WCC3.EXE SCREEN DESCRIPTIONS
During Valve 2 modulation,
If the control input drops below _____ % for
more than stage time, Valve 2 will close and
Valve 1 will modulate.
This user input is a percentage, 0 – 100 (but less than the percent
where Valve 1 closed and Valve 2 started), for if the control input
drops below this value for longer than the amount of stage time,
then Valve 2 will close and Valve 1 will start Modulating.
If the control input exceeds _____ % for more
than stage time, Valve 1 will full open and
Valve 2 continue modulate.
This user input is a percentage, 0 – 100, for if the control input rises
above this value for longer than the amount of stage time, then
Valve 1 will fully open and Valve 2 will modulate.
During Valve 1 full open with valve 2 modulation,
If the control input drops below _____ % for
more than stage time, Valve 1 will close and
Valve 2 continue modulate.
This user input is a percentage, 0 – 100 (but less than the percent
where Valve 1 fully opened and Valve 2 was modulating), for if
the control input drops below this value for longer than the amount
of stage time, then Valve 1 will close and Valve 2 will continue to
modulate.
Range
The system has the capability of generating an alarm if the value
of this global analog is either inside or outside of the desired range.
If inside is selected, an alarm will be generated when the value of
the global analog is within the two limits specifi ed. If outside is
selected, an alarm will be generated if the value of the global is
outside of the limits specifi ed.
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:
Make your selection by pressing the until the desired
data pattern has been selected and then press .
Low Limit High limit
The Low and High Limits can be either an Address or a Value.
When you move the cursor to this fi eld, the word Address or Value
will appear. Since this is a choice fi eld, press the
until the desired choice appears and then press .
If you select “Value” as the choice for this fi eld, you can enter a
number which will serve as the alarm limit.
If you select “Address,” you can specify an address such as an
analog input or global analog to be used as the alarm limit.
Type
Specifi es the priority (or “importance”) level for any alarms
generated by this input. Alarm types range from one (highest
priority) to eight (lowest priority). The system displays and e-mails
higher priority alarms fi rst. (The fi rst fi ve alarm priorities (1-5)
have e-mail-out-on-alarm capabilities.)
Message #
Specifi es a message number which is used by the system to
reference a message which is entered on the Alarm Message
Screen.
