Putting too much linen into a properly designed laundry washer-extractor will not overload
the machine to its mechanical or electrical detriment if these guidelines are followed:
1. The goods consist of typical cotton and/or synthetic fabrics normally encountered in
commercial laundering operations.
2. The load is not so bulky as to prevent a reasonably balanced distribution prior to the onset of
extraction.
3. The extract speed has not been increased above the designed maximum.
4. The total number of intermediate and final extractions do not exceed the designed maximum
for the extract motor.
Thus, the maximum soiled linen capacity for any properly designed washer-extractor is
essentially limited by the amount of soiled goods that can actually be placed in the cylinder.
The maximum weight of soiled goods that a washer-extractor cylinder will accept depends
on the following factors:
• the internal volume of the cylinder (the space into which the goods can be placed), and
• the density (weight and bulkiness) of the specific goods
For example, many polyester-cotton fabrics have relatively low weights for their bulk so one
should rarely expect to be able to put in a published maximum capacity load of such fabrics. In
fact, published maximum capacities of machines based on the now generally accepted industry
standards will usually be achieved only with the highest density, closely woven fabrics and a
reasonable soil content.
The best load size depends on the size of the machine—plus the type of goods, soil content,
and wash quality desired. Since the latter factors vary considerably, prior experience and/or
experimentation generally yield the best results. Use these guidelines:
1. Overloading a washer-extractor will not increase production because longer wash formulas
and more rewash will be required.
2. Avoid underloads because the inevitable greater extraction imbalance will cause more extract
re-cycles and may stress the machine unnecessarily.
3. Load divided cylinder machines so that the weight in each compartment is approximately
equal at the onset of extraction. Do not put goods with grossly dissimilar water absorption
characteristics in the different compartments. Do not attempt to balance loads of wet goods in
one compartment against dry goods in the other.

Many pumped liquid chemical systems dribble concentrated chemicals out of the injection
tubes when the system is not used for relatively long periods of time—as after working hours and
during weekends. This puts highly concentrated corrosive chemicals in direct contact with dry
stainless steel surfaces, and often directly on any textiles left in the machine. Chemical
deterioration (rusting) of the stainless steel and damage to the textiles is the inevitable
result.
Pellerin Milnor Corporation accepts absolutely no responsibility whatsoever for damage to
its equipment or to any textiles therein when concentrated chemicals dribble out of the
injection tubes onto any part of the machine or its contents.
Although the injection site is flushed by washer agitation on some models and after each
injection on other models to aid the injection process, this flushing provides absolutely no
protection against harmful dribble which occurs later—when the machine is no longer in use.
One foolproof solution for “dribbling” is to completely purge the appropriate chemical
injection tube with fresh water after every injection, so that only fresh water (which cannot
cause a problem) can dribble out.
Obviously, it is the sole responsibility of the pump and/or chemical supplier (not the
machine manufacturer) to furnish such a flushing device. (We understand that such flushing
type chemical injection systems—both for retrofit to existing systems and for new
installations—are now offered by others.)
5&)%&&#
.
-+&
If the tubes, pumps, and chemical tanks are kept well below the injection point, the
likelihood of “after-hours dribbling” is reduced, but not totally eliminated.
We therefore urge that tubes from any non-flushing pumped chemical system be connected
as shown in Figure 1. Although fresh-water flushing the just-used tubes after each injection
would be better, we believe routing the tubes as indicated will probably minimize the dribbling
effect about as much as possible without flushing. Never permit tanks, pumps, or any portion of
the tubes to be higher than the injection point. If loops in the injection tubes are employed, make
sure the entire loop is well below the injection point.
Figure 1: Proper Routing of Chemical Tubing
As shown in Figure 1, all tanks, pumps, and tubing must be lower than the injection point on the
machine and must not dribble chemicals into the machine, nor leak chemicals externally onto any portion
of the machine or its surroundings.
95.!-:
+&
All ports on the inlet are plugged at the Milnor® factory. When replacing plugs with fittings
or when reinstalling plugs, always use the sealant furnished (LocTite RTV Silicone Adhesive or
equivalent). Use properly sized hose barbs, always use clamps, and check for leaks. Use the hose
barbs furnished with your machine only if they provide the proper fit for the tubes employed.
Ensure that excessive pressures cannot build up that might burst or disconnect tubing. Instruct the
operator to monitor for leaks and report any occurences.
When calibrating injections, it is permissible to remove tubes from barbed fittings to take
samples. However, always check for leaks after installing tubes and clamps. A preferable method
is to install a three-way or two two-way valves onto each injection tube for sampling.
—Concentrated liquid
chemicals leaking from a chemical system can burn skin and eyes, cause other types of
injury or illness, and corrode machine components.
• Ensure that excessive pressures cannot build up which might burst or disconnect a
chemical delivery tube.
• Ensure that there are no external chemical leaks when the system is installed or
calibrated.
• Periodically check the system for leaks during operation.
!" # $ —Chemicals dribbling into
the machine when it is idle will corrode machine components and damage any textiles
left in the machine.
• If possible, use a system that flushes the entire chemical delivery tube after each
injection.
• If a non-flushing system is used, install tanks, pumps, and tubing below the injection
point on the machine, such that chemicals travel to the machine at an upward angle.
!" % $&—Certain chemicals will react when combined.
• Connect chemical inlets as shown in Figure 2.

