•
BATCH OUTP batch output indication, contact closes at start of the batch and opens when the
batch is reached. Only available for the BATCH version (see Function 3.02.01)
•
SIGN GAIN, gain of sensor amplifier, proportional with the signal level, see Function 3.03.11
•
AN INP 1 proportional with the signal on analog input 1, see Function 3.02.01
•
FUNCTION, only available for the converter functions CORR T and CORR T + P (see Function
3.02.01)
•
AN INP 2 proportional with the signal on analog input 2, see Function 3.02.01 FUNCTION, only
available for the converter functions CORR T and CORR T + P (see Function 3.02.01)
Function 3.05.02 Direction of pulse output
Only available when ACT FLOW or CORR FLOW is selected in Function 3.05.01. When
FORWARD is selected, the pulse output will only be active when the flow is in the forward flow
direction as defined in Function 3.01.10 FLOW DIR, while when BOTH is selected, the pulse output
will be active in both flow directions.
Function 3.05.03 Function of digital status 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:
•
PATH ERR: measuring path error indication (contact open), see also the error message list in
Section 5.1: PATH 1 through 5
•
TOTAL ERR: Totalizer error indication (contact open),see also the error messages list in section
5.1: TOT > DISP and TOT CHKSUM
•
ALL ERR: indication of all errors (contact open),see also the error messages list in Section 5.1
•
AN INP ERR: analog input error indication (contact open), see also the error messages list in
Section 5.1: INP1 < MIN, INP1 > MAX, INP2 < MIN and INP2 > MAX
•
OVERRANGE: over range indication (contact open): CURR > MAX, FLOW > MAX and FREQ >
MAX see also the error messages listed in Section 5.1
•
TRIP POINT: Status output trips if the flow (Q) goes over a set value. An hysteresis is build in.
Set points can be set using function 3.05.04 and 3.05.05.
Function 3.05.04 through 3.05.05 trip point settings
Only available when TRIP POINT is selected in Function 3.05.03 DIG OUTPUT. These two settings
form a hysteresis. If PNT 1
Function 3.05.06 Time constant of pulse output
The time constant of the pulse output can be set to either 25 ms, which is the lowest value, or
MASTER TC, which will result in the value, set in Function 3.01.04 MASTER TC. The time constant
setting only applies to actual flow and corrected flow.
Function 3.05.07 pulse output function
The function of the pulse output can be set to either PULSE RATE (frequency) or PULSE/UNIT
(Totalizer pulse).
PULSE RATE: Is set by entering a frequency at 100 % volume flow rate
PULSE/UNIT: Is set by entering a value for the number of pulses for each volume (or energy) unit.
Each pulse having a fixed volume, i.e. 1 pulse / 0.1 liter. This is the best method of remote
totalizing, as pulses simply need to be counted, i.e. 10 pulses = 1 liter.
See Function 3.05.08 through 3.05.10.
Function 3.05.08 Pulse rate
If the function of 3.05.07 is set to pulse rate, the frequency of the pulse can be set that will be
available at 100% flow. The frequency can be set to: pulse/s, pulse/min, pulse/hr. The default
setting is 1000 pulses/second (Hz), the max setting is 2000.
