Manual Mode; Operation Using Memory Pen - Samson TROVIS 5757-7 Mounting And Operating Instructions

8.3 Manual mode

Manual adjuster
Fig. 8-1: Manual adjuster and travel indicator
Manually changing the stem position
The manual adjuster can be used to move
the actuator stem to the required position. A
manual adjustment of the stem position only
makes sense when the power supply is
switched off as the stem position is deter-
mined by the actuator in closed-loop opera-
tion, meaning any manual adjustment would
be automatically corrected by the actuator.
The stem position is changed at the manual
adjuster (see Fig. 8-1):
Î Switch off the supply voltage.
Î Turn clockwise
The actuator stem extends (approx. four
turns for 1 mm travel).

Travel indicator
Î Turn counterclockwise
The actuator stem retracts (approx. four turns
for 1 mm travel).
Travel and direction of action can be read
off the travel indicator on the side of the ac-
tuator housing (see Fig. 8-1).
8.4 Operation using memory
pen
Î See u EB 6661.
The memory pen can be loaded with data
configured in TROVIS-VIEW and the config-
uration data transferred to one or several
devices of the same type and version.
Additionally, the data from the device can
be written to the memory pen. This allows
the configuration data to be simply copied
from one device and loaded onto other de-
vices of the same type and version.
Note
On inserting a memory pen that is empty or
that contains data from another type of de-
vice or another version of the same device
into the serial interface port of the actuator,
the data from the actuator are uploaded to
the memory pen regardless of the status of
the memory pen and any other data on the
memory pen will be overwritten.