Multiple methods are available on System 7® and E-P Plus® washer-extractors to
accommodate chemical systems. Use this section to help determine the best method of chemical
injection and how to connect the chemical system. Always consult the schematic manual for this
machine before connecting chemical systems to the machine.
' ) ' *+ ,-—Contact with high voltage electricity will
kill or seriously injure you. Even with the Master Switch off and/or any Emergency
Stop switches off, three-phase power and control circuit power are still present at
several locations within electric boxes and electrical components.
' . / ,-—Improper wiring can cause the
machine to malfunction, risking injury to personnel, damage to machine components,
and damage to goods.
• Electrical and piping connections described in this section must be made only by
qualified, authorized personnel.
• Lock off and tag out power at the external disconnect switches for the washerextractor and for any chemical devices that provide power to the interpret relay box
(if furnished) before proceeding.
• Do not rely merely on the information in this section when wiring. Consult all
applicable electrical schematics.
• Do not reroute or rearrange any wires not specifically permitted by this instruction.
• Do not connect a common wire to ground. Use the common terminal furnished.
!" 0 + 1 2—Injection times of
less than 10 seconds are discouraged because fine adjustments are not possible and
factors such as pump lag time may cause significant variations in the amount of
chemical delivered.
• Size pumps or valves small enough for adequate control (i.e., for longer injection
times).
• Use two pumps or valves to inject a small or large quantity of the same chemical, if
required.
3$- / Injection of a consistent amount of chemical is important in controlling wash quality and
using chemicals economically. When chemicals are injected by units of time, as is done with
most washer-extractors, injections of short duration can be imprecise because of two reasons:
• Fine adjustments to the delivered quantity are not possible. For example, if an injection of
three seconds is extended by one second, the quantity delivered is theoretically increased
by more than 30 percent. However, if an injection of 20 seconds is increased by one
second, the theoretical quantity is increased by only five percent.
• Variations in the time between the start of the chemical signal and the start of the chemical
delivery into the machine can cause significant differences in the quantity of chemical
injected. In this case, if a pump starts more slowly some times than others, or if the
delivery tubes are partially empty at the start of the inject period, the quantity of chemical
delivered may vary significantly. As an example, assume a peristaltic pump moves
chemical along the delivery tube at a rate of three feet per second. If the delivery tube is
empty for three feet along its length, then one second of the injection time is spent injecting
air rather than chemical. If the programmed injection time is only three seconds, then one
third of the desired chemical is not being delivered. However, if the programmed injection
time is 20 seconds, the chemical delivery is only five percent less than desired.
Increasing the programmed injection time makes any variation less significant. Use
pumps and/or valves sized to allow inject times of at least 10 seconds. If injection times for
a specific chemical vary widely from one formula to another, consider using two pumps or
valves for the same chemical. Actuate one pump for injecting small quantities, and use
both pumps or valves for larger quantities.
"9$&-: &-:1#)—Five discrete signals (for chemicals 1 through 5)
are furnished standard on all washer extractors. These signals are available at a terminal strip on
System 7® and E-P Plus® machines. Check the nameplate on the machine to verify the model.
1#;9&#&;&-:—A five-compartment
dry supply injector mounted externally on the washer-extractors is offered optionally. The five
electrically operated flush valves are wired to chemical injection output signals at terminal strip
TBA.
57&$8$—A six port inlet is standard on all models.
Use these valveless inlets to connect tubes from remote chemical supply injection systems that
are not continuously pressurized and that deliver chemicals only when an injection is
commanded.
&#&)%&
Pumped chemical systems deliver chemicals to the machine intermittently usually via
peristaltic pumps. Inlets on the machine must be unrestricted at all times (valveless). The five port
pumped chemical inlets meet this requirement.
An inherent risk of this method of chemical injection is that concentrated chemicals can
dribble into the machine after it is shut down for the evening, causing machine and/or linen
damage. Because Milnor® has no control over the design or installation of pumped chemical
systems, Pellerin Milnor Corporation accepts absolutely no responsibility for damage to its
equipment or textiles therein caused in this way. Much more information on this subject is
provided in document BIWUUI01, “Important Instructions for Pumped Chemical Inlets” (see
table of contents). Consult this document before connecting a pumped chemical system.

