Version of Control

T o determine control version, apply power to machine. Control will display version of control (i.e., 1.15).

Language on Display (Version 1.15 and later ONLY)

To set a different language on the WE-8 display:

1. Turn key from RUN to PROGRAM.

2. Press “Auxiliary”, “2” and “9” to enter set-up mode.

3. English will display. Press “Advance” until desired language displays (French, Italian, Spanish and German).

4. Press “Enter” keypad.

5. Press “Enter” to advance through set-up mode.

6. Wait until information is saved.

7. Turn key from PROGRAM to RUN.

8. Display will read language chosen for all cycles.

Setup of the Chemical Hold Feature (Version 1.11 and later ONLY)

• At power up, verify that model is at least version 1.11. Refer to version of Control Section. Earlier versions do not have this chemical hold feature.

• Insert key into key switch and turn to Program.

NOTE: If chemical hold is off, then supplies 4 through 9 are controlled exactly like supplies 1 through 3. A switch closure/opening between pins 1 and 4 of the COIN header on the output board will have no effect.

Program Storing Mode

The WE-8 control is capable of 99 total Cycles. One cycle contains 1 or more steps.

One step is a function of the wash program (example: heat).

Choose between the following functions: Fill: To fill the machine with water. Wash: Wash action of the machine. Supply: To add detergent to the wash (liquid or

powder). Cooldown: Cool to programmed temperature. Heat: To heat the water. Soak: The wash will be soaked for a

programmed time and a programmed

temperature. Aux: A relay contact will close for a

programmed time. Spin: To spin the machine for a programmed

time and RPM. Drain: To drain the water from the machine.

• Push the Auxiliary key, the 2 key, and the 9 key in succession to enter System Program Mode.

• Push the Start key 10 times to arrive at the Chemical hold choice.

• Push the Add Cycle/Advance key to toggle the Chemical hold feature either Yes (on) or No (off).

• Push the Start key twice to save changes and exit System Program Mode.

• Turn key switch to Run.

NOTE: If chemical hold is on, then a switch closure/opening between pins 1 and 4 of the COIN header on the output board will control supplies 4 through 9. A closure will turn the programmed supply/ies on and count down the time for the supply to be on. An opening will turn the programmed supply/ies off and halt the time for the supply to be on.

Explanation of the Step Functions

Fill:

Choose between 4 water inlet configurations and 3water levels.

Water Inlet Configurations:

Cold: Only opens the cold water valve. Hot: Only opens the hot water valve. Warm: Opens the cold and hot water valves. Aux Fill: Opens an auxiliary water valve

if installed.

Water Levels:

Low: Low water level. Med: Medium water level. High: High water level.

The inlet configurations and the fill levels appear on the keypad, keys 1, 2, 3 and 8.

Example: Warm Low (time limit 5 minutes 30 seconds)

Be sure to select first the inlet configuration and then the water level.

Then you will be asked for the step time limit.

NOTE: If a fill error occurs, then machine has 2 minutes to finish filling. If after 2 minutes it has not finished filling, cycle is aborted.

temperature of water coming in to the machine during a fill step. This does not apply to “Aux Fill” step. The control will mix the hot and cold water inlet to the temperature programmed in the fill function. To fill in the temperature, select the water inlet type and the water level. Press the “Heat” button and the control will ask the temperature. In this way the water inlet type selected is of no use because the control will mix between the cold and hot water inlet to reach the temperature.

Example: Fill to low level and 95°F (step time limit: 5 minutes 30 seconds).

Overcurrent shut-off during deceleration

Regenerative overvoltage shut-off during acceleration

When the inverter output current reaches or exceeds approximately 200% of the rated current during acceleration, the protective circuit is activated to stop the inverter output.

When the inverter output current reaches or exceeds approximately 200% of the rated current during constant speed, the protective circuit is activated to stop the inverter output.

When the inverter output current reaches or exceeds approximately 200% of the rated current during deceleration (other than acceleration or constant speed), the protective circuit is activated to stop the inverter output.

If regenerative energy causes the inverter’s internal main circuit DC voltage to reach or exceed the specified value, the protective circuit is activated to stop the inverter output. It may also be activated by a surge voltage generated in the power supply system

Regenerative overvoltage shut-off during constant speed

Regenerative overvoltage shut-off during deceleration or stop

If regenerative energy causes the inverter’s internal main circuit DC voltage to reach or exceed the specified value, the protective circuit is activated to stop the inverter output. It may also be activated by a surge voltage generated in the power supply system.

Motor overload shutoff (electronic overcurrent protection)

The electronic overcurrent protection in the inverter detects motor overheat due to overload or reduced cooling capability due to overload or reduced cooling capability during constant-speed operation to stop the inverter output. When a multi-pole motor or two or more motors are run, provide a thermal relay in the output side of the inverter.

Inverter overload shutoff (electronic overcurrent protection)

If a current of more than 150% of the rated output current flows and overcurrent shut-off does not occur (200% or less) inverse-time characteristics cause the electronic overcurrent protection to be activated to stop the inverter output in order to protect the output transistors.

Note: Resetting the inverter initializes the internal heat integrating data of the electronic overcurrent protection.

Fin overheat If the cooling fin overheats, the overheat

sensor is actuated to stop the inverter output.

Verify that the AC drive’s parameters are correct.

• Check for too

high ambient temperature.

• Check for

cooling fin clogging

Output side ground fault overcurrent protection

This function stops the inverter output if

a ground fault overcurrent flows due to

a ground fault which occurred in the

inverter’s output (load) side. Use Pr. 249

“ground fault detection at start” to set

whether the protective function is to be

activated or not. (In the 400V class, the

protective function is always active.)

Check the motor cable insulation and connection for output short-circuit/ ground fault.

External thermal relay operation

If the external thermal relay designed

for motor overheat protection or the

internally mounted temperature relay in

the motor switches on (contacts open),

the inverter output is stopped. If the

relay contacts are reset automatically,

the inverter will not restart unless it is

reset. Stall

prevention

Output phase failure protection

The running frequency has fallen to 0

with stall prevention activated.

This function stops the inverter output if

one of the three phases (U, V, W) on the

inverter’s output side (load side) results

in open phase.

Fan fault For the inverter which contains a

cooling fan, FN appears on the

operation panel when the cooling fan

fails.

Check for motor overheating. Check to make sure the machine is loaded properly and that the load is balanced.

Check the motor for a “locked rotor” condition.

Check the wiring. Check the motor for a fault.

Stall prevention (overcurrent)

During acceleration–If a current of

more than 150% of the rated inverter

current flows in the motor this function

stops the increase in frequency until the

overload current reduces to prevent the

inverter from resulting in overcurrent

shut-off.

When the overload current has reduces

below 150%, this function increases the

frequency again.

During constant-speed operation–If a

current of more than 150%, this function

lowers the frequency again.

When the overload current has reduces

below 150%, this function increases the

frequency again.

During deceleration–If a current of

more than 150% of the rated inverter

current flows in the motor, this function

stops the decrease in frequency until the

overload current reduces to prevent the

inverter from resulting in overcurrent
