STEP
From register 0 it is possible to enter the TEST mode, in which the start and operate
signals of the module can be activated one by one. The table below shows the
activation order and the corresponding indicator lit when a signal is tested.

For further information about the operation, see description "General characteris-
tics of D-type SPC relay modules".
A
Address code of the relay module, required by the serial communication system.
In addition, the following submenus are available in register A:
1. Selection of the data transfer rate, 4.8 kBd or 9.6 kBd, of the relay module. Default
setting 9.6 kBd.
2. Bus traffic counter indicating the operating state of the serial communication
system. If the relay module is connected to a system including a control data
communicator and the communication system is operating, the counter reading
is 0. Otherwise the numbers 0...255 are continuously scrolling in the counter.
3. Password required for remote setting. Settings cannot be changed over the serial
communication system unless a password (remote setting parameter V160) has
been given.
4. Selection of main and second settings (0 = main settings, 1 = second settings).
Default setting 0.
5. Selection of operate time for the circuit breaker failure protection, setting range
0.1...1.0 s. Default setting 0.2 s
When the display is dark, press the STEP push-
button for 1 second to go to the beginning of the
display menu. To go to the end of the display
menu, press the STEP push-button for a short
moment only (<0.5 s).
The values stored in registers 1...11 are cleared
by pressing the push-buttons RESET and PRO-
GRAM simultaneously, by a command V102
over the serial communication system or by an
external control signal BS1, BS2 or RRES. The
registers are cleared by failures in the auxiliary
power supply to the module. The setting values,
the address code, the data transfer rate and the
password of the relay module are not affected by
supply voltage failures. Instructions for specify-
ing the address code and the data transfer rate of
the relay module are given in the description
"General characteristics of D-type SPC relay
modules".
