Register/ Recorded information
STEP
0 Display of the state of the basic angle control signal BACTRL and other external
control signals. The rightmost digit in the display shows the state of the blocking
signals BTS1 and BTS2. The following states are indicated:
0 = no active incoming blocking signal
1 = operation of stage Iϕ> blocked
2 = operation of stage Iϕ>> blocked
3 = operation of both stages blocked
The state of the basic angle control signal BACTRL is displayed by the mid digit of
the green part of the display. The alternative states are:
0 =BACTRL in the 0 state, i.e. the operation characteristic is I
control of the operation characteristic has been selected
1 =BACTRL in the 1 state, i.e. the operation characteristic is I
control of the operation characteristic has been selected
The leftmost green digit indicates the state of the remote reset control input, if any.
The following states are indicated:
0 = remote reset control input not energized
1 = remote reset control input energized
From this register one can move on to the TEST mode, where the start and
operation signals of the module can be activated one by one in order to test the
output relays. For further details see the description "General characteristics of C
type relay modules".
A Address code of the protection relay module, required by the serial communication
system. The address code is set to zero when no serial communication is to be used.
The subroutines of this register are:
1) Selection of data transfer rate for the serial communication. Selectable values:
300, 1200, 2400, 4800 and 9600 Bd. Default value 9600 Bd.
2) Bus communicaton counter. If the module is connected to a data communica-
tion device and the communication system is working the communication
counter shows 0 (zero). If the communication is interrupted the numbers
0...255 is scrolling in the counter.
3) Password required for the remote control of the relay settings
The registers 1...8 are reset by pressing the push
buttons STEP and RESET simultaneously or
over the SPA bus by means of the command
V102. The registers are also reset if the auxiliary
power supply of the relay module is interrupted.
The address code of the relay module, the data

transfer rate of the serial communication system
and the password are not erased by a supply
interruption. The instructions for setting the
address and the data transfer rate are given in the
manual "General characteristics of C type relay
modules".
