Control and operation

Setting the machine into operation

Check the controls function

Move the safety lever to the down position. Check the controls function: carefully operate the joysticks and pedals. Check the slewing gear brake is functioning correctly.

Preheating of the hydraulic system

If the hydraulic oil temperature is below 8°C: current warm up phase is displayed. As soon the hydraulic oil temperature rises above 8°C, the full power of the machine is available.

Note

The warm up phase for the hydraulic circuit can be activated and deactivated at the display.

Starting procedure failure

If the motor does not start: Wait for at least 10 minute before the next attempt to start the motor. If the motor is cold: try maximun 3 starts. If the motor is warm: try maximun 2 starts. If there are two unsuccessful attempts to start the motor, establish the cause of the fault and eliminate it.

Activating the emergency off-switch

Danger!

Falling load!

Damages, injuries, death.

Make sure that no one is under the lifted load.

Push the emergency off-switch S2-1. The main supply circuit is switched off.

Restarting the machine after an emergency shutdown

After an emergency shutdown:

S2-1 must be unlocked; t (in case of 3 buttons are mounted).

Push lightly on the emergency off-switch S2-1 and turn it clockwise. The emergency off-switch S2-1 is unlocked.

Push and hold the key S208 for 5 seconds. The main supply circuit is reset.

Switch on the main supply circuit. See chapter 3: "Switching on the main supply circuit".

Start the electric motor. See chapter 3: "Starting the electric motor".

3.3.6Starting aids

Hydraulic oil preheating (optional extra)

The hydraulic oil is preheated before starting using hydraulic oil preheating. It is working when the client power supply is switched on. The hydraulic oil preheating switches off when the temperature is reached.

3.3.7Immobilizer with electronic ignition key (option)

System description

The system consists of a mechanical locking system and an independently functioning, electronically coded, immobilizer. When activated, the electronically coded immobilizer disconnects the starting and main control circuits of the machine.

The control of the immobilizer is microcomputer based. The electronic key of the immobilizer is a transponder, which is securely integrated into the key handle. Activation of the immobilizer

Turn the key in "0" position. the immobilizer will be automatically activated after 5 seconds. Pull the key away from the ignition switch.

Note!

The immobilizer is activated and will stay activated, as long as the key stays in position '0', no matter if the key remains inserted or is pulled out of the switch.

Deactivation of the immobilizer

Insert the key into the ignition switch and turn it to the contact position "1". the immobilizer is deactivated.

Note!

Reading of the transponder will only take place when the mechanical key in the starting switch has made alive the control circuit of the machine (24V on clamp 15 ). This makes it necessary to first open the mechanical locking system before the electronic key is checked. Thus, the immobilizer cannot be manipulated as long as the ignition is turned off.

The master key 5 is marked by a red key knob. The master key must be carefully stored as there is only one master key available for each immobilizer.

This master key is only to be used for imprinting new operation keys 6 (blue keys).

The master key can not be used for deactivating the immobilizer. This prevents the usage of the master key for operating the machine.

At delivery there are only two operation keys joined to the immobilizer. Other operating keys can be ordered separately.

Imprinting procedure of an operation key

To imprint an operation key, proceed as follows.

Insert the master key into the ignition switch and turn it to the contact position "1" . After a maximum of 5 seconds turn the master key back to "0" position and take it off the ignition switch. the electronic system of the immobilizer now expects the operational key to be imprinted within the next 15 seconds.

During this lapse of time, insert the operation key to be imprinted into the ignition switch and turn it to the contact position "1" . the key is registered as a new valid key.

Control

Note!

If no key to be imprinted is recognized within 15 seconds, the imprinting procedure automatically terminates itself. To imprint several operation keys, the keys may be inserted into the ignition switch in succession. The individual keys must stay in position "1" for at least 1 second.

Up to 10 operation keys may be imprinted per master key.

It is by the fact possible to enable one operation key to several immobilizers, e.g. to create a general operation key valid for several machines or for a machine pool.

Deleting imprinted operating keys

Deleting imprinted operating keys may be necessary after the loss of an imprinted key.

During the deletion procedure, all imprinted keys will be deleted. After all keys have been deleted, they must be re-imprinted to recover validity.

Insert the master key into the ignition switch, turn it to the contact position "1"and keep it for at least 20 seconds in this position. all imprinted operation keys for this master key are deleted. all existing operation keys may be reimprinted .

Note!

The code of the master key will not be deleted during the deletion procedure

Operation security

Should more than 5 invalid keys be used in the ignition switch within 1 minute, so the immobilizer will be activated for 15 minutes and will not accept any valid keys during this period. This procedure will prevent the 'trying out' of multiple keys and accidentally finding the correct key.

If several invalid keys are recognized without the ignition switch having been brought into the position '0', the immobilizer stays activated for 15 minutes and will not accept any valid keys during this period. Only after those 15 minutes have expired, and after the ignition switch has recognized the position '0', will valid keys be accepted again. This will prevent keys from being tested without using the mechanical ignition switch, e.g. when the ignition switch is forcefully brought into position '1'..

Function security

An interruption of the supply line or other control lines will not deactivate the immobilizer or delete data (e.g. data codes).. All relevant data are stored in a nonvolatile memory. Magnetic fields will not deactivate the immobilizer.
