8-38.2 Troubleshooting First of all(1) Are power supplys of all using wireless units as master and slave turn on?(2) Are the settings of switches set correctly?(Operation mode switch, Communication channel switch, Unit No.switch, MODE switch)(3) Are wiring and connector connected correctly?(RS232C, RS485) When turn power supply onTrouble contents Cause TroubleshootingPower supply is OFF. Turn power supply on.No LED lights onPower supply voltage isdifferent.Check power supply. (12 to 24VDC)Slave is not registered. Register all slaves to use communicationat master.When operatingmode is set to“RUN”, ALARMlights. *1Routing setting is not set. For 1:1 topology with repeaters or 1:Ntopology, set the routing setting.At 1:1 topology,slave is registered,but when operatingmode is set to“RUN”, ALARMlights.MODE switch No.1 is setto ON. (1:N topologyavailable)Set MODE switch No.1 of master andslave to OFF.*1: When operating mode is set to “RUN” at the time of purchasing, ALARM always lights. Slave registration, setupTrouble contents Cause TroubleshootingOperating mode isn’t setto “SET”.Set operating mode to “SET” both masterand slave.MODE switch No.9 is setto ON.When No.9 is set to ON, it is the mode toinitialize. Be sure to set to OFF beforeregistration.After setting switches, itdoesn’t turn power supplyon again.Turn the power supply on again.orChange operating mode switch.(SET→RUN→SET) switch isn’tpressed continuously.Press switch of slavecontinuously (approx.3 sec).Same Unit No. is alreadyregistered at master.Register with another Unit No.orOverwrite.Another wireless unit isusing the same channel.Change communication channel.Executing serialcommunication or I/OcommunicationRemove communication connectorSlave registration isimpossible.Radio wave doesn’treach.Do on the table.Check antenna if it is mounted correctly ornot.Wireless unit thatwas registered asmaster or slaveisn’t used asanother master orslave.When changing wirelessunit such as changemaster and slave,initialization is necessary.Initialize it first and register again.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: info@ctiautomation.net
