1 )
Pause time with change of rotation 0.4 s.
2 )
Increased wear with continuous operation of the motor.
3 )
limited gas seal
4 )
Impurities (e.g., fluff etc.) should be pre-filtered, otherwise the function of the valve could be impaired.
5 )
At 24 V DC smoothed. Pulsed drive increases the rotation time (see also
8)
)
6 )
dependent on pressure/load
7 )
Higher currents considerably reduce the service life!
8 )
Higher temperatures limit the max. power loss of the potentiometers.
9 )
min. pulse length (the min. pulse length increases at no-load/ at pressure/load):
for LC: approx. 100 ms / for Mod.: approx. 100 ms
