Relay Trigger Modules - Ahlborn ALMEMO 710 Operating Instructions Manual

cables and their connection to devices are described in detail in the Manual
5.2. Other modules for networking the devices are described in detail in the
Manual 5.3. All available interface modules can be connected to socket A1 (2);
this is with the exception of cable ZA 1999-NK, which is used for networking
extra devices; this must be connected to socket A2. In the menu under the
socket concerned e.g.: A1
Variant RS232
Baud rate 9600 baud
The baud rate can also be modified here via a selection box.

13.5.2 Relay trigger modules

Whereas, for the purpose of addressing peripheral devices for relays and trig-
ger inputs (see Manual 5.1.2/3), old V5 modules (ZA1000-EAK) offer only one
function variant (see Manual 6.6.4), the new V6 relay trigger cables and the re-
lay trigger analog adapter (ZA 8006-RTA3) offer up to 10 relays or options with
2 trigger inputs or up to 4 analog outputs. Relays, trigger inputs, or analog out-
puts can be individually configured regarding their function variant. These
modules can be connected at any of output sockets A1 to A3 (2). To ensure
that all elements can be addressed, each of these sockets has been assigned
10 port addresses.
Socket Connection
A1 V6 output modules at socket A1
A2 V6 output modules at socket A2
In the menu ´Output modules´ first the desired output module is selected; this
gives access to ´Port list´ and ´Port settings´. Here the elements can be indi-
vidually selected and their functions programmed. (see Manual 6.10.9)
Relay addressing
On leaving our factory relays are set basically as follows :
Semiconductor
Semiconductor
Semiconductor
Relay addressing can be configured to the following variants :
Total alarm
Assigned
Total alarm Max
Total alarm Min
Driven
When relays are assigned to limit values the variant ´Assigned´ is configured
automatically. (see 13.2.8). Power failure can be detected more easily if relay
addressing is inverted; i.e. in the absence of current (power failure) the relay
drops out, the contacts close, and an alarm is triggered automatically.
