8. Combination use
8.1 Overview
The combination use of multiple ASE units can provide high flow with a system that requires high
flow.
The control of combined pumps for combination use operation is performed by the “master ASE”
unit, which allows combined “slave ASE” units following the master ASE unit to actualize the
same operation (at the same speed). Therefore, it is only the master ASE unit that receives
and processes pressure/flow commands and sequence signals. This mechanism can reduce
the load of the main system’s sequence signals.
For the combination use operation, the communication network is configured so that the entire
ASE system is urgently stop by the fail safe function when a failure occurs in a unit.
This control system is capable of controlling up to 16 combined units, or 3200-L/min flow
(ASE10- × 16 units).
The controller can be used for both combination and single use operation; the operation mode
can be switched by changing the settings.
8.2 Simplified diagram of the hydraulic circuit and wiring
- Directly connect all discharge lines.
- Only one pressure sensor mounted on the master ASE is used.
(No pressure sensor of the slave ASE units is used.)
- Sequence signals received by one unit for combination use operation are used for all combined
units.