Injection signals provide a 110VAC/50Hz or 120VAC/60Hz potential. Each signal can
accomodate one apparatus not exceeding 37 milliamperes. Inject signals cannot be made

This document applies to Milnor® HxJ, T5J, and 30015/30022VxJ model washer-extractors,
all of which use the Milnor® “188 Processor EP+” processor board. This board can be positively
identified by “P/N 08BH18EP_ ” appearing near the Milnor® logo on the processor board.
The Milnor® factory configures each E-P Plus® washer-extractor controller for the industry
specified by the purchaser when the machine is ordered. The configuration process consists of
setting the DIP switches on the processor board and installing the appropriate industry nameplate
on the machine faceplate. The DIP switch settings may be changed in the field, and new industry
nameplates may be obtained from your dealer or the Milnor® parts department.
To change industry configuration, turn the machine off and gain access to the processor
board.
' 6 ' -—Do not open the door to any electric box
without first turning the power off. These controls use 120VAC power or higher, which
is extremely dangerous.
The location of the DIP switches on the microprocessor board are shown in Figure 4, as are
examples of the on and off positions. Set the switches to the desired configuration according to
Table 4. Turn the machine on; the display will show the current configuration.

One-way wash: Washing routine for increased mechanical action
and minimum energy consumption. Use for smaller pieces where
tangling and “roping” is not a consideration.
2
Two-way wash: Washing routine for use with bedsheets and
other large items which tend to rope and tangle unless reversed.
3
Soak wash: The cylinder does not turn when this step type is
programmed. Use this step type only when no mechanical action
is required, as for especially delicate fabrics. Consider chemical
concentrations, bath time, and liquor temperature when using
this type of step.
4
Intermediate extract 1 (E1): This is the lowest extract speed for
HxJ, FxJ, and 36-inch and 42-inch VxJ models. For other
models, this is low extract speed, used for extractions between
baths or for final extract at low speed if machine has two-speed
extract.
5
This selection differs with machine model. For FxJ, HxJ, and 36inch and 42-inch VxJ models, this causes an intermediate extract
(E2). For other models, this is the final extract sequence. In final
extract the machine runs at intermediate extract speed for a
duration determined by machine model and configuration, the
runs at high extract speed for the remainder of the programmed
extract time. The formula ends when the commanded extract
time expires.
6
Final extract (E3): For certain models only, this is the sequence
leading to the highest extract speed. The machine executes an
intermediate extract 1 (E1) for a duration of 100 seconds. After
100 seconds at E1, the machine accelerates to E3 (high extract
speed) for the remainder of the programmed extract time. When
the programmed extract time ends, the cylinder stops and the
formula ends.
Display or Action
Explanation
!" # $ —For machines with software
date code 95005 or earlier, the minimum valid time for a final extract step is 1:45
(MMQ=013). Attempts to program final extract steps shorter than 1:45 may cause the
controller to continue indefinitely in high extract. Machines running software dated
95006 or later will terminate at the programmed time, but short extract times may not
allow the machine to achieve high extract speed.
• Never program a final extract step for less than 1:45 (MMQ=013) unless the machine
has software dated 95006 or later.
• If the step timer stops counting down at about 1:20 in a final extract, press to
terminate the program, then edit the formula to increase the duration of the final
extract beyond 1:45.

