Operation
Î Turn counterclockwise to retract the actu-
ator stem (approx. 4 turns for 1 mm trav-
el).
Changing the set point W1
The default settings of set point W1 is 60 °C
and W2 is 70 °C.
These set point can be changed in the TRO-
VIS-VIEW software.
To manually adjust the W1 set point without
TROVIS-VIEW, turn the set point potentiome-
ter (11 in Fig. 1) located on the printed cir-
cuit board of the actuator. The adjustable
setting range is between 10 and 100 % of
the measuring range (default: lower measur-
ing range value Xmin = 0 °C and upper
measuring range value Xmax = 100 °C).
In the delivered state, the set point potenti-
ometer is set to 0 %, i.e. it does not have any
effect on W1 set point (60 °C).
Additional points that apply:
Device with firmware 2.10 or lower:
Î The set point potentiometer only takes ef-
fect when the actual value originates
from a Pt 1000 sensor. In the combina-
tion with F05 - 1 (Current input active)
and F06 - 1 (Current input function = set
point), the set point potentiometer is not
active.
Device with firmware 2.11 or higher:
The set point can be adjusted even when us-
ing the current input.
Î The manually adjusted value at the set
point potentiometer for W1 is only used
for control if function block F12 in
28
TROVIS-VIEW is set to 1 (Automatic set
point potentiometer: manual setting ef-
fective above 10 %. The required setting
F12 - 1 is the default setting.
Î The set point W2 can only be changed
in TROVIS-VIEW.

blade screwdriver with 0.8 mm blade thick-
ness and 4.0 mm blade width.
1. Open front cover.
2. Set W1 set point as required at the set
point potentiometer (11 in Fig. 1).
Do not forget to check the automatic set
point potentiometer function.
3. Close front cover.
Function of automatic set point potentiome-
ter
Î Any setting below 10 % at the set point
potentiometer is ignored by the control-
ler. The controller uses the W1 set point
from the parameter list (TROVIS-VIEW
software) for control.
Î Any setting above 10 % at the set point
potentiometer is used by the controller

100 % of the measur-
ing range (default set-
