Service Suggestions
F2
MAIN BROOM
motor amperometric
protection
I > ISC (parameter) for a
time inversely proportional
to the difference between
I and ISC
Main broom
operation
blocked
Check for debris blocking the main broom
correct rotation.
Check the main broom adjustment and the
current draw in normal use. Compare with
parameter ISC (max allowable current into the
main broom motor).
F3
RIGHT SIDE BROOM
motor amperometric
protection
I > 10A FOR T>30s or I >
20A for T>5s
Right side
broom operation
blocked
Check for debris blocking the right broom
correct rotation.
Check the right broom adjustment and the
current draw in normal use.
F4
LEFT SIDE BROOM
motor amperometric
protection
I > 10A FOR T>30s or I >
20A for T>5s
Left side broom
operation
blocked
Check for debris blocking the left broom correct
rotation.
Check the left broom adjustment and the current
draw in normal use.
F5
VACUUM SYSTEM
amperometric
protection
I > 20A for T>10s
Vacuum system
operation
blocked
Check for debris blocking correct rotation of the
vacuum system motor. Replace the vacuum
system motor.
F6
HOPPER LIFTING
PUMP amperometric
protection
I > 80A for T>10s
Hopper lifting
pump operation
blocked
Check the hopper hydraulic system, change the
pump motor.
F10
MAIN / SIDE BROOM
/ VACUUM SYSTEM
/ HOPPER RAISING
PUMP power section
damaged
Short circuit of MOSFET
or main broom current
reading circuit damaged
Broom / vacuum
system / water
pump operation
blocked
Check for a short circuit in one of the Main
Machine Controller main outputs: main broom,
side brooms, vacuum system, hydraulic pump
harnesses.
Substitute the Main Machine Controller.
F11
Functions stage high
temperature
Heat Sink Temperature.
Functions stage > 90°C
All power outputs
blocked
Check for dust in the electrical compartment or
inside the Main Machine Controller cover. Check
for proper tightening of the board fixing screws.
F12

Broom function
block
Check for any short circuit in the main broom
motor harness.
F13
RIGHT SIDE BROOM
output short circuit
I > 100A for 10µsec.
Broom function
block
Check for any short circuit in the right broom
motor harness.
F14
LEFT SIDE BROOM
output short circuit
I > 100A for 10µsec.
Broom function
block
Check for any short circuit in the left broom
motor harness.
F15
VACUUM SYSTEM
output short circuit
I > 150A for 20µsec.
Vacuum system
operation
blocked
Check for short circuits in the vacuum system
motor harness.
F16
HOPPER LIFTING
PUMP output short
circuit
I > 150A for 20µsec.
Hopper lifting
pump operation
blocked
Check for any short circuit in the hydraulic pump
motor harness.
