Figure 2.2.4: Control Connections - MICROMASTER Vector
Note:
Do not use the internal RS485 connections (terminals 24 and 25) if you intend using the external RS485 connection on the
front panel e.g. to connect a Clear Text Display (OPM2).
DIP switches select between voltage (V) and current (I
)
analogue inputs and also select either a voltage or current feedback signal
(see Figure 4.1.2: DIP Selector Switches).
These switches can only be accessed when the flap in the the front cover is raised
(see
Figure 2.2.1).
Insert small blade screwdriver (max. 3.5 mm)
as shown, while inserting control wire from
below. Withdraw the screwdriver to secure
the wire.
