Precautions for Safe Use
10
Precautions for Safe Use
•
When unpacking the Units, check carefully for any external scratches or other
damage. Also, shake the Units gently and check for any abnormal sound.
•
The PT must be installed in a control panel.
•
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.
•
Do not let metal particles enter the Units when preparing the panel.
•
Do not connect an AC power supply to the DC power input terminals.
•
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:
NS15: 45 W min.
NS12, NS10, or NS8: 25 W min.
•
Do not perform a dielectric voltage test.
•
Use a twisted-pair cable with a cross-sectional area of at least 2 mm
2
to connect to the
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.
•
Ground the Unit correctly to prevent operational errors caused by noise.
•
Do not touch the surface of the circuit board or the components mounted on it you’re
your bare hands. Discharge any static electricity from your body before handling the
board.
•
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%.
•
Turn OFF the power supply before connecting or disconnecting cables.
•
Always tighten the connector screws after connecting communications cables.
•
The maximum tensile load for cables is 30 N. Do not apply loads greater than this.
•
Confirm the safety of the system before turning ON or OFF the power supply or before
pressing the reset button.
•
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.
•
After changing the settings of the DIP switch, always turn the power supply OFF and
ON or reset the PT.
•
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
•
Do not remove the Memory Card while power is being supplied to it. Always follow the
specified procedure when removing the Memory Card.
•
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.
•
Start actual system application only after sufficiently checking screen data, macros,
and the operation of the program in the host.
•
Do not press a touch switch with a force greater than 30 N.
•
Do not operate a touch switch using a screwdriver or other tool.
•
Confirm the safety of the system before pressing a touch switch. Do not press touch
