Model UPM100, UPM101
Universal Power Monitor
<Initial Setup Operations>
This manual describes the parameter setting procedures, measured value display
procedures and measuring ranges. The explanations of user operations in this manual
assume the UPM100 or UPM101 has display function. Parameter settings on UPM100
or UPM101 without display function are made through RS-485 communication.

1. Front Panel and Its Functions
In the diagram below, the switch cover, which is attached to part A, is opened so that operation
keys (8) through (12) can be seen.

IMPORTANT
Pressing switch (12) resets all measured
values other than active energy,
apparent energy, regenerative energy
and reactive energy.
Inside the cover on part (A), there are only
DIP switches needed for communication
settings.
Available display lights are (2), (3), and (6),
as shown on right.
(1) Measured value display: During operations, measured values are displayed in this area. During
parameter settings, parameters and their settings are displayed here.
When an error occurs, the display shows the error message. (See “4.
Troubleshooting” in the Measured Value Display Operations User’s
Manual.)
(2) Communication light:
This light (green LED) turns on while communication is in progress.
(3) Power light:
This light (green LED) turns on while the power is on. If a communication
error occurs, this power light flashes (four times per second) until normal
status is restored.
(4) COS φ light:
This light turns on while the instantaneous power factor (optional
measuring function) is displayed.
(5) RST light:
This light (red LED) turns on while voltage and/or current values are
displayed. For example, the “S” light turns on while the S phase voltage
value is displayed with a three-phase 4-wire setup.
(6) Integrated pulse light: This light (green LED) flashes to match the pulse output when integrated
pulses of each power are being output.
(7) Unit light:
This light turns on as the unit corresponding to the measured value. For
example, if the measured value is **** kW, then “k” and “W” lights turn on.
(8) SET/ENT key:
This key is used to switch displays and enter parameter settings.
(9) Move key:
This key is used to change a phase when measured value is displayed or
to move the digit position (decimal point position) when setting a parameter.
(10) Up key:
This key is used to change the set value when setting a parameter.
Pressing this key increases the numeric value.
(11) Down key:
This key is used to change the set value when setting a parameter.
Pressing this key decreases the numeric value.
(12) Reset switch:
This switch restarts the UPM100. Pressing this switch resets
all measured values other than active energy, apparent energy,
regenerative energy and reactive energy.
2. Conventions Used in This Manual and Basic User Operations
2.1 Conventions Used in This Manual
The following operation keys appear in this manual:
is the <SET/ENT> key.
is the <Move> key.
is the <Up> key.
is the <Down> key.
2.2 Basic Operations
Measured Value Display
Parameter Setting Display
Display after Power-on
After the UPM100 is turned on, the station number (initial setting: 01)
appears for about 5 seconds and then the display is changed to the
measured value display.
<To change measured value display>
<To change to the parameter setting display>
Each time you press the <SET/ENT> key on the measured
value display, the measured value display changes in a set
sequence. After the final measured value is displayed, the
first measured value (active energy) is displayed again.
Hold the <SET/ENT> key down for about 3 seconds on the
measured value display to change to the parameter setting
display.
Press the <SET/ENT> key once on the parameter setting
display to display the “set value” for the parameter.
Press the <SET/ENT> key in the set value display to
display the “confirmation display” for the set value.
Press the <SET/ENT> key on the confirmation display to
enter the set value and display the next parameter.
The display changes to the measured value display if you
hold the <SET/ENT> key down for about 3 seconds on the
parameter setting display or do not press any key for about
5 minutes.
