C. Setting the Switch Points of Output
At this point make sure all electrical connections have been made properly and apply power to the con-
troller. Each controller has the same controls and used the same set-up procedure. To set the output 1
switch point:
1. Turn Set Point potentiometer 1 (Set 1) fully counterclockwise.
2. Move the piston to the position where output 1 should switch on and off.
3. Observe Set Point 1 LED.
4. Rotate Set Point potentiometer 1 (Set 1) clockwise until Set Point 1 LED just changes state (on to
off or vice-versa).
Follow the same procedure (using Set Point 2 controls) to set the switch point of output 2.
1. Turn Set Point potentiometer 2 (Set 2) fully clockwise.
2. Move the piston to the position where output 2 should switch on and off.
3. Observe Set Point 2 LED.
4. Rotate Set Point potentiometer 2 (Set 2) counterclockwise until Set Point 2 LED just changes
state (on to off or vice-versa)
III. SCALABLE OUTPUT
There are two different output types: 0V to +10V and 4mA to 20mA. Each type is available with AC or
DC power input. Each output is scalable. For detailed information on scaling, refer to Section III B.
A. Output Boundaries and Actions
Standard output operation produces minimum analog output at minimum cylinder extension and maxi-
mum analog output at maximum extension. FIGURE 6 plots ideal analog output versus cylinder exten-
sion.
