KF-50SX100/50SX100K/50SX100U RM-903 RM-903 RM-903 SELF DIAGNOSIS FUNCTION 1-1. LE-3 SELF DIAGNOSTIC SOFTWARE The identification of errors within the LE-3 chassis is triggered in one of two ways : - 1: Busy or 2: Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty.
KF-50SX100/50SX100K/50SX100U RM-903 RM-903 RM-903 1-2. ERROR DETECTION MONITOR Device acknowledge is used to check IIC errors. Each device is checked three times, if there is no acknowledge after every attempt, it will be regarded as an error. There are three step to check errors. 1.
