7.0 Operation
7.1 Safety
DANGER
Risk of crushing!
Actuator may cause serious injuries while moving.
Therefore:
• Ensure that there are no persons in the stroke area of the actuator
while in operation.
• Take note of maximum permissible operating data for the actuator
(⮑ 11.0 Appendix, page 27).
• Never tamper with the elements that are connected to the actua-
tor while the actuator is in operation.
CAUTION
Risk of injury through contact with the hinge head!
Therefore:
• Do not let objects or body parts come in contact with the hinge
head of the actuator.
CAUTION
Material damage due to static and dynamic overload of the
actuator!
Therefore:
• Adhere to maximum permissible operating data for the actuator
(⮑ 11.0 Appendix, page 27).
• Never exceed nominal load.
• Never tamper with the elements that are connected to the actua-
tor while the actuator is in operation.
CAUTION
Actuator may be damaged if liquids penetrate the actuator during
extension and retraction. Keep liquids away.
CAUTION
Material damage through overheating!
Therefore:
• Only use control integrated thermal switch.
• Never exceed nominal load (⮑ 11 Appendix, page 27).
• Always adhere to idle times and operating times (⮑ 11 Appen-
dix, page 27).
7.2 Action before
operation
Ensure that there are no persons or objects in the stroke
area of the actuator.
7.3 Action during
operation
7.3.1 Normal operation
During normal operation, the linear actuator lifts and lowers
the elements that are connected with the CAHB-2…linear
actuator via the hinge head.
For all CAHB-20E and the CAHB-21E and CAHB-22E with-
out Limit switches option, the clutch will activate if the linear
actuator is completely extended or retracted. In case of op-
tional limit switches or external limit switches installed on
the application, the actuator will stop before to reach the
mechanical end stop and the clutch activation.
Use only the actuator within the specified limits.
Don’t place any of your body, hands, or arms near moving
components.
CAUTION
Material damage through overheating!
Therefore:
• Only use control integrated thermal switch.
• Never exceed nominal load.
• Always adhere to idle times and operating times (⮑ 11 Appen-
dix, page 27).
CAUTION
Material damage due to incorrect set up of the limit switch!
Therefore:
• Select limit switch or other electrical component that is adequate
for the rating voltage and current of linear actuator (⮑ 3.0 Tech-
nical data, page 9).
• Consider the inertia of the movement of the linear actuator while
setting up the position of the limit switch.
• Prior to starting work, run a function test to confirm that the exter-
nal limit switch is operating properly.
