactor is engaged. The electrical lockout prevents any electrical power to the other contactor thereby preventing dead shorts and equipment burnout.
F. The door interlock switch will shut off only the
secondary voltage when the door is opened. It does not shut off the line voltage. The line side of the transformer and the reversing contactors remain hot.
The power supply, motor lead wires and

The power supply is turned on at the elec-
trical panel, enters the primary side of the transformer and is stepped down to 24 volts at the secondary-side (terminals).
There is now power to the printed circuit
board. Closed circuit is from the trans­former through the door interlock switch and fuse and enters the printed circuit board at Terminal 2. The power exits Ter­minal 4 and returns to the transformer completing the circuit. All other circuits remain open. The "Power" light on the P.C. board is glowing indicating readiness mode. Everything else is idle.
There is also power through the stop (N.C.)

There is no power at Terminal 12; therefore, the R contactor and coil circuit are not affected.

power to the solenoid valve coil; OR If plug-in pin is in "Auto" position, a second time
delay will interrupt power to the contactor coil after approximately ten minutes run and allow the contactor to open. Water flow will time out and stop. The stop switch will override the "Auto" mode and will stop the disposer anytime.
Once the disposer is stopped (for at least ten
seconds), the alternator (a) in the P.C. board will disengage Terminal 11 and engage Terminal 12. Now, when the unit is next started, power will be directed to R coil and the R contactor will engage carrying line voltage to the disposer causing it to run in the R (reverse) direction. In this mode, now Aux 2 R and Aux R are in play. The R light glows. The F light does not.
Once the disposer is stopped, there no longer is
incoming power at Terminal 7 at the P.C. board. The incoming power at Terminal 2 now operates the power to the solenoid coil.
Every time the unit is restarted after a 10
second delay, the "a" (alternator) will alternate its position from Terminal 11 (F) to Terminal 12 (R) causing the disposer motor to run opposite its previous direction. If the disposer is restarted without a 10 second delay, the disposer will run in the same (previous) direction.
