1000
2-10 Vdc Direct Acting
1010
10-2 Vdc Reverse Acting
For Figures 8 and 9 the following apply:
Allow 0.5 amps maximum for each device. Actuators and controller can share same transformer providing
1
the VA rating of the transformer is not exceeded and proper phasing is observed.
"T5" and "W" terminals are factory connected internally. Device is compatible with the 3-wire control system.
2
Use configuration DIP switches to select device functions: Direct acting function ( actuator stem moves
3
upwards with signal increases ) or Reverse acting function ( actuator stem moves downwards with signal
increases ).
NOTE:
Always turn power off before setting the DIP switches.
