With the setting of the PWM frequeny, take into account the diffe-
rent dynamics of the spring mass systems of the valves;
in principle, you can drive the valve with any of the control
frequencies listed above - the values given provide the optimum
with regard to hysterisis and noise emission (in general, the rule is:
lower frequency = less hysterisis, but more noise development).
If you notice an oscillation tendencyof the system in an application
with high medium pressure, it is recommended that you use the
next higher control frequency as shown in the table above.
Whenever possible, connect two earth cables to Terminal 3 when
wiring the Type 1094-PMR cable plug electronics (one cable for
the earthing of the operating voltage, the other for the earthing of
the standard signals and monitor signals).
When screwing the appliance socket to the coil, make sure that
the flat seal is well seated!
