6. ELECTRONIC TRANSMITTER (-E)<br />
6.2.7.1 General<br />
The volume totalizer function in the angle-transmitter WT-MAG is available with a potentialfree<br />
pulse contact.<br />
The connection is supported only at 4-wire-units on the power supply at pins 6, 7.<br />
The pulse output is activated and selected by function F34 in the menu structure.<br />
Two different pulse rates can be selected. The lower pulse rate (higher solution) corresponds to the last (least<br />
significant) digit of the totalizer. The higher pulse rate (lower solution) corresponds to the last but one digit of<br />
the totalizer.<br />

· F34 -1 not active<br />
· F34 -2 last totalizer digit<br />
· F34 -3 last but one totalizer digit<br />
Special case : If Qmax is higher than 10000, the pulse rate is increased by factor 10 in both cases.That means:<br />
· F34 -2 last but one totalizer digit<br />
· F34 -3 third totalizer digit from the right<br />
