Decoder PCB | Siemens RL-854 guide

RL-854 Radio Control Unit
Type I, Style A	Operation

Incremental Relay Option

(contd.)

See Figure 6. If you want to change the relay operation from individual to incremental, disconnect diodes D3, D4, and D12 on Decoder PCB. Cut these diodes from the Decoder PCB using a diagonal cutter tool.

WARNING: Make sure power to the RL-854 has been disconnected before attempting to cut the diodes.

To change relay operation from INDIVIDUAL to INCREMENTAL, cut wires on diodes D3, D4, and D12.
