INSTALLATION INSTRUCTIONS

All washers must be installed in accordance with all local, state and national
building, electrical, plumbing and other codes in effect in the area.

WARNING - THESE INSTALLATION AND SERVICING
INSTRUCTIONS ARE FOR USE BY QUALIFIED PERSONNEL ONLY.
TO AVOID INJURY AND ELECTRICAL SHOCK DO NOT PERFORM
ANY SERVICING OTHER THAN THAT CONTAINED IN THE
OPERATING INSTRUCTIONS, UNLESS QUALIFIED.

FOUNDATION REQUIREMENTS

This machine is designed for use on or over bare concrete floor - not to be used above
combustible flooring. The washer must be securely bolted and grouted to a
substantial concrete floor, or mounted and grouted upon a suitable base that is
securely bolted and grouted to a substantial concrete floor. CARE MUST BE
STRESSED WITH ALL FOUNDATION WORK TO INSURE A STABLE UNIT INSTALLATION,
ELIMINATING POSSIBILITIES OF EXCESSIVE VIBRATION. All installations must be
made on sound concrete floors, 8 inches (203 mm) or thicker. Anchor bolts or
expansion anchors must be of a quality grade and a minimum of 3/4-inch (19 mm)
diameter. Six bolts are required to mount the washer to the steel base or concrete pad.

MOUNTING

A concrete pedestal or steel-mounting base that elevates the machine approximately 4
inches (102 mm) above the floor level is recommended to provide easy access to the
loading door. Allow a minimum of 24 inches (610mm) of clearance behind the rear of
the machine, to provide access for motor removal. Refer to Fig. 1-1 and 1-2 for
machine bolt-down dimensions.

If an elevated concrete pedestal is desired, it should be embedded into the existing
floor. Anchor bolts should be 3/4" x 8" (19 mm x 200 mm), grade 8 or better, headed
by a 4 inch (10 cm) square fish plate and should protrude 2 1/2” (64 mm) above the
finished surface of the pedestal. EXPANSION ANCHORS ARE NOT RECOMMENDED FOR
USE IN CONCRETE PEDESTALS, BECAUSE THE ANCHORS ARE TOO CLOSE TO AN
EDGE, CAUSING IT TO BREAK OUT. (See Fig. 1-1 and 1-3.)

PLUMBING

Water supply hoses are furnished with each machine. The threaded connections on the
hoses are ¾-11 ½ NHT.

Separate hot and cold water lines must be provided, maintaining 30 psi to 120 psi (207 kPa
to 827 kPa) water flow pressure. A 140F (60C) degree hot water supply is recommended
for best washing results. Do not exceed 180F (82C) degree water temperature.

DRAIN

The drain outlet tube at the rear of the machine is 3 inches (76 mm) in diameter. Any
drain hose used must be lower than the drain valve to assure proper draining.

ELECTRICAL

WARNING

SHUT OFF POWER AND WATER BEFORE OPENING ANY SERVICE PANELS.

The Dexter T-650 single/three-phase 208-240VAC 60 Hz washing machines are intended to
be permanently installed appliances. No power cord is provided. The machine should be
connected to an individual branch circuit not shared by lighting or other equipment. The
connection should be sheathed in liquid tight flexible conduit, or equivalent, with
conductors of the proper size and insulation. A qualified technician should make such
connections in accordance with the wiring diagram. (Suggest a minimum wire size of 12
ga.)

TO MAKE ELECTRICAL CONNECTIONS: Disconnect all power to the washer. Remove the
top panel of the washer and locate the power terminal block near the back of the control
compartment.

 If power is 208-240-3PH-60Hz, connect L1, L2, L3 and ground. If there is a high leg it

must be connected to L3. However, failure due to a voltage surge on the high leg is
not covered by equipment warranty. Contact Dexter Laundry with any questions.

 If power is 208-240-1PH-60Hz, connect L1, L2 and Ground.

NOTE: It is important that the grounding screw next to the power terminal block TB­1 be connected to a good external ground.

8514-256-001 REV PR page 6

FUSING REQUIREMENTS:

SINGLE- and THREE -PHASE 208-240VAC MODELS - 15 AMP TIME-DELAY (DUAL
ELEMENT) FUSE (or equivalent circuit breaker)

CONTROLS TRANSFORMER

The controls transformer is located inside the control trough and steps a range of 208 to
240 volts down to 115 volts. There are two terminals on the controls transformer for the
primary (incoming) power. Use the terminal marked “208V” for power supplies between
208 and 219 volts. Use the terminal marked “240V” for power supplies between 220 and
240 volts.

CHECKOUT

After all mounting, plumbing and electrical work is completed; the washer should be run
through a cycle and checked for water leaks and proper functioning.

The cylinder should turn in a counterclockwise direction (viewed from the front of the
machine) during intermediate spin and final spin. If spin is clockwise, the T1 and T2
motor wires going to T1 and T2 on the variable frequency drive should be swapped.
Remove power to the machine before swapping wires.

8514-256-001 REV PR page 7

OPERATING INSTRUCTIONS - STARTING THE WASHER

A. Load the clothes into the cylinder and latch the door securely. Be sure
clothing does not get caught between the door gasket and tub front when
closing the door. Maximum load is 40 pounds clothes, dry weight. Do not load
the washer with more than 40 lbs.

B. Select the appropriate cycle temperatures for the load being washed.

C. Add low sudsing powdered detergent into the “detergent” compartment of
the automatic dispenser on the top of the washer. If desired add fabric softener
to the “fabric softener” compartment. Use the amount of fabric softener as
recommended by the manufacturer.

If liquid wash products are used in the “detergent” compartment, they must be
added at the beginning of the wash cycle.

If the machine is set for pre-wash, washing products can be added to the round
opening of the dispenser or put in with the clothes when loading the washing
machine.

D. Insert coins, tokens or debit card to meet the displayed vend price. The
display will count down the amount needed to meet the vend price. Once the
vend price is met, the display will read “PRESS START” and the start button LED
will blink. If the door is not closed and latched, the display will read “CLOSE
DOOR” and the control will wait until the door is latched to continue. Pressing the
start button will begin the cycle and activate the ON light. The display will show
the remaining cycle time in minutes. The clothes door will lock and remain
locked until the end of the cycle.

END OF CYCLE

When the cycle is complete a 3-second tone will sound and the display will read “CYCLE
DONE THANK YOU” until the door is opened. The door can now be opened. Leave the
clothes door open when the machine is not in use.

8514-256-001 REV PR page 8

EMERGENCY STOP / SAFETY DOOR LOCK

This machine is equipped with a Safety Door Lock that locks the door closed from when
the cycle is started until the cycle is complete. The door lock prevents opening the door
for up to 3 minutes if the power is interrupted during the cycle.

The Emergency Stop button pauses the washer and allows the door to be opened
during the cycle after the Safety Door Lock releases. When the Emergency Stop button
is pressed an alarm will sound and the display will begin counting down and read “STOP
3”, “STOP 2”, “STOP 1”. If the button is released before 3 seconds elapse, the alarm
will stop and the cycle will continue normally. If the Emergency Stop is held down for 3
seconds, the display will count down and the washer will begin stopping movement and
water flow and begin draining water from inside the washer. Though the machine may
stop wash movement quickly, it may take up to 3 minutes for the door to unlock.
During that time the alarm will continue to sound and the display will read “STOPPING”.
When the alarm stops, the door may be opened. The washer may be restarted by
closing and latching the door, and pressing the Start button. If the washer was stopped
more than once before the final extract, the cycle will be cancelled. If the washer was
stopped during final extract, the cycle will be ended. If the washer is stopped for more
than 1 hour, the cycle will be terminated.

8514-256-001 REV PR page 9

PROGRAMMING THE WASHER CONTROL

The washer control can be programmed to prompt the user for alternate vend prices,
change washer cycle times, temperatures and many other options. This can be
accomplished in two ways:

1. Manual programming utilizing the “Start”, “Hot”, “Warm” and “Cold” buttons

2. USB download of a customizable User File. For instructions on using the USB
download feature, please contact your local Dexter distributor or visit
dexterlive.com.

