10 Group PULSE/FREQUENCY OUTPUT Device Functions Proline Promass 80

PULSE VALUE
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
Use this function to define the flow at which a pulse is triggered. These pulses can be
totaled by an external totalizer, and the total flow quantity since measuring started can be
registered in this way.
User input:
5-digit floating-point number
Factory setting:
Depends on nominal diameter and country,
[value] [kg or lb] / pulse;
corresponding to the factory setting for the pulses value (see see Page 63 ff.)
! Note!
The appropriate unit is taken from the function group SYSTEM UNITS (see Page 8).
PULSE WIDTH
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
Use this function to enter the maximum pulse width of the output pulses.
User input:
0.5...2000 ms
Factory setting:
100 ms
Pulse output is always with the pulse width (B) entered in this function. The intervals
(P) between the individual pulses are automatically configured. However, they must at
least correspond to the pulse width (B = P).
A0001233
B = Pulse width entered (the illustration applies to positive pulses)
P = Intervals between the individual pulses
! Note!
When entering the pulse width, select a value that can still be processed by an external
totalizer (e.g. mechanical totalizer, PLC, etc.).
" Caution!
If the pulse number or frequency resulting from the pulse value entered, (see function
PULSE VALUE on Page 36), and from the current flow is too large to maintain the pulse
width selected (interval P is smaller than the pulse width B entered), a system error
message (pulse memory) is generated after buffering/balancing time.
