4054 Pneumatic Trip Indicator
AMOT Model 4054 Trip Indicators are designed to show which sensing device in a safety control system has tripped and caused the engine to shut down. The 4054 Trip Indicator is anodized (Gulfproofed) to resist corrosion in seacoast atmospheres. A transparent plastic cover is provided to protect the shaft. It is suitable for air, gas or oil safety control systems. Any desired number of sensing valves and Trip Indicators may be used in the safety systems.

Sensor Trip Indication in Pneumatic or Hydro-Mechancial System
The 4054 is typically piped to the VENT port of an AMOT sensing Valve. When the sensing valve vents, the pressure forces the red shaft of the 4054 out where it can be seen. A small detent latches the shaft when fully extended, preventing resent due to vibration. The shaft is manually reset by pushing on the flexible plastic cover until the shaft is flush with the indicator face. Because lube oil is the control medium in the typical system shown in Figure 2, there will not be direct indication when shutdown is due to low oil pressure. If there is a system shutdown and no indication it should be assumed that low oil pressure is the cause.
