Reading messages

Only for crane with LED matrix display and ABUControl

A message appears on the LED matrix display:


Fault code	Message

● The LED matrix display shows the fault code and the message from ABUControl as scrolling text.

The text speed can be set in KranOS by ABUControl.

See the ABUControl Product Manual.

Acknowledging messages

The displayed messages are divided into three categories, depending on their seriousness.


	Message category

● The category is displayed at the end of the message as “.1”, “.2” or “.3”.

─ “.3”: Information message. The crane can continue to be normally operated.

To acknowledge the message display, press the emergency stop button or horn.

─ “.2”: Not a serious error. The emergency stop function is triggered, the crane comes to a standstill.

To acknowledge the message display, press the emergency stop button or horn.

If the error does not occur again afterward, the crane can continue to be operated normally.

If the error occurs again afterward, the message is not displayed again. The crane can continue to be operated, however, the crane axis affected by the error can only be operated at slow travel speed.

─ “.1”: Serious error. The emergency stop function is triggered, the crane comes to a standstill.

To acknowledge the message display, press the emergency stop button or horn. If the error arose from a frequency converter, the crane must be switched completely off and then back on again.

If the error does not occur again afterward, the crane can continue to be operated normally.

If the error occurs again afterward, the message is displayed again. The emergency stop function is triggered again.

Assigning messages

The digits in front of the message indicate where (e.g. on which crane axis) the error occurred and which trolley or hoist (in the case of multiple trolleys on the crane) is affected.

	Third and fourth digits for the error number

Crane axis or operating range

─ First and second digits: number of the hoist, the trolley or the crane drive in combination with the crane axis or operating range

─ Third and fourth digits: error number

This results in the following combinations for the first two digits:

Digits	Location
F00_ _	General error
F11_ _	Hoist 1, hoist drive 1
F12_ _	Hoist 1, hoist drive 2 (only with twin hoist)
F21_ _	Hoist 2, hoist drive 1
F22_ _	Hoist 2, hoist drive 2 (only with twin hoist)
F31_ _	Hoist 3, hoist drive 1
F32_ _	Hoist 3, hoist drive 2 (only with twin hoist)
F13_ _	Trolley 1
F23_ _	Trolley 2
F33_ _	Trolley 3
F14_ _	Crane travel drive, frequency converter 1
F24_ _	Crane travel drive, frequency converter 2 (only with electronic track guidance system and 4-wheel crane travel drive)

“Hoist drive 2” (F_2_ _) is only used with twin hoists. All other hoists have only one hoist drive (F_1_ _)

“Hoist 2” and “Hoist 3” as well as “Trolley 2” and “Trolley 3” apply to cranes with two or three trolleys.

A crane normally has one frequency converter for both crane travel drives (F14_ _). For cranes with an electronic track guidance system, each of the two crane travel drives has its own frequency converter (F14_ _ and F24_ _). For 4-wheel crane travel drives with greater power consumption of the motors, the four drives can also be divided between two frequency converters.

Digits	Location
F40_ _	Crane distancing system
F41_ _	Bypass control
F51_ _	Trolley distancing system, Trolley 1
F52_ _	Trolley distancing system, Trolley 2
F53_ _	Trolley distancing system, Trolley 3
F60_ _	Overrun protection

Overview of messages

General information

“F0001: Standby.3”

The crane is switched on and in standby mode. To use the crane, unlock emergency stop button or log in transmitter.

“F_ _31 Hoist: Speed too high/low.1”

The actual speed of the hoist (measured by the absolute rotary encoder) exceeds the tolerance limits (too high/too low) as compared to the set speed of the hoist.

“F_ _32 or F_ _33 Hoist synchronisation: Deviation too great.1”

In the synchronisation control of two hoists for a crane with two hoists or with two cranes in tandem operation, the height difference between the two load hooks is too great when lifting or lowering.

Overview of messages for redundant travel limit switches and anti-collision devices

With a redundant travel limit switch, a crane distancing system, or trolley distancing system, two cross-type limit switches or light barriers are used on a switching point in order to additionally increase the level of safety. If both cross-type limit switches or light barriers do not simultaneously trigger when the switching point is run over, the corresponding message is displayed. Nevertheless, the crane or trolley brakes in accordance with the function.