633
63.75 minutes; 63:45 is the maximum programmable time for
any single step. To achieve a bath time longer than 63:45,
program two consecutive bath steps with the first ending with a
No Drain. This effectively doubles the maximum allowable bath
time.
The total time required for a formula to run to completion includes factors other than the
total of the times of each step in the formula. For these machines, add 0:40 distribution time each
time the machine enters an extract step from a bath step. Also, add 1:00 for each standard drain
(drain speed), or 1:00 for each two-way wash drain.

temperature decision for correction. See section 2.3.3.5.3 for details on how to regulate the
temperature of incoming water.
!"# —When
programming a thermo-modulated temperature for a bath using both hot and cold water valves,
the relationship between the desired temperature and the temperature of a split fill (hot and cold
valves open simultaneously) is important.
If the desired temperature is hotter than the normal split temperature, a faster, more accurate
fill with a more constant temperature is achieved by programming the hot water valve open (H=1)
and the cold water valve to open only to lower the fill temperature (C=3).
If the desired temperature is colder than the normal split temperature, similar results can be
achieved by programming the hot water valve to open only to raise the fill temperature (H=2) and
the cold water valve to remain open constantly (C=1).
$—A cooldown is programmed as a separate bath step following the
bath in which the cooldown is desired. In the cooldown step, command a desired cooldown
temperature with all water valves programmed off (0). The E-P Plus® control automatically
inserts a no drain in the previous bath and 010 in MMQ, for a step time of 1:00.
The commanded cooldown temperature must always be at least 15 degrees Fahrenheit (8
degrees Celsius) hotter than the hottest ambient temperature or the hottest cold water temperature
that will be encountered. If this rule is not followed, achieving the desired cooler temperature
may take a long time, or even be impossible.
After the desired cooldown temperature has been achieved for 15 seconds, the cooldown
process will continue for one minute. Upon completion of the cooldown process, the machine will
drain unless a no drain was programmed to prolong the cooldown bath. Prolonging of the
cooldown bath is useful especially in cases where chemicals are to be added to the cooler bath
liquor.

The six available steam codes are combinations of three yes/no decisions, as described
below.
• Early refers to whether steaming should begin at the lowest safe level, or if steaming should
only begin after the commanded level is achieved. Usually, a “Start Steaming Early” code (4,
5, or 6) is used when the machine receives only cold water or when the hot water in the plant
has a relatively low temperature. Use a No response if the machine has both hot and cold
water valves and the commanded temperature is lower than the hot water temperature.
• After refers to whether steam is allowed in this bath after temperature has been achieved once
and subsequently fallen below the commanded temperature. A No response prevents a second
steaming after temperature is first achieved. Use No if chemicals or goods may be damaged
by steam after a chemical injection (as in bleach baths).
• Timer refers to whether the timer runs or stops while steaming up to temperature. Stops
causes the timer to stop counting until the commanded temperature is first achieved. Runs is
for use when some temperature fluctuations are acceptable or when it is certain that the
commanded temperature will be nearly achieved while filling. Use Stops if temperature must
be achieved before adding chemicals, otherwise software will suppress this chemical-add
choice.

Because the microprocessor control system used in this machine is capable of controlling
several different models with a wide variety of options, each unit must be configured to match its
specific model and type of washer-extractor. This configuration informs the microprocessor of
the characteristics of this machine, such as the number of water valves, the presence of
temperature control, cooldown, etc. Such decisions are discrete to the specific machine and must
never be changed unless options are later added or removed. In addition to these hardwarespecific decisions, certain configuration choices, such as the display of English or metric units,
are left to the discretion of the owner/operator.

accidentally or intentionally while in the Configure mode, all configuration data may be

Explanation
0
This decision appears only if the machine is configured for
temperature control (described above).
Select 0=No Steam if the machine is not equipped for steaming,
as in the case of a machine with temperature control used
exclusively for cooldown.
Select from options 1 through 3 if steam is available. The
number of minutes selected is the maximum time that the
machine will steam in an attempt to achieve the desired
temperature before a steam error is displayed. This self-clearing
error does not stop machine operation. However, for formula
steps where the timer is commanded to stop while steaming until
the desired temperature is achieved, production may be severly
restricted by steam errors.
COOLDOWN ERROR ?
0 = NO COOLDOWN
0
This decision appears only if the machine is configured, and
equipped with the mechanical and electrical hardware for
temperature control (described above).
Select 0=No Cooldown if the machine is not equipped for
cooldown, as in the case of a machine with temperature control
used exclusively for steaming.
Select from options 1 through 3 if cooldown is available. The
number of minutes selected is the maximum time that the
machine will cooldown in an attempt to achieve the desired
temperature before an error is displayed. The error is selfclearing and does not stop machine operation. However,
production may be severly restricted by cooldown errors if the
cooldown temperature is set lower than the incoming cold water
temperature.
WATER LEVEL UNITS?

