    Construction 18. GAIN FACTOR The analogue inputs A1 and A2 have a standard range of 0 ~ +5Vdc. To use them externally, remove the jumper caps on SK2 and SK3. The internal 5V voltage source can only be used for testing purposes. When the input voltage is too low you can amplify it x4 / x15.

    Connection / settings 20. Connection / settings Internal / external voltage Analog signal adjust Address selection DC voltage 5 ... 30V Test LEDs Test buttons If the jumper is mounted, then you can use the internal voltage and adjust it using RV2/RV1. If the jumper is not mounted you must use the external voltage A2/A1.

  • Page 11: Test Procedure

    Connection / settings Select the correct address in the test program DIGITAL OUTPUTS : 8 open collector contacts, to be connected with suitable inputs. These exits function as ‘dry contact points’: you need an external voltage to control a component such as a LED or a relay switch.
  • Page 12 Test procedure The message "Card x connected" is displayed if the connection is successful You can now simulate the inputs via push buttons Inp1 through Inp5. The matching check box remains ticked off as long as you keep one of the push buttons pressed down. Always tick off the check box for the matching output if you wish to test a digital output.
