2800 Safety Shutdown Device
AMOT Model 2800 fuel rack actuator is a safety shutdown device which senses oil pressure or other control pressure. This device is typically connected to an engine fuel rack governor or fuel pump stop lever and should a loss or drop in oil pressure occur below the set point, it will trip immediately.
Features and Benefits
- Entirely mechanical - no external power required
- Snap acting - immediate shutdown upon sensing loss of oil pressure below setpoint
- Easy installation and operation - reset latch emergency stop and multi-positional reset lever
Specifications
| Housing: | Hight strength aluminum die casting | |
| Internals and leavers: | Precision sintered steel castings | |
| Finish: | Black anodized | |
| Pressure connection: | 1/4" NPT or BSPL | |
| Max. pressure at inlet: | 11.7 bar | 170 psi |
| Trip pressure adjustment range: | 0.35 to 2.8 bar | 9 to 11 psi |
Applications
- Monitors pressure or temperature on rotating machinery in hazardous and industrial applications.
Operation
Model 2800 is a snap acting device monitoring low lubricating oil pressure or other control pressure. An emergency stop handle and a trip pressure adjusting screw are standard. Factory set to trip at 10 psi (0.7 bar) and field adjustable, from 5-40 psi (0.35 - 2.8 bar).
A trip Lever is installed on a splined shaft, and can be clamped in any of 36 radical positions to facilitate installation in most applications. The lever permits mechanical linkage between the tripping unit and the engine governor control, fuel pump stop lever or other mechanism. Predrilled holes give a wide range of connection options.
A standard Reset Latch is supplied. The Reset Latch locks the trip lever in the “run” position until oil pressure is up to normal operating pressure, then the latch releases thus arming the device.
