Logic voltage The logic voltage is supplied either together with the load
voltage via the power supply connection (internal) or separ-
ately from the load voltage (external) via the field bus
adapter FBA-... . The MTR-DCI-32 can only be supplied with
logic voltage via the field bus adapter.

Logic voltage supply via field bus adapter FBA-...
The load voltage is supplied via the power supply connection.
The logic voltage is supplied via the field bus adapter FBA-... .
Due to the separate power supply, the load voltage can be
switched off e.g. in the event of EMERGENCY STOP. Despite
this, the controller still functions and maintains its reference
position.
Information on the connection specifications of the field bus
adapter can be found in chapter 3.6. and in the assembly
instructions for the field busa adapter.
Switch-on sequence Do not switch on the logic voltage after the load voltage,
as the MTR-DCI may thereby be switched off and on again
(Reset).
Failure of logic voltage If there is a failure of the logic voltage, the controller will
switch itself off.
With MTR-DCI 42, 52, 62: If the load voltage is still applied,
the controller will switch itself on again, but is no longer
referenced.
