3.05.00, PULSE OUTP (Pulse output)
3.05.01 FUNCTION Function of pulse output with the following options:
1) OFF: switched off, contact closed.
2) ACT FLOW: proportional with the actual volume flow.
3) CORR FLOW: proportional with the corrected volume flow.
4) F/R IND: forward/reverse flow indication. Contact closed for
forward flow, contact open for reverse flow .
5) VOS: proportinal with the velocity of sound (range defined in
function 3.01.11 and 3.01.12).
6) DIG OUTPUT: digital output.
7) BATCH OUTP: batch output indication, only available for the batch-
version. Contact closes at start of the batch and opens when the
batch is reached.
8) GAIN: gain of sensor amplifier, proportional with the signal level.
Range: 0...100 dBV.
9) AN INP 1: proportional with the signal on analog input 1, only
available for the converter functions CORR T and CORR T+P.
11) AN INP 2: proportional with the signal on analog input 2, only
available for the converter functions CORR T and CORR T+P.
3.05.02 DIRECTION Direction of pulse output, only availabe when ACT FLOW or
CORR FLOW is selected in function 3.05.01.
1) FORWARD: the pulse output will only be active when the flow is in
the forward flow direction as defined in function 3.01.10.
2) BOTH: the pulse output will be active in both flow directions
(forward and reverse), indicating both in the same range.
3.05.03 DIG OUTPUT Function of digital output, only available when DIG OUTPUT is
selected in function 3.05.01. The pulse output now acts as a digital
output and can be programmed for the following functions:
1) PATH ERR: measuring path error indication (contact open).
2) TOTAL ERR: totalizer error indication (contact open).
3) ALL ERR: indication of all errors (contact open).
4) AN INP ERR: analog input error indication (contact open).
5) OVERRANGE: overrange indication (contact open).
6) TRIP POINT: status output trips if actual flow (Q) goes over a set
limit (an hysteresis is build in). Set points can be set using function
3.05.04 and 3.05.05.
3.05.04 TRIP PNT 1 First trip point.
Range: 0...120% of Q
100%
.
3.05.05 TRIP PNT 2 Second trip point.
Range: 0...120% of Q
100%
.
3.05.06 TIME CONST Time constant of pulse output (Note: the time constant setting only
applies to actual flow and corrected flow!):
1) 25 ms (lowest value).
2) MASTER TC: time constant has the value set in function 3.01.04.
