Okay will have a look on a Frame 5 P&ID ..and come back with comments Also what have been done before this issue happened.. Can you give a brief description of the issue at site..

Hello Can you provide frame type ..also a P&ID would be welcome ...

Hello, Okay @bertus ... Stay blessed

Hi Dave, Welcome here ! I am James and I am working on power generation & industrial systems mostly...since 17 years now.. Nice to meet you here...Lets share and learn about problem solving ... Stay tuned and blessed... James

CSA, As Original poster did not update us on the issue..we can consider that the thread is "closed " ... No I am not a moderator but some people come here and post , but they leave without replying...I do not like that .. I know that you understand it ..

What type /model brand serie of this unit ... Dont you have any OEM operation& maintenance manual... Is there kind of lube oil tank breather system flame trap ( primary and secondary usually two are installed..) The operations /coordiantions in case of a failure /loss of the ejector or...

Any update ... Thx for replying..

A quick feedback would be welcome ! We are not posting/doing efforts here for nothing...

Okay ! All the best in site activities...

Yes definitly !

You got also to investigate on that ALarm ID 123 ..according to manual you need to verify the configuration of LedDiag parameter of the involved pack ... For the Alarm ID 56 Dual speed sensors reported speed that differ than more than the configured dual_diff_limit... Now it is up to you to...

Hi The NTP (Network time protocol) may not be setted /configured properly... I advise you to search on that side.. For a global time synchronization. Any time! Controls Guy25

Good day gents, Can you tell us what type /model of the Gas turbine is it ... As I Found on GE manual ( the right one that the alarm ID 53 /54 of WREA is defined as : The speed repeater output does not match the speed input signal Followings need to be checked ( possiblse causes) : One of...

VFDs do not allow plugging due to the stress on the switching devices. Most VFDs are probably sufficiently protected from damage is plugging occurs, but it is generally considered to be an abuse of the product. As described by @Transistor, regenerative braking tends to occur whenever the...

There are 4 different methods of braking a motor that VFDs can use. Two of them, Dynamic Braking (DB) and DC Injection Braking (DCIB), are included in most standard VFDs. Charles Cowie already described the Dynamic Braking wherein the kinetic energy in the rotating load is transmuted into...

It depends. Older cabled lifts/elevators used DC motors, massive things up to 200HP. Smooth as silk due to the inertia. Now lifts use AC induction motors or AC permanent magnet servo motors with static inverters. Motors may be geared to the ropes so the motor may be a cheap high RPM-low torque...

The latest elevator designs use 3-phase induction motors with variable frequency drive electronic controls. Some may also use a similar system with permanent magnet (brushless) DC motors. Some current and prior designs may use commutator-type DC motors with electronic controls. Through...

First of all you have to know what types of operation is done by a lift? The answer will be traction operation… In older days for traction purpose DC series motor was the best because of its very high starting torque . But there are several disadvantages of DC SERIES MOTOR Poor speed...

Hi Any update That would be appreciated to hear from you about this issue after our advises...
