indicates a situation which may result in minor or moderate injury.
---|---
WARNING
indicates a situation which may result in serious injury or death.| DANGER
indicates a situation that will result in serious injury or death.

General information

NOTICE
After installation and during the operation of the NGF system in connection with the crane system, additional hazards may occur. These hazards go beyond the framework of these mounting and wiring instructions. They must be documented by the manufacturer of the overall system.

NOTICE
The NGF system is subject to specific preventive measures in terms of electromagnetic compatibility. Install and operate it in accordance with the used standards listed in the technical data section of this document.

Intended use
The wireless tilting sensor monitors the position of the bottom hook block of a crane and helps to hold it in a horizontal position.
As a second application, it monitors the position of a load (e.g. with a parallel lift).

System components
The system consists of a transmitter (Tx) and a receiver (Rx). The transmitter measures the angles and transmits the measured values via radio. The measured values are determined by two independent measuring systems. The radio link is a 2.4 GHz low-energy system. The transmitter is powered by batteries or accumulators.
The two participants are paired in such a way that only one specific transmitter can communicate with the corresponding receiver.
The receiver (Rx) is attached to the roller head and receives the measured values via radio. The received data is then transmitted to the crane control via the LSB (Liebherr System Bus) interface.

Installation

WARNING
Loose screws can cause parts to come loose and fall off. Tighten all cover screws hand-tight.

The mechanical installation of the transmitter and receiver is the responsibility of the system operator.
The type of mounting and the mounting screws must be appropriate for the intended application.
The maximum diameter of the borehole is 6.5 mm.
During installation, ensure that no moisture penetrates the sensor.
Protection class IP65 is only achieved with a closed enclosure cover.

For correct wiring of the receiver, read the »Technical Data« chapter of this manual.

Battery

WARNING
A wrong battery type may cause too short runtimes, wrong voltage, or make the batteries not fit into the device. Use the NGF Tx with the specified battery type only.
Do not mix old and new batteries. Make sure that the battery charge lasts long enough for the intended work.

Use four 1.5 V alkaline batteries, type D, specified for industrial use (see technical data).

Battery insertion

Pairing

WARNING
If the receiver (Rx) is paired with a different transmitter (Tx) than the intended one, the measured hook tilt may be wrong. This may lead to a dangerously inclined hook block.
Make sure that the installed set of NGF Tx and Rx devices is paired correctly.

To have the transmitter and receiver communicate with each other, pair the devices once.

Before the pairing, make sure that the following conditions apply:

• Tx is powered up.
• Tx is in Idle Mode.
• The battery insulation strip has been removed.
• The enclosure cover has been removed.
• Rx is powered up.
• Rx is connected to the LSB bus interface.
• Rx and Tx are in the radio range.

To set the devices to Pairing Mode:

• Tx: press the pairing button on top of the inner case for >5 seconds.
• Rx: send the LSB pairing command. The command must include the transmitter serial number (to be found on the Tx label).

After both devices have been set to Pairing Mode, the receiver will send the new pairing ID to the transmitter. If this ID contains the correct TX serial number, the transmitter will acknowledge the pairing and both devices fall back to Idle Mode. The new pairing ID is saved on both devices.

Operation Modes

RF Rx NGF ULR2.4-safe

by the control system. RF transmission between both devices is normally <50ms (without radio disturbances). The mode is
changed by the LSB interface command.
Idle Mode| The crane hook is not driven. RF transmission interval is reduced to <500 ms to save battery power.
Mode is changed by the LSB interface command.
Disconnect/ Error Mode| The red status LED lights up.
(Try rebooting the system).
For possible causes, see the paragraph »Troubleshooting«.

RF Tx NGF ULR2.4-safe

by the control system. RF transmission between both devices is normally <50 ms (without radio disturbances).
If the radio connection is lost for >10 minutes, the transmitter changes to Sleep Mode.
Idle Mode| The crane hook is not driven. RF communication is reduced to <500 ms to save battery power.
If the radio connection is lost for >10 minutes,  the transmitter will change to Sleep Mode.
Disconnect/ Error Mode| The red status LED lights up.
(Try rebooting the system.)
For possible causes, see the paragraph »Troubleshooting«.
Sleep Mode| The transmitter wakes up every 15 seconds to wait for an active receiver. If an active receiver is found, the mode changes back to Active Mode or Idle Mode.
Deep Sleep Mode| Power consumption is reduced to a minimum. To activate this mode, press the pairing button
two times >5 s.

Design of a wireless range

The wireless signal is attenuated on the way from the transmitter to the receiver. In addition, the wireless signal is attenuated by obstacles. The degree of attenuation depends on the material of the obstacle. Ideally, with a direct line of sight, the wireless range will be greater than 300 m.

Penetration of radio waves:

The following influences may reduce the wireless range as well:

• High-frequency interference.
• LLAN or Bluetooth networks (or comparable 2.4 GHz networks) in the vicinity.
• Inappropriate antenna arrangement.

Radio operation
Transmission is carried out in the license-free 2.4 GHz ISM frequency band.

NOTICE
Simultaneous operation with WLAN or Bluetooth networks is possible. If there are repeated disturbances or radio disconnection, conduct radio network planning.

NOTICE
Portable and mobile HF communication equipment may negatively affect the functionality of the NGF radio system. This may lead to a loss of single telegrams or of the wireless connection. If needed, limit the number of mobile communication equipment in the vicinity of the NGF radio system.

To achieve optimum availability, install and operate the transmitter and receiver with a minimum distance of 1.5 m and a maximum distance of 300 m each other.

Coexistence and parallel operation of NGF24 systems
If there is more than one 2.4 GHz system in the same area that sends radio transmissions on the same frequency and at the same time, the telegrams will collide.

Troubleshooting

Possible causes for disconnected/missing wireless connection:

• The devices are out of wireless range.

• The battery charge of the transmitter is empty or no batteries have been inserted.

• The transmitter is in Deep Sleep Mode.
  (Press the pairing button to wake up the transmitter.)

• The receiver and/or transmitter are in an error state.
  (Try the power cycle of both devices.)

Maintenance and cleaning

With careful installation as described above, only minor maintenance is necessary. steute recommends routine maintenance as follows:

1. Check the enclosure and connection cable for damage and soiling. Clean enclosure on the outside only. Clean enclosure with household cleaning agents. Do not use compressed air to clean.
2. Check the plug-in connection.
3. After each start-up, perform a function test.
   If a battery is present, check the battery charge level.

Disposal

• Observe national, local, and legal regulations concerning disposal.
• Recycle each material separately.

Repair

NOTICE
Alterations to the device may cause irreparable loss of function. Do not alter the device.

Return damaged devices to steute.
