This setting is used to select the output functionality of digital output
D1 and D2 (and optionally D5 and D6).
Following functions are available:
disabled – not negative – separated – signed – retransmit
The retransmit mode is often used when sinus / non-square wave
input signals are present (e.g. coil signals) that need to be transmitted
as robust square wave forms.
A scaled pulse* is sent when the
accumulated total has increased.
Indicates the sign of the flowrate
(positive = 0, negative = 1).
A scaled pulse* is sent when the
accumulated total has increased.
A scaled pulse* is sent when the
accumulated total has decreased.
A scaled pulse* is sent when the
accumulated total has increased or
decreased.
Indicates the direction of the pulse sent
on output D1.
(increase = 0, decrease = 1).
The unscaled incoming pulse from
signal A is retransmitted.
The unscaled incoming pulse from signal
B is retransmitted.
*: a scaled pulse is sent on the output every time the accumulated total has increased or decreased with the
AMOUNT set at SETUP 8.3. The duration of the pulse is configured by setting the WIDTH at SETUP 8.2.
The pulse width determines the time that the output will be active; in
other words the pulse duration. The pulse width is set in milliseconds
in the range 0.001 – 9.999 sec.
Value “zero” will disable the pulse output.
The pulse signal always has a 50% duty cycle, hence the minimum
time between the pulses is equal to the pulse width setting. If the
frequency should go out of range – when the flowrate increases for
example – an internal buffer will be used to “store the missed pulses”:
As soon as the flowrate slows down, the buffer will be “emptied”.
It might be that pulses will be missed due to a buffer-overflow or
power loss, so it is advised to program this setting within its range!
One pulse is generated every X-quantity measured. If for example
you want 100 pulses per gallon: do enter 0.01 GAL (this means one
pulse every 0.01 GAL, so 100 pulses per gallon).
After pressing PROG, the decimal point will be flashing. The decimal
position can be changed now by pressing the ▲-key.
3.3.10 EXPLANATION OF SETUP-MENU 9 - COMMUNICATION (OPTION)
The E115-P can optionally be equipped with a communication interface using the Modbus protocol
(Type CB/CH/CU). Please consult Appendix C for a more detailed explanation of the protocol, data
types and available registers.
This setting is used to set the baud rate and should match the speed
used on the communications bus.
The following communication speeds can be selected:
1200 – 2400 – 4800 – 9600 – 9600HP – 19200 – 38400
Communication speeds from 9600HP and upwards are more power
consuming. When used with battery power, it is advised to set the
speed at 9600 or lower.
This setting is used to configure the bus address of your device on the
communications bus. This address can vary from 001-247.
