SLLD

II don't know but I bet the equipment manufacturer does. No joy over the phone, then?

Sorry, Old Bean. I don't understand your abbreviations: SLLD, TRIP, ETD? Etc. I always have trouble with TLAs and FLAs.

Open the TBD port and check to be sure that the LIO is set to the high setting.

If not re-set it.

Then, reset the upper and lower limit sensors in the TCP panel.

Disconnect the primary filter before changing the TRIP oil setting back to manual.

Refer to page 13 of the operator's manual for the initial settings and work incrementally up from there.

Check page 36 for the start-up procedure and follow it.

If that doesn't work, call the factory. Their number is on the back page of the manual and inside the door of the IBTT panel.

You didn't mention the NFG unit. How despicable!

Those are only on the SLLD-A3 rev b models, not on models with a TRIP oil.

See page 96 of the trouble shooting guide for details.

"The primary trip function is independent and diverse from the emergency trip function as explained below (refer to Figure 10.2-5, Turbine Overspeed Trip System Functional Diagram). Two-out-of-three logic is employed in both the primary and emergency overspeed trip circuitry. Each trip function can de-energize its associated trip pilot valve solenoids of the electrohydraulic Emergency Trip Device (ETD). The ETD is composed of two independent trip valves, each with two normally energized fail-safe solenoids. For each trip valve, each trip pilot valve solenoid is powered from a separate power source. The solenoids de-energize in response to detection of an overspeed condition by the turbine speed control logic. De-energization of both trip pilot valve solenoids is necessary to cause the spool in their respective trip valve to reposition, which depressurizes the emergency trip fluid system, rapidly closing all steam inlet valves and indirectly closing the steam extraction nonreturn valves. Accordingly, the repositioning of only one of the two trip valves is necessary to trip the main turbine. A single electrical component failure does not compromise trip protection, and does not result in a turbine trip. Each trip valve in the ETD is testable while the turbine is in operation."

You are just too kind sometimes.

...and the answer remains the same, get someone qualified on site to do your job for you! Twiddling around with something as sophisticated and important as the ETD (Emergency Trip Device) for your governor/turbine is NOT a job for amateurs. Property damage will ensue and lives may be lost.
