I can comment on the Transmag 2, but I have no idea how close the Transmag 2 is to the Intermag. The Transmag 2, an AC powered magmeter from years ago, was somewhat unusual in that it had two fuses, one called "device fuse" and the other "magnetic current fuse". The manual refers to electronic fuses used to protect the digital input and the digital output, but I have no idea which fuse might be related to which function. The attached two pages from the manual describe the location and the fuse numbers. The Transmag 2 had an active 4-20mA output, meaning it was powered by the line power that powered the meter. It was NOT loop powered by an external power supply. The only parameters in the configuration menu related to the analog output are 1. Menu item 1.7: the display of current in mA. 2. Menu item 2.5.2 Simulation of the analog output 3. Menu item 6.5.5 Current flow in % of the set full scale value, You might poke around to see if the analog output can be forced or simulated. If it can't, then the analog output is broken. The list of error message does not seem to include one that detects an analog output open circuit. My experience with process instrumentation is that if is not a fuse that is causing the failure of an active analog output, then the flow meter is no longer a flow meter, it is broken and not fixable, because there are no service instructions or parts available for magmeters. Siemens does not even post a manual for the InterMag. Attachmentfuses in the Transmag, manual A5E00102775-08_OI_en_Dec 2010.pdf (522 Downloads) |
