7.1 operating Modes
The cooling unit operating mode control is executed by the vending ma-
chine controller. There are 4 modes of the cooling unit operation:
- Standby;
- Defrosting;
- Cooling;
- Anti-icing.
In each mode there are the cooling unit activation and deactivation, evapo-
rator fan activation, and deactivation, temperature sensors monitoring.
When activating the vending machine the cooling unit is switched to a
STANDBY
mode for two minutes. The further operation is taken place in ac-
cordance with the stabilized condition algorithm.
If when activating the vending machine the evaporator temperature (sensor
No.3) is lower than the evaporator temperature minimum value, the control-
ler is switched to
DEFROSTING
mode. When the temperature at this sensor
reaches the minimum value or higher, the cooling unit switches to
STANDBY
mode.
Standby
In the standby mode, the cooling unit is deactivated, the evaporator fan op-
erates in accordance with the user-defined mode, and the temperature sen-
sors are monitored.
If the temperature at sensor No.1 exceeds the value, specified in the (
Max.
temperature
) menu item, and the defrosting time is expired - the unit switches
to
COOLING
mode.
