CHARGER INTERLOCK
 |
|
An often overlooked spot on the Skyjack electric powered scissor lifts is the A.C. interlock connection. It is located at the rear of the battery charger and is labeled as AC Interlock. If the label is missing, look for two 14 GA. wires (one black/one white) leading to a white connector. See figure 1:

| It is important to always check that all the warning and indicator lights are working at each inspection or service. These lights tell the operator the condition of the engine, safety status, power on, and other critical information. They can also help a technician troubleshoot a problem. Taking the time to check and replace any non-working bulbs or LED lights is something that is as important as tightening wheel bolts or checking safety switches. |

The purpose of the interlock circuit is to prevent the unit from being operated while the charger is plugged in. When the charger is connected to an AC power source, the 120V relay (L1CR) inside the charger opens the contacts cutting power from the main circuit breaker on wire 3A to the 05 wire (power to the emergency stop switch) preventing the machine from operating.
