------ALARMS------
Controlled by:
Specifi es the binary value that selects the ON or OFF alarm limits.
When this value is OFF, the OFF alarm limits are selected; when it
is ON, the ON alarm limits are selected.
Alarm 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.)
Alarm Message # Low: ___ High: ___
Specifi es a pair of message numbers, one for LOW alarms and
the second for any HIGH alarms. These numbers are used by
the system to reference a message which is entered on the Alarm
Message Screen.
Alternate Limits Selected By:
Specifi es the point that initiates the Alternate mode. When this
address is zero (or OFF), the Normal alarm limits are selected;
when it is one (or ON), the Alternate alarm limits are selected.
Limits Low High
On _____ _____ °. F
Off _____ _____ °. F
On (alt) _____ _____ °. F
Off (alt) _____ _____ °. F
Local Set _____ _____ °. F
This group of inputs specifi es the alarm limits for the “Normal,”
“Alternate,” and “Local Set” modes. Each mode has a LOW and
HIGH limit. When the value of the analog input goes out of these
limits, an alarm is generated, and the alarm will automatically
display and e-mail out.
There are two fi elds on this screen that determine which set of
limits are active—the status of the “Controlled by” fi eld and the
status of the “Alternate Limits selected by” fi eld. When the value
that has been input in the “Controlled by” fi eld is ON, either the
“On” limits or the “On (Alt)” limits are active depending on the
status of the value input in the “Alternate Limits selected by” fi eld.
If the value in the “Alternate” fi eld is On, the “On (Alt)” limits are
used, and when the “Alternate” value is OFF, the “On” limits are
used.
Alternate Limits Active Alarm
Controlled by: Selected by: Limits:
On Off On
On On On (Alt)
Off Off Off
Off On Off (Alt)
The local set alarm limits become active if the MCD quits
communicating with the satellite controller. After communications
are re-established, any alarms that occurred while the satellite was
in local set will be reported.
Limit overlap time after control change:
This specifi es the amount of time the WCC software will wait after
a control change (i.e., on/off schedule, alternate mode, local set
mode) before deciding to generate an alarm. The fi rst input is a
user-entered number from 1 to 60, and the second input is either
seconds or minutes. This second input is a “choice” fi eld; the list
of available choices will be displayed at the bottom of the screen:
<Seconds, Minutes>
