How to Get the Necessary Repair Components
This document uses Simplified Technical English.
Learn more at http://www.asd-ste100.org.
You can get components to repair your machine from the approved supplier where you got this
machine. Your supplier will usually have the necessary components in stock. You can also get
components from the Milnor®factory.
Tell the supplier the machine model and serial number and this data for each necessary component:
• The component number from this manual
• The component name if known
• The necessary quantity
• The necessary transportation requirements
• If the component is an electrical component, give the schematic number if known.
• If the component is a motor or an electrical control, give the nameplate data from the used
component.

How to Use Milnor®Electrical Schematic Diagrams

How to Use Milnor®Electrical Schematic Diagrams
Milnor®electrical schematic manuals contain a table of contents/component list and a set of
schematic drawings. These documents are cross referenced and must be used together.
The table of contents/components list shows, for every component on every schematic in the
manual, the component item number (explained in detail below), statement of function, parent
schematic number, part number, description and electric box location. In older manuals, two
component lists are provided: List 1 sorts the components by function, and List 2 by type of
component. Newer schematic manuals include only the list sorted by component number.
The schematic drawings use symbols for each electromechanical component, and indicate the
function of each. Integrated circuits are not shown, but the function of each microprocessor input
and output is stated. Certain electrical components not pertinent to circuit logic, such as wire
connectors, are not represented on the schematic.
Most machines require several schematics to describe the complete control system and all the
options available on the included models. In most manuals there are some schematic pages that
don't apply to your specific machine because certain options and configurations are mutually
exclusive or are not necessary in all markets. You may find it helpful to mark or remove such
pages. A schematic page that only applies to a subset of machines will normally state, in the title,
which models and/or options it covers. Compare this with the nameplate on your machine and
with your purchase records.
Each schematic is devoted to circuits with common functions (e.g., microprocessor inputs, motor
contactors). Schematics appear in the manual in alphanumeric order.
1. Component Prefix Classifications and Descriptions
Component item numbers consist of up to six characters and appear as part of a component's
symbol on the schematic. The first two characters indicate the general class of component, and
the remaining characters are a mnemonic for the function. For example, “CD” is the code for all
time delay relays, and “SR” stands for safety reset. Thus, CDSR is a time delay relay that serves
as a safety reset.
The following are descriptions of electrical components used in Milnor®machines. Descriptions
are in alphabetical order by the component class code (two character prefix).
Note 1: Some component class codes do not have a corresponding symbol, but are represented by a box
and an accompanying note describing the component. Examples of such codes are BA (printed circuit
board), ED (electronic display), and ES (electronic power supply).
BA=Printed Circuit Board—Insulating substrate on which a thin pattern of copper conductors
has been formed to connect discrete electronic components also mounted on the board.
CB=Circuit Breaker (Figure 1)—Automatic switch that opens an electric circuit in abnormal
current conditions (e.g., an overload).
Figure 1: Circuit Breaker (CB)
CD=Control, Time Delay Relay (Figure 2)—A relay whose contacts switch only after a fixed
or adjustable delay, once voltage has been applied to its coil. The contacts switch back to
normal (de-energized state) immediately when the voltage is removed.

CL=Control, Latch Relay (Figure 3)—A relay which latches in an energized or set position
when operated by one coil (the latch/set coil). The relay stays latched even though coil voltage
is removed. The relay releases or unlatches when voltage is applied to a second coil (the
unlatch/reset coil).

applied to its coil and revert to normal when the voltage is removed.

B. Contacts
CP=Control, Photo-Eye (Figure 5)—Photo-eyes sense the presence of an object without direct
physical contact. Photo-eyes consist of a transmitter, receiver, and output module. These
components may be housed in one assembly with the transmitter bouncing light off of a
reflector to the receiver, or these components can be housed in two separate assemblies with
the transmitter pointed directly at the receiver. The photo-eye can be set to turn on its output
either when the light beam becomes blocked (dark operate) or when it becomes un-blocked
(light operate).

CS=Control, Contactor/Motor Starter (Figure 6)—A relay capable of handling heavier
electrical loads, usually a motor.
Figure 6: Other Control Symbols
EB=Electric Buzzer (Figure 6)—An audible signaling device.
EC=Electric Clutch (Figure 6)—A clutch consists of a coil and a rotor. The rotor has two
separate rotating plates. These plates are free to rotate independent of each other until the coil
is energized. Once energized the two plates turn as one.
ED=Electronic Display—A visual presentation of data, such as an LCD (liquid crystal display),
LED (light emitting diode) display, or VFD (vacuum florescent display).
EF=Electric Fuse (Figure 6)—A fuse is an over-current safety device with a circuit opening
fusible member which is heated and severed by the passage of over-current through it.
EL=Electric Light (Figure 6)—Indicator lights may be either incandescent or fluorescent.
EM=Electro Magnet Solenoid—A device consisting of a core surrounded by a wire coil through
which an electric current is passed. While current is flowing, iron is attracted to the core (e.g.,
a pinch tube drain valve solenoid).
ES=Electronic Power Supply—A device that converts AC (alternating current) to filtered and
regulated DC (direct current). The input voltage to the power supply is usually 120 or 240
VAC. The output is +5, +12, and -12 VDC.
ET=Thermal Overload (Figure 7)—A safety device designed to protect a motor. A thermal
overload consists of an overload block, heaters, and an auxiliary contact. The auxiliary contact
is normally installed in a safety (three-wire) circuit that stops power to the motor contactor
coil when a motor overload occurs.

EX=Electrical Transformer (Figure 8)—A device that transfers electrical energy from one
isolated circuit to another, often raising or lowering the voltage in the process.
KB=Keyboard—Device similar to a typewriter for making entries to a computer.
MN=Electronic Monitor (CRT)—A cathode ray tube used for visual presentation of data.
MR=Motors (Figure 9)—Electromechanical device that converts electrical energy into
mechanical energy.
Figure 8: Transformer (EX) Figure 9: Electric Motor (MR)
MV=Motor (Variable Speed) Inverter—To vary the speed of an AC motor, the volts to
frequency ratio must be kept constant. The motor will overheat if this ratio is not maintained.
The motor variable speed inverter converts three phase AC to DC. The inverter then uses this
DC voltage to generate AC at the proper voltage and frequency for the commanded speed.
Note 2: Switch symbols used in the schematics and described below always depict the switch in its un-
actuated state.
PX=Proximity Switch (Figure 10)—A device which reacts to the proximity of an target without
physical contact or connection. The actuator or target causes a change in the inductance of the
proximity switch which causes the switch to operate. Proximity switches can be two-wire
(AC) or three-wire (DC) devices.

and/or closed by the mechanical action of a cam(s). Applications include 35-50 pound timer
operated machines, Autospot, timer reversing motor assembly, and some balancing systems.
SH=Switch, Hand Operated (Figure 12)—A switch that is manually operated (e.g., Start
button, Master switch, etc.).
Figure 11: Cam Switch (SC) Figure 12: Hand Operated Switch

SK=Switch, Key Lock (Figure 13)—A switch that requires a key to operate. This prevents
unauthorized personnel from gaining access to certain functions (e.g., the Program menu).
SL=Switch, Level Operated (Figure 14)—A switch connected to a float that causes the switch
to open and close as the level changes.
Figure 13: Key Switch (SK) Figure 14: Level Switch (SL)
SM=Switch, Mechanically Operated (Figure 15)—A switch that is mechanically operated by a
part of or the motion of the machine (e.g., door closed switch, tilt limit switches, etc.)
SP=Switch, Pressure Operated (Figure 16)—A switch in which a diaphragm presses against a
switch actuator.
