C. Setting Scalable Output
The procedure used to set the two boundaries is as follows:
1. Setting the Offset (minimum output point)
a. Move the piston to the minimum output wanted.
b. On 0-10 VDC Controllers: Place a voltmeter across Terminal 6 (Analog Out) and 7 (Analog
GND). On 4-20 mA Output Controllers: Place an ammeter in series with the load to be driven.
Current sources from Terminal 6 (Analog Out) and returns to Terminal 7 (Analog GND).
c. Adjust the offset potentiometer until the respective minimum output is reached.
2. Setting the Gain (distance between minimum and maximum analog output)
a. Move the piston to the maximum output point wanted.
b. On 0-10 VDC Output Controllers: Place a voltmeter across Terminal 6 (Analog Out) and 7
(Analog GND). On 4-20 mA Output Controllers: Place an ammeter in series with the load to
be driven. Current sources from Terminal 6 (Analog Out) and returns to Terminal 7
(Analog GND).
c. Adjust the gain potentiometer until the respective maximum output is reached.
This completes the scaling procedure. At this point the unit is set-up and ready for use.
IV. TROUBLESHOOTING
The controllers operate on very fundamental principles which greatly reduce the likelihood of problems. If
a problem arises, there are several items to check before consulting your distributor.
1. Verify that all connections have been made properly.
2. Verify that the required power source is working.
3. Verify that the wiper signal (0 to 10 VDC) at Terminal 4 is changing with cylinder movement.
If all of these check out, contact your distributor for further assistance.
