LED Colour Assignments
With the classic variants (24 V DC, 120 V AC, AS-i, DeviceNet), the setting can be changed by a service
technician, if necessary.
The parameter values and the assigned display priority are listed in
“Table 18” .

Table 18: Display priorities when position feedback overlaps - can be selected using parameter “PRIO”
*) Factory settings: “PRIO 24”
When the position feedback is from S4 (external initiator), note whether the external initiator acts as an “Opener”
(NC contact) or as a “Closer” (NO contact) – see “Table 8: Position feedback of the external initiator (S4/S4IN)
depends on the mode of operating” on page 138
If the factory setting of S4IN (normally open contact = NO) is to be changed, this can be done for IO-Link
and büS/CANopen variants via software using the sensor parameter “Circuit Function External Initia tor
