switching direction set via the bridge BR1 on the MRC TS module. Remember that the relays can
be inhibited via the LOCR connection only as a block of 40, whereas the “open circuit/closed cir-
cuit” field makes it possible to select a value for each individual relay. (see section 10.3)
Check box “new Alarm” (i. e. actual alarm): When this field is set, the relay output selected can be
set to “normal” status by pressing the <ACKNL> key, in spite of the value having been outside the
limits.
Configuration Matrix:
Here is where you assign the measure point no. and the setting conditions to be fulfilled to the
selected relay output.
The input numbers are shown in the column “Channel” (“No.”) . ("SUPREMA Manager": In addi-
tion, the corresponding input parameters which were entered in the “Setup/Measure Points”
menu are shown the “Tag” and “Marking” columns.)
Use the control fields [

] and [

] to scroll through the list of inputs. ("SUPREMA Manager": Use
the scroll bar.)
NOTE: When connecting the sensors to the rack, space constraints allow only every other MAI
module slot to be used. This means that the input numbers are 9–16, 25–32, etc. The input num-
bers 1–8, 17–24, etc., which are not actually present still appear, however, in the setting matrix.
In no case may any settings be made here.
For each input, it is possible to select any one of the following conditions: “1
st
alarm”, “2
nd
alarm”,
“3
rd
alarm”, “4
th
alarm”, “failure”, or “locked”. In the “Voting” option field, you can link the individual
setting conditions logically together.
Check box “1
st
-4
th
Alarm”: If the alarm condition (limit value) for the assigned input is fulfilled, then
the selected setting condition is fulfilled. Checking the check box selects the condition.
Check box “Failure”: This setting condition is fulfilled when a failure has occurred at the assigned
input. Checking the check box selects the condition.
Check box “Locked” : This setting condition is fulfilled when the assigned input is inhibited. This
condition is selected by checking the check box.
Option field “Voting”: Here links can be made between the various setting conditions selected in
the setting matrix. The number of setting conditions selected for the chosen relay driver output is
shown after the “/” (in the field “Alarm(s) of”).
In the option field “Voting”, you enter the number of conditions which must be fulfilled for the set-
ting of the relay driver output.
The following types of links can be set up in this way:
