ALARMS ON THE DISPLAY
1) ACC
"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
Motor thermal cutout tripped
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:
