The force on the handwheel was calculated for one-handed operation. With two-hand operation, the value per hand is
halved. The maximum force may be exceeded by 20% in manual mode.
The direction of rotation and the maximal handwheel torque are written on the handwheel label, as shown on figure above.

Adjusting of Failsafe speed
General:
Schiebel CM Failsafe actuators are equipped with an adjustable passive eddy current brake, by which it is possible to
change the failsafe speed. When delivered the failsafe speed is set to minimum.
After mounting the actuator to valve and test run, failsafe speed can be increased if necessary.
CAUTION:
Valve or piping may be damaged due to high actuating speed!
WARNING: All adjustment work may only be performed with the actuator disconnected from the power
supply. Due to this requirement, the actuator has to be in the fail-safe position! Any powering up must
be ruled out during maintenance!
WARNING: When working in potentially explosive areas, heed European Standards EN 60079-14 “In-
stalling Electrical Systems in Explosion Endangered Areas” and EN 60079-17 “Inspection and Mainte-
nance of Electrical Installations in Explosion Endangered Areas”.
