Operation

Background

There are five automatic shutdown conditions:

„ low oil pressure

„

„ high coolant temperature engine overspeed

„

„ engine underspeed engine overcrank

When these occur, the operator can perform certain diagnostic tests to help identify the problem. Most of these diagnostics deal with the engine.

When a fault occurs, the fault must be removed and the shutdown alarm must be cleared to reset the Engine Control Module (ECM).

The generator, however, can also cause problems. Consult a qualified electrician or your nearest Wacker Neuson dealer for possible causes of generator problems.

WARNING

Possibility of personal injury or equipment damage. A machine down for service must be secured so that no one is allowed to run it until repairs are made.

Load Balancing

Overview

Operation

To help in balancing loads, each outlet on the LTW20Z3 is marked with the phase(s) to which it is connected.

When connecting single phase loads to the LTW20Z3, it is important to balance the loads, especially if the machine is also powering three phase loads. Unbalanced single phase loads cause unequal three phase line voltages.

Unequal line voltages applied to a three-phase induction motor produce unbalanced currents. This condition increases the motor temperature compared to a motor operating with balanced line voltages.

NOTICE:

If line voltages are unbalanced, the motor horsepower rating will be derated in accordance with NEMA MG 1 Part 14.

General Options

About Brakes

Your machine may be equipped with electric brakes or surge brakes. See

Towing

Safety

for more information about connecting and checking the brakes.

Electric

Brakes

Machines equipped with electric brakes draw power from the tow vehicle. An electrical wiring harness connects the tow vehicle’s brake pedal to the brake actuators on the trailer. Pressing the brake pedal applies the brakes to both the tow vehicle and the trailer.

Surge Brakes

Machines equipped with hydraulic surge brakes do not require any electrical connection to the tow vehicle. The braking system is completely self-contained, using momentum to actuate the trailer’s brake master cylinder and apply the brakes when the tow vehicle slows or stops.

Internal Light

Storage

This option allows the light fixtures to be detached from the tower and stored inside the Light Tower cabinet. Internal storage protects the fixtures from damage on the job site, during transport, or during long-term storage.
