Safety Precautions
WARNING
Do not use this device in an environment with conductive pollution, or with dry non-
conductive pollution which can become conductive due to condensation, etc. Otherwise,
problems such as tracking phenomena may damage parts, resulting in fire.
Make sure that the frame ground terminal is properly grounded (100 Ω max.) before
connecting the controller to the measurement target or to external control circuits.
Be sure to check that the device has been correctly wired before turning on the power.
Incorrect wiring of this device may cause device failure and also lead to a dangerous accident.
Before removing, mounting, or wiring the device, be sure to turn off the power to this device
and any connected devices. Otherwise, there is a danger of electric shock.
Do not touch electrically charged parts such as the power terminals. There is a danger of
electric shock.
Do not disassemble this device. There is a danger of electric shock or device failure.
To prevent electrical shock, the main unit of this product must be installed in a location that is
only accessible to people with appropriate knowledge about electrical safety. Install the main
unit inside a control panel that cannot be opened without the use of a key or tool.
Also, before touching electrically charged components such as the input terminal block for
AC power, be sure to turn off the power. After checking that the voltage has dropped, work
carefully to prevent electrical shock. Always keep the cover on the power input terminal
block. Otherwise, there is a danger of fire or electric shock.
CAUTION
Use this device within the operating ranges given in the specifications (for temperature,
humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Otherwise, there
is a danger of fire or device failure.
Wire this device correctly by using the wiring method, power, and installation method
specified in this user’s manual. Otherwise, there is a danger of fire, electric shock, or device
failure.
Do not allow wire clippings, metal shavings, water, etc., to enter the case of this device. There
is a danger of fire or device failure.
Firmly tighten the terminal screws to the torque listed in the specifications. Insufficient
tightening may cause fire or electric shock.
Do not use unused terminals as relay terminals. There is a danger of fire, electric shock, or
device failure.
If the lithium battery used in this device is packaged together with it (installed) and
transported by air or ship, be sure that it is transported in accordance with the IATA DGR/
IMDG Code.
Do not block the ventilation holes. There is a danger of fire or device failure.
iv
CAUTION
Do not operate the buttons or the touch panel with a sharp object (such as a mechanical
pencil tip, etc.). Doing so can cause device failure.
The frame ground terminal of this device is a functional ground. Ground the frame ground
terminal to suppress adverse effects from external noise. Otherwise, malfunction may result.
Be sure that the settings are correct for the sensor type. If the settings are incorrect, the
normal PV will not be measured correctly. In that case a dangerous situation such as constant
100 % control output could occur.

Chapter 1. Overview
1 - 1 Overview
The C7G multi-loop controller with multifunction display (hereafter also called simply "this device" or "C7G" or
"C7") can calculate diagnostic parameters, known collectively as the health index, that help to predict failure of other
equipment, in addition to calculations for PID (proportional, integral and derivative) control of process variables
such as temperature, pressure, flow rate, pH, and liquid level.
This product consists of a display unit with a 3.5-inch QVGA LCD touch panel, as well as a main unit capable of
controlling up to four loops with an input sampling cycle of 10 ms and an indication accuracy of ± 0.1 % FS.
The display unit and main unit can be installed separately for installation flexibility.
A wide variety of interfaces, including Ethernet, RS-485 serial communication, microSD memory card, micro USB
port, and 7 digital input/outputs are provided as standard features.
Setup, operation, and monitoring can be easily accomplished using the display unit and Smart Loader Package.
This controller is compliant with IEC directives and is CE marked.
