Parallel operation of actuators

3-position actuators must have one specific controller each, refer to "Connection
diagrams" (page 82).
Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA.
Modulating actuators have an input impedance of 100 kΩ.
The Modbus converter is designed for analog control on 0..10 V on the actuator
side.
Note: Keep the setting of the analog signal on the actuator as is (switch 1 to
"OFF"), adjustment is not allowed.
The actuators are factory-set to equal-percentage characteristic curve.
Note: The DIL switch (actuator-internal changeover of characteristic curve) must be
set to "log" (switch 2 to "OFF").
