Siemens SITRANS F TRANSMAG 2, Operating Instructions Manual, Page: 70 / 126

When "Split value active" is selected, the output is active when the current level of the flow value
is within the lower sub-domain 0 to "Split value". In this case the output current is scaled to the
0 to "Split value" range. If the flow value exceeds this sub-domain, the output current is scaled
to the 0 to URV range.
Note
The relay contact is open in the "no function" setting.
• Signal type, menu item 4.3.2
You can set the function of the relay as follows in this menu item:

NOTICE
At high inductive loads, the digital output must be protected against transient overvoltage with
a suitable external recovery diode.
The electronic fuse is tripped in the event of overloading. The recovery time of the fuse is a few
minutes. The relay contact is open in the no-load state.
