1. Description of the control unit DFZ ZANOTTI s refrigerating groups are provided with a microprocessor electronic controller (cabin control) which automatically controls the operation. In particular, the electronic controller superintends the activation and deactivation of the diesel electric motor, in accordance with the preset temperature. The operation selection (diesel or electric) is automatically performed by connecting the plug to the mains. 1.1. Switching on the control unit To switch on the equipment press the first key on the right ( On/Off ) until the display is switched on. The same procedure should be performed to switch off the keyboard. After the presentation screen the unit state is displayed. Press the key to switch the refrigerating group on/off, while the display is lit. Standard Eletrical operation Diesel operation Multi-temperature n 2 Evaporators n 3 Evaporators 3
1.2. Diesel operation setting-up By pressing the key you can select the type of operation: Automatic (start/stop); the unit switches on/off in accordance with the preset temperat. (Setpoint). Continuous; the temperature is kept without switching off the motor. By pressing the key you can select high or low speed (only for the start/stop operation). ATTENTION The switching from diesel to electric is automatically performed any time the machine is connected to the electrical mains and is powered. If during the electrical operation a power failure occurs after about 5 minutes the machine restarts by diesel. 1.3. Setting-up of the operation set point To set up the operation set press the key, the screen will be displayed: Standard Press the keys to decrease or increase the value Multi-temperature n 2 Evaporators n 3 Evaporators Press the Press the Keys to move among the Set point (SP..) keys to decrease or increase the value. To return to the main screen press the key. 1.4. Evaporator enable and disable (only Multi-temperature Version) To enable or disable an evaporator press the key. To move to the side screen 4
By pressing the key you enter the evaporator s enable and disable screen. n 2 Evaporators n 3 Evaporators Through the keys, select the evaporator to be disabled or enabled and press the key to change its state. To return to the main screen press the key. The main screen will be displayed through a note which indicated the disabled evaporator. n 2 Evaporators n 3 Evaporators 1.5. Refrigerating group switching on Press the key to switch the refrigerating group on/off, while the display is lit. 1.6. Manual de-frosting From the main screen press the key for 5 seconds. The de-frosting activation is affected by the closure of the de-frosting end thermostat ( clixon ). During the de-frosting phase the icon will de displayed and simultaneously the key will start flashing. Once the de-frosting cycle is over the dipping phase starts with unit stopped and flashing display. 5
1.7. Alarms There are three types of alarm signalling: 1) Only display 2) Blockage with automatic restoring 3) Blockage with manual restoring 1) When an only display alarm occurs the icon is displayed on the main display to indicate the presence of an alarm as shown. The alarm is also signalled through the buzzers located on both the unit and the controller. Press once the key to deactivate the controller buzzer. Press again the key to display the type of alarm signalled. The icon indicates the alarm state, if the alarm is still active. To de-activate the buzzer of the unit press the key. To de-activate the display signalling, restoring the default state, press again the state. To return to the main screen press the Key. If the alarm automatically ceases the acoustical signalling is de-activated but the display signalling remains active, to reset enter the alarm screen and press the, key, to restore the default state. To return to the main screen press the key. 2) When an automatic restoring alarm occurs all that concerns the only display alarms is valid, but the refrigerating automatically stops and restarts if the alarm ceases. 3) When a manual restoring alarm occurs the icon and the Blocked wording are displayed. Also in this case the buzzers are activated. Press two times the key to access the screen where the type of alarm is signalled. When the cause of the alarms ceases. By pressing the key the no alarm screen is displayed The icon in the blocked state remains lit even when the alarm ceases. 6
Press the key to return to the main screen. When the alarm ceases press the Key to start the unit. 1.8.

Alarm description A01 Enviroment probe failure alarm This alarm causes the machine to stop permanently until the failure is repaired. To re-start the machine, you should reset alarm following procedure described in the above-mentioned paragraph and press the on/off key. A04/11 Pressostat alarm It occurs for a maximum or minimum pressostat intervention. The causes for the intervention of the maximum pressostat may be due to an inappropriate cleaning of the condenser or a slackening of the condenser fan belts, The intervention of the minimum pressostat may be due to Freon leakage. The intervention produces the machine stop until the alarm disappears. A05 Oil level alarm It is an only signalling alarm which does not affect the machine operation A06 Air filter alarm It is an only signalling alarm which does not affect the machine operation A07 Water temperature alarm It occurs when the radiator water temperature exceed the allowed value. It causes the diesel motor to stop. To restart the machine you should reset the alarm following the procedure described in the above-mentioned paragraph and press the on/off key. 7
A08 Open micro door alarm If occurs if the door of the motor room is opened. This alarm prevents the motor start. A09 Open door alarm It signals, if the micro-door is provided, the opening of the door of the load room. A10 Oil pressure alarm This alarm occurs in case the pressure of the motor oil drops; it causes the diesel motor to stop permanently. To restart the machine you should reset the alarm following the procedure described in the above-mentioned paragraph and press the on/off key. A12/13 Maximum/minimum temperature alarm It occurs if the actual cell temperature and the one set by the control differ beyond limit the preset on the factory. A14 Thermal relay alarm It occurs in case of anomalous current absorptions of the electrical motor and causes the machine to stop. To reset the alarm, activate the control unit, disconnect power from the machine, open the electrical panel and restore the thermal relay. Power the machine again, and press the on/off key located on the cabin control. A15 Low battery alarm If during the start/stop operation, when the machine stops as the preset temperature (set-point) has been reached, a battery voltage lower than 11 Volt for 10 seconds is detected, the re-start on continuous mode is forced. A16/17 Start failure/ alternator failure This alarm occurs if, when start attempts are completed (set in factory at 5) the diesel motor is not restarted. The causes may be: failed alternator, slackened belts, no fuel, blocked motor. If the same alarm occurs during the electrical operation the cause should be the alternator s inappropriate operation. To restart the machine just reset the alarm following the procedure described in the above-mentioned paragraph and press the on/off key. A18 Pre-heat water probe failure alarm It is an only signalling alarm which does not affect the machine operation. 1.10. Diesel operation de-activation (Motor blockage) To activate the blockage to the operation with diesel motor press the key for some seconds until the icon is displayed which indicates the impossibility of operation by diesel motor. Press the key to return to the main screen. 8
