VI. 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 - if the unit has not been in “on” mode 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-P00
will automatically re-enter the chamber temperature readout mode. Note!!! This function is also activated
during the defrosting time, when the display shows the „dF” symbol. The temperature of the chamber
sensor can also be seen by pressing for 0,5 second, which will make the display show the chamber
temperature (without blinking) to automatically re-enter the displaying of the „dF” symbol mode after the
consecutive five seconds.
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 mall functions 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, 10 and 11), the dot signalling the compressor's operation
will be blinking. When the protection system preset time preset elapses, the dot 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-P00 will
make impossible for the compressor to be activated for the period as specified by the ‘c2’ parameter. If,
however, ‘c2’=0min, the protection time will last 60 seconds following any power failure.
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 the ‘c2’ parameter, following the compressor’s prior deactivation. This allows faster
compressor operation check.
9. The controller has been equipped with alarm features, providing information regarding sensor’s damage.
Depending on the sensor(s)’ status, the controller performance will be different.
