ANALOG OUTPUT
8.7 FILTER
Stabilizes the analog output signal. The output value is updated 8 times a
second. This digital filter setting produces a more stable but less actual
reading. The filter principal is based on three input values: the filter level
(01-99), the last analog output value, and the last average value.
The higher the filter level, the longer the response time of a changed value.

5.5.10 MENU 9: PULSE OUTPUT
The “Pulse” menu configures the behavior of the digital output signals. As standard, one transistor
output is available (Type OT): D1. Its function is based on the mode selected at
9.1: PULSE OUTPUT >
MODE
.
Optionally, one relay output is available (Type OR): D5. Its output functionality corresponds to the
functionality of output D1.
The digital (transistor) output D1 has a maximum frequency of 500 Hz (scaled pulse output).
Make sure the output frequency of the optional digital (relay) output D5 does not exceed 0.5 Hz,
otherwise the relay lifetime and reliability will be reduced significantly.

PULSE OUTPUT
9.1 MODE
The following modes of operation are available for the digital outputs:
●
Disabled
: the output is switched off.
●
Scaled
: each time the accumulated total has increased with the Amount
set at
9.3: PULSE OUTPUT > AMOUNT
, a pulse will be sent on the output with
the Width set at
9.2: PULSE OUTPUT > WIDTH
.
●
Retransmit
: the unscaled incoming pulse from the flowmeter is
retransmitted on the output.
The Retransmit mode is often used when sinus / non-square wave input
signals are present (for example, coil signals) that need to be transmitted as
robust square wave forms. The max. frequency is 10kHz with 50% duty
cycle and a minimum on and off time of 50µs.
When
Retransmit
is selected, the menus
9.2: PULSE OUTPUT > WIDTH
and
9.3: PULSE OUTPUT > AMOUNT
will disappear.
