Watlow Series SD31 ■ 47 ■ Chapter 9 Factory

Current Process Input Procedure

Equipment

• Precision current source, 0 to 20 mA range, with

0.01 mA resolution.

Input Setup and Calibration

1. Connect the correct power supply to terminals 1

and 2 (see Chapter Two).

2. Connect the current source to terminals 11(-) and

8(+).

3. Enter 4.00 mA from the current source to the con-

troller. Allow at least 10 seconds to stabilize. Press

the Down Key ¯ until the Input Calibrate 4 mA

parameter, [``A;4] appears. Press and hold the

ß Key and change [`~no] to [`yES] by press-

ing the Down Key ¯. Release the ß Key and

press the Down Key ¯ to store the 4 mA input and

move to the next parameter.

4. Enter 16.00 mA from the current source to the con-

troller. Allow at least 10 seconds to stabilize. At the

Input Calibrate 16 mA parameter, [`A;16] , press

and hold the ß Key and change [`~no] to

[`yES] by pressing the Down Key ¯. Release the

ß Key and press the Down Key ¯ to store the

16 mA input and move to the next parameter or

press the Infinity Key ˆ to exit the Factory Page.

5. Rewire for operation and verify calibration.

Process Output Procedures

Equipment

• Precision volt/ammeter with 3.5-digit resolution.

Output 1 Setup and Calibration

1. Connect the correct power supply to terminals 1

and 2 (see Chapter Two).

Volts

2. Connect the volt/ammeter to terminals 7 (-) and 6 (+).

3. Press the Down Key ¯ until the Output 1 Cali-

brate 1 V parameter, [01;1u] appears. Press and

hold the ß Key and change [`~no] to [`yES] by

pressing the Down Key ¯. Release the ß Key.

The voltage output value appears in the display.

Press the Up ¿ or Down Key ¯ to adjust the dis-

play value to match the value from the volt/amme-

ter. The unit should stabilize within one second. Re-

peat until the volt/ammeter reads 1.00 V, ±0.1 V.

Press the Down Key ¯ to store the value and move

to the next parameter.

4. At Output 1 Calibrate 9 V parameter [01;9u], press

and hold the ß Key and change [`~no] to

[`yES] by pressing the Down Key ¯. Release the

ß Key. The voltage output value appears in the

display. Press the Up ¿ or Down Key ¯ to adjust

the display value to match the value from the

volt/ammeter. The unit should stabilize within one

second. Repeat until the volt/ammeter reads 9.00 V,

±0.1 V. Press the Down Key ¯ to store the value

and move to the next parameter or press the Infini-

ty Key ˆ to exit the Factory Page.

5. Rewire for operation and verify calibration.

Milliamperes

6. Connect the volt/ammeter to terminals 7 (-) and 5

(+).

7. Press the Down Key ¯ until the Output 1 Cali-

brate 4 mA parameter, [01;4a] appears. Press and

hold the ß Key and change [`~no] to [`yES] by

pressing the Down Key ¯. Release the ß Key.

The current output value appears in the display.

Press the Up ¿ or Down Key ¯ to adjust the dis-

play value to match the value from the volt/amme-

ter. The unit should stabilize within one second. Re-

peat until the volt/ammeter reads 4.00 mA, ±0.1

mA. Press the Down Key ¯ to store the value and

move to the next parameter.

8. At Output 1 Calibrate 16 mA parameter [01;16],

press and hold the ß Key and change [`~no] to

[`yES] by pressing the Down Key ¯. Release the

ß Key. The current output value appears in the

display. Press the Up ¿ or Down Key ¯ to adjust

the display value to match the value from the

volt/ammeter. The unit should stabilize within one

second. Repeat until the volt/ammeter reads 16.00

mA, ±0.1 mA. Press the Down Key ¯ to store the

value and move to the next parameter or press the

Infinity Key ˆ to exit the Factory Page.

9. Rewire for operation and verify calibration.

Restoring Factory Calibration

• Press the Up ¿ and Down ¯ keys together for six

seconds until [FaCT] appears in the display.

• Press the Down Key ¯ to step through the parame-

ters until the [rESt] appears.

• Press and hold the ß Key and change [`~no] to

[`yES] by pressing the Down Key ¯. Release the

ß Key and press the Infinity Key ˆ to exit the

Factory Page.
