Siemens SITRANS F TRANSMAG 2 Operating Instructions Manual page 69

You can generate signals with positive and negative logic (positive and negative pulses). The
figure below illustrates the setting options.
• Pulse rate, menu item 4.2.3
The pulse valence indicates how many pulses are output per unit of volume or mass.
When the "Pulse" function is selected, you have to set the number of pulses per unit of volume
or mass.
• Pulse width, menu item 4.2.4
You can determine the pulse/pause ratio of the pulse output with the pulse width. The pulse
width can be set in a range from 0.1 to 2000 ms. A maximum pulse width is calculated in
relation to the set full scale value and the set pulse valence. The maximum pulse frequency
is 5 kHz.

• Full scale frequency, menu item 4.2.5
The frequency is permanently assigned to the flow. The pulse/pause ratio is constant 1:1. If
the "Full scale frequency" function is selected, the frequency is set in the range from 2 ...
10000 Hz.
Digital output 2 (Menu item 4.3)
The digital output 2 is available in device variants with the MLFB-No. 7ME5034-0xxxx-xxxx (Hart
communication and digital output). You have the following setting options in this menu:
• Function, menu item 4.3.1
You can configure the digital output 2 (relay contact) as an alarm or status output.
