Description

The Electronic Control System has the following characteristics:

  • Auto Start

  • Soft Start

  • Active Display

  • Lit Keypad

  • Total Hourmeter

  • Vehicle Compressor Hourmeter

  • Vehicle Compressor frequency depending on power available

  • Electric Standby Compressor Hourmeter

  • Low Battery Voltage Alarm

  • Buzzer

  • Unit Control without HMI

  • Manual or Automatic Defrost

  • Maintenance Warning

  • Return Air Temperature Sensor

  • Setpoint Temperature Reading

  • Electric Power Warning

  • Independent connection/disconnection of compartments in multi-temperature units

Auto Start: Should the unit stop due to a failure in the power supply, whether during on-the-road or electric standby operation, it will start up again as soon as the power supply is re-established.

Soft Start: All operation modes remain inactive for a few seconds after an Auto Start.

Active Display: The HMI display is always active and backlit except when the unit is disconnected (no power) or when the unit is connected but has been manually switched off from the HMI (when there is no active alarm).

Lit Keypad: The HMI keys are always lit except when the unit is disconnected (no power) or when the unit is connected but has been manually switched off from the HMI (when there is no active alarm). The On/Off key is always lit except when the unit is disconnected (no power), and thus indicates the presence of power in the unit.

Total Hourmeter: Total number of hours the unit is in operation.

Vehicle Compressor Hourmeter: Compressor hours in road mode.

Variable compressor frequency depending on power available: the controller will determine the optimal compressor speed in each situation depending on set-point, vehicle voltage and other parameters.

Electric Standby Compressor Hourmeter: Compressor hours in electrical standby mode.

Low Battery Voltage Alarm: Disconnects the unit when the battery voltage falls below 10.5V in 12VDC systems or below 21V in 24VDC systems.

Buzzer: It is energised when the vehicle battery and the electric power supply are connected at the same time. It is also energised if the doors are opened while the refrigeration unit is running.

Unit Control without HMI: The unit can also be operated by the Electronic Control System without the HMI, under conditions selected by the HMI before it is disconnected.

Manual or Automatic Defrost: It is possible to choose between manual or automatic defrost.

Maintenance Warning: On-screen warning of the need to carry out maintenance on the unit.

Return Air Temperature Sensor: On-screen reading of the temperature in the load compartment. In bi-temperature units, the temperature in both compartments can be read on the same screen.

Setpoint Temperature Reading: On-Screen Setpoint Temperature Reading. In bi-temperature units, the setpoint temperature of both compartments can be read on the same screen.

Electric Power Warning: On-screen warning that the unit is connected to an electric power supply.
