B.5.2 Multi-pump Mode 2 (A2-03 = 1)
For example, the IMM servo pump system consists of four pumps with the address set as 1#, 2#, 3# and 4#.
There are the follwoing three combinations:
•
Combination 1: 4-pump convergent ow
•
Combination 2: 2+2 combination for distributed ow control
The 1# pump is the master pump and is followed by the 2# slave pump. The 3# pump works as the master
pump and is followed by the 4# slave pump.
•
Combination 3: 3+1 combination for distributed ow control
The 1# pump is the master pump and is followed by the 3# and 4# slave pumps. The 2# slave pump switches
over to the master pump.
