passed to 2# inverter through serial communication.
10.5.4 Application field
Applied in field such as conveyer belt, coiler, factory production line, food
chemistry etc.
10.6 Application to constant pressure water supply
10.6.1 Summary for constant pressure water supply board
This constant pressure water supply board (hearafter in 10.6 referenced as “the
board”) is constant pressure water supply controller for multiple pumps, and it has
to work with EDS1000 to control constant pressure water supply system for
multiple pumps effectively. This control system also has automatic control
function fixed inverter driving mode and board repetition driving mode.
No need for adjustor and controller which is necessary to original system. It is a
cheap system but has excellent function and reliable performance.It will make
working time of every pump equal by time switching function to restrain aging of
pump.
The board has eight node outputs, each of which can drive relay of AC250V. So
it is capable of driving 4 pumps at best.
10.6.2 Outer dimension
10.6.3 Connection between constant pressure water supply controller and
inverter
(1) Put outside
For inverter of 11KW below, put constant pressure water supply controller outside
the inverter. Constant pressure water supply controller is collected with the
inverter by cables, as shown in Fig.10-7:
