What settings or tests can I make in the Service level?
In this level you can test the display, keys, switching outputs, and so on.
The matrix display shows alternately "Code-NR." and "0000". Use the <Enter> key to move one digit to the left, use the arrow keys to set "7", and press the <Enter> key 3 times.
All the displays will be lit up.
The keys that are pressed will be indicated in plain text in the matrix display (display 3).
The matrix display indicates "00000000". Setting the logic inputs to "0" (e.g. by closing a contact) changes each one of the zeroes to a "1", e.g. "11111111" (depending on the version fitted).
Outputs 1 - 6 <Enter> à For switching outputs (relays, solid-state relays, logic): the outputs can be switched by using the arrow keys. When the keys are released, the relays drop out again.
This test function has no effect for analog outputs or logic inputs.
The matrix display shows alternately "Temp" and the cold-junction temperature measured at the moment (for thermocouples, in the back panel).
The device shows the count of the number of commands received in the upper display (display 1).
In the middle display (display 2), the device shows the count of the number of commands sent.
On devices that only communicate via the setup program, both counts must be identical. The <Enter> key can be used to reset the count to "0".
