  2. 1. RAC Service tool COMT DMCT,CCCT

  3. 1. RAC Service tool 1-1 How to use DC motor checker (DMCT) (1) Connection （１）Choice a connector type To: DMCT To: CCCT Wiring (pin position )is different (Depend on FM model) （2）Connect FM to DMCT （3）Connect power cable To: DC MOTOR CCCT DMCT (Checker) Power cable

  4. 1. RAC Service tool 1-1 How to use DC motor checker (DMCT) (2)How to check （0）Before turn on the power supply ・Check motor rotation by hand ・Check wiring resistance （1)Turn on the power supply （2）Check voltage VM Vcc ・Vm – GND :330VDC ・Vｃｃ – GND :15VDC （3）Turn the Vsp controller clockwise ・Check FM rotating condition VSP volume controller Stable speed or fluctuated? Is there any noise? ⇒IF FM rotate normal, FM is OK

  5. 1. RAC Service tool 1-2 How to use Control circuit checker (CCCT) (1) Connection CCCT （１）Choice a connector type Wiring (pin position) is different (Depend on FM model) PWB Connector （2）Connect the wiring between CCCT and PWB No need a Power cable

  6. 1. RAC Service tool 1-2 How to use Control circuit checker (CCCT) (2)How to check （0）Before turn on the power supply ・Check fuse and varistor on PWB VM （1)Turn on a unit via remote controller Vcc （2）Check voltage ・Vm – GND :330VDC Vsp ・Vｃｃ – GND :15VDC Vfg （3）Check Vsp and Vfg ・Flashing (On and Off)? Flashing condition will be depend on FM control ⇒If yes, PWB is normal. This new version CE mark Self check DMCT-CCCT join and check all LED

  7. 1. RAC Service tool 1-3 How to use Communication checker (COMT) (1) Connection ② RAM data connector ① Serial cable (1,2/N,3) （１）ZE,ZG model We need to connect serial cable only （2）ZIX,ZJX model We need to connect serial cable and RAM data connector [SRC-ZIX]
