(3) Connecting to droop
The switch is connected to terminals K and L. Signals indicating whether droop function works or not
serve as inputs to the controller by keeping K and L either open or close. Inputs can be done by toggle
or converting switches.
(4) Connecting to idle
The port on one side of the switch is connected to terminal M and the port on the other side to the
ground. Connection between terminal M and the ground becomes either open or close by keeping the
switch open or close. When connection between the terminal and the ground becomes close, the con-
troller will have idle function. Inputs can be done by toggle or converting switches.
(5) Connecting to aux
AUX is a terminal for control signal inputs from load sharing devices or synchronization devices
through terminal N. It shares load from the generator in parallel operation and receives signal inputs
from synchronization devices for the controller to control changes to load. Input signal level is between
DC -5 and 5 V and it is recommended to use shielded cables for signal wires.
(6) Connecting power to external devices
It can supply power output of 10 V/20 mA to external devices through terminal P. Users can easily use
this terminal when external auxiliary devices need power supply.
However, power supply of 20 mA or higher should not be used and care should be given to prevent
short circuits.
