Best thing would be to check 4-20 mA signals sent to EGATROL like Pulsation High /Low /Middlea and data acquisition signal status if ok

Oh ok i see that it is EGATROL ( ABB advant platform for the Control system)

Have a careful read on this very interesting article it clearly describe the Pulsations protection philosohy * https://patents.google.com/patent/US7751943 Sound like you can at least try to simulate puslations by Frequency generator like..on the closed loop signal to the vibrometer Do you have...

A dynamic pressure sensor is fitted to each combustor on most modern gas turbines to measure pressure pulsations and combustion dynamics. This is because the turbines burn fuel as lean as possible to reduce emissions to environmentally acceptable levels, but in so doing create metastable flame...

HI Thank you for the feedback! When i referred to calibration of the sensor it was because I was only asking if that sensor used to be calibrated at site.. I will do some investigation on how to solve this issue.. What is OEM of the Vibro meter ? Is that old Meggit device I use to work on...

See here how to read pulse number receive at the interface of the encoder:

Hi Yes I got the details Did you check that OEM manual page is for DINT registers Read

Thanks a lot for the feedback By the way did you troubleshoot that issue..

9-PIN D-SUB encoder interface ?

What is encoder interface installed ?

Hi Can you rovide reference number of the AUMA Model actuator Seems that as per OEM manual that configuration need to be reviewed Is there a way to reload actuator data from AUMA CDT 2020 Also what kind of remote command/signal is a DCS /SCADA?

Looks like D6513 IS ALSO Designated as H9971 Do you have a modbus list/mapping ? Do you know how to create program with DMC external master There is a description on the manual oK i GOT it the manual is saying that the Source signal of this DMC extarnal master block is the pulse that...

Hi Manual of the OEM Mentionning DMC external master as a program for encoder reading or through modbus .... See following screenshot:

Thanks for the update /feedback hope it can highlight some points you lookin for I will have a search on that DLN1+ ON Frame 6B I use to work a lot on these frame type with GE Europe Belfort

Who is the Vendor/OEM of this device also designated as MBX20 AA04 as shown on the P&ID that i got ..for this IGV Trip relay Frame type of the unit Packager of this unit

Have a good and careful read on this article ( all is well explained on Pulsation measuring/protection: https://patents.google.com/patent/US20120279229

Pulsation measurement equipment is an integral part of a gas turbine protection system. The purpose of the equipment is to supervise combustion phenomena like pulsation (screeching, rumbling, humming, etc.) to cause an immediate engine shut down or to initiate a change in the engine operation...
