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.

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.

This product can be used in the following two types of configuration.

1.2.1 Standalone

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

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. The integral power consumption reset function is also available, which enables the
operator to analyze the peak power by only using the monitor unit.
