Dear Members,
We are a Boiler manufacturer. We have supplied 2 Nos Low Tension motor - 415V; 50Hz 0f 110 Kw for fan application. Each fan is having full load capacity. The first fan is with VFD and the second is with star/delta starting and inlet regulating vane flow control. The boiler...
We are having a ABB make VFD - ACS800 for fan application. It was commissioned and working for last three months. Now it is not responding to DCS input (4-20ma) and increse/decrese 24 V DC input from VFD panel for any increse/decrease command. Any change made from these two destinations leads to...
Torque/Thrust calculation for Dampers/gates.
We want to calculate the Torque/Thrust required for opening/closing of the Damper/Gate.
The data available with us
1. area of the damper/gate in Sq.mm
2. Opeating pressure in mm water col. (g)
3. operating temperature in Deg. C
The damper is...
I would request the Forum Members to suggest the type of cables to be used for connecting following I/Os to DCS/PLC based on their experience.

Flame Intensity indicates the qulity of flame inside the chamber. This is normally measured by the Flame Scanners. There are three types Scanners available in the market viz. Ultravoilet(UV), Infrared(IR) & Visible Light. The selection of the type of Flame Scanner for the application depends on...
A German Standard called KKS Numbering system is available. I do not have the web Address.
However we use to have a method of indiacating the location of the instrument. Examble
for transmitter we can have PT xxx. The 1st & 2nd digit to indicate the location and 3rd digit to indicate the Sl...
Dear Mr. LHA,
Thank you for your reply. However the refferred home page " https://tsc.wes.army.mil/" is blocked and able to open. If you are having a copy, kindly post the same.

I require Standard (NEMA etc.)symbols (which can be used by copy and paste method) for prepation of elecrical circuits/Wiring diagrams, control schemes and logic diagrams.
Can any of you help me.
Thanks in anticipation
R.Thiyagarajan.
Do not fully close the damper. Keep it at minimum opening position if there is no back presure.
or
If there is a back pressure, start opening the damper immediaely after giving the start command.
