Did you read the manual about this 703 alarm? Maybe there is in the manual what to do when this alarm occurs. You can also contact the company that supplied you the gas turbine, maybe they can help onsite.

These are the extra rugged types of Sick and 300 euro's is quite a normal price for them. It is indeed AC powered and most often they switch with a switchover relay contact, but it can also be there it is acting as a NPN/PNP proximity sensor. But my take with most Sicks is that they most often...

Maybe it is 32 bit (2 16 bit words combined). Read 1 word higher and 1 lower and see what is in those registers (if it makes sense at all) It can also be signed iso unsigned. Is it not in the manual, see the modbus addresses list of the device

I fully understand, that is why I always implement HACCP datalogging as standard in my equipment and give it to customers as an surprise. They ask: can you also do HACCP? I say yes: just stick the usb stick in and it logs the temperature with an adjustable interval into a CSV file. It is very...

John is right on points 1, 2 and 3. Extra about point 3: some slaves take time to switch from receiving to transmitting and visa versa. There is often a setting in your driver for that. In the pro-face driver that I use for modbus it is the wait to send setting. So the master activates the bus...

Welcome to the Modbus community. Is it one of the most simple and reliable fieldbus interfaces that I know of. I'm working with it successfully now for about 15 years implementing all kinds of catering equipment (deep fat frying furnaces, grillplates) and also for wireless haccp datalogging...

contact this company in the Netherlands, they have a lot of experience with this: https://ex-machinery.com/

Recently I wrote a web page on PID controllers, their history, what the P, I and D factors actually do and rules of thumb on how to set them. All pages are in English, Dutch and German language. See PID: https://cascade.net/en/pid-temperature-control-algorithm/ The same for the history of...

contact supplier and buy a new one, the memory is damaged.

please contact the supplier of the sensor, I'm sure they can send a manual or send and engineer for service.

That was also my first idea. But for some kind of reason many people here on the forum are afraid of contacting the (original) supplier of the equipment.

so does that mean this box contains the current transformers for measuring the motor current?

is the CT box the connection terminals for the motors? Normally "CT" means current transformers. What can be, is that you have a 2 speed motor (Dahlander windings). In that case you wire it in the high speed connection and just drive it with the VFD with a ramp up so the low speed windings are...

depends.....does the CT box (I'm guessing that it measures current, since you supply only very sparse information) measure true RMS?

did you read the manual, or contact the supplier for assistance?

Than it is a very bad supplier, next time take one that gives longer support. I suggest a Japanese company.

Please contact your supplier of the equipment, I'm sure he has all the info you need.

please contact the company where you bought the equipment/software from.

please download the manual and contact the supplier

Good that you inform us that you pinpointed the reason why it didn't work. We can help you with a replacement controller that has a RS485 Modbus interface (ProfiBUS/ProfiNET/EtherCAT/Modbus TCP/EtherNetIP/DeviceNET/CC-Link/Mechatrolink/MAPMAN also possible). See our RB100...
