E-MON CLASS 3400 METER
IMPORTANT:
When looking from the source side of the conductor(s) being monitored,
you should see the arrow on the current sensor assembly. The arrow
should be pointing in a clockwise direction around the conductor(s) being
monitored. If the arrow is not positioned on the source side, inaccurate
readings will result.
6.4.2 Current Sensor Wiring
Once the current sensors are installed onto their appropriate phase conductors,
you can begin terminating the current sensors onto the E-Mon Class 3400 Meter
main board. The current sensors can be extended up to 500 feet for remote
monitoring applications. To extend the length of the wires, use #22 AWG twisted-
pair wire with one white and one black wire.
The easiest way to connect the current sensors is to use the meter's built-in
current sensor diagnostics. To do this, there must be at least 1% of the meter's
current rating (amps) flowing in each of the conductors being monitored. The E-
Mon Class 3400 Meter's diagnostic program will provide data to ensure that the
current sensor installation is done properly.
The current sensor connection points are located at the bottom right of the main
power board. These are terminals 5 through 10 of terminal block TB1. Each
sensor connects to two terminals one labeled "Black" and the other "White."
Current sensors should be connected to the meter one at a time and verified
using the current sensor diagnostic program.
Connect one of the current sensors to TB1 terminals 5 and 6 (Phase A). Wait 5
seconds and look at the meter display.
If the meter displays an error message (see below), remove the wires from
terminals 5 and 6 and install them on terminals 7 and 8 (Phase B). if an error
message occurs with the sensor attached to terminals 7 and 8, try again on
terminals 9 and 10 (Phase C).
The "CT Error:"msage will disappear when the current sensor is connected to the
correct terminals (phase).
Error Messages: CT ERROR: A
CT ERROR: A B
CT ERROR: A C
NOTE: The Single-Phase option will only display errors for A and B.
Refer to the section on Current Sensor Diagnostics for assistance in
troubleshooting these errors.
6.4.3 Main Power
After the meter circuit wiring has been examined for correctness, power may be
applied to the circuit board. There are three LEDs located in the upper right
corner of the Meter Board labeled BEAT, STATUS and LOAD. The BEAT and
STATUS LEDs will blink once per second when the meter is operating normally,
