3181 REAGENT PROBE UP/DOWN ERROR T (aa,bb,cc) System Status (1) The mode changes to STOP. User Action (1) Contact Olympus Technical Support. Additional Information (1) An error occurs when the Reagent probe is moving up or down. Error codes (Decimal) T : Time sequence No. aa : 1 : Motor busy 2 : The reagent probe rotating motor is busy when operation starts 3 : The cuvette wheel rotating motor is busy when downward motion starts at the cuvette position 4 : The reagent refrigerator rotating motor is busy when downward motion starts at the reagent aspirate position 5 : The cuvette wheel stop position sensor(S57) turns off when downward motion starts at the cuvette position 6 : The reagent refrigerator rotation inside stop position sensor(S50) turns off when downward motion starts at the reagent aspirate position 7 : The reagent refrigerator rotation outside stop position sensor(S49) turns off when downward motion starts at the reagent aspirate position. 8 : The reagent probe cuvette sensor(S43) turns off when downward motion starts at the cuvette position 9 : The reagent probe reagent position sensor(S45) turns off when downward motion starts at the reagent aspirate position 10 : The reagent probe reagent position sensor(S44) turns off when downward motion starts at the cleaning position/pre-dilution position/DI exchange position.. 11 : The reagent probe upper position sensor(S46) turns off after moving up 12 : The reagent probe upper position sensor(S46) turns on after moving down 13 : The clash error sensor(S47) turns on after moving down. bb : Time table No. cc : Phase No.
