6.5.1 Derating
nector
M12 x 1, 8-pole The maximum duty cycle of the valve depends on the maximum
ambient temperatures and the current required by the stepper motor.
24 V DC ±10 % -
The derating curve can be used to indicate the maximum duty cycle
residual ripple < 10 %
permissible at the corresponding ambient temperature. By switching on
max. 12 W
the low power function a higher duty cycle can be achieved (Warning:
during low power function, max medium pressure is reduced; if violated
approx. 1 W
Valve will not move or malfunction).
