ADEPT 10338-00190 Serial Link Controller
In the current controller, the current command value is moreover modulated with the clock generator signal [10] (frequency can be programmed using the DIL switch 2)). In the valve solenoid, the clocked actual current value acts like a constant current with superimposed dither signal. Type VT-VSPA1-1 has measuring sockets for the internal command value and the actual value.
The following is true for the command value:
+6 V ≙ 100 % The following is true for the actual value: 1 mV ≙ 1 mA The "ready for operation" signal is output and the "H2" LED on the front plate (with VSPA1-1) or the "H2" LED (with VSPA1K-1) is illuminated if: ▶ there is no short-circuit of the solenoid conductors and no overload of the output stage, ▶ a command value is available (cable break detection), ▶ there is no cable break of the solenoid conductor.
