13. Common Problems & Solutions Malfunction of ID & OD communication: Incorrect ID & OD jumper settingIncorrect ID & OD jumper setting Incorrect polarity of communication wireIncorrect polarity of communication wire JP7 is not shorted for the last IDJP7 is not shorted for the last ID No power supply for IDNo power supply for ID Incompatible of ID & OD program versionIncompatible of ID & OD program version ID or OD PCB is abnormalID or OD PCB is abnormal Communication wire is too long. Should not more than 1000mCommunication wire is too long. Should not more than 1000m

14. Precaution: Complete jumper setting before power on, if not the setting will not be changedComplete jumper setting before power on, if not the setting will not be changed Connect the communication wire before power on, don’t insert or pull out it when power onConnect the communication wire before power on, don’t insert or pull out it when power on Pull out the signal output slot when testingPull out the signal output slot when testing Ensure the pin and socket is corresponded when installing the PCBEnsure the pin and socket is corresponded when installing the PCB Incompatible of ID & OD program versionIncompatible of ID & OD program version Ensure the dip-switch setting is correctEnsure the dip-switch setting is correct Follow the regulations & instructions in IMFollow the regulations & instructions in IM
