CPMA a n d CPMB
• Button UP: The telescopic pillars CPMA and CPMB ex-
tends.
• Button DOWN: The telescopic pillars CPMA and CPMB re-
tracts.
On the operating device is a green LED indicating normal
operation.
The telescopic pillars CPMA and CPMB move until the but-
ton is released or the end position is reached. The stopping
of the movement is a “soft stop”. Therefore the traveling dis-
tance of the telescopic pillar from releasing the button until
stop is related to the speed and force direction.
The telescopic pillars will stop if buttons Up and DOWN are
pressed at the same time.
NOTE
Excessive current consumption, unusual noises or an unwanted
downward movement, indicate damage to telescopic pillars
CPMA and CPMB. Cease operation and inform the manufacturer
responsible for carrying out inspection.
