From this register it is possible to enter the TEST mode, in which the output signals
of the relay module can be activated one by one. The setting operation indicators
and their corresponding output signals are presented below.

The CB closing signal can also be activated in the TEST mode.When all setting
indicators are flashing, the CBCS signal can be activated by pressing the push-
buttons STEP and PROGRAM simultaneously.
BEFORE STARTING THE TEST PROCEDURE, MAKE SURE THAT IT IS
SAFE TO CLOSE THE CIRCUIT BREAKER!

A
Address code of the AR relay module, required for serial communications. Register
A has four subregisters with the following contents:
1. Selection of the data transfer rate: 4800 or 9600 Bd (4.8 or 9.6 kBd).
2. Bus traffic monitor. If the relay module is connected to a data communication
system and the communication is in operation, the value of the monitor is 0.
Otherwise the numbers 0...255 are rolling.
3. Password required for remote setting.
4. Selection of the operation mode for the AR module. When the register value is
one (1) the AR program is out of use and when it is zero (0) the AR program is
in use.
The registers are reset by pressing the RESET
and PROGRAM push-buttons simultaneously.
The registers, the address of the relay module,
the data transfer rate and the password are not
affected by voltage failures. Instructions for set-
ting the address and the data transfer rate are
given in the document "General characteristics
of D-type relay modules".
