PROGRAMS AND ELECTRICAL FUNCTIONS. WM 90A

PROGRAMS

1Normal wash with prewash

Prewash, long main, 3 rinses, short intermediate spin, 2 rinses and

long spin.

2Normal program

As program 1, but without prewash.

3Quick wash

Short main wash, 3 rinses, short spin, 2 rinses and long spin.

4Long spin

5Synthetic wash

Long main wash, 3 rinses and short spin.

6Synthetic wash

Long main wash, 3 rinses and short spin.

7Short spin

8Wool program

Short main wash, 3 rinses, short spin.

Gentle action and high water level.

9Pumping out

WM 90

PUSH BUTTONS

Main switch

Interupts the line (L1) and neutral connections.

No Spin

Omits the intermediate and the terminall spin. In programs 1-3 is

the water pumped out after the last rinse. In program 5, 6 and 8

the machine stops with the last rinse water in the cylinder.

Door opening

The door can be opened when the power is turned on, the water is

pumped out, and the timer is in one of the two positions, which are

marked with a dot.

Economy

Extends the main wash by 22 minutes.

Half load button

Omits the intermediate spin and two rinses in program 1-3. In

program 5 and 6 reduces one rinse.

800-button

Reduces spin speed to 800 rpm. With the button up, spin speed is

1000rpm.

Rinse level

In position you get high rinse level. In position you get

normal rinse level.

ELECTRICAL FUNCTIONS

Level controlled pumping out

Pumping out is made to the return level for the normal level, plus

additional 30 seconds, max. 1,5 minutes

Advantages:

*By installations with reduced drain flow, the pumping out is

prolonged to prevent the machine to go on washing with "old"

water" left in the machine.

* By normal drain flow there will be no noise by pumping of mixture

water-air.

Temperature block

In the wool program, the temperature Stop step has been maximized to 24

minutes. This means that if the temperature by mistake is set on, say 90°C,

the temperature still will not be higher than good 40°C (can vary a little

depending on the temperature of incoming water, the size of the load etc.).

In Whites wash/Cotton programs and in the synthetic programs the time for

the temperature stop is maximized to 80 min. This prevents among other

things the water to cook by broken thermostat (if the capillary tube is

broken) or that the machine goes on "for ever" by broken heater.

Out-of-balance-control by spin

The spin sequence consists of a short spin-up to 500 rpm, a so called

"peak", distribution and a longer spin. A tacho generator, placed on the

motor, measures the speed difference between the ”up-hill and down-hill”

before the spin. The greater the diffenrence, the greater the un-balance. If

the unbalance is too large, the spin is interrupted and the machine

distributes the washing and tries again.

By the peak maximal 9 start attempts are made,where the unbalance must

be below 0,8 kg for spin-up. If this is failed, additional max. 6 start attempts

are made with max 1,2 kg unbalance permitted.lf the unbalance is still too

high, machine will pass the spin step.

If the machine has made the ”peak”, the washing is distributed again,

start attempts to spin are made. Hereby max. 9 start attempts are made

with max. 0,7 kg permitted unbalance to reach 1000 rpm. After that further 6

start attempts are made on unbalance level 0,7 and 1,2 kg: If the unbalance

is less than 0,7 kg, the spin is made by 1000 rpm, if it is 0,7-1,2, the spin is

by 800 rpm.

If the unbalance is still too high, the machine passes the spin step.

ELECTRICAL COMPONENTS

1Timer

The timer has an electro-mechanical unit and an separate electronic unit.

The electronic unit controls the motor, the timer motor and some of the

program features.

The mechanical unit among others controls inlet valves, outlet pump and

heater.

2Thermostat

The temperature can be set stepless 0-90° C.

3Motor

The motor is an universal motor The rotation speed is stepless controlled

by a tacho generator on the motor which measures the rotation speed.

Maximal speed is 1000 rotations.

4Outlet pump

The outlet pump is combined with a integral button trap, which can be

cleaned by the customer.

5Inletvalve

The outlet pump is combined with a integral button trap, which can be

cleaned by the customer

6Heater element

1800 W heater element. Machines Singel-phase 16 A or 3-phase 10 A

do also have an 1200 W heater element Machines with heater contactor

have elements with fuse.

7Level switch

There are two level switches with two levels each :

• Normal level for wash. The return level ofthe normal ofthe normal level

is used to control the length of the pumping out and decides if the

machine shall spin or not, and cut out the heat.

• Normal level for rinse

• High level for Super rinse, wool programme and cool-down

• Overfllling level, breaks the current to the inlet valves and starts the

outlet pump.

ELECTRICAL COMPONENTS

8Contactor ( onlx 3-phase machines)

The heater contactor is controlled by the level switch, and interrupts the line

connections to the heaters.

9Door lock

The door lock is electric and the power must be turned on. The timer must also be

in one of the four positions for opening, on the scale. No water in the cylinder and

the cylinder must have stoped. Pressing the pushbutton operates a solenoid

which releases the door catch. The door can be opened in an emergency. By

inserting a screwdriver about 1 cm into the hole to the left of the glassdoor and

pressing upwards. A microswitch fitted beside the door-opening solenoid

interrupts the power supply to the machine when the door is open.

10 RFI suppression

RFI suppressions are fitted in accordance with international

requirements.

11 Wiring

The internal wiring in the machine is 1,5 mm2for heater connections, 1,0 mm2

or 18 AWG for earth connections and 0,5 mm2or 0,75 mm2for others.

12 Supply cord

The supply cord must be an RKK 3x1,5 mm2or 5x1,5 mm2cable

Wiring diagram and timer diagram are provided with the machine.

Power supgly alternatives

Poweralternative are:

1 phase, 230 V 10 A

1 phase, 230 V 16 A

3 phase, 400 V 10 A

The necary changes are made directly on the terminal block. See the

instructions.
