If a key is rejected at a terminal, this can have various causes. To narrow down this cause, there are error codes that the terminals can output. Here you can find out how to read these out if necessary.

The error code can be read out in both DG1 and DG2 using the rejected transponder. To do this, hold the rejected transponder against the terminal beyond the rejection signal (red LED lights up twice and the terminal beeps twice). You will then receive a further signal sequence that can be evaluated with the appropriate error code list.

IMPORTANT! The option to read out error codes was not available from the start. There are therefore some DG1 terminal types for which an error code cannot be read out. (e.g. older DTSH models)

An alternative to reading out the error code is to hold the rejected transponder against the terminal and then read out the error code using the MDU (handheld device) via the “Terminal Info”. After reading out the “Terminal Info”, scroll down using the adjusting wheel until you see the line “Last error code”. The last two digits of this line, which are separated by a dot (e.g. 4.2), correspond to the error number from the error code list.

This option is only possible with the DG2 terminal.

Unlike all other Dialock terminals, the Dialock DT510 knob profile cylinder can issue additional error messages whenever something is wrong with the connection or communication between the electronic knob and the profile cylinder.

However, these error messages are only output when the terminal has accepted a valid key and should then normally engage or disengage. Therefore, the output of these error messages is always initiated by a single beep (key accepted as valid).

Status signals indicate the current operating status of the terminal. These usually occur immediately as soon as a transponder is held against the reader and only then is the locking process started.

These signals appear, for example, when the battery power decreases.