1
Select 0=CM to have the water level displayed in centimeters.
OFFSET HEIGHT ?
18
This value is set at the Milnor® factory to compensate for the
height difference between bottom of the cylinder and the
location of the pressure tube connection on the drain sump.
Because the pressure tube between the pressure transducer and
the cylinder connects at an elevation not exactly equal to the
bottom of the cylinder, this value allows for an accurate display
of the water level. The unit of this value is tenths of an inch, so a
difference of 1.8 inches is entered as 18. The maximum
allowable value is 3 inches prior to software version 97004, and
4.5 inches with software versions 97004 and later.
LOW LEVEL HEIGHT ?
6
This value is the depth of the water measured from the bottom of
the cylinder shell. This level will be used for any programmed
bath step commanding a low level of bath liquor.

Explanation
The Run/Program keyswitch must be set to the Run position
before the main wall disconnect (fuse or circuit breaker) is
closed to provide power to the machine.
When power is first applied to the machine, the display shows the software copyright
information, machine name, and the checksum number. The checksum number changes with any
programming change. To detect unauthorized programming, record the checksum at the end of
each authorized programming session and compare it to the checksum displayed at each power
up.
Some Milnor® washer extractors with E-P Plus® controls do not use a speed sensing device
to verify that the basket has stopped rotating. Therefore, when power is first applied to the
machine, at least 80 seconds must elapse before any further operations can be attempted. This
provides sufficient time for the basket to coast to a complete stop if power was lost while the
machine was in a high speed extract and restored before the basket stopped.

The E-P Plus® controller includes an output signal that activates the flush valve for 30
seconds after the last chemical has been injected into each bath. If a bath is shortened or
terminated before of while this valve is energized, the flush valve will be turned off. Shortening
or terminating a bath may prevent the flush valve from activating.

Goods must be cool enough to handle immediately after a wash cycle is finished. However, a
drastic temperature change may set wrinkles in goods of certain fabrics. Therefore, many Milnor®
washer extractors employ a feature called cooldown to gradually lower the water temperature and
thus provide cool goods at the end of the wash cycle without setting wrinkles.
For HxJ models, the cooldown valve is turned on until high (cooldown) level is reached.
This causes the drain to open and the cooldown valve to close until high level is lost. When high
level is lost, the drain closes and the cooldown valve opens. This process continues until the
cooldown step is complete.

There is one unique number which identifies each possible combination of on/off settings at
the DIP switch. While the industry configuration (switch 1 through switch 4) is readily available
from the Software version mode (described in section 4.1.2 Determining the Software Version),
the settings of other switch positions are only apparent from this display or by visually inspecting
the processor board.

The Test Temperature & Level selection on the Manual menu is designed primarily for use
by the Milnor® factory for testing and calibration of machines before delivery. The display is
explained briefly here, as special testing equipment is required to make adjustments from this
display.
Display or Action
R00088 A:01.0 C:01.0
R00099 A:082F [TEMP]
Explanation
The top line of the display applies to the level sensing circuit.
The “R” and the five characters immediately following it on the
top line indicate the voltage being delivered by the pressure
transducer on the processor board (see Figure 5). The “A” value
is the actual instantaneous level read by the transducer. Because
this display is only available when the drain is open, the actual
level will normally reflect no water in the machine cylinder. The
“C” value is a calculated average of the transducer levels, used
to negate the effects of rising and falling water levels caused by
the reversing wash motion. Again, in normal conditions, this
value will reflect that there is no water in the machine.
The bottom line of the display applies to the temperature sensing
circuit. Similar to the “R” value of the top line, the first six
characters of the bottom line indicate the voltage being delivered
by the temperature probe to the processor board (see Figure 5).
The “A” value on the bottom line is the temperature in degrees
Fahrenheit detected by the temperature probe.

