Register/ Recorded information
STEP
0 Display of blocking signals and other external control signals. The digit at the
extreme right indicates the state of the blocking of the undervoltage stage.
The following states are indicated:
0 = no blockings
2 = tripping of the undervoltage stage blocked
The middle digit of the register is always a zero. The leftmost green digit indicates
the state of the remote reset input, if any.
The following states are indicated:
0 = remote reset control input not energized
1 = remote reset control input energized
From this register it is possible to move on to the TEST mode, where the starting and
tripping signals of the module can be activated one by one. For further details see the
description "General characteristics of C-type relay modules".
A The address code of the measuring relay module, required by the serial communi-
cation system.
Submenu 1: Selection of the data transfer rate.
Submenu 2: Bus traffic monitor. If the relay module is connected to a data
communication system and the communication is operating, the counter reading of
the bus traffic monitor will be 0. Otherwise the numbers 0...255 are continuously
rolling in the counter.
Submenu 3: Password required for remote setting. The password given in the setting
mode of a submenu must always be entered via the serial communication before the
settings can be altered remotely.
When the display is dark, the register can be re-
entered by pressing the STEP push-button.
The registers 1...8 are cleared by pressing the
push-buttons STEP and RESET simultaneously
or via the SPA bus with the command V102.
The registers are also cleared if the auxiliary
power supply to the module is interrupted. The
address code of the relay module, the data
transfer rate of the serial communication system
and the password of the module are not affected
by voltage failures. The instructions for setting
the address and the data transfer rate are given in
the manual "General characteristics of C-type
relay modules".
At the initial state when none of the stages has
started, the reading of register 1 is "000" and
that of register 3 is "– – –"
