Indoor unit Indoor unit H-LINK Room Air- conditioner RAC adaptor RAC adaptor Indoor unit Indoor unit Outdoor unit Outdoor Outdoor unit unit CAUTION: – Turn OFF the power supply of the room air-conditioner of the central control device when performing the wiring work NOTE: – Consider the following points since the adhesiveness changes according to the environmental conditions (temperature, humidity etc) – The adhesiveness is decreased when there is humidity or oil. – Warm the adhesive part and installation place of the two-sided tape to avoid the decrease of the adhesiveness in case the ambient temperature is low. – DO NOT touch the adhesive part by fingers nor reattach it many times. The adhesiveness has decreased and the RAC adaptor may fall off. – DO NOT apply any force within 24 hours after installation. – DO NOT run all the H-LINK cable or power supply cable along the other signal cable, or malfunction may occur due to the noise, etc. If it is required to run along the other transmission cable, separate the cable more than 30cm, or run the cable through the metal tube and earth the tube. – Follow local codes and regulations when performing electrical wiring and earth wiring. – Transmissions cable used in H-LINK shall be 2 cores cable (0.7mm2 to 1.25mm2 for model: VCTF, VCT, CVV, MVVX, CVVX, VVR, VVF) or 2 cores twisted pair cable (model: KPEV, KPEV-Spec). Total length of cable shall be below 1000mm. – DO NOT use wire with more than 3 cores. Internal components and Wiring connections Check the contents and the number of the accessories in the packing. • Access Open the cover by removing the ① and ② screws. HITACHI PSC 6RAD • Wiring Connection Connection with Room Air-Conditioner i) Remove the front cover of the room airconditioner and the cover of electrical box. ii) The cable attached with the connector of the RAC adaptor shall be connected with the connector of indoor PCB OPTION LIST 32 iii) Install the electrical box cover paying attention not to clamp the cable. Read the installation manual of each room air-conditioner for confirming how to connect and how to assemble the cable of the RAC adaptor. CAUTION: – DO NOT turn ON various pins of DSW1 and DSW2 3) Set the refrigerant cycle# by RSW1 and DSW1 DSW1 (Ten digit) RSW1 (Last digit) CAUTION: – Disconnect the power plug before performing this work – ON OFF Turn OFF the break power source in case the power is supplied from the outdoor unit. • Connection of Transmission Cable H-LINK transmission cable connecting to RAC adaptor shall be connected to H-LINK. Use enclosed connector RAC Adaptor H-LINK wiring Connector (Accessory) RSW1 ON OFF The position is Set 5 No. 1 pin is OFF 4) Set the unit No. by RSW2 and DSW2 DSW2 (Ten digit) RSW2 (Last digit) Position ON OFF Band CAUTION: – DO NOT connect incorrect wiring. It may cause the failure of the RAC Adaptor. Especially pay attention not to apply high voltage e.g. AC400/230V. – DO NOT perform the wiring work while power to the central station or the RAC Adaptor is still being supplied. It may cause malfunction. Turn OFF devices when performing the wiring work. – The RAC Adaptor side cable should not overload to the connector. – DO NOT clamp the cable when attaching the RAC adaptor cover. – Band should not be loose and in fixed position. 10.2.4. DIP SWITCH SETTING 1) 2) Switch OFF the power of room air conditioner before setting the DIP switch. If the power is ON, the settings are INVALID. The position of the DIP switch is shown below. DSW1 (Refrigerant cycle# setting) DSW2 (Unit# setting) LED H-LINK transmission DSW3 Unit# setting LED E.g. Setting in Unit No. 15 RSW2 ON OFF No. 1 pin is OFF 5) The position is Set 5 Slave unit. In case of setting various RAC adaptors in the same refrigerant cycle, set the RAC adaptor with smallest Unit# as a master unit. In case of setting only one RAC adaptor in a refrigerant system, this adaptor should be a master unit. Set this procedure by DSW3. RSW1 (Refrigerant cycle# setting RSW1 DSW4 (Fuse recovery and terminal resistance setting Turn by using a screw driver DSW2 and RSW3 are set “0” before shipment. Up to 15 cycles can be set. PCB Unit# setting Turn by using a screw driver DSW1 and RSW1 are set “0” before shipment. Up to 15 cycles can be set. E.g. Setting in Ref No. 5 To other connection device of H-LINK Fixed position Position Master Unit setting ON Setting before shipping (slave unit setting) ON : Master Unit setting : Setting before Shipping (Slave Unit setting) OPTION LIST Indoor Unit# Refrigerant Unit# 7) 33 Terminating resistance is set in whole H-LINK system. a) If H-LINK connecting devices like package airconditioner are connected besides the RAC Adaptor, set the terminating resistance by those connecting devices. The terminating resistance should be set ON in only one position in whole HLINK system. b) In case that H-LINK is connected only by the RAC adaptor, set the terminating resistance by the RAC adaptor. The terminating resistance should be set ON in only one position in whole H-LINK system. PCB DSW4 CAUTION: – DO NOT set various main adaptors in the same refrigerant cycle. 6) Procedure when applying 200V voltage to H-LINK wiring incorrectly. In case of applying 200V voltage to H-LINK wiring incorrectly, the fuse installed in a transmission circuit on PCB will blow out. In this case, reconnect the wiring correctly and turn ON No. 2 pin of DSW4 on PCB. The transmission circuit can be recovered. (If applying this error again, the transmission circuit can not be recovered) PCB DSW4 ON 1 2 Turn ON No.2 pin of DSW4 ON 1 2 Turn ON No.1 pin of DSW4 10.2.5. TEST RUN Test run should be performed in the following after finishing the installation, wiring and setting. Refer to the installation manuals enclosed with the control system equipment. 1) Confirmation of RAC Adaptor Connection Confirm if the RAC adaptor connection is recognized in the control system equipments. In case that it is not confirmed, check the transmission cable, refrigerant cycle #, indoor unit #, terminal resistance setting etc. 2) Registration Confirm if the RAC adaptor connection is recognized. 3) Confirmation of RUN/STOP Operation. Confirm if the room air-conditioner operate correctly by RUN/STOP from the central control system equipments. Check also if the room air-conditioner operation changes correctly by each setting.
