1.2.1.2 Mechanical Trip and Lockout Mechanism
A mechanical trip hook is located at the bottom of the tank (Figure 3). When the hook is pulled down, the
OSM
is mechanically tripped, locked in the OPEN position and electrically isolated from the driver. An “OSM
Coil
Isolated” warning event is generated by the RC5_4 to provide indication of the locked state. The OSM
remains locked and cannot be operated until the trip hook is pushed back into the operating position.

1.2.1.3 Mechanical Position Indicator
The position indicator is located under a protective cover at the bottom of the tank and is clearly visible from
the ground (Figure 4). The indicator color is red when the OSM is closed and green when it is open.
