Precautions for Safe Use
1. When unpacking the Units, check carefully for any external scratches or other damage.
Also, shake the Units gently and check for any abnormal sound.
2. The PT must be installed in a control panel.
3. The mounting panel must be between 1.6 and 4.8 mm thick. Tighten the Mounting
Brackets evenly to a torque of between 0.5 and 0.6 N⋅m to maintain water and dust
resistance. Make sure the panel is not dirty or warped and that it is strong enough to hold
the Units.
4. Do not let metal particles enter the Units when preparing the panel.
5. Do not connect an AC power supply to the DC power input terminals.
6. Use a DC power supply with minimal voltage fluctuation that provides a stable output even
if the power supply input is interrupted for 10 ms. The DC power supply must also have
reinforced or double insulation.
Rated power supply voltage: 24 VDC (Allowable range: 20.4 to 27.6 VDC)
Capacity:
7. Do not perform a dielectric voltage test.
8. Use a twisted-pair cable with a cross-sectional area of at least 2 mm
power terminals and always use M3.5 crimp terminals. Tighten the terminal screws to a
torque of 0.8 N⋅m. Make sure the screws are properly tightened.
9. Ground the Unit correctly to prevent operational errors caused by noise.
10. Do not touch the surface of the circuit board or the components mounted on it with your
bare hands. Discharge any static electricity from your body before handling the board.
11. Confirm that the current capacity of the connected device is 250 mA or less before using
the 5-V power supply from pin 6 of the RS-232C connector. The 5-V output from the PT is
250 mA max. at 5 V ±5%.
12. Turn OFF the power supply before connecting or disconnecting cables.
13. Always tighten the connector screws after connecting communications cables.
14. The maximum tensile load for cables is 30 N. Do not apply loads greater than this.
15. Confirm the safety of the system before turning ON or OFF the power supply or before
pressing the reset button.
16. The whole system may stop depending on how the power supply is turned ON or OFF.
Turn ON or OFF the power supply according to the specified procedure.
17. After changing the settings of the DIP switch, always turn the power supply OFF and ON
or reset the PT.
18. Do not perform the following operations while the Memory Card is being accessed:
• Turning OFF the power supply to the PT
• Pressing the PT's reset switch
• Removing the Memory Card
19. To ensure system safety, incorporate a program that periodically calls PT operation bits
from the host side to check that the PT is properly operating.
20. Start actual system application only after sufficiently checking screen data, macros, and
the operation of the program in the host.
21. Do not press a touch switch with a force greater than 30 N.
22. Do not operate a touch switch using a screwdriver or other tool.
23. Confirm the safety of the system before pressing a touch switch.
24. Do not press touch switches consecutively without pausing in between. If touch switches
are pressed consecutively at high speed, the PT may not be able to detect the inputs.
Confirm that the PT has detected the input of a touch switch before pressing any other
touch switch.
25. Do not accidentally press touch switches when the backlight is not lit or when the display
does not appear. Confirm the safety of the system before pressing touch switches.
