5.0 START-UP AND CONTROL PANEL
The control operating procedure is as follows:
1. With the unit Off, both PIDs are disabled.
2. When the unit is turned on after the settable pump - compressor delay (
A036
), the startup PID is enabled and generates a percentage request
that will be processed to activate the compressors.
3. If the request is sufficient, one compressor will be turned on.
4. Once the compressor is on, after a settable delay (
A026
), there is the switching to the PID control during operation.
5. When the operation controller requests the shutting down of the compressors, they can shut down.
6. Once the last compressor is off, the control starts again with the startup PID controller configured.
5.3.2 MENU DESCRIPTION
Regardless of the displayed screen, pressing the programming key accesses the password
entry screen which allows access to the main menu shown here to the side.
5.3.2.1 PASSWORD MANAGEMENT
The program has 3 different password levels:
1. Advanced user (maintenance): read only access to all parameters.
2. Service: read access to all parameters with the ability to edit some of them.
3. Manufacturer: read/write access to all parameters.
In the parameters screen, the access needed to edit the parameters is shown, always
with the same codes (M for manufacturer, S for Service). Here at the side is shown an
example.
Once the password is entered it will be maintained for 5 minutes from the last time a key was pressed and then the password will need to be re-
entered in order to access the parameters of the advanced functions. In the Log-Out menu, the password can be force entered without waiting
5 minutes.
5.3.2.2 SCREEN LOOPS AND LAYOUT
In each menu, the screens are organised into loops: the up and down buttons scroll all the screens in the same menu. The screens are organised
so that the down button (scrolling downwards) accesses the most frequent screens, while those that are used least (e.g. configuration) are
accessed by pressing the up button (scrolling upwards).
Parameters code
EKapt has a code for each individual parameter to clearly identify them. Only the parameters are coded and thus the values that can be accessed
in read/write mode that characterise how the unit operates. The read only values are not coded. Each parameter has a 4 digit code identified as
follows:
1
st
digit
2
nd
digit
3
rd
digit
4
th
digit
Main menu code
Secondary menu code
