3.6 Output Circuits

This page configures the usage of the output circuits provided by the IO-FEP2. Outputs 1 .. 10 refer to the photo-MOS outputs, normally dedicated to the WG switch - HPA muting circuitry. Outputs 11 .. 16 are the general purpose relay outputs of the IO-FEP2.

Following properties may be configured for each output:

• Type --- Defines the main purpose / type of the output:

  • UNUSED --- The output is not connected / not used
  • SW-INHIBIT --- The output is controlled by the software as a HPA mute output. It is not accessible for general purpose. (only available for the outputs 1..10)
  • HW-INHIBIT --- The output is controlled directly by the hardware HPA mute logic, not under software control. (only available for the outputs 1..10)
  • OUTPUT --- The output is configured as general purpose output, it's state may be controlled at the web interface or through one of the M&C interfaces.
  • TEMP-CTRL --- The output is configured as an output for a temperature control loop. The "State" page shows the actual state of this output like for a normal output, but the output cannot be controlled manually. The temperature control loop setup only offers outputs which are configured as TEMP-CTRL.

• Name --- When you activate an output at the 'Type' setting, the IO-FEP2 names this output as 'Oxx'. You may name the output in a more meaningful way by entering a circuit name at this place.

• Polarity --- 'NORMAL' polarity closes the contact for the output setting 'ON', 'INVERTED' polarity reverses this behaviour. The INVERTED setting frequently is used together with the software controlled inhibit logic in order to open the inhibit circuit while the switch moves. The polarity setting is not available if a photo-MOS output is configured as 'SW-INHIBIT'.

Please note, that the function of the outputs 1 ..10 first and foremost is controlled by the HW/SW control switch settings inside the IO-FEP2. Outputs which are selected as hardware controlled HPA mute outputs (the factory setting for all of these outputs) are not under software control and are automatically configured as HW-INHIBIT.
