RATE PULSE OUTPUT CONNECTIONS
Connection of rate pulse output is simply a matter of connecting the
two field wiring terminals to the pulse input on the receiving
instrument and verifying that the K-factor is programmed into the
receiving instrument.
The simulated turbine output is not referenced to DC ground and is
not polarized, so wiring polarity is not important. See
Figure 1.9
.
The TTL output is referenced to DC ground and is polarized. When
using the TTL pulse, connect the plus (+) field terminal in the flow
meter to the frequency input on the receiving instrument. Connect
the negative (-) field terminal to the frequency input negative or DC
common connection in the receiving instrument. See
Figure 1.9
.
