However, if you change the CTs, you must restart the two-minute
initialization countdown by interrupting and then restoring power to
the recorder. If CTs on an operating Eagle recorder are
exchanged with CTs of a different type without re-initializing the
recorder, the unit will retain the setting of the first CTs as the
operating type. This may result in incorrect measurements. It is
also important to remember that if the CTs are not connected until
after the two-minute countdown has completed, the unit will not
detect that they are connected, and no accurate current
measurements will be taken.
Connecting to different types of services
When planning to connect your Eagle power quality recorder,
keep the following things in mind:
•
The banana jacks are color-coded by channel: Black is
Channel 1, Red is Channel 2, Blue is Channel 3, Yellow is
Channel 4, and White is common.
•
The unit is powered from the voltage between Channel 1
(Black jack) and common (White jack). For this reason,
even if you are not connecting all the input wires, Black
and White must be connected.
•
Be aware of the input voltage warning label on the
recorder. Do not exceed the maximum input voltage. The
limits are 600 volts RMS channel to channel or channel to
common for the Eagle recorders.
•
You may use four-channel units to monitor five-channel
systems, but you will record data for only four of the
channels. Conversely, you can use a four-channel unit to
monitor a single-phase system: either unplug the unused
leads, connect them in parallel so that all channels are
recording the same information, or clip together to avoid
noise readings. Again, Channel 1 must be connected in
order to power the unit.
