SpectralLED® RS-7 USER MANUAL Page 67unit can send strings of its own volition at any time, asynchronous alarms may be disabled. Note that detectingan alarm condition in this mode requires that the user poll the unit regularly via the ALA command.Syntax:ASA 0 disable asynchronous alarms, operate in polled mode only (via ALA command).ASA 1 enable asynchronous alarmsExamples:asa0 disable asynchronous alarmsOk4.6.22 - CFC - Clear Fault ConditionIf the RS-7 encounters a serious operational problem, such as corrupted data structures, invalid calibrationinformation, or an internal hardware failure, it will enter a fault mode which none of the commands willfunction; instead, a fault message such as?F1 - initialization faultwill be the only response to any command issued to the RS-7.The three exceptions are the commands CFC, ICK (Integrity Check), and RST (Restart). Issuing CFC to the RS-7 willclear the fault condition and once again allow the unit to accept commands; however, continuing to operate theunit after having to clear a fault condition means it may not be functioning properly and cannot be trusted foraccuracy.Syntax:CFC clear fault conditionExamples:pre12 attempt to load preset #12?F1 - initialization fault command not accepted, unit is in fault modeout request current output level?F1 - initialization fault command not accepted, unit is in fault moderst restart unit to see what errors occur during initializationCH14 ERROR/CALIBRATION DATA: CRC or structure error channel #14’s calibration appears corruptGamma Scientific RS-7Firmware Version 1.07Okpre12 attempt preset #12 again?F1 - initialization fault still won’t function because of the initialization errorcfc clear the fault conditionOkpre12 attempt preset #12 again
