CAMT 20
7.5 Actions during
operation
7.5.1 Normal operation
During normal operation, the linear actuator lifts or lowers
elements connected to it via the front and rear attachment.
The linear actuator is driven via an external control unit and
the corresponding operating device (refer to chapter ⮑ 11.2
Approved Accessories, page 41).
Use directional buttons UP and DOWN on the operating de-
vice to operate CAMT.
• Button UP: CAMT extends.
• Button DOWN: CAMT retracts.
The CAMT moves until the button is released or the end po-
sitions are reached. When the end position is reached, an
end limit switch is triggered and power to the DC motor is
cut off. An end position can also be defined by a pre-pro-
grammed position in the control unit triggered by the en-
coder signal from the CAMT linear actuator.
CAUTION
Excessive current consumption, unusual noises or an unwanted
movement indicate damage to the linear actuator CAMT. Cease
operation of the CAMT and contact the manufacturer responsible
for carrying out inspection.
7.5.2 Operate options
It is recommended not to exceed the duty cycle defined in
the Technical Details.
Details of specific operations can be found in the following
sections:
• Installation and first operation
• Maintenance
• Malfunctions
• Dismantling
7.6 Emergency
disengagement
In hazardous situations, all movements of the device must
be stopped as quickly as possible and the power supply
turned off.
Procedure in hazardous situations:
1. Immediately engage emergency shut-off, if present, or
cut off power to actuator (refer to chapter ⮑ 7.6.1 Shut
down, page 34).
2. Evacuate people from the hazard zone, initiate first aid
measures.
3. Notify doctor and fire department, if necessary.
4. Notify responsible person on-site.
5. Keep access paths open for rescue vehicles.
6. Based on severity of emergency, notify the authorities if
necessary.
7. Order specialized staff to repair malfunction.
WARNING
Do not restart until all persons are outside the hazard zone.
8. Check the device and application that uses the device
prior to restarting the operation. Ensure that all safety
equipment is installed and fully functional.
NOTE
The linear actuator CAMT does not have an on/off switch and
must be disconnected from external control unit. Only this
measure will de-energize the CAMT.
NOTE
For medical equipment the application in which the linear
actuator CAMT is installed must provide an emergency stop
switch or isolation from the mains supply on all poles.
7.6.1 Shut down
1. Pull the power line plug of the control unit out of the
power outlet.
2. Pull the DIN-8 plug of the device’s cable out of the con-
trol unit connection socket.