If an error message appears during power up, the error must be cleared before the machine
can be run or programmed.
Display or Action
Explanation
The microprocessor performs a memory check each time the
machine is turned on. This error message appears if the
microprocessor detects that the accumulator data is corrupt, in
which case all accumulators must be reset to zero.
ACCUMULATOR ERROR
TERMINATE TO CLEAR
CHECKSUM ERROR,
TURN KEY TO PROGRAM
Resets all accumulators and clears the error message. See
“Viewing and Clearing the Formula Count Accumulator” (see
Table of Contents) for more information.
Appears if there is illegal data in the configuration, formula, or
industry memory areas. Use the following procedure to clear this
error.
1. Reconfigure the machine according to the configuration information in “Programming the EP Plus® Control” (see Table of Contents).
2. Reinstall the standard (default) formulas according to the default formula loading procedure
in “Programming the E-P Plus® Control”.
3. Reprogram any lost wash formulas according to “Programming the E-P Plus® Control”.
MEMORY: FLASH
IS NOT TALKING
This message appears when the microprocessor cannot read from
the flash memory.
1. Lock off and tag out power to the machine.
2. Replace flash memory. Contact the Milnor® factory to ensure that the replacement memory is
the most current version for your machine.
3. Restore power to machine.
4. Reconfigure the machine according to the configuration information in “Programming the EP Plus® Control” (see Table of Contents).
5. Reinstall the standard (default) formulas according to the default formula loading procedure
in “Programming the E-P Plus® Control”.
6. Reprogram lost wash formulas according to “Programming the E-P Plus® Control”.
A/D BOARD IS NOT
TALKING
This error message indicates that the analog to digital board is
not communicating with the microprocessor.
1. Lock off and tag out power to the machine.
2. Check the connections at both ends of the ribbon cable between the processor board and the
analog to digital board.
3. Restore power.
4. If the error persists, lock off and tag out power to the machine. Have a qualified service
technician replace the the suspect board.

If an error message appears on the bottom line of the display while the machine is running,
the timer shown on the top line will stop counting. When the error is corrected, the timer resumes
counting down. To troubleshoot most errors, suspend the formula in progress and turn power off.
Do not terminate the formula if it is to be resumed after the error is corrected. See "Running a
Formula" for more information.

CHECK PROBE
EXTERNAL FAULT
INVERTER FAULT
Explanation
This error message indicates that the door input is not made
while the machine is running. Verify that the door is closed, then
check the door switch and its connection to the microprocessor.
Press if necessary to resume operation after the error is
corrected. Never operate this machine while this message is
present.
The level switch may be faulty, perhaps reporting that level 2
was achieved before level 1. Check the level switch and its input
connection to the microprocessor.
The microprocessor is still receiving information that a level is
made just before or during an extract step, or immediately before
the fill for a bath step. This error is self-clearing when level is
lost.
Time to fill to level exceeded 10 minutes. Check the water
valves, strainers, supply lines, and water pressure. The machine
will continue to fill until level is reached, at which time the error
will automatically clear and normal operation will resume.
The configured maximum time to steam up to the desired
temperature has been exceeded. Check the steam valve, strainer,
main steam header and pressure, etc. Steaming will continue
until temperature is achieved, when the error will automatically
clear and normal operation will resume.
The configured maximum time to cool down to the desired
temperature has been exceeded. Check the cooldown valve and
strainer if equipped, cold water pressure, and position of vernier
valve on cooldown inlet. Cooldown will continue until the
desired temperature is achieved, when the error will
automatically clear.
The machine did not drain properly in the allotted drain time.
This self-correcting error will clear when the water level in the
basket is low enough to begin the next operation.
This error message indicates that the resistance of the
temperature probe is outside the specified range. Test the probe
by disconnecting the probe leads from the processor board and
checking the resistance with an accurate digital ohmmeter.
Resistance between the two leads must be between 2K and 35K
Ohms. Resistance between each lead and ground must be
infinite.
The programmed chemical injection failed, usually because the
chemical supply system is empty. When chemicals are added
and can be injected, this error will clear automatically, allowing
operation to resume.
This error message appears if the microprocessor does not
receive an input from the inverter within 14 seconds of the
beginning of the formula. After 14 seconds without an inverter
input, the timer stops, the basket is stationary, and the drain
valve opens. To recover, press the Next key ().

VIBRATION SW TRIPPED
RECOVERY SEQUENCE
Explanation
When the vibration switch closes, the timer stops. After 80
seconds, the basket reverses at wash speed as the cylinder fills
with water. When low level is achieved, the cylinder reverses for
one additional minute at wash speed, then accelerates to extract
speed.

