INSTALLATION GUIDE
INFORMATION REPORTING
The H81xx continually reports kWh or MWh, depending on the total accumulated
energy. A secondary display cycles through other parameters. The meter has two
modes of display operation, depending on the setting of the Display Data jumper
(J8) on the main circuit board. In Full Display mode, the meter cycles through all
parameters. In Plain Display mode, the meter cycles through only the first five
parameters as listed below:

ALARMS
The following messages remain on the lower display for the duration of an alarm
condition:
Message
Explanation
Phase loss
The voltage on one phase is less than 75% of the voltage on any other
phase. The displayed message indicates the problem phase.
Amps Over
The measured current is greater than 110% of the transformer range. The
display message indicates the problem phase.
Volts Over
Volts A-C, B-C, or A-C is greater than 660VAC.
†
The displayed message
indicates the problem phase.
†
The H8163 and H8167 are rated to 300VAC L-N, and the H8150 is rated to 132VAC L-N. Operation
above these levels will damage the device.

H8163 and H8167:
Set the Pulse Rate selection switch to the desired output rate
(kWh per pulse). Note that 0.1 is not valid for 1600A systems, and 0.1 and 0.25 are
not valid for 2400A systems.
11. Secure the meter cover shut using a padlock, wire tie, or other locking device.
12. Apply power to the meter.
13. Check the display. At initial power-up, the meter checks each phase, and, if the
phasing is correct, an OKAY message appears. If the phasing is incorrect, an error
message indicates which color leads are not connected properly. Disconnect
power before reconnecting leads.
14. Check power reading. Expected power is estimated as follows:
kW = Volts(L-L) * Amps * 1.732 * PF 1000
kW = horsepower * 0.746
15. To reset the kWh accumulator to zero, press and hold the two pushbuttons on the
inside of the meter cover for 10 seconds.
16. To reset the kW max. register, press and hold the two pushbuttons on the inside
of the meter cover for 5 seconds.
