GIRBAU EH020 Operating Instructions Manual page 19

Drain valve: drain valve closes moment signal received and remains closed till the end
of programmed phase.
Water valves; as soon as door lock signals to micro that 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 thermistor 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 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 switch activates 3 times the cycle will end and display will
show "End – Bal"
Stop modes
•
End of cycle; when programmed cycle is finished the display shows "End" with
door open light on is considered normal
•
Interrupting a program; during a cycle operation the stop can be activated at
any time. Pressing the "Stop" key signals the control to turn off all power to
washers outputs allowing drain to open, door unlock time count down and all
other cycle functions to halt. Once the control times out and door is opened cycle
is terminated, if the door is not opened then press start key and cycle will resume
at the beginning of phase when stop key was pressed.
•
Emergency stop; pressing the E-Stop interrupts the washer operation similar to
interrupting the program. After a delay of approximately 3 minutes the door
unlocks.
Note: Be sure to open loading door prior to restoring power or door will relock as
soon as power is restored.
Other stopping modes
•
Turn off power at I/O switch on front of control panel
•
Turn off power at switch disconnector located on left rear of unit
