 How to Get the Necessary Repair Components

BIUUUD19 (Published) Book specs- Dates: 20081231 / 20081231 / 20081231 Lang: ENG01 Applic: UUU

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

BIUUUK01 (Published) Book specs- Dates: 20130308 / 20130308 / 20130308 Lang: ENG01 Applic: PCR UUU

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.

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).

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.

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.

WC=Wiring Connector—A coupling device for joining two cables or connecting a cable to an
electronic circuit or piece of equipment. Connectors are male or female, according to whether
they plug into or receive the mating connector.

2. Component Terminal Numbering

CAUTION 1 : Risk of Mis-wiring—Due to electrical component manufacturing
inconsistencies, the pin numbers imprinted on components such as connectors and relay bases
used on Milnor machines often do not correspond to the pin numbers shown in the schematics.
• Ignore pin numbers imprinted on in-line connectors (e.g., Molex connectors) and relay
bases.
• Use the pin identification illustrations herein to identify pins on these components.

3. Features of Milnor® Electrical Schematic Diagrams

Document BMP010012 (following this section) is a sample schematic, based on a schematic
diagram for the Milnor® gas dryer. For the purposes of this exercise, the schematic is shown gray
and explanations of the items on the schematic are shown black.
The item numbers below correspond to the circled item numbers shown on the drawing.
1. The first six characters of the drawing number (W6DRYG) indicate that this is a wiring
diagram (W), identify the generation of controls (6), and identify the type of machine
(DRYG=Gas Dryer). These characters appear in the drawing number of every schematic in
the set.
The characters following the first six are unique to each drawing. The two characters
identified as the page number are an abbreviation for the function performed by the depicted

PELLERIN MILNOR CORPORATION

circuitry (S+=three-wire circuit) and establish the order in which the schematic occurs in the
manual (schematics are arranged in alpha-numeric order in the manual).
Whenever circuitry changes are significant enough to warrant publishing a new schematic
drawing, the new drawing number will be the same as the old except for the major revision
letter (A in the example).
2. Included in the drawing title are the class of control system, the title of this circuit, and the
circuit voltage.
3. Line numbers are provided along the bottom edge of the drawing. These permit service
personnel in the field and at the Milnor® factory to quickly relate circuit locations when
discussing troubleshooting over the phone. Page and line numbers are referenced on the
drawing as explained in items five and six below.
4. Relay contacts show the page and line number on which the relay coil may be found. This is
the type of cross referencing most frequently used in troubleshooting.
5. Relay coils show the page and line number on which its associated contacts are located.
6. Relay contacts and relay coils show the physical location of the relay.
7. The designation MTA applies to electronic circuit board connections. Typically, a control
system will contain several different types of circuit boards and one or more boards of each
type. A numerical suffix identifies the board type and a numerical prefix identifies which one
of several boards of a given type is being depicted. For example, the designation 1MTA5
identifies this as the first I/O board (8 output, 16 input board) in the control system. As shown
on the drawing, a pin number follows the board number, separated by a dash. Thus, 1MTA5-
9 is pin 9 on this board. The numerical designations for board types vary from one control
system to another. Some of the board types commonly encountered on the Mark V and Mark
VI washer-extractor control and their designations are as follows:
• MTM1-MTM8 = Mother board
• MTA1-MTA5 = 8 output, 16 input (8/16) boards
• MTA11-MTA14 = 24 output boards
• MTA30-MTA40 = processor boards
• MTA41-MTA43 = digital to analog (D/A) boards
• MTA51-MTA55 = analog to digital (A/D) boards
• MTA81-MTA85 = balance A-D board
The complete listing of the boards utilized in a given control system can be found in the
component list for that system.
8. Wire numbers, as described earlier in this section, are shown at appropriate locations on the
schematic drawing.
9. Where diamond symbols appear at the end of a conductor, these are match points for
continuing the schematic on another drawing. The page and line number that continues the
circuit is printed adjacent to the diamond symbol. Where more than one match point appears
on the referenced page, match diamonds containing corresponding letters.
