INSTALLATION 2.4 Piping 2.4.1 Basic circuit Observe the following basic matters and set up a circuit by referring to the figures shown below to operate the product properly. • While the cylinder is stopped, make sure that both ends are pressurized (to prevent the piston rod from popping out when the cylinder starts moving). -
Page 17: Piping
SM-482241-A/2 2. INSTALLATION 2.4.2 Piping • Use pipes that are made of corrosion-resistant materials after the filter such as zinc-plated pipes, nylon tubes, and rubber tubes. • Use pipes with an effective cross-sectional area that allows the cylinder to achieve the predetermined piston speed. -

- Page 23 SM-482241-A/2 2. INSTALLATION Parallel connection Since the leakage current of a 2-wire type switch increases according to the number of connected units, check the input specifications of the programmable controller, which is a connected load, to determine the number of switches to connect. For the 2-wire type switch, the indicator may become dim or not light up. Although the leakage current of a 3-wire type switch increases according to the number of connected units, the leakage current is very small (10 μA or less) and can generally be ignored.
