Type 3: Boolean parameters used to simulate command buttons.
The Boolean parameters have a range of Yes/No.
Only the user performs the modification of the value.
These “Type 3” parameters are used to initiate an action. There are two possibilities:
A 1 – the user wants the UPS to start the action => the user sets the parameter to “Yes”.
2 – the UPS finishes the action => the UPS sets the parameter to “No”.
B 1 – the user wants the UPS to start the action => the user sets the parameter to “Yes”.
2 – the user wants to abort the action => the user sets the parameter to “No”.
The actions that can be performed using such software buttons are:
• Print the metering information.
• Print the last 256 events.
• Print the values of the parameters.
• Print all the information obtainable from the UPS.
Returning from the Edit mode
Normally ok button is used to return from the Edit mode.
Then the UPS will perform some validity tests on the new value.
If these tests are successful then the new value is saved and used.
If these tests fail the Edit mode is not exited.
The validity tests performed by the UPS are not exhaustive.
You should not rely exclusively on these tests.
Care should be taken when modifying the values of the parameters.
For all parameters except the LCD Contrast parameter the new value is saved and used
after the ok button was pressed.
In the case of the LCD Contrast parameter the new value is used immediately in order to
obtain a better visual feedback.
