Start-Up And Configuration; Initializing The Actuator - Samson 5827 Mounting And Operating Instructions

7 Start-up and configuration

7.1 Initializing the actuator

To achieve correct position feedback, the
actuator must be initialized. This is also
necessary after changing the configuration
at the actuator.
The actuator can be initialized at the
actuator itself or over the TROVIS-VIEW
software.
WARNING
!
Risk of injury due to the actuator stem
extending or retracting (with form-fit
attachment).
Directly after connecting the supply voltage,
the actuator stem can start to move.
Î Do not touch or block the actuator stem.
NOTICE
!
The process is disturbed by the movement
of the actuator stem.
Î Do not perform the initialization while
the process is running. First isolate the
plant by closing the shut-off valves.

Start initialization
1. Place the function switch into the re-
quired position.
2. Switch the function switch briefly from its
position to the other position and back
again (see Fig. 7-2).
The red LED indicates that initialization is in
progress (see Fig. 7-1).
Note
The actuator automatically performs a zero
calibration as soon as the supply voltage is
applied to the L and N terminals. This is
indicated by the red LED blinking (see the
'Operation' section). This function does not
replace the initialization procedure.
NOTICE
!
Risk of malfunction due to incomplete or
incorrect start-up.
Î Start initialization
Î Complete the entire initialization
procedure until the red LED is no longer
illuminated.
The actuator is not ready to use until the ini-
tialization is completed.
