WVRC-8 Installation and Operation Manual
PROGRAMMING
Analog (metering) Setup
When “5” is selected from the PGM Menu, the analog (metering) calibration and alarm
selections are displayed.
Select “1” to calibrate any of the analog (metering) inputs for the desired value.
Selecting a “1” will produce the following prompt “Select Ch 1-8 followed by the
desired 4 digit value”. Enter the channel number, then the desired value.
NOTE:
The decimal point may be added and is not considered part of the four digits
Example:
To calibrate analog (metering) channel 1, enter 1, then enter the desired
four digit reading.
Example:
75.00 would be seventy-five; 750.0, seven hundred and fifty while 7500
would be seventy five hundred.
NOTE:
The correct value on the analog (metering) input MUST be present for several
seconds prior to entering program mode. Once program mode is entered, the analog
(metering) inputs are locked and changes made while in program mode will not be
read. If there is no signal on the input, an error message will be displayed.
Enter a “2” from the Analog Set-Up menu to establish alarm set points. Analog
(metering) input set points are set up using items 1 - 8, representing analog (metering)
inputs one thru eight.
Example:
If your reading is normally 7000 V, and you want it to alarm when the volt-
age drops below 6300 (-10%) or over 7350 (+ 5%), then enter 6300/7350.
Temperature alarm set points are set up in the analog (metering) “Alarms” menu sec-
tion. Item “9” sets the low and high set points. The entry is a four-digit number with
the first digit being the F or C designator. If the first digit is a “0” then the number is
assumed to be Fahrenheit. If the first digit is a “1” then Celsius is assumed.
