    ４ INSTALLATION 4. INSTALLATION ４．１ Installation When installing a solenoid valve unit, never attempt to hold it ！ WARNING WARNING : : : : WARNING WARNING in position by means of the pipes connected to it. • Mount the solenoid valve by applying the mounting screws and/or mounting plate to the solenoid valve.
  • Page 25 4.1.3 In case of installing by means of DIN rail For W4G2 Series, you can change the manifold of direct mounting type to DIN rail mounting type. If not counted properly, dropping down of the manifold or damage to it may be caused, to which please pay your careful attention.
  • Page 26 ４ INSTALLATION ４．２ Wiring It is required to connect signal circuit with power line to make this model MW4G※ 2-T8G※ function. Erroneous connection cases not only malfunction but in some cases, vital transmission damage to this station including other related devices. Read and understand the content of each User’s manual for Sequencer and CC-Link system, product of Mitsubishi Denki Co., Ltd ., as well as reading this manual to accomplish correct wiring.
  • Page 27 ４ INSTALLATION 2) Wiring of Communication Line. When connecting the communication cable to this slave station, solder the DA (blue), DB (white), DG (yellow), and shield (SLD) lines to relevant terminals of the water-proof connector. Additionally, perform the 3rd grade or higher construction work on the FG terminal.
  • Page 28 ４ INSTALLATION 3) Insertion and removal of water-proof connector (1) Attach Make plug matched with receptacle guide and push it straight. (Since 5-key method is used, make the plug in contact with the receptacle and turn the plug to make the plug matched with the guide.) (2) Removal Turn the coupling nut 45°in the direction...
  • Page 29 ４ INSTALLATION (4) Pre-solder the core wires of the cable with the wire ends processed. Do not pre-solder core wires until the sheath part of the cable. Carefully perform the pre-soldering so that the finish status is smaller than the diameter of the contact hole and the core wires are soldered evenly.
  • Page 30 ４ INSTALLATION For the signal line, be sure to use the cable conforming to the CC-Link specification. ！ CAUTION: CAUTION: CAUTION: CAUTION: Always use a proper cable suitable for applicable cable packing diameter of the water-proof connector. For details, see the product catalog made by Mitsubishi Electric Engineering Corp.
  • Page 31 ４ INSTALLATION Power cable (4-pole for DC) Follow the steps below to connect the power cable to this product. ① After checking the safety, turn OFF the power supply to be connected to the slave station. ② Check the following pin assignments and connect the slave station power supply and valve power supply to the power cable.

    MAINTENANCE ５． MAINTENANCE ５．１ Disassembling and reassembling this product (slave station) Slave station(NM4G※2-T8G※) Loosen the fixing screws on DIN rail of retainer. Remove the hexagon socket bolts (2 bolts). Separate the serial transmission blocks and pull out the tie rod. Pass the serial transmission block through the tie rod and push it between the adjacent blocks without leaving any clearance and then connect.
  • Page 33 MAINTENANCE ５．２ Troubleshooting Troubleshooting should address the entire system rather than a particular slave station. This slave station unit has its LED indicators similar to those provided on a Mitsubishi remote I/O station. Looking at these indicators and the indicators on the master station unit, you can determine the cause and take corrective action.
