Variant 2: variac NX 1-260-xx Rack connected (MFT 100)
Enable option
“Rack connected”
In this case the relay in the MFT 100 is switched on/off via the PF1 (compact NX) switch. The connection from
the variax NX (PF2) to the compact NX (PF2) remains and does not need to be changed. The PF2 switch in the
compact NX remains open and is not used for this test. Instead, there is another connection from the variax NX
(PF2/N) to the front panel in the rack. From there the controlled variable is fed to the MFT 100.
