PPUH „GECO” - G-202-P06 01, 02, 03 Program Version PRINTOUT DATED 2011-05-06
IV. OPERATION METHOD
A - General Information
1. Having turned the equipment on, the three-second starting procedure is activated, during which the
display will show two dashes, for the period of two seconds, and then for the period of one second,
the version of the controller program will be displayed, as well as two to dashes. No activation of the
equipment under control takes place then.
2. Following the completion of the starting procedure, two horizontal dashes signalling the energizing
status will light up on the central segments of the display -
before!!!. The unit will be activated after pressing the pushbutton . The display will show the
temperature value of the chamber sensor.
3. Having pressed and held down the pushbutton for the period of a half second, the display will
start blinking and showing the evaporator temperature, while after the consecutive five seconds, the
G-202 will automatically re-enter the chamber temperature readout mode. Note!!! This function is
dF
4. The compressor activation is signalled by the small red diode
in the right, bottom corner of the display showing the temperature. This allows easier check of
possible damage and malfunction to the system.
5. If the compressor should have turned on, but the compressor has not been turned on due to the
activation of any of the protection systems (see points 6, 7, and 8), the dot signalling the
compressor's operation will be blinking. When the protection system preset time preset elapses, the
daughter will stop blinking and will be lit permanently, while the compressor will be activated .
6. The delay in turning the compressor on after its activation temperature is reached (user set
temperature minus bottom value of the hysteresis) is equal to 30 seconds. If the temperature drops
again during this time. The condition of exceeding 30 seconds will be verified again. This is
designed to protect the compressor against unnecessary activation due to e.g. articles placement,
droughts, etc.
7. After every reaching of the preset temperature (user set temperature minus bottom value of the
hysteresis), as well as following any power failure or voltage drops below 175 volts, the G-202 will
ilure.
8. Having turned the equipment on using the pushbutton, the 5-second delay will appear in the
compressor activation. This is to cancel the power failure protection from point 7 this will also
pertain to the time specified by t
This allows faster compressor operation check.
9.
he controller performance will be different.
The malfunction of the chamber temperature sensor will make the display show the A1
symbol. The controller will activate the compressor in the time cycle (clock-based control) in
accordance with times specified
function as usual.
If the evaporator sensor is damaged, the display will show the A2 symbol. The manual and
automatic defrosting is blocked then!!! The only possibility of defrosting the unit is to
press the pushbutton in order to turn off the unit, and then wait for the ice to thaw.
The malfunction of the humidity sensor will make the display show the A3 symbol.
