2. Wiring

・ Wire the product cable separately from high-voltage or power lines. Placing them in the same wiring or

the same duct may cause induction, resulting in the product malfunction or damage.

・ Make sure that the I/O terminals are inserted or removed with the power turned OFF. Doing this with the

power ON may result in a malfunction.

・ When using the provided DC cable, connect a wire with white line to the power supply (24 VDC±3%),

and connect a wire without the line to 0 V.

・ Mounting a ferrite core can reduce noise affecting to or affected by other devices when supplying power

with the DC cable. When using the provided DC cable, wind the provided ferrite core as shown below.

3. Battery use

・ Do not mix new and old batteries, or ones of different types or manufacturers. Doing so may result in the

product malfunction.

・ Do not install batteries in wrong polarities.

・ Always attach the battery cover during use. OMRON cannot be responsible for the product performance,

if the batteries accidentally drop off the product due to the unattached battery cover.

vii

・ Remove the batteries when they are not used for a long time.

・ Used batteries remaining installed for a long time may leak and corrode in the product.

・ Do not disassemble or throw the battery into the fire.

・ When the battery level is low, the product may repeatedly restart. If this happens, replace the batteries

with new ones.

・ Use the AC adapter when operating the product through a network, since network connection rapidly

consumes batteries.

1. Product Overview

1. Product Overview

1.1 Features and Functions

(1) Portable Power Monitor for Easy Operation at Manufacturing Sites

The ZN-CTX21 Portable Power Monitor provides simplified wiring operation and measurement
of power consumption (converted values) without stopping lines. Power data acquisition at

operation sites now becomes easy, contributing to enhanced energy-saving efficiency.

(2) Network Connection

The measured values obtained from multiple Portable Power Monitor units can be acquired to
a PC connected to the units via LAN cable by using the PC software. The individual Portable

Power Monitors can be controlled from the PC to check or change their settings as well as
start/stop the recording. (Refer to "Station Utility User's Manual" for details.)

Online real-time control of the entire network is also possible from the PC by using Wave
Inspire ES, separately sold software.

(3) Recording to an SD Memory Card

The measured data can be recorded in the Portable Power Monitor. Up to approx. 6500 data

items* can be accumulated in the internal memory, which enables the monitor to continue data
recording even at an emergency network failure. The monitor allows its data accumulated in

the internal memory to be output to an SD memory card in CSV format without stopping
measurement. The data can be loaded and controlled on the PC.

* The internal memory can store the data continuously for approx. 105 minutes at the

standard recording interval (1 second). Use an SD memory card for longer time of
recording.

(4) Graph Display and Data Processing Software

The data output to an SD card or acquired to a PC through LAN connection can be displayed

in graphs or processed online by using the PC software. The data items in different periods
can be combined or data from multiple monitor units can be displayed simultaneously top to

bottom on the screen. (Refer to "Station Utility User's Manual" for details.)

1. Product Overview

(5) Alarm Output

Alarm output terminals are provided on the Portable Power Monitor. The alarm is output when
the integrated power value exceeds the upper limit. This feature provides 'visualization' of the

power limit, allowing the operator to quickly handle problems. (Available in the NORM and
HISPD measurement operation modes)

(6) Backup Batteries

This product provides an uninterruptible power supply consisting of two AAA batteries, which
prevents recording operation from being stopped even at an accidental power outage or
failure. Rechargeable nickel-metal hydride cells or alkaline dry cells can be used.

*1: Battery life depends on the measurement environment and conditions as well as the

battery type and performance.

(7) Auto-range Switch

The Portable Power Monitor provides two measurement ranges: Normal and Small for each
dedicated CT type. The monitor can automatically switch the measurement range to a
small-scale range when the measured power level becomes approx. 5% or below the rat ed

current. Highly precise low power level measurement is possible.

(8) High-speed Logging

The Portable Power Monitor can provide the dedicated mode for more detailed measurement

recording.

The measurement recording speed can be selected between 100ms at 50Hz or 83ms at 60Hz,
which facilitates detailed analysis of power consumption changes (When the measurement

mode is set to HISPD).

*2: Network functions cannot be used during high-speed logging.

1. Product Overview

HUB

Standalone

Portable Power Monitors can be operated standalone without connecting them to a network.
The measured data is recorded in the internal memory and can be loaded to a PC via an SD

card. The recorded data in an SD card can be displayed in graphs using SD Viewer ES or
Energy Viewer, software included in Station Utility. (Refer to "Station Utility User's Manual" for

the PC software details.)

1.2.2 Network Connection

Portable Power Monitors can be connected to a PC via LAN. The following operations are
available by using the PC software. (Refer to "Station Utility User's Manual" for the PC
software details.)

(1) Remote Setting and Operation from PC

Settings on Portable Power Monitors (except for IP address settings) and recording start/stop

operation can be controlled remotely from the PC by using the Station Utility (PC software )
setting tool.

(2) Measured Data Acquisition to PC

The measured data on Portable Power Monitors can be acquired to the PC using the Station
Utility (PC software) logging tool. The acquired data can be displayed in graphs offline on SD

Viewer ES or Energy Viewer included in Station Utility.

1.3 Easy Power Measurement

 The Portable Power Monitor displays the measured momentary power during the power

is ON.

