Return (PZR) Power Source
The PZR function allows the transmitter output to be forced to a zero
flow rate signal. While in this state, the transmitter will not react to
input changes. A zero flow rate signal appears until the PZR signal is
removed.
PZR is activated by an isolated external switch closure connecting
transmitter terminals 9 and 10.
To connect the PZR, complete the following steps.
1. Run the switch cable to the transmitter.
2. Connect switch leads to Terminal 9 and 10.
