The interlocking configuration is channel spe-
cific, i.e. is done separately for each channel. A
general overview of the channel interlockings is
illustrated in figure 34 on page 37, which can be
used to draw up the interlocking scheme when
the channel interlockings are to be programmed.
The parameter selector push-button ↓ is repeat-
edly pressed until the LED marked INTER-
LOCK starts glowing. Select channels with the
channel selector push-button ∩.
A maximum of two interlockings can be selected
per channel. I.e. a channel can receive interlock-
ing signals from two different interlocking lines
(groups) or transmit one interlocking signal and
receive one interlocking signal. The first two
digits from the left in the display correspond to
the first interlocking function and the digits
three and four corresponds to the second inter-
locking function.
If the first interlocking function is to be taken in
use, the first digit from the left in the display
indicate the type of interlocking, that is:
0 = interlocking output
1 = interlocking input, reflash type A inter-
locked
2 = interlocking input, whole channel, return as
an acknowledged alarm
3 = interlocking input, whole channel, return as
a new alarm
See interlockings on page 16.
When the required interlocking function has
been selected, it can be linked to the chosen
interlocking line by moving the cursor to the
second digit from the left with the cursor control
push-buttons →. The chosen interlocking line
(1...8) is selected with the data value selector
push-button ↑. If no interlocking function is
needed, a - mark is selected in stead of the
number of the interlocking line. The selected
parameter values are stored in the memory by
pressing the enter command push-button.
The parameter selector push-button ↓ is repeat-
edly pressed until the LED marked MODULE
starts glowing. The cursor is moved to the first
two digits from the left of the display, using the
cursor control push-button →. The SPA bus
slave number (01...99) is selected for the annun-
ciator unit with the data value selector push-
The selection relating to the second channel
interlocking function is carried out in the same
way as the selection of the first interlocking
function, but in this case the third digit from the
left of the display indicates the type of interlock-
ing and the fourth digit states the corresponding
interlocking line.
IMPORTANT!
If more than three interlocking levels are used
(i.e. a channel that blocks a channel that blocks
a channel) the resolution of the time stamp of
the events will be effected.
The following example of an interlocking con-
figuration relates to the figure is on page 17.
At first INTERLOCK function is selected.
Channel 10 is called up.
The display is set to 010-, which is stored in the
memory.
Channel 10 now activates interlocking Line 1.
Channel 8 is called up.
The display is set at 2102, which is stored in the
memory.
Channel 10 now interlocks whole channel 8 (via
the interlocking line 1 ) at the same time channel
8 activates interlocking line 2.
Then channel 7 is called up.
The display is set at 110-, which is stored in the
memory.
Channel 10 now interlocks the reflash A of
channel 7 via interlocking Line 1.
Then channel 5 is called up.
The display is set at 120-, which is stored in the
memory.
Channel 10 now interlocks channel 8 which
interlocks the channel reflash type A of channel
5 via interlocking line 2.
button ↑. The chosen slave number is entered
into the parameter memory by pressing the
enter control push-button.
NOTE!
No slave number is needed if the annunciator
unit is not connected to a higher level system.
