SAFETY INSTRUCTIONS

Identity code

The remote control and the machine are connected by means of a pre-programmed ID code. The ID code ensures that the right remote control is used for the right machine.

If several machines are used at the same workplace there is a risk of mixing up the remote controls.

Switch on the current to the remote control and the machine. Press the horn to see which machine is con- nected to the remote control. The machine will beep and ßash three times. Do not activate the remote con- trol before you have ensured that the correct machine is being operated.

When steering the machine using cables, the ID code is suppressed and the same remote control can be used for different machines if these have the same control system version.

Automatic frequency hopping

In the event of interference in the communication, the frequency changes automatically to guarantee interfer- ence-free transmission.

Emergency stop/machine stop

When the machine stop on the remote control is pressed, the power to the circuits controlling the communication with the machine is interrupted. The machine engine stops due to the interruption of the transfer of signals to the machine’s electronic device.

The emergency stop on the machine switches off the main power to the machine.

Protective earth

The machine and its components are connected to grounding conductors in the power cable. If there is a fault, a fuse is tripped and the current is disconnected.

The machine must be connected to a power point with a protective earth. If there are no grounding conduc- tors, or if they are connected incorrectly, have come off or are loose in a terminal, the current will remain connected and touching the machine can be highly dangerous.

If there is reason to believe that the protective earth has been damaged, the machine must be turned off and the power cable removed until such time as the protective earth has been restored.

Always connect the machine through an earth-fault breaker with personal protection, i.e. an earth fault circuit breaker that trips at an earth fault of 30 mA.

Hydraulic brake

Hydraulic motors are used when moving the machine. All hydraulic motors are Þtted with brakes. These hydraulic motors contain counter balance valves that prevent uncontrolled ßow through the motor, e.g. when manoeuvring down a slope or when the machine is parked. The counter balance valve closes the tank opening when the drive motors are not being operated.

Mechanical brake

The machine’s drive motors are equipped with a me- chanical parking brake. The machine is braked until its drive function is activated.

Automatic phase rotation relay

The automatic phase rotation relay prevents the elec- tric motor starting with the wrong rotation direction thus causing mechanical damage.

Motor protection

To prevent overloading, the motor is equipped with bimetallic relays in the motor linings that disconnect the power if the motor gets too hot.

If the motor is too hot it is not possible to operate the tools. The rest of the machine’s functions can be run at half speed in order to facilitate evacuation of the machine from risky environments.

Once the motor’s temperature has fallen to a normal working temperature all functions can be used again.

The machine’s softstarter is Þtted with a motor cut-out that trips if the current is too high for too long a period. The machine’s functions return to normal position after three minutes.

Fuses

Fuses are used to protect the following components as well as to prevent Þre in conjunction with faults or if electrical components are overloaded.

Pressure relief valves

The machine’s hydraulic system is equipped with pressure relief valves. They protect the hydraulic system against too high pressure and the mechanical components against overloading.

Pump-around valve

The pump-around valve drains the hydraulic ßow into a tank and relieves the pressure on the hydraulic sys- tem. No pressure enters the cylinders and it prevents the risk of unforeseen movements. This happens, for example, after three seconds of inactivity.
