Operation Manual SUPREMA
6. Startup
The relay driver outputs are configured in the “Setup/Relay Outputs” menu. The individual options
are described below.
Note: The name of the menu or of the input or option field used by the PC operating
software is given in parentheses.
Option field “Relays” (“Output number”): Choose the number of the relay driver output to be
configured.
Option field (beside “Relays” field) (“kind of switching”):
Normally energised When having been set (alarm, failure), the relay driver output gives out
a LOW signal, i.e. the connected relay is de-energised (normally
energised principle)
Normally de-energised (Relay is de-energised) When having been set (alarm, failure), the
relay driver output gives out a HIGH signal i.e. the connected relay is
energised (normally de-energised principle)
Note: When the relays are inhibited by using the LOCK connection on the MRC-TS
module, the switching direction selected in the “Normal” option field must agree
with the switching direction set via the bridge BR1 on the MRC-TS module.
Remember that the relays can be inhibited via the LOCK connection only as a
block of 40, whereas the “open circuit/closed circuit” field makes it possible to
select a value for each individual relay.
(see section 5.3.7 Configuration of the
MRC-TS-Module)
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.”). (PC operating program: In
addition, the corresponding input parameters which were entered in the “Setup/Measure Points”
menu are shown the “Tag” and “Marking” columns.)
Use the control fields [Ï] and [Ð] to scroll through the list of inputs (select the cursor key and
then press Return). (PC operating software: Use the scroll bar.)
Attention: 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 numbers 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.
