•
Because the 1# pump is always the master pump and the 2# pump alaways the slave pump, directly short
the DI terminal set for the 50# function.
•
The 3# pump switches over to the master pump in the following combination 2, which requires an external
switchover signal. When the host computer sends the closing signal, the DI terminal set for the 50#
function of the slave pump closes to process the multi-pump convergent ow.