MANUAL PROGRAMMING:

The washer must be in idle mode for the manual programming menus to be accessed.
Idle mode is when the washer is not actively running a wash cycle and the vend price is
displayed on the screen.

To enter the manual programming mode, the top of the washer must be unlocked and
lifted slightly (it may be necessary to remove the screws for the soap box). The
programming button is then pressed for 1 second. The control should display
“PROGRAMMING”.

See the figure below for the location of the programming button in relation to the USB
port (The USB port is exposed when the washer top is lifted).

8514-256-001 REV PR page 10

When manual programming mode is entered, the “Start”, “Hot”, “Warm” and “Cold”
buttons perform alternate functions.

Button Name Alternate Function in Programming Mode

Start

Hot

Warm

Cold

Becomes the action to accept the displayed option or
the “Enter” key
Becomes the action to move UP through displayed
options (Press & hold for accelerated scrolling)
Becomes the action to move DOWN through displayed
options (Press & hold for accelerated scrolling)
Becomes the action to move back a step (1 press) or
EXIT from programming mode (press for 3 seconds)

These alternate functions allow the user to move through a menu of options to choose
various programmable settings. The figure below shows the top level menu. Choosing
an option from the top level menu will then display the next level of options (the sub
menu).

8514-256-001 REV PR page 11

Quick Test Option:

When the Quick Test Option is chosen, the washer will begin a shortened wash cycle
without the displayed vend price being met. The purpose of this shortened cycle is to
test all major components for proper operation.
Error Codes should all function normally during this test. The display will show customer
prompts in a similar way to a normal wash cycle. Exceptions to this are that the “ADD
BLEACH” prompt will not occur because of reduced cycle time. Final Extract speed is
specific to the customer’s programming.

Rapid Advance Option:

Similar to the Quick Test, when the Rapid Advance Option is chosen, the washer will
begin a wash cycle without the displayed vend price being met. However, in this case, it
will be a normal default cycle with an additional feature available. The “Start” button
LED will flash, prompting the user that, when pressed, the washer shall rapid advance
to the next step in the cycle. The display will show “ADVANCE” when the cycle is
advancing. The water level needs to be empty before this advance occurs. During the
time waiting for the tub to empty, the “ADVANCE” prompt will be held on the display
and the start pushbutton LED stops flashing. The Rapid Advance shall allow the tub to
empty of water and the tub to stop before beginning either spin or the next bath.

The Rapid Advance mode can be exited by pressing the programming button. This will
end the cycle. When the Rapid Advance mode is used, the cycle time will no longer be
correct. By skipping steps with Rapid Advance, the door may not open immediately at
the end of the cycle.

Error Code Historical Log:

The last five occurring error codes will be stored in the control with a time and date
stamp. The purpose of this option is only to observe the history of these code
occurrences (no changes can be made).

The time is based off the Real Time Clock, but potentially shifted by the user’s manual
programming changes (Shift Hours option) and/or network time override. As additional
error codes occur, the oldest of the five logged codes is cleared from memory.

8514-256-001 REV PR page 12

Prices Option:

This option allows the user to set values for coin acceptor inputs and to set the vend
price. It also allows the user to return the values to factory defaults. After changing
prices using the “Up” or “Down” buttons, the “Enter” button must be pressed again for
the control to store the changes that have been made.

1. “RIGHT COIN” and “LEFT COIN” are the two possible inputs from coin acceptors.

2. “SET VEND” is the actual Base Vend Price (or Vend Price A) that is shown on the
control display.

To reset either the coin acceptor inputs or the vend price to factory default, press
“Enter” when the “DEFAULT” prompt is shown. Press “Enter” again when the “RESET”
prompt is shown to confirm the action.

