In the ANTI-FROST menu, it is possible to set the parameters connected with the thermal
regulation of resistors and control of the anti-frost alarm.
In the FREE-COOLING menu, it is possible to set the parameters connected with the enabling,
operation and activation of the free-cooling function.
The SAFETY DEVICES menu contains all parameters connected with alarms and management of
safety devices which protect the refrigerating circuit:
⋅
activations
⋅
reporting delays
⋅
type of resetting …
The VARIOUS PARAMETERS menu contains other general parameters connected with the
management of Modbus communications, transducer full-scale values and other configurable
activations.
The PARAMETER MAPS menu is accessible only with the machine in OFF mode. In this menu, it
is possible to re-establish factory-set parameters and to save or reload parameters from a
programming key. After each operation, it is necessary to switch OFF and then back ON the device.
Constructor Menu
The constructor menu is a Level 4 menu, i.e. it requires entering of the constructor level password,
in order to be able to display/modify the parameters contained in this branch. Furthermore, this
level is only accessible with the machine in OFF mode.
ConF (PLANT menu)
Hard (INPUT AND OUTPUT HARDWARE menu)
PSd4 (CONSTRUCTOR password)
This menu contains all the machine’s configuration parameters, which determine its operation mode
and which functionalities are to be enabled or disabled, according to the constructor’s requirements.
The PLANT menu contains a plant configuration wizard, which is used to set the number of circuits,
the number of compressors, the number of fans and the number of protection devices to be used
Once the configuration has been completed, a summary page is displayed, showing the configured
relays and digital inputs, with an indication of any need to use an expansion.
HARDWARE menus contain all parameters used for setting the positions to which the various
devices are to be connected.
⋅
Position of digital outputs of pumps, compressors and fans;
⋅
Position of inverter to be connected to analogue outputs;
⋅
Position of digital inputs/outputs of alarms.
Note: By setting the position of the various alarm inputs, their functionality is also enabled. Indeed,
an alarm is only enabled if the parameter which identifies its actual physical position on the
terminal has been set and is different from zero. If an alarm is not to be used, it is sufficient to leave
its corresponding parameter set to zero.
The same system is used to manage outputs, e.g. those of alarm relays: if position parameters have a
zero value, relay commands are disabled.
