Transducer and Communications Wiring
The below connection diagrams show wiring for a 2 pump (duplex) system using a single transducer
connected to a single drive and also a single transducer connected to multiple drives (4-20mA Loop).
Alternately, a separate transducer can be connected to each drive.
The difference between the two diagrams is; with a single transducer to a single drive, the Lag drives
cannot become a Lead (+) drive if the Lead (+) drive is manually stopped, trips or malfunctions. A Lag drive
must receive a feedback signal (4-20mA Loop or separate) to become a Lead (+) drive for continuous
control of the system. Depending on transducer wiring,
see Note in Section 6, Macro 2 Group (MC2) for
parameter MC2-03 setting for Lag drives.
Utilize the standard H2 Drive Manual for wiring not related to the Lead/Lag operation (any additional I/O for
control and monitoring). Note the communications connection among all drives (S+ to S+ and S- to S-) and
verify the polarity is correct for communications.
Important:
Turn ON the terminating
resistor on the last drive in the network.
