Solid state PCB - connection of limit switches
When the RF14XU limit switches are connected to the TB12, only
control signals are switched. When the limit switches are connected
to TB16, the solenoid load (current) is switched. It is recommended
not to use the TB16 connections if the load exceeds appr. 30W. If so,
TB16 no. 1-3 and 2-4 are jumpered and the limit switches connected
to TB12. If TB16 is used for limit switches, TB12 no. 1-3 and 2-4 must
be jumpered.
Note !
Limit switch connections not used must be jumpered
