WCC3.EXE SCREEN DESCRIPTIONS
WCC III Technical Guide 3-36
Sensor Type
This is a choice fi eld for Analog types only. A list of available
choices will be displayed at the bottom of the screen:
<General, Thermistor, Resistor,
Resistor+, RawCount, Thermistor+>
You may make your selection by pressing the <space bar> until
the desired Analog Type has been selected and then pressing
<Enter> .
Resistor is used to measure resistace of a variable potentiometer.
Available inputs are 0 to 9999 ohms,
NOTE: The associated analog input jumper on the satellite
controller must also be set to “THERM” in order for this
screen to display the proper temperature value.
Pattern for Values Associated With This Input:
Specifi es where you would like the decimal point to appear in the
value displayed by the system. Because this is a “choice” fi eld,
a list of available choices will be displayed at the bottom of the
screen:
< x,xxx , xxx.x , xx.xx , x.xxx >
You may make your selection by pressing the <space bar>
until the desired data pattern has been selected and then pressing
<Enter> .
Units of Measure Message #: 16
A number is entered here that references a message on the On/Off
Units Messages Screen. For example, if units-of-measure message
#16 is “Ohms,” entering “16” will cause “Ohms” to be displayed
as the units-of-measure for the analog input.
Filter Time Constant: ____ Seconds
Specifi es the sampling rate of the analog input. This is used by the
satellites to “fi lter” (or smooth) the analog input signal. This can be
used on inputs that “jump around” to reduce sporadic load control.
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:
< 0, 1, 2, 4, 8, 16, 32, 64 >
You may make your selection by pressing the <space bar> until
the desired fi lter time constant has been selected and then pressing
<Enter> .
Analog Input Resistor Screen
------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.