The figure below shows the sub menu options for Prices:

Temp Pricing Option:

The Temperature Pricing option allows for the user to prompt the customer for varying
vend prices based on the water temperature the customer selects. If a value other then
0 is programmed for either the “WARM ADDER” or “HOT ADDER”, the feature becomes
active. The programmed value is added to the base vend price when that particular
water temperature is chosen.

When the customer adds coins to meet the adjusted vend price and starts the washer,
the temperature selections available to the customer are limited to those with vend
prices equal to or less than the amount entered.

The figure below shows the sub menu options for Temp Pricing:

8514-256-001 REV PR page 13

Cycles Option:

This option allows the user to set the bath time and spin time for the “Wash” bath. It
also allows the user to set bath time, water temperature and spin time for “Rinse” and
“Final rinse” baths. (Water temperature for the “Wash” bath is chosen by the customer
using the “Hot”, “Warm” and “Cold” buttons on the front of the machine). For the
“Final Spin” it also allows the user to set the spin speed (see additional description
below).

It also allows the user to return the values to factory defaults. To reset all values in the
Cycles option to factory default, press “Enter” when the “DEFAULT” prompt is shown.
Press “Enter” again when the “RESET” prompt is shown to confirm the action.

1. “Final Spin” is the spin that occurs after all selected baths & intermediate spins
have been completed. It is a higher spin speed than previously occurring
intermediate spins. The benefit of this higher spin speed is that more water is
extracted from the wash load, which minimizes the drying time needed.
However, in some cases, if the Dexter installation guidelines are not followed
properly, it may be necessary to reduce the spin speed of the “Final Spin”.

The “Final Spin” can be adjusted in increments of 10 G for washers with a 100G
maximum spin speed and increments of 20 G for washers with a 200G maximum
spin speed. The factory default “Final spin” speeds are the maximum values.

Model Adjustable Final Spin

Range
T-300 60G to 100G
T-350 60G to 200G
T-400 60G to 100G
T-450 or T-450 SWD 60G to 200G
T-600 60G to 100G
T-650 60G to 200G
T-750 60G to 200G
T-900 60G to 100G
T-950 60G to 200G
T-1200 60G to 100G
T-1450 60G to 200G

2. “Delay Fill” is meant to be used in applications where the amount of available
water pressure is limited. In these cases, the washer may not be able to fill the
tub in sufficient time to allow for effective washing performance.

When the “Delay Fill” option is “On”, the water valves shall be turned on, the
washer shall agitate, but the cycle time shall be paused. The washer shall
continue in this state until the proper water level is reached. Once the proper
water level is reached, the cycle shall continue. A single selection of “On” or “Off”
shall apply to all baths in the cycle. The factory default setting is “Off”.

8514-256-001 REV PR page 14

3. “Delay Spin” is meant to be used in applications where the amount of drain
capacity is limited. In these cases the washer cannot empty the tub in sufficient
time to allow for a spin cycle to occur.

When a time value (other than 0) is programmed for the “Delay Spin” option, the
end of each bath will be extended by the selected time. Therefore, extra time will
be allowed for the drain valve to be open and compensate for slow drain
capacity. The factory default setting is 0 seconds.

4. “Default Temp” allows the user to choose which water temperature (“Hot”,
“Warm”, or “Cold”) will be active during Idle mode. The customer can, of course,
choose other temperatures for the wash bath based on other options described
in this manual.

The figure below shows the sub menu options for Cycles:

8514-256-001 REV PR page 15

Plus Cycle Options:

The “Plus Cycle” options allow for the user to prompt the customer for varying vend
prices based on additional wash baths chosen. In general, the user can program the
additional wash baths in a similar manner to what was described in the “Cycles” Options
section.

It also allows the user to return the programmable values to the factory default setting.
No plus cycle options are active using the factory default. To reset all values in the Plus
Cycles option to factory default, press “Enter” when the “DEFAULT” prompt is shown.
Press “Enter” again when the “RESET” prompt is shown to confirm the action.

