54 19 LOGIC FAILURE #1 Error in logic: power supply
undervoltage or overvoltage
Alarm displayed at start-up or in standby; in these cases, the
error is very likely due to undervoltage, then it is advisable to
check:
A) Descendant pulse of the key input signal (below the
undervoltage threshold) due to external loads, such as the
starting of DC/DC converters, relays, contactors or
excitation of solenoids;
B) If there is no voltage transient on the power supply line
and the alarm is present each time the system is turned on,
the error is likely to be due to the internal hardware, then the
controller must be replaced.
55 18 LOGIC FAILURE #2 Error in logic: hardware problem This type of error is not related to external components, so if
present, replace the controller.
56 217 PUMP I NO ZERO Pump feedback current outside
the allowed range
This type of error is not related to external components, so if
present, replace the controller.
60 60 CAPACITOR
CHARGE
Power capacitors cannot be load A) An external load absorbs current and does not allow the
power capacitor circuit to be charged. Check if there are
lamps or DC-DC converters connected in parallel.
B) The charge resistance is open. Insert a power resistance
between the contacts of the line contactor:
If the alarm disappears, it means that the resistance inside
the controller is damaged.
C) The charging circuit inside the controller is faulty.
D) The controller power section has a problem.
61 250 THERMIC SENS. KO Controller thermal sensor
malfunction
This type of error is not related to external components, so if
present, replace the controller.
62 62 TH. PROTECTION Operation in thermal protection -
controller overheating Improve the cooling of the controller.
If the alarm is displayed when the controller is cold, the
possible causes are a failure in the thermal sensor or in the
logic board. In the latter case, the controller must be
replaced.
63 204 WAIT MOT.P STILL Waiting for the pump motor stop If the motor connected to -P is still running, wait until it has
fully stopped.
Otherwise, within 30 seconds the alarm "PUMP VMN NOT
OK” will appear.
Refer to the item "PUMP VMN NOT OK".
64 238 TILLER ERROR Dead-man circuit error Check wiring of CAN # 1 and CAN # 29 by means of a
voltmeter. If the status of these inputs is right, there might be
problem in the controller, which must be replaced.
65 65 MOTOR TEMPERAT. Drive motor overheating Check the reading of the thermal sensor inside the motor
(by reading the value of the parameter MOTOR
TEMPERATURE in the MOTOR menu reading in the
TESTER menu);
check the ohmic value of the sensor and the wiring.
If the sensor is operating correctly, improve the air-cooling of
the motor.
If the alarm is displayed when the motor is cold, the problem
is inside the controller, which must be replaced.
67 218 SENS MOT TEMP KO Motor thermal sensor
malfunction
Check the correct connection of the temperature sensor of
the motor.
If the current sensor is connected correctly, try replacing it.
If the problem persists, try replacing the controller.
68 222 SMART DRIVER KO Positive output for electric brake
damaged
A) It is recommended that the wiring be checked in order to
verify if the Smart driver output, CNB # 1, is short-circuited
with -Batt.
B) If, even after disconnecting the wire from the connector
pin, the output remains at low voltage, the problem is inside
the controller and the Smart Driver may be damaged.
The controller must be replaced
