Current / Voltage mode
This switch setting is for internal use and debugging only by authorized Danfysik service
personnel. In general it sets the unit to a voltage supply where a 20A (full scale) setting gives a
voltage output of approximately 35V.

Hint:
The time constant of the magnet (transfer function of the load) can be measured, using
the SYSTEM 7000 in the voltage mode together with an attached gain/phase analyser.
Machine Protection System signal
The Machine Protection System signal (Abbreviated to “M.P.S. signal”) is available through an
Amphenol connector located on the back of the cabinet. This signal is produced by AND’ing;
the three signals; ON status, Sum Interlock and the Main contactor is on.
The M.P.S. signal is high when the SYSTEM 7000 is ON.
Sum interlock and the ON status can be excluded from the “M.P.S. signal”
