SED2 Operator Panels

NOTE: The BOP or AOP can connect to or disconnect from the SED2 without switching off power.

Basic Operator Panel (BOP)

The Basic Operator Panel (BOP) provides access to the parameters of the SED2 and allows for

application-specific settings of the SED2.

The parameters and measured values are shown in a 5-digit LCD display. The BOP can mount directly

onto the SED2 or, alternatively, it can mount into a control cabinet door using a special installation kit

(SED2-DOOR-KIT1 or SED2-DOOR-KIT2).

You cannot store parameter data with the BOP.
