only after the power supply is reset.
With systems in which the user program operates in accordance with the PC
cycle time, since there is some fluctuation in the PC cycle time, the system opera-
tion may not be consistent, and this should be born in mind when designing the
system.
S When making the connection, switch off the power to the NT20S and PC before
When screen data transmission is in screen units, if there is data other than
screen data, for example memory table or direct access changes, transmit this

S Do not use input functions such as PT touch switches for applications where
During work at the panel, take care to ensure that no metal scraps enter the unit.
Otherwise, the product may malfunction.
For the connection to the power supply terminal block, twisted wires of 2 mm
greater cross sectional area and M3.5 size crimp terminals must be used.
Tighten the screws on the terminal block to a torque of 0.8N·m.
Otherwise fire may occur.
S After connecting the communication cable, always secure it with the screws.
S The cable’s tensile load is 30 N. Do not subject it to loads greater than this.
Do not install the NT20S at sites subject to the following conditions.
Otherwise, the product may malfunction.
