I have a Garaventa Elvoron that is giving me some grief. I have the Electrical Schematic for the Elvoron MRL power board connections. I have been studying it to see if I can get a better idea of what is happening here, but I have an unidentified component that I am hoping someone can tell me what it is.
At the top of the page, to the right of T1, there is an unidentified rectangular symbol connected across L1 and L2. From the top of this symbol there is a line labeled "48VDC" that connects to pin 8 of PF relay. Pin 1 of PF connects to Pin 8 of PF1 relay and Pin 1 of PF1 connects to Line 2. Is this symbol for a 48 VDC power supply that connects the two relays in series with presumably 24 volt coils? If the connection to PF is positive, would the negative conductor be connected to L2 internally? I find this a bit odd.
