Voltage Process Input Procedure
Equipment
•
Precision voltage source, 0 to 10V minimum range, with 0.001V resolution.
Input 1 and 2 Setup and Calibration
1.
Connect the correct power supply to terminals 8 and 9 (see Series 96 User’s Manual).
Input 1
2.
Connect the voltage source to terminals 4 (+) and 6 (-) of the controller.
3.
Enter 0.00V from the voltage source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 1, 0V [A`0u] (Calibration 1 Menu) to [`yES]. Press
the Advance Key ‰ to store the 0.00V input and move to the next prompt.
4.
Enter 10.00V from the voltage source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 1, 10V [A10u] (Calibration 1 Menu) to [`yES]. Press
the Advance Key ‰ to store the 10.00V input and move to the next prompt.
Input 2
5.
Connect the voltage source to terminals 1 (-) and 3 (+) of the controller.
6.
Enter 0.00V from the voltage source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 2, 0V [b`0u] (Calibration 2 Menu) to [`yES]. Press
the Advance Key ‰ to store the 0.00V input and move to the next prompt.
7.
Enter 10.00V from the voltage source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 2, 10V [b10u] (Calibration 2 Menu) to [`yES]. Press
the Advance Key ‰ to store the 10.00V input and move to the next prompt.
8.
Rewire for operation and verify calibration.
Current Process Input Procedure
Equipment
•
Precision current source, 0 to 20mA range, with 0.01mA resolution.
Input 1 and 2 Setup and Calibration
1.
Connect the correct power supply to terminals 8 and 9 (see Series 96 User’s Manual).
Input 1
2.
Connect the current source to terminals 5 (+) and 6 (-).
3. Enter 4.00mA from the current source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 1, 4mA [A`4A] (Calibration 1 Menu) to [`yES]. Press
the Advance Key ‰ to store the 4mA input and move to the next prompt.
4.
Enter 20.00mA from the current source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 1, 20mA [A20A] (Calibration 1 Menu) to [`yES].
Press the Advance Key ‰ to store the 20mA input and move to the next prompt.
Input 2
5.
Connect the current source to terminals 1 (-) and 2 (+).
6.
Enter 4.00mA from the current source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 2, 4mA [b`4A] (Calibration 2 Menu) to [`yES]. Press
the Advance Key ‰ to store the 4mA input and move to the next prompt.
7.
Enter 20.00mA from the current source to the controller. Allow at least 10 seconds to
stabilize. Set Process Calibration 2, 20mA [b20A] (Calibration 2 Menu) to [`yES].
Press the Advance Key ‰ to store the 20mA input and move to the next prompt.
8.
Rewire for operation and verify calibration.
