The return flow states the amount of product which the MultiFlow may
count in the reverse direction before an error message is output. A normal
value is eight liters.

The maximum error pulses
state the number of pulses
which are regarded as
erroneous. If this number is
exceeded, then a pulse error is
issued and the discharge
terminated.
Define the connected pulse
sensor by entering the sensor
type.
An NPN, PNP or THS sensor
can be connected. You can
determine the correct type of
sensor from the identification-plate on the flow meter.
Normally with a GMVT 703 or GMVZ 1003, a sensor type with a PNP
switching output is used. A THS sensor is used with the GMVT 704,
GMVT 805 and GMVZ 1004 measuring systems.
Error pulses are not evaluated if the actual flow is below ½ of the min.
flow rate. Additionally, after consecutive 30 seconds of too low a flow
rate, the delivery will be interrupted with a corresponding warning.
If the min. flow rate is set to 0, error pulses are evaluated in all cases,
deliveries will not be interrupted on min. flow.
