PROGRAMMING MODULE #8 - PROGRAM RE-TRANSMITTED ANALOG OUTPUT
This programming module allows digital scaling of the 4 to 20 mA or 0 to 10
VDC analog output. The type of analog output is determined by the model
ordered. (See Ordering Information for available models.) The display value at
which 4 mA or 0 VDC and the display value at which 20 mA or 10 VDC are
transmitted are keyed-in. The indicator automatically calculates slope and
intercept values to complete the scaling. The analog output then follows the
calculated display value and as such will update every measurement cycle. The
output may also be programmed to re-transmit the contents of the totalizer
instead of the input. Reverse acting output can be achieved by programming the
“high”
display value for the
“AN-LO”
programming step and the
“low”
display
value for the
“AN-HI”
step.
Note: DO NOT ADJUST THE ANALOG OUTPUT POTS ON THE BACK OF
THE UNIT. Fine offset and span adjustment pots are externally accessible to
compensate for small drifts in the output. These pots have been set at the
factory and do not normally require adjustment.
ANALOG OUTPUT SOURCE
Program whether the input signal or the totalizer will serve as the basis for the
analog output signal. If the totalizer option is not installed, this step defaults to
the input.
“ASIN” < > “INPUt” or “totAL”
ANALOG OUTPUT LO DISPLAY VALUE
Program the display value at which the analog output transmits 4 mA or 0
VDC.
“AN-Lo” < > “-99999” to “999999”
ANALOG OUTPUT HI DISPLAY VALUE
Program the display value at which the analog output transmits 20 mA or 10
VDC.
“AN-HI” < > “-99999” to “999999”
Programming of the re-transmitted analog output signal is complete. The
indicator will return to
“Pro 0”
.
