Display
: Shows the process variable (
PV)
, the configuration parameter prompts and their
respective values/conditions.
Indicators A1 and A2
: signalize the occurrence of an alarm condition.
Key P
: Used to walk through the parameters in the menu cycles.
Increment key and
Decrement key
: Used to change parameter values.
Key
: Go back to the previous displayed parameter. This key changes its behavior starting to set
the decimal digit to set.
7. Start up
When the controller is powered up, its firmware version is displayed for 3 seconds, after which the
DA9602
starts normal operation, when the value of
PV
is displayed and the outputs are enabled.
Before the indicator is ready to be used in a given process, it requires some basic configuration,
consisting of assigning values to the parameters according to the desired behavior. The user shall
understand the importance of each parameter and determine a valid condition or a valid value for
each one of them.
The configuration parameters are grouped in levels according to their affinity. The 5 parameter
levels are:
1 – Operation
2 – Alarms
3 – Input
4 – Totalizer
5 – Calibration
The
“P”
key provides the access to the levels and to the parameters of these levels.
Keeping the
P
key pressed, at every 2 seconds, the indicator jumps from one level to another,
presenting the first parameter of each level:
Measurement PV
>>
>>
>>
>>
>>
PV
…
To enter a particular level, simply release the
P
key when the first parameter in that level is
displayed.
To walk through the parameters in a level, press the P key with short strokes. To go back to the
previous parameters, use the
Key.
The display alternates the presentation of the parameter prompt and its value. The parameter value
is displayed with a light blinking to differentiate it from the parameter prompt.
Depending on the level of parameter protection adopted, the parameter
precedes the first
parameter in the level where the protection is active. See section Protection configuration.
