Device Functions Proline t-mass 65 11 Group PULSE/FREQUENCY OUTPUT
Endress+Hauser 35
PULSE VALUE Use this function to define the flow at which a pulse is triggered.
These pulses can be totalled by an external totalizer, and the total flow quantity since
measuring started can be registered in this way.
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
User input:
5-digit floating-point number
Factory setting:
Depends on nominal diameter and country,
[value] [kg or lb] / impuls;
corresponds to the factory setting for the pulse value (see Page 71 ff.)
! Note!
The appropriate unit is taken from the group SYSTEM UNITS (see Page 9).
PULSE WIDTH Use this function to enter the maximum pulse width of the output pulses.
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
User input:
0.5 to 2000 ms
Factory setting:
100 ms
Pulse output is always with the pulse width (B) entered in this function.
The pauses (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 35), 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 mes-
sage is generated (#359 to 360, pulse buffer) after approx. 5 seconds buffer/balance time.