 The monitor measures electric current values, which are then multiplied by a specified

voltage and power factor (the ratio of effective power) to convert them into power values.

 A long press of the SET/REC/STOP key measures and displays an integrated power

consumption.

 Another long press of the SET/REC/STOP key stops recording and the integrated power

value up to that moment is displayed as a record in the ranking from the highest to

lowest integrated power values. (Ranking Function)

 Up to 9 value records can be logged in the ranking. When the 10th record is added, the

lowest integrated power value is deleted.

 The ranking can be cleared using the CLEAR menu item.

4.4 Copying Setting Data for Multiple Monitor Units

The settings on multiple Portable Power Monitor units can be unified by using the same
setting data saved in an SD memory card. This is convenient especially when controlling

multiple monitor units using the same settings. Make necessary settings only on one unit
(through unit operation), save it in an SD memory card and then, restore it in other units. This
can greatly save the entire setting procedures, thus, minimizing setting errors.

5.4 Starting/Stopping Recording

5.4.1 Starting Recording

The unit starts recording power level when the SET/REC/STOP key is held (long press for

at least 3 seconds) in RUN mode or when the specified start time is reached. The "REC"
indication turns ON when recording starts.

The measured data is recorded and accumulated in the internal memory, and is output in a
CSV file to the SD memory card when the SET/REC/STOP key is pressed.

Important

・If recording starts with recorded data remaining in the internal memory, the remaining

recorded data is lost. To save the data, press the SET/REC/STOP key for less than 3
seconds to output the data to the SD card before recording. Recorded data remaining in

the internal memory is the result of the unit restarting after a power failure or a press of
the reset switch in midst of recording. This situation does not happen if recording is
correctly stopped.
To check for remaining data, press the ▽ or △ key in RUN mode to locate the display

in which the current time is shown at the lower row. Check its upper row, and if its value is

"0", then there is no data remaining in the internal memory.

・The unit cannot start recording while an error message is shown in the display. Remove

the error cause, and cancel the error status by holding the MODE key (3 seconds or
longer). Then, start recording.

Note
・The Power Startup REC Restoration (REREC) function automatically resumes recording (if

it is set to "ON") when the unit restarts after it was accidentally turned OFF during
recording.

・An SD memory card must be placed in the unit when the SET/REC/STOP key is pressed

for data output during recording or when recording is stopped. It is not necessarily the
case at the point when the unit starts recording.

・Disable the write protection of an SD memory card. If it is enabled, an error occurs when

the unit attempts to write data to the card (when the internal memory becomes full) and

recording stops.

・A shift to other mode is prohibited during recording.

5.4.2 Stopping Recording

The unit stops recording and outputs files to the SD memory card when the SET/REC/STOP
key is held (long press for at least 3 seconds) during recording ("REC" is ON) or when the

specified end time is reached. The "REC" indication turns OFF when recording stops.

Important

A write-enabled SD memory card must be inserted in the slot when stopping recording. If
a data output attempt fails, recording stops with the recorded data in the internal memory

retained and the error message is displayed. Hold the MODE key (3 seconds or longer) to
cancel the error status. Insert an SD memory card and output the recorded data file to the

card by pressing SET/REC/STOP key. Do not start recording before the data in the

5. Measurement and Recording (Unit Operation)

5-6

internal memory is written to the SD memory card. The data is discarded once the unit
starts recording.

5.5 SD Outputting File to SD Memory Card

Recorded data can be output to SD memory card files when any of the following cases
happen.

(a) The SET/REC/STOP is pressed (for less than 3 seconds) during recording. Recording in

the internal memory continues.

(b) The SET/REC/STOP key is held (for 3 seconds or longer) during recording. Recording in

the internal memory stops.

Refer to: 5.4.2 Stopping Recording

(c) The internal memory becomes full during recording. Recording in the internal memory

continues. (The recording mode must have been set to "Continue mode".)

Refer to :4.2.4 (4) Recording Mode (REC)

(d) The SET/REC/STOP key is pressed (for less than 3 seconds in RUN mode) during

non-recording process, when recorded data remains in the internal memory. This refers
to the case that the unit restarts after it is reset during recording due to a power failure or

other reason.

(e) The Power Startup REC Restoration function (REREC) is set to ON, and the unit

restarted after a power failure during recording. Recording will start automatically after
completion of file output. If a file output failed, an error occurs and recording will not

start.

Reference: 4.2.4 (33) Power Startup REC Restoration Function

5.6 Cancelling Retained Alarm

"ALM" turns ON when the integrated power value exceeds the upper limit threshold or the

alarm output is ON.

To cancel the retained alarm, hold the MODE key (for 3 seconds or longer).

A generated alarm will not be automatically cancelled even if the integrated power is reset

and the value falls short of the threshold by the integrated power reset setting (INTEG).

5.7 Display Turning OFF

The display may turn OFF during recording in RUN mode if the unit has not been operated

for 10 seconds. This suggests that the unit has entered SLEEP mode. Despite the screen
being turned OFF, recording still continues as long as the unit is in recording process.

To activate the display again, press any key. A key pressed when the display is turned OFF

only triggers the display to turn ON, regardless of its specific function assigned. To execute
