Function Electronic Board Error Codes - Clarke Focus II Micro Rider 26D Service Manual

FUNCTION ELECTRONIC BOARD ERROR CODES

The function electronic board indicates a series of alarms codes in case of malfunction of one or more systems, and in case of
abnormal conditions detected in the input signals.
The alarms are shown on the display (71) (except "F6") by 2 signs following each other: "AL" and "XX", where XX is the alarm code
(see the descriptions in the following tables).
Also, the alarms are repeated (in case of display malfunction) by the diagnostic LEDs (yellow and red) on the electronic board, as
described in the following tables.
Alarm Code =
No. of flashes
G2 EEPROM error
G3 General thermal protection
G4 Blown F2 fuse
G5 Wrong KEY sequence
G6 No signal from BATTERY CHARGER
G7 Undervoltage
Serial communication error with dashboard
G8
electronic board
G9 Battery voltage drop
Alarm Code =
No. of flashes
F2
BRUSH motor amperometric protection
F3 VACUUM SYSTEM amperometric protection
F4 DECK ACTUATOR position irregularity
F5 VACUUM SYSTEM power section damage
F6 PRESSURE SWITCH signal fault
F7 VACUUM SYSTEM output short circuit
F8 Function general relay fault
All "general" and "function" alarms, and their relevant effects remain until reset from KEY input. In case of simultaneous errors, the
one with greater priority is shown first (priority order is opposite to the number of flashes).
