4 ELECTRIC CONNECTION
4.1 Preliminary notes
The magnitude detected by the auxiliary sensor (terminals 5 and 8) can be set through the P4 configuration parameter as follows:
- no magnitude (parameter P4 = 0)
- condenser temperature (parameter P4 = 1)
- critical temperature (parameter P4 = 2)
- evaporator temperature 2 (parameter P4 = 3)
- outgoing air temperature (parameter P4 = 4); in this case, the temperature associated with the setting shall be the CPT
(Calculated Product Temperature) one
In the EVB1204N9 and EVB1214N9 models the application managed by the K4 digital output (terminals 13, 14 and 15) can be set by
the u11 configuration parameter as follows:
- room light (parameter u1 = 0, default setting)
- demister heating elements (parameter u1 = 1)
- auxiliary output (parameter u1 = 2)
- alarm output (parameter u1 = 3)
- door heating elements (parameter u1 = 4)
- neutral area operating heating elements(parameter u1 = 5)
- condenser fan (parameter u1 = 6)
- compressor 2 (parameter u1 = 7)
- defrosting 2 (parameter u1 = 8)
- evaporator fan 2 (parameter u1 = 9)
- pump down valve (parameter u1 = 10)
- on/stand-by (parameter u1 = 11)
- man in cold room exit (parameter u1 = 12).
In the remaining models, the application managed by the K5 digital output (terminals 16 and 17) can be set through the u1
configuration parameter and that managed by the K6 digital output (terminals 13, 14 and 15) through the u11 configuration parameter
as follows:
- demister heating elements (parameter u1 = 1)
- auxiliary output (parameter u1 and/or u11 = 2)
- alarm output (parameter u1 and/or u11 = 3, default setting for the K6 digital output
- door heating elements (parameter u1 and/or u11 = 4)
- neutral area operating heating elements(parameter u1 and/or u11 = 5)
- condenser fan (parameter u1 and/or u11 = 6, default setting for the K5 digital output)
- compressor 2 (parameter u1 and/or u11 = 7)
- defrosting2 (parameter u1 and/or u11 = 8)
- evaporator fan 2 (parameter u1 and/or u11 = 9)
- pump down valve (parameter u1 and/or u11 = 10)
- on/stand-by (parameter u1 and/or u11 = 11)
- man in cold room exit (parameter u1 and/or u11 = 12).
Through the RS-485 MODBUS port it is possible to carry out on eof the following actions:
- device configuration, through the Parameters Manager set-up software system
- device data recording, through the EVUSBREC01 data recording device
- device supervision, through the CloudEvolution system monitoring and supervision (via Web) system
- use of the MODBUS slave function through third party devices.
The port must not be used for more than one of these purposes at the same time.
Please see paragraph “Setting the configuration parameters” for the settings of the configuration parameters.
