i-BRUSH
SAFETY AND OPERATOR’S MANUAL
6
The i-BRUSH system should be mounted
close to the generator or motor. It should be
fitted to a metal wall using its strong magnetic
feet. Ensure the brush cables are routed,
fastened, and able to reach the brush con-
nectors in a satisfactory manner.
Make sure the i-BRUSH system is turned off
before making any connections to it.
Connect the temperature and humidity sensor
to the corresponding connector and “mount”
the sensor on one metal wall using its
magnetic feet.
Mount the i-BRUSH sensor equipped brushes
in the generator or motor and connect each
to one of the six brush cables (8-pin Squba
connector)
Mount the current transformer around one of
the high-power lines (100-800A) and connect
it to the transformer cable of the i-BRUSH
system (2-pin Squba connector).
Always turn off and secure the generator or
motor before mounting or dismounting
brushes or connecting or disconnecting the
i-BRUSH system! Please also follow other
grounding standard procedures.
INSTALLATION
Optional power feed
If power is available, the i-BRUSH system
can optionally be connected to a DC adapter
(5-12V DC, 0.5-2A). If that is the case, the
current transformer does not need to be used
and connected to the system.
Operation
During normal operation, the i-BRUSH
system will with an interval of a few minutes,
measure all brush parameters for all connected
brushes. It will also measure the temperature
and the humidity in the surrounding area.
These values will be stored and later uploaded
to the i-BRUSH server and made available to
the user. The upload will take place once or
more a day. The upload interval and the
measuring interval are both configurable
parameters in the user web interface.
The system runs on a rechargeable battery
that is charged through the current transfor-
mer input. It will start to charge already at
low load times. Without charging, the system
will run for 2-3 days on the battery.
To save power the system “sleeps” between
the measurement cycles only consuming very
little power.
