8.6.1 Errors after an initialization run
Followingasuccessfulinitializationrun,onlythegreenLEDislit.
IftheredLEDisashing,thisindicatesanerrorfollowinganunsuccessfulinitializationrun.
Thersterrortooccurduringinitializationisshown.IfthegreenLEDislit,theunithadalready
beeninitializedbeforethecurrentinitializationrun.IfthegreenLEDisashing,theunithadnot
beensuccessfullyinitializedpreviously.
TheredLEDshowserrorsoccuringduringinitializationasfollows:
Errorcode1:
interval interval etc.
Errorcode2:
interval interval etc.
etc.upto...
Errorcode8:
interval interval
etc..
Followinganinitializationrun,theredLEDshowsonlyinitializationerrorsaslongasDIPswitch
12issetto1.Thisenablesacleardifferentiationbetweenerrorsoccuringduringinitialization
andthoseoccuringduringnormalpositioneroperation.SettingDIPswitch12from1backto0
permitstheredLEDtoshowanynormaloperationalerrorsinsteadofinitializationerrorswhich
mayhaveoccured.
