Page 10 Service Manual for Producers SCCB TYPE GC203
PPUH „GECO” EDITION I PRINTOUT DATE 2018-07-26
The maximal freezing time can not be exceeded, regardless of whether the evaporator has achieved the
temperature of ‘d5’, specified by the ‘c4’ parameter.
5. The procedure of exiting the defrosting mode is terminated with the activation of fans, turning off the „dF”
symbol on the display and turning off the green LED blinking on the pushbutton .
6. Should the fans be absent or not connected to the S.C.C.B. system, the unit will act as if they are installed.
7. The defrosting process will be terminated following the achieving of the evaporator temperature as preset in
the ‘d2’ parameters, or if the time preset by the ‘c1’ parameter has been exceeded.
8. Having turned off the „dF” symbol and terminated the defrosting process, the display will show the
temperature as stored right before the defrosting commencement, for the period of time as specified by the
‘c7’ parameter – this is intended for preventing claims with respect to “violent temperature fluctuations in
the unit”.
9. The unit performance is the same as in the case of manual and automatic defrosting.
10. The ‘r0’ parameter enables an override to turn the fan on during defrosting.
11. During defrosting there is no fan control based on the ‘d6’ parameter.
C – The Door Opening Sensor Operation Principle
1. If the door has been opened, the fan will be stopped immediately. In addition to the above, depending on
the ‘r7’ parameter setting, the light may be turned on in the GC203. The display shows the temperature. If
the reason of turning light on is door opening the diode on button is not turned on.
2. The door opening sensor can also turn on the light when the controller is turned off (two horizontal lines
on the display). The word "dr" will be displayed without an audible signal.
3. If the door has not been closed, after 30 seconds, the “dr” symbol will be constantly lit on the display and
the short lasting sound signal will be repeated every 30 seconds.
4. If the door continues to be open after the time as specified in the ‘r8’ parameter, the alarm will be
activated, which will be signalled by the display blinking with “dr” symbol, and with the sound signal if the
buzzer is installed. This is when the compressor will be turned off.
5. If the R8 = 0 the alarm will be activated immediately after opening the door.
6. The alarm may be silenced through pressing any button. Closing the door deactivates the alarm and normal
operation is resumed.
7. The controller allows to connect mechanical, magnetic of optical door open sensor (depends on version of
the controller). If parameter r6=01 sensor is connected in the course of door opening, if parameter r6=02
sensor is disconnected in the course of door opening.
