DigiLink - Troubleshooting DE DigiLink

As always make sure the DigiLink is on line and at the correct address by checking bus scan and Panel and Switch Types also confirm that it is set to be a 14 button switch. In the case of multiple DigiLinks confirm that you working with the correct DigiLink by reading the address. Confirm if they are using ground 8 connection and if they are is it on or off.

 

The easiest way to test the DigiLink is to take a piece of wire and short between system ground and the inputs to confirm that the card activates the programmed relays. If you look at the card there is a GND just to the left of the 5v on the screw terminal that has inputs 1-3, if you take a wire and hold it to the GND and then touch the inputs 1-14 they should not only turn the LED’s on for each input as you touch that input but the relay associated with the input should activate according to the programming.

 

The card can also be tested by pushing the appropriate button for the inputs but a more through test is with the wire because this also includes the connector.

 

If the DigiLink is being used with dry contact type of device i.e. an occ-sensor or a regular wall switch then the DigiLink needs to be set to maintain so when you short the GND to an Input then the button should turn on and stay on as long as you hold the short to the input.

 

If this test does not confirm that the DigiLink is working correctly check the programming and power cycle the card. If the DigiLink is programmed correctly and power cycling did not cure the problem replace the DigiLink

 

If you can confirm that the DigiLink is working correctly by this method then the problem is being caused by something other than the DigiLink. Make the installer check out their control device the problem will be found in their equipment. It is not hard to check a occ-sensor or switch. Use a ohm meter and measure the from the wire coming from the DigiLink or switch to confirm that the contact closer coming from the control device is actually opening and closing, this should be done with the wires disconnected from the DigiLink to confirm that you are only checking the control device.  

 

Remember that if the above test show that our DigiLink is working then it is working and the problem is in the dry contact equipment or the input wiring.
