GIRBAU EH020 Operating Instructions Manual page 26

Sequence of starting a program will vary depending on door lock type normally open on
models EH020, REM025, RMG033, 040 and 055. The RMG070 uses a normally closed
door lock
Start signal activated by operator with press of start key, signal is sent to door lock
starting locking process and drain valve causing valve to close.
Door lock normally open; after the lock has received a start signal, a 30 second delay
time is started. During this time the drum rotation and water inlet operate at short
impulses and door remains unlocked. Anytime during this period, the user can open and
close door up until it locks. At the end of the 30 seconds the door will lock and cycle time
starts.
Door lock normally closed; after lock has received a start signal the door locks within a
moment and cycle starts. Door remains locked until a signal is sent from control to
unlock.
Drain valve; drain valve closes the moment signal received and remains closed till the
end of programmed phase.
Water valves; as soon as door lock signals to control that the door is locked it powers
the water valves. These valves work independently of each other meaning when cold fill
valve has power the hot fill valve does not and vice versa, when hot fill valve has power
the cold does not.
Example: The program calls for 140f water, this signals control to open hot valve only
until the thermister temperature is satisfied. At that time the hot fill valve closes and the
cold valve opens. The washer will continue fill by alternating hot and cold valves until
level and temperature is reached.
This means that only the hot valve or cold valve is open at any given time never, at
same time.
Thermister; is a probe located under washer outer drum at its lowest point, just left of
center, where it will allow contact with water entering the washer drum. The temperature
of the water is sent from thermister to washer control and in turn the control activates fill
valve required to produce programmed temperature of wash bath.
Unbalance switch – EH soft mount models only
During washer operation the control monitors the drum movement as a safety
precaution. At any point during the wash or spin action of the drum and the drum has
excessive movement it can activate the unbalance switch causing the load to redistribute
and then retry operations. If the switch activates 3 times the cycle will end and display
will show "End – Bal".