1. “Pre-Wash”- If the user programs a “Cycle Time” for “Pre-Wash” other than 0
(“No Cycle”), the feature becomes active. However, the customer will not be
prompted to pay an additional vend price for “Pre-Wash” unless the user
programs the Price to a value other than 0 (“Free”). With the “Pre-Wash”
feature active, an additional bath and, optionally, an additional spin, will occur
before the standard Wash bath described in the Cycles Options section.

With the “Pre-Wash” feature active and a “Price” value programmed, the
customer will be prompted to add additional coins if they wish to purchase the
“Pre-Wash” feature. This will occur after they have entered coins to meet the
Base Vend price. If the customer does not meet the vend price of the “Pre­Wash” feature, the prompt will time out and the “Pre-Wash” bath will not occur.

2. “Extend Wash”- If the user programs an “Extend Time” for “Extend Wash” other
than 0, the feature becomes active. However, the customer will not be prompted
to pay an additional vend price for “Extend Wash” unless the user programs the
Price to a value other than 0 (“Free”).

With the “Extend Wash” feature active, the standard Wash bath described in the
Cycles section will be extended for the additional time selected. With the “Extend
Wash” feature active and a “Price” value programmed, the customer will be
prompted to add additional coins if they wish to purchase the “Extend Wash”
feature. This will occur after they have pressed the “Start” button to begin the
normal Wash cycle. If the customer does not meet the vend price of the “Extend
Wash” feature, the prompt will time out and the additional time will not be added
to the Wash bath.

3. “Extra Rinse”- If the user programs a “Cycle Time” for “Extra Rinse” other than 0
(“No Cycle”), the feature becomes active. However, the customer will not be
prompted to pay an additional vend price for “Extra Rinse” unless the user
programs the Price to a value other than 0 (“Free”).

With the “Extra Rinse” feature active, an additional bath and, optionally, an
additional spin, will occur after the standard “Final Rinse” bath described in the
Cycles Options section. With the “Extra Rinse” feature active and a Price value
programmed, the customer will be prompted to add additional coins if they wish
to purchase the “Extra Rinse” feature. This prompt will occur during the standard

8514-256-001 REV PR page 16

“Final Rinse” bath. If the customer does not meet the vend price of the “Extra
Rinse” feature, the prompt will time out and the “Extra Rinse” bath will not occur.

The figure below shows the sub menu options for Plus Cycle Options:

8514-256-001 REV PR page 17

Settings:

The “Settings” options allow for the user to make various programming changes to
change how the control operation affects the customer. See below for detailed
information on each next level option.

1. “Decimal Point”- If the user programs the Decimal Point to “OFF”, control display
will not show a decimal point on any vend price values. The factory default is
“ON”.

2. “Sounds”- If the user programs the Sounds to “OFF”, the control will not sound
the enunciator at the end of a wash cycle. The factory default is “ON”.

3. “Password”- If the user programs the password to any value other then 0000,
the control will prompt the user to enter a password (the programmed value)
before manual programming can be accessed. The factory default is “0000” (no
password).

a. Note that if the user forgets the Password, it can be reset to factory

default (no password), by performing a hard reset on the control. Please
refer to the appropriate section of this manual to understand how to
perform a hard reset.

b. The individual digits of the Password can be set by using the “Up” or

“Down” buttons to change the number that is flashing. Once the desired
number is chosen for a single digit, press the “Enter” button to move to
the next one. Once all four desired digits are chosen, the “Enter” button
must be held down for 3 seconds to confirm that the complete password
should be set.

4. “Language”- The control uses English for the default language of the customer
prompts. Alternatively, the user can choose Spanish or French for the customer
display prompts. However, all other prompts, such as Manual Programming, USB
Programming and any Error Codes will still display in English.

