SW-200B

The Dynalco SW-200B provides reliable engine overspeed protection. It has three adjustable relay setpoints: number one is overspeed. Uses for the two auxiliaries include crank disconnect, generator field-flashing, and speed monitoring. Setpoints are field-programmable and can be tested without overspeeding. Housing is gasketed and sealed.

PNT-202

Used In Connection With The SPV-200 Solenoid Pneumatic Valve When the present setpoint overspeed is reached, the Dynalco PNT-202 trips the SPV-200 Solenoid Pneumatic Valve. The valve opens, latches, bleeds to the atmosphere and shuts down the engine if it is connected to the engine pneumatic control system. The PNT-202 also effects shutdown when one of the pickup signals disappears or when an attempt is made to start up with only one operational pickup. The second setpoint can trip the same valve or a separate valve. It can be field programmed as an underspeed setpoint, or as a second overspeed setpoint, or crank disconnect. When set for underspeed, no inhibit is necessary on startup as this setpoint becomes enabled only when the speed exceeds the setpoint.
