5. MAINTENANCE
5.1 Removing the product (slave unit)
(1) After confirming safety, stop network communication as necessary and turn off all peripheral
equipment.
(2) After confirming safety, turn off the unit power and valve power as necessary.
Note that if there are other slave stations on the OUT side of this product, communication on the
OUT side will stop.
(3) Loosen DIN rail fixing screws. Using a needle-nosed tool, press and hold the connecting key
spanning the serial transmission unit block and adjacent blocks.
(4) While pressing and holding the connecting key, slide the serial transmission unit block along the
DIN rail in the direction so that block link port and connector are isolated.
(5) Turn up the block toward the piping port and remove the serial transmission unit block.
Verify that the power is turned off and then disconnect the power supply plug and communication
plug.
5.2 Mounting the product (slave unit)
(1) Set the slave node address and other switch settings.
(2) Turn off the power (for unit/valve) and connect the network plug and power plug.
The system may start operating suddenly if the plugs are connected while the power is turned on.
Be careful of the surroundings and secure safety before connecting the plugs.
Network plug: Reference tightening torque: 0.4 N·m
(Since it varies depending on the plug, consult the plug manufacturer.)
Power plug: Appropriate tightening torque: 0.2 to 0.25 N·m
(3) Slide the serial transmission unit block along the DIN rail in the direction so that adjacent blocks
are linked without leaving gap between them.
(4) Slide the retainer toward piping port until the claws catch the DIN rail and tighten the clamping
screws. (Recommended screw torque: 1.4 N･m.)
(5) Confirm safety and turn on each power..
