4.13 Safety Devices
Warning!
To prevent damage to the system, check that nothing is obstructing the movement
of the chair.
Chair safety devices
The safety switches stop the chair movement when there is an obstacle preventing the
movement. The safety switches protect the user from injuries in case of accidental mis-
use.
If the safety switch is activated, remove the obstructing object and continue working.
4.14 Temperature Limiters
The transformer is equipped with a temperature limiter. It prevents the temperature from
rising above predefined levels. This can happen if the chair is operated excessively with-
out adequate pauses.
The lift motor is equipped with software which measures active versus idle time. If the limit
ratio is exceeded, operation is stopped for a certain period of time.
4.15 Programmed Safety Limits
The product logic stops movement before the mechanical limits are reached. The pro-
grammed safety limits are intended to protect the device against breakage.
