LTW 20Z 3.15 Operation Troubleshooting Automatic Shutdown 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).
Operation High Coolant Temperature Shutdown (e) LTW 20Z If the module detects that the engine coolant temperature has exceeded the setting of the high engine temperature switch after the Safety On timer has expired, a shutdown will occur. In such a case: 1. Allow engine to cool to a safe temperature and inspect coolant level in radiator. Add coolant as needed. 2. Carefully inspect coolant hoses and engine block for leaks. 3. Check that fan belt for water pump is tight. 4.
LTW 20Z 3.17 Operation Receptacle Panel Overview The Light Tower is equipped with receptacles for running accessories and tools from the generator.

LTW 20Z 3.18 Operation Load Balancing Overview 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.
Operation 3.19 LTW 20Z Emergency Stop Switch Location The emergency stop switch (f) is the red button located on the receptacle panel at the rear of the Light Tower cabinet. Operation Activate the emergency stop switch by pushing the red button in. Pushing the emergency stop switch opens the main circuit breaker and the fuel solenoid and results in the engine shutting down and an indicator to illuminate. The switch will remain in until the button is pulled out.
