Returning to Operator Level
To return to operator level from either ‘
FuLL’ or ‘Edit’ level, repeat entry of the
password and select ‘
OPEr’ on the ‘Goto’ display.
In ‘
Edit’ level, the controller will automatically return to operator level if no button is
pressed for 45 seconds.
Edit level
Edit level is used to set which parameters you can view and adjust in Operator level. It
also gives access to the ‘Promote’ feature, which allows you to select and add (‘Promote’)
up to twelve parameters into the Home display list, thereby giving simple access to
commonly used parameters.
Setting operator access to a parameter
First you must select
Edit level, as shown on the previous page.
Once in
Edit level, you select a list, or a parameter within a list, in the same way as
you would in Operator, or Full, level
−
that is to say, you move from list header to list
header by pressing
, and from parameter to parameter within each list using
.
However, in Edit level what is displayed is not the value of a selected parameter, but a
code representing that parameter’s availability in Operator level.
When you have selected the required parameter, use
and
buttons to set its
availability in Operator level.
There are four codes:
ALtr
ALtr Makes a parameter alterable in Operator level.
PrO
PrO
Promotes a parameter into the Home display list.
rEAd
rEAd Makes a parameter, or list header, read-only (it can be viewed but not altered).
HIdE
HIdE Hides a parameter, or list header.
For example:
Hiding or revealing a complete list
To hide a complete list of parameters, all you have to do is hide the list header. If a list
header is selected, only two selections are available:
rEAd and HIdE.
(It is not possible to hide the ‘
ACCS’ list, which always displays the code: ‘LiSt’.)
The parameter selected is Alarm 2, Full Scale Low
It will be alterable in Operator level