5. “Shift Hours”- This feature allows the user to shift the time used by the control
from the time kept internally by the control. The control uses a Real Time Clock
(RTC) to internally track the time and date. The RTC continues operation even if
the control loses external power. The RTC is set for Central Standard Time and
no daylight savings. Because the machine may be located in another time zone,
the user can choose to create an alternate time & date that tracks in parallel to
the RTC. When this alternate time is chosen, or shifted from the RTC, the
alternate time will be used to, for example, track error code occurrences and set
time-of-day pricing changes.

a. The hours in “SHIFT HOURS” can be set by using the “Up” or “Down”

buttons to change the number that is flashing. Once the desired hour shift
is chosen, press the “Enter” button to move to the minutes. Once the
hours and minute shift are both chosen, the “Enter” button must be held
down for 3 seconds to confirm that the complete shifted time is set.

6. “Time”- The control uses a Real Time Clock (RTC) to internally track the time and
date. The RTC continues operation even if the control loses external power. The
RTC is set for Central Standard Time and no daylight savings. However, if a
problem occurs and the RTC time is not accurate, it can be reset to the current
time using this option.

a. The hours in “TIME” can be set by using the “Up” or “Down” buttons to

change the number that is flashing. Once the desired hour is chosen,

8514-256-001 REV PR page 18

press the “Enter” button to move to the minutes. Once the hours and
minute are both chosen, the “Enter” button must be held down for 3
seconds to confirm that RTC is meant to be reset to the complete entry.

7. “Date”- Similar to “Time”, if a problem occurs and the RTC date is not accurate, it
can be reset to the current date using this option.

a. The day of the month in “DATE” can be set by using the “Up” or “Down”

buttons to change the number that is flashing. Once the desired day of
the month is chosen, press the “Enter” button to move to the month of
the year. Once the desired month of the year is chosen, press the “Enter”
button to move to the year. Once the day, month and year are all chosen,
the “Enter” button must be held down for 3 seconds to confirm that RTC is
meant to be reset to the complete entry.

8. “Drive Table”- The control knows what model of washer it is installed in based on
various inputs including information it receives from the Variable Frequency Drive
(VFD). However, because multiple VFD’s can be used on the same model,
depending on when it was manufactured, the “DRIVE TABLE” option is available.
Any new washer should have the “DRIVE TABLE” programmed to the “CURRENT”
option. However, in older washers that have been retrofitted with a new control,
the “CLASSIC” option should be chosen. Contact your local Dexter distributor for
more information.

To reset all values in the Settings options to factory default, press “Enter” when the
“DEFAULT” prompt is shown. Press “Enter” again when the “RESET” prompt is shown to
confirm the action.

The figure below shows the sub menu options for Settings:

8514-256-001 REV PR page 19

Usage Menu:

The Usage menu allows for the user to track data about machine usage. See below for
detailed information on each sub menu option.

1. “Coin Audit”: The coin audit field shows the accumulation of coin pulses that
were sent to the control over each of the left and right coin inputs. Note that this
is a count of coin pulses, not an accumulated report of vend value.

a. The user can also return the coin audit amounts to the factory default

setting (zero). To reset all coin audit values, press “Enter” when the
“DEFAULT” prompt is shown. Press “Enter” again when the “RESET”
prompt is shown to confirm the action.

2. “Cycle Count”: The cycle count field shows the accumulation of wash cycles that
have occurred. Note that this is a count of cycles, not of hours accumulated. The
user can also set the count value to a designated number. For example, if it is
necessary to replace the control on a machine, the new control could be
programmed to show the cycle count value that was recorded by the previously
installed control. The individual digits of the count can be set by using the “Up”
or “Down” buttons to change the number that is flashing. Once the desired digit
of the count is chosen, press the “Enter” button to move to the next digit. Once
the complete count is chosen, the “Enter” button must be held down for 3
seconds to confirm the action.

a. The user can also return the cycle count to the factory default setting

(zero). To reset the cycle count, press “Enter” when the “DEFAULT”
prompt is shown. Press “Enter” again when the “RESET” prompt is shown
to confirm the action.

