Hello,
I'm looking to figure out what exactly the purpose of these switches is found on the amplifier board of my Endress+Hauser Promag 50. I cannot seem to find any reference to them in either one of the manuals for the device I am referencing so I am not sure if I am just missing it or if they are just not mentioned. My best guesses here are 1) read/write permissions for the HART variable assignment, but I'm a little put off by the "ON" on the right, so it would be a little odd for only the fourth variable to be switched to the ON position; or 2) something maybe specific to signal processing... dampening... etc. I would be interested in maybe flipping them to see what happens but with only the transmitter head and no sensor I am not sure I would see a massive difference unless maybe under simulated conditions. Considering that they can be switched, I need to ensure that they haven't been switched; I would also assume that if they can be switched, someone will switch them. But with seemingly no mention of it in either manual I can't verify the factory positions for them.
These are the manuals referenced:

These are the switches and the amplifier board of the Promag 50 on which they are found:

 

Thanks for the links to the manuals.

The Operating Instructions manual states that the HART write protection can be switched on and off using the HART WRITE PROTECT device function (→ "Description of Device Functions" manual), (Bottom of page 64).

But the word "write" does not appear in the Description of Device Functions manual and the word "Protect" is used with reference to the Access codes used for security, which are configured via keypad/display.

No reference to DIP switches or mechanical switches of any kind. Sorry I can't help.
