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 proportionally 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 or the totalizer will serve as the basis for the analog output signal. If the integrator/totalizer option is not installed, then this step defaults to “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” < > “-999” to “9999” for “INPUt” “-99999” to “999999” for “totAL”

ANALOG OUTPUT HI DISPLAY VALUE

Program the display value at which the analog output transmits 20 mA or

10 VDC.

“AN-HI” < > “-999” to “9999” for “INPUt” “-99999” to “999999” for “totAL”