The Milnor® E-P Plus® microprocessor control is designed specifically for Milnor® washerextractors. Along with certain external electromechanical relay logic and sensing devices, it
controls all machine and system functions. Not every microprocessor system includes all the
following components.

Machines in the FxJ and HxJ model lines, as well as the 30015 and 30022VxJ models, use a
vacuum fluorescent display consisting of two lines of 20 characters each. This type of display is
easily identified by green characters on a black background when operating, or a nearly black
background when not operating.
,)##%
The power supply serves to provide a regulated specific voltage to the processor board and
certain auxiliary boards and devices. It converts control circuit alternating current voltage to +12
volts direct current, –12 volts direct current, and +5 volts direct current. The power supply is
switchable between 120 volts and 240 volts alternating current input voltage.
Although the +12VDC and –12VDC are not adjustable, the +5VDC is rather sensitive and
the power supply must be adjusted so the actual voltage at the processor board is between
5.04VDC and 5.06VDC as measured by an accurate digital voltmeter. If this voltage is not
within the stated range, the machine is likely to malfunction.

The central processing unit (CPU) processes data received from the various inputs, stores
information, and responds to each pushbutton entry with the appropriate action. Data is stored in
one or more of the following types of memory chips on the CPU board, depending on the
machine model.
SRAM—Static Random Access Memory stores the accumulator (formula count) data as long as
the machine has power, or via a capacitor for approximately 24 hours with power off. This
type of component is also used to retain the last formula and step in progress when power is
turned off at the machine while a formula is running. SRAM is used in all E-P Plus®
controllers.
Flash Memory—similar to EEPROM memory in function, flash memory can be electrically
erased and reprogrammed, but is faster and can retain more data than EEPROM memory.
Flash memory is used only on 188 processor boards (those used in HxJ, T5J, and 30015 and
30022VxJ models). The two flash memory chips reside in sockets IC2 and IC12. The chip in
socket IC12 contains operating instructions and the complete set of industry standard
formulas. As software updates are made available, this chip will be replaced. The chip in
socket IC2 holds the industry formulas and user changes to those formulas, as well as machine
configuration data. The chip in socket IC2 will not normally need replacing for software
updates.

Depending on the processor board, output relays may be either socket-mounted to a separate
output board, or permanently soldered to the processor board. HxJ, TxJ, and 30015 and 30022VxJ
models use the 188 processor board with soldered relays.
For models other than the HxJ, TxJ, and 30015 and 30022VxJ, the 16 output relays are
socket-mounted SPDT electromechanical relays with contacts capable of faithfully conducting a
maximum of 25VA (0.1 ampere (100 millliamperes) at 220/240VAC, or 0.2 amperes (200
milliamperes) at a maximum of 110/120VAC). The output voltage will be either 220/240VAC or
110/120VAC, depending on machine model and type.
These outputs and their power source are intended only to drive another relay with higher
contact ratings that may, in turn, drive a pump, valve, solenoid, etc. from a separate power source.
Never use these outputs to directly drive a pump, valve, or solenoid unless the maximum current
required never exceeds the above values. Higher ampere or VA loads will burn out traces on the
printed circuit board or possibly overload and damage the control circuit transformer.
Machines in the HxJ, TxJ, and 30015 and 30022VxJ model lines use the 188 processor board
with output relays soldered to the processor board. These relays have the same load parameters as
those used in other models, but are SPST (single pole, single throw) rather than the SPDT (single
pole, double throw) relays used on the 788 board.
## —Although the relays on
188 processor boards are capable of handling higher loads, failure to restrict current
loads to the values stated above may cause traces on the processor board to fail, thus
destroying the board.

The 188 E-P Plus® processor board used in HxJ, TxJ, and 30015 and 30022VxJ models

22 of the output relays on the 188 processor board are identical.

This component converts analog signals, such as from the temperature probe, to a digital
signal that can be used by the microprocessor. The A/D convertor is a part of the 188 processor
board used in HxJ, TxJ, and 30015 and 30022VxJ models. The A/D convertor also provides a
fixed voltage which is used as a reference for sensing temperature.

A thermistor temperature probe is provided in the machine sump if the machine is equiped
for optional temperature control. This probe is a resistor that changes value according to
temperature.

The 188 E-P Plus® processor board, used in all HxJ, TxJ, and 30015 and 30022VxJ models,
contains a pressure transducer unit mounted directly to the board. This transducer produces a very
small voltage that increases as the water level in the basket rises.
