"drive lever" already pressed when the machine is turned on or after an Emergency 

2) SIC    

Emergency button pressed 

3) POT    

Speed potentiometer fault 

4) MOS    

Board (mosfet) short circuit 

5) HOT

6) LIM   

Board (mosfet) thermal limitation problem 

7) BLT   

Drive block. Appears when the battery voltage is too low and the drive is blocked.  

8) AcS   

Brush Control Fault Appears when there is a fault in the solenoid switch controlling 

the brushes.  
9) AcA   

Suction control fault. Appears when there is a fault in the solenoid switch controlling 

suction.  
10) FuP 

Fuse. Appears when the fuse is blown.  

 
 

Board alarms CLEANTIME 90/MICRO SCRUB 

 
If drive is interrupted, the error code should be identified by means of the status LED (fig. 6. ref. 16). 
In the absence of malfunctions, the status LED is steadily on while the machine is in operation.  If a 
malfunction is detected, the status LED provides two types of information, a slow flash (2 Hz) or a 
rapid flash (4 Hz) to indicate the severity of the malfunction.  
Malfunctions with a slow flash are cancelled automatically once the malfunction has been repaired 
and  the  machine  functions  normally  again.    Malfunctions  with  a  rapid  flash  ("*"  in  the  table)  are 
considered  more  serious.  The  machine  must  be  turned  of  using  the  key  switch  (fig.  6  ref.  14)  to 
reset operation after repairing the malfunction. 
The  indication  of  severity  remains  active  for  10  seconds,  after  which  the  status  LED  flashes 
constantly showing a two digit malfunction code until the repairs have been carried out.  
For example, error code "1,4" is displayed as follows:
