Constructor Menu
The constructor menu is of level 4, it is necessary then to insert the constructor level password in order to
see/modify the parameters in this branch. Besides it can be reached only from the machine in OFF status.
ConF ( CONFIGURATION Menu)
Hard (HARDWARE INPUTS/OUTPUTS Menu) )
PSd4 (CONSTRUCTOR Password)
This menu contains all the machine’s configuration parameters that decide its operation way and which
functions habilitating or inhibiting according to the constructor’s needs.
The CONFIGURATION menu contains a plant configuration “wizard” to set the number of circuits, the
presence of compressors or fans controlled through inverter, the number of compressors and respective
divisions, the number of fans and the number of safeties to be used.
HARDWARE menus contain all the parameters for adjustment of positions to which connecting the various
devices.
⋅
Compressors’ digital outputs position
⋅
Fans’ digital outputs position
⋅
Inverter position to be connected to analogue outputs
⋅
Alarms’ digital inputs/outputs position
Note: Adjusting the positions of alarm’s various inputs, their functionality is set as well. In fact an alarm is
enabled only if the parameter that identifies its physical position on the clamp is set and is different from zero.
If we do not want to use an alarm, just let the corresponding parameter in zero value.
The same management is used for outputs management, for example of alarm relays: if the parameters are equal
to zero, the controls of the relays are disabled.
Firmware and project versions
Press buttons UP and DOWN at the same time 2 s; later, press ENTER when the label InFo is shown.
The display will show in succession the information on the project and firmware versions of the controller, as
follows:
Project number <-> Project version <-> Project revision <->
Firmware number <-> Firmware version <-> Firmware revision.
To scroll the information, use buttons UP and DOWN. To go back to the application pages, press button ESC.
4.3 Conditioned visibility
The conditioned visibility allows to hide configuration parameters and status according to particular
configurations.
For example: if the kind of regulation is Neutral Zone, configuration parameters about Side Band will
automatically be hidden.
Another example: if you have set the controller in order to control a mono-circuit compressor pack, all
configuration parameters about the second circuit will automatically be hidden.
In other words, all not relevant configuration parameters will not be shown by the user interface.
This function make easier the set up, the maintenance and the use of the controller.
During the configuration, once chosen the kind of compressor pack, not relevant configuration parameters will
not be accessible.
During the maintenance, you can test the device really present.
