Precautions for Safe Use 4
4 Precautions for Safe Use
• When unpacking the PT and peripheral devices, check that they are not
damaged. Lightly shake the products to confirm that no abnormal sound
is made.
• Use a power supply with the following specifications for the PT, and for
supplying power to the emergency stop switch, enabling switch, function
switches, and station detection.
• For compliance with the EC Directives (Low Voltage Directive), use a
power supply with reinforced insulation. Reinforced insulation refers to
a single insulation method that is capable of providing the same level
of protection against electric shock as double insulation.
• Do not connect the power supply terminals to an AC power source.
• Do not perform a dielectric strength test.
• Insert a 3-A fuse immediately after the secondary output from the pow-
er supply.
• Use a DC power supply with minimal voltage fluctuation.
Rated power supply voltage: 24 VDC (Allowable range: 20.4 to
27.6 VDC), Capacity: 10 W min.
!WARNING
• Always ensure that personnel in charge properly perform installation, inspection,
and maintenance for the PT. “Personnel in charge” refers to individuals qualified and
responsible for ensuring safety during machine design, installation, operation, main-
tenance, and disposal.
• Ensure that installation and post-installation checks are performed by personnel in
charge who possess a thorough understanding of the machinery to be installed.
• Do not attempt to disassemble, repair, or modify the PT. Doing so may impair the
safety functions.
• Always connect the stop/emergency stop switch and enabling switch to safety cir-
cuits. Serious accidents may occur if connection is made to a PLC and there is a
malfunction. When using the function switches or switches on the touch panel, do
not create switches that may cause injury or damage property. Install a monitoring
circuit or other device in output signals that may result in serious accidents. Con-
struct the system so that switching of important operations is performed in devices
outside the PT.
• For devices and components connected to the PT that affect safety, use appropriate
products meeting the required safety level and safety category. System safety and
the appropriate safety category must be evaluated for the entire system. Consult a
certified third-party organization to determine the appropriate safety category.
• It is the user’s responsibility to ensure that system safety adheres to relevant stan-
dards.
• Connect the emergency stop switch, and enabling switch on the PT so that they
function according to stop category 0 or 1 described in IEC/EN 60204-1.
• Do not operate the PT on the floor or on a tabletop.
• There are two types of switches on the PT, a red one for use as an emergency stop
switch, and a gray one for use as a stop switch. Use each of these for its intended
purpose. When using a PT with a red emergency stop switch, attach the cable from
the system securely so it cannot be easily disconnected. When using a PT with a
gray stop switch in an application where the PT is detached from the system, make
sure that the emergency stop switch and the stop switch can be clearly distin-
guished.

xx
Precautions for Safe Use 4
• Always use a Class 2 power supply for compliance with UL standards.
A Class 2 power supply refers to one in which the current and voltage
levels of the product’s secondary output are both limited (100 VA
max.), and which has undergone and passed the necessary tests for
UL certification.
• Properly ground the PT to prevent malfunction due to noise.
• Never touch the electronic components or patterns on product boards
with your bare hands. Touch grounded metal to discharge any static elec-
tricity before handling the PT.
• When connecting the cable to the PT, make sure to secure the cable and
the PT. Do not pull on the cable with a force greater than 60 N.
• Thoroughly check the wiring before supplying power.
• Turn OFF the power supply to the PT before connecting or disconnecting
the cable.
• Be sure to tighten the connector screws after connecting the cable.
• The entire system may fail to operate depending on how the power supply
is turned ON or OFF. Follow specified procedures for turning the power
supply ON and OFF.
• Thoroughly confirm operation of screen data, macros, and host program-
ming before starting actual use.
• Do not perform the following operations while the Memory Card is being
accessed.
Turning OFF the power supply to the PT
Removing the Memory Card
Always follow specified procedures for removing the Memory Card.
• To ensure system safety, incorporate programming at the host to periodi-
cally accesses a RUN signal to confirm that the PT is operating properly.
• Press touch switches with a force of 30 N max.
• Confirm system safety before pressing touch switches.
• Use caution when pressing touch switches if there is no display shown or
if the touch switch backlight is not lit.
• The inputs may not be read properly if touch switches are pressed in rapid
succession. Confirm one input before proceeding with the next.
• Confirm that the created screen data is backed up in the CX-Designer
before initializing the screen data.
• When changing the password in the System Menu, do not reset the PT or
turn OFF the power supply until the write operation has been performed
(i.e., until the Write Button returns to normal). The screen may not func-
tion if the password is not properly saved.