3. “Motor Hours”: The motor hours field shows the accumulated hours of operation
for the motor. In many cases, it will match the cycle hours of the machine.
However, separate fields are provided in the event that a motor is replaced on a
machine. The user can set the motor hours to a designated number. For
example, if it is necessary to replace the control on a machine, the new control
could be programmed to show the motor hours that were recorded by the
previously installed control. The individual digits of the hours count can be set by
using the “Up” or “Down” buttons to change the number that is flashing. Once
the desired digit of the hours is chosen, press the “Enter” button to move to the
next digit. Once the complete hours are chosen, the “Enter” button must be held
down for 3 seconds to confirm the action.

WASHERS WITHOUT COIN ACCEPTORS

If you purchased a washer without a coin acceptor and are installing a payment device
of your choice, refer to the washer wiring diagram for proper connection. You may also
need to contact the payment device supplier for additional information.

RAPID ADVANCE MODE

Rapid Advance mode may be manually entered by pushing and holding the Cold water
temperature button and then pushing and holding the programming button on the
controller for three seconds. There will be no observed change to the washer or the
display. The Rapid Advance mode can be entered from either the Idle mode or during
the cycle. To rapid advance to the next step in the wash cycle, push the start button.
The display will show “ADVANCE”. The washer will advance to the next bath segment.
The water will drain before the advance will occur.

The Rapid Advance mode will not end until the final bath segment is completed. The
final segment cannot be skipped in Rapid Advance mode.

Notes: 1. When the Rapid Advance mode is used, the cycle time will no longer be

correct.

2. By skipping steps with rapid advance, the door may not open immediately at

The water level of all baths can be adjusted by changing the switch settings on the
electronic pressure sensor. Vended washers are shipped with the pressure sensor
harness connected to Switch #1 and factory set for an energy-efficient water level.
Switch #2 is factory set for the classic water level. To use Switch #2, move the org/yel
wire from the terminal marked 21 to the terminal marked 31 and move the red wire
from the terminal marked 22 to the terminal marked 32.

Water level adjustments can also be made in 1/4” increments by adjusting the switch
positions for the desired level. It is not recommended for the water level to be set
above the factory Switch #2 settings. Refer to the following chart for the switch
settings and the factory default settings:

VFD Over-

voltage Fault

Condition This error is over-voltage on the VF drive

Stop the machine and clear the cycle. Keep the door
locked until the machine has stopped moving and then
unlock the door.

Step 1: Measure the supply voltage to the VFD on the
L1, L2 (or N), and L3 (if connected to three phrase
power). The supply voltage should be from 187 to 264
VAC or 108 to 132 VAC for a 120 VAC VFD. Also make
sure the supply wires on L1, L2 (or N) and L3 (if
connected to three phase power) are securely
connected.
Step 2: Check the braking resistor connections at the
VFD. The terminal screws should be tight. One of the
braking resistor wires should be connected to terminal
B2.
Step 3: Measure each braking resistor separately to
make sure they are the correct resistance. (200 for 1,
2 and 3 Hp VFD and 160 for 5 Hp and higher VFD).
Step 4: If you have a 240 VAC, high leg voltage
supply, try disconnecting the high leg. If this cures the
problem, leave the high leg disconnected, connect a
transient voltage surge suppressor (with some form of
filtering) at the voltage supply panel, connect a line
choke on the high leg or install a VFD filter.

IMPORTANT

TRANSIENT VOLTAGE SURGE SUPPRESSORS

Like most electrical equipment your new machine can be damaged or have its life
shortened by voltage surges due to lightning strikes which are not covered by factory
warranty. Local power distribution problems also can be detrimental to the life of
electrical components. We recommend the installation of transient voltage surge
suppressors for your new equipment. These devices may be placed at the power
supply panel for the complete installation and don’t require an individual device for each
machine.

These surge protectors help to protect equipment from large spikes and also from small
ongoing spikes in the power that occur on a day to day basis. These smaller surges can
shorten overall life of electrical components of all types and cause their failure at a later
date. Although they can’t protect against all events, these protective devices have a
good reputation for significantly lengthening the useful life of electronic components.
Electronic components are helped to have a longer useful life when they are supplied
with the clean stable electrical power they like.

We are including the following names and phone numbers of a few suppliers of these
devices for those who don’t currently have a source.
