211 "COIL
SHORTED"
Init: Line contac-
tor and EB coil
driver protection
circuit is damaged
or Stby or running:
short on line con-
tactor or EB coil
PUMP • When the key is turned on, the micropro-
cessor checks that the line contactor coil
driver short circuit protection hardware If
it does not react in a correct way to the
micro processor stimulus, the fault is sig-
naled. When the fault that occurs while
the line contactor is closed this indicates
a short circuit across the line contactor
coil. check if there is an external short
circuit and if the ohmic value (xxx
Omhs) of the line contactor coil is cor-
rect
217 "WRONG
SET BAT-
TERY"
Battery voltage
does not corre-
spond to pro-
grammed "SET
BATTERY"
PUMP • This fault indicates that actual battery
voltage is 20% higher or 20% lower than
"SET BATTERY" parameter setting.
Replace battery with correct battery.
218 "SAFETY" Input F5 is not
connected to Batt-
PUMP xxx
222 "NO CAN
MSG"
Pump has lost Can
communication
with Master
PUMP • This Fault is present in combi Systems
(traction + Pump). The traction has
detected a fault and has informed the
pump controller through the can-bus line.
The pump is waiting for the traction ok.
The fault must be looked for in the trac-
tion controller or can-bus circuit.
225 "AUX OUT-
PUT KO"
(Not used)
EB coil driver
shorted or open
PUMP • The microprocessor checks the driver of
the electromechanical brake coil. If the
status of the driver output does not corre-
spond to the signal coming from the
microprocessor, the fault is signaled. It
is suggested to check for an external
short or a low impedance pull-down
between NHYDRO (F9) and -Batt.
