Eliminating errors on the ABULiner

Only with Siemens frequency converter

In the event of malfunctions on the ABULiner:

Malfunctions on the ABULiner can be caused by the frequency converter. The frequency converter has three LEDs. Two of these light up or flash in the event of errors.

The brake of the hoist motor is wired such that, even in the event of an error, braking is ensured and the wire rope hoist stops.

LED for ready or malfunction

LED not used for ABULiner	LED for safety input

● The LED for ready or malfunction lights up green or flashes red.

● The LED for the safety input is lights up or flashes yellow (fast or slowly).

LED	Meaning
RDY (ready or malfunction) lights up green	No error has occurred.
RDY (ready or malfunction) flashes red	An error has occurred in the frequency converter.
SAFE (safety input) lights up yellow	Normal operating mode. The power unit of the frequency converter and the relay “release signal brake” are released. The main contactor is switched.
SAFE (safety input) flashes yellow slowly	The power unit of the frequency converter and the relay “release signal brake” are disabled. The main contactor is switched off.
SAFE (safety input) flashes yellow quickly	An error has occurred in the frequency converter or in the wiring of the safety inputs.

Only with the Schneider frequency converter

In the event of ATV340 frequency converter malfunctions:

Malfunctions on the ABULiner can be caused by the frequency converter. The frequency converter has numerous LEDs. Three of these light up or flash in the event of errors.

The brake of the hoist motor is wired such that, even in the event of an error, braking is ensured and the wire rope hoist stops.

LED for status	LED warning/error

LED not used for ABULiner		LED for safety function

● The LED for the status flashes or lights up green.

● The LED for warning/error lights up or flashes red.

● The "ASF" LED lights up yellow.

LED	Colour and status	Meaning
Status	Off	The frequency converter is switched off
	Flashes green	The frequency converter is not operating, but it is ready to start.
	Flashes green quickly	The frequency converter brakes or accelerates.
	Lights up green	The frequency converter is in operation.
Warning/ error	Flashes red slowly	Warning
	Lights up red	Fault
ASF	Lights up yellow	The safety function has been triggered.

In the event of ATV320 frequency converter malfunctions:

Malfunctions on the ABULiner can be caused by the frequency converter. The frequency converter has a display which shows the error codes.

The brake of the hoist motor is wired such that, even in the event of an error, braking is ensured and the wire rope hoist stops.

Display with error codes

● The display of the frequency converter shows an error code.

Error code	Meaning
STO	"Safe Torque Off" No mains voltage at the input Main contactor K 1.1 not tightened
RDY	"Ready" The frequency converter is ready for operation
CFF	"Incorrect configuration" Contact ABUS Service
CFI	"Missing configuration" Contact ABUS Service
OCF	"Overcurrent" Inertia or load too high, possibly due to mechanical blocking of the hoist motor. Check whether the brake opens correctly; reduce the load if necessary. If the error also occurs at zero load, check the hoist motor and contact ABUS Service.
ObF	"Energy surplus when braking" Excessive braking or driving load. During lowering: Check error LED on the power feedback unit.
OSF	"Overvoltage" Check the input phases.
USF	"Undervoltage" Check the input phases.
SCF1..3	"Short circuit or earth fault at the frequency converter output" Check the frequency converter output and motor connection. Strong leakage current against the protective conductor at the frequency converter output when connecting several motors.
NLP	"No voltage at the input"
NST	"Free runout" A control signal was present when the frequency converter started. Release the lifting/lowering and wait until the "RDY" frequency converter is displayed.

If there are malfunctions on the power feedback unit:

Malfunctions on the ABULiner can be caused by the power feedback unit. The power feedback unit has an LED which displays the operating status.


LED for status and error display

● The LED lights up or flashes red.

Status LED	Meaning
off	Device is switched off
on	Standby
flashes continuously	Device supplies energy
flashes 1 times	Input phase missing
flashes 2 times	Undervoltage
flashes 3 times	Excess temperature
flashes 4 times	Overvoltage
flashes 5 times	Overcurrent
flashes 6 times	Internal error

● After about one minute, the main contactor is automatically switched back on.

The LIS-SV is automatically reset after a few seconds (depending on the error). An error at the frequency converter is not reset this way. Usually, the emergency stop button should therefore be pressed to reset after an error. See Resetting after a malfunction.

Code	Reset after	Error	Possible cause	Eliminating the error
E_Fu	5 s	More than 15% more impulses from the encoder than permitted were counted in the limit switch range.	Hoist motor does not stop.	Contact ABUS Service. See ABUS Service.
			Control unit is defective.
		Impulses in the limit switch range can no longer be correctly counted.	The load hook was in the limit switch range when the parameter level was called up.
EFu1	13 s	With the “Lift” button pressed, the cable drum turned in the “Lower” direction.	Hoist motor is faulty.	Check the hoist motor.
			Error in the connection of the ABULiner.	Check connection. See Assignment of terminal blocks and pin multipoint connectors.
			The load slips through.	Contact ABUS Service. See ABUS Service.
		The cable drum turns in the “Lift” direction, but +12 V is not present at input I1..	Encoder is faulty.	Check encoder.
			Error in the connection of the ABULiner.	Check connection. See Assignment of terminal blocks and pin multipoint connectors.
EFu2	7 s	The permissible speed of the cable drum was exceeded by more than 20%.	Incorrect setting on the frequency converter.	Check parameters.
			Hoist motor is faulty.	Check the hoist motor.
			Error in speed analysis	Check the signals from the encoder.
				Check the parameters of the LIS-SV.
EFu4	67 s	Without the buttons “Lift/Lower” being pressed, a the switching of a brake contactor was detected (through input RxD on the LIS-SV)	Error in the connection of the ABULiner.	Check connection. See Assignment of terminal blocks and pin multipoint connectors.
				Check connection to brake contactor K26.3. See Assignment of terminal blocks and pin multipoint connectors.
EIMP	67 s	With the “Lift/Lower” button pressed, no impulses were received from the encoder.	Encoder is faulty.	Check encoder.
			The cable drum does not turn with the brake released.	Check connection. See Assignment of terminal blocks and pin multipoint connectors.
				Check the hoist motor.
			Connection cable of encoder is damaged.	Check the connection cable.
			The LIS-SV is faulty.	Contact ABUS Service. See ABUS Service.
(without)		No value can be set for parameter 5.11.	A value has been set for parameter 3.0.	Set parameter 3.0 to zero. See Activating/deactivating the LIS-SV for the ABULiner.
- - - - (bar in the display does not change)		A control signal (lift/lower) is present, the corresponding output is switched but the brake is not released.	Brake contactor K26.3 does not switch.	Check brake contactor K26.3 and activation. See Assignment of terminal blocks and pin multipoint connectors.
			Input RxD on the LIS-SV receives no signal.	Check connection. See Assignment of terminal blocks and pin multipoint connectors.
- - H2		With two wire rope hoists: Brake contactor K26.3 does not switch on wire rope hoist 2 (a signal is present at input I3 on the LIS-SV)	Error on wire rope hoist 2.	Check rope hoist 2. To check wire rope hoist 2, switch off joint operation (wire rope hoist 1 + 2) on the pendant control.

Backup limiter is travelled to.	Top hoist limiter is set incorrectly.	Readjust the top hoist limiter. See Setting switching points for backup limiter and top hoist limiter.
