FLM-420-I2-E Input interface module type in-built | Installation manual
i
NOTICE! Installation must only be performed by authorized and specialized personnel!
WARNING! Live components and stripped cable! Risk of injury from electric shock. The
!
system must be current-free during connection work.
CAUTION! Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
Functional description
FLM-420-I2 Input interface modules provide three monitoring functions:
1. Monitoring a line with EOL resistor for standby or triggering (interruption/short circuit)
2. Monitoring a potential free contact for "open" and "closed" states
3. Voltage monitoring between 0 and 30 V DC.
The FLM-420-I2-E type in-built can be flush mounted in standard device boxes in accordance with EN 60670 (e.g. in
standard switching programs); alternatively, it can be installed in the devices (see Figure 6 to Figure 8, page 7).
Address setting
Address setting is carried out using the 8 DIP switches and a suitable pointed object (see Figure 1 to Figure 4,
page 3 and the following tables).
It is not permitted to use different operating modes in the same loop/stub/T branch next to each other!
Address (A) Operating mode
0 Loop/stub in LSN improved version mode with automatic addressing
1 ... 254 Loop/stub/T branches in LSN improved version mode with manual addressing
255 = CL Loop/stub in LSN classic mode (address range: max. 127)
Connection (see Figure 5, page 6)
