1.8 Testing the Frequency Outputs

Frequency outputs may be added to the Model XGM868i by installing an appropriate option card in 

Slot 1

. This option 

card contains two or four frequency outputs, which are designated A, B, C and D.

1.8.1 Preparing for Testing

Prepare for the testing procedure by connecting a frequency counter to the desired output on the option card. See 
Figure 2 on page 8 for frequency output wiring, and Figure 4 on page 12 to identify the 

OUT(+)

 and 

RTN(-)

 pins for the 

desired output on terminal block J2.

1.8.2 Testing the Output

1.

From the 

Keypad Program

, press the right arrow key to scroll to the 

CALIB

 menu. Press 

[Enter].

 

2.

In the 

Cal 

window, scroll to 

Slot 1

. Press 

[Enter].

Note:

The 

Slot 1

 option only appears at the above prompt if an option card is installed in this slot.

3.

Scroll to the desired 

Output.

 (

Output A 

will be used as an example in this manual.) Press 

[Enter].

IMPORTANT:

The procedure for testing all the outputs is the same. However, when testing another output, be sure to 
reconnect the frequency counter at terminal block 

J2

. See

 

Figure 4 on page 12

 

for the correct pins.

4.

Enter a frequency (between 1 and 10,000 Hz) and press 

[Enter]

.

5.

Verify that the frequency counter reads the correct value.

Procedure Options

This completes testing of the 

Slot 1

 frequency outputs. Do one of the following:

To test another of the available frequency outputs, return to Step 3 in 

Testing the Output

 above. If any of the 

frequency outputs fails the test, contact the factory for assistance.

To calibrate/test additional inputs/outputs, proceed to the appropriate section.

To leave the 

Keypad Program

, press 

[Escape]

 twice.
