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
