FLM-420-I2-D
Safety Notes
NOTICE!
Installation must only be performed by authorized and specialized personnel.
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:
- Monitoring a line with EOL resistor for standby or triggering (interruption/short circuit)
- Monitoring a potential free contact for "open" and "closed" states
- Voltage monitoring between 0 and 30 V DC.
The FLM-420-I2-D is installed on a DIN rail in accordance with EN 500022 with enclosed adapter (see Figure 1,
Page 4, Removal: Figure 2, Page 5).
Address Setting
Fit the rotary switches in the required position using a pan head slotted screwdriver
(see Figure 3, Page 6).
Address (A) Operating mode
0 0 0 Loop/stub in LSN improved version mode with automatic addressing
0 0 1 - 2 5 4 Loop/stub/T-taps in LSN improved version mode with manual addressing
CL 0 0 Loop/stub in LSN classic mode (address range 127 max.)
2 5 5 - 2 9 9 Invalid address range (error message on fire panel)
Connection
See Figure 4, Page 6.
