6.10 Manual operation
6.10.1 Handwheel
The handwheel (red knob, see Fig. 2) is used to move the actuator stem when the power has
been disconnected. Do not use the handwheel while the actuator is running.
6.10.2 Command mode
A memory pen (order no.1400-7697 or order no. 1400-9753) can be configured in
TROVIS-VIEW to be a command pen. The command pen allows the actuator stem to be
moved to the open and closed positions.
Note:
The action of retracting/extending the actuator stem on inserting the command pen
has absolute priority. The input signal is overridden.
The configuration of the memory pen is explained in section 8.2.4.
