1.7.2 Testing the Output (cont.)
IMPORTANT: The procedure for testing all the outputs is the same. However, when testing another output, be sure to
reconnect the pulse counter at terminal block J2 . See Figure 4 on page 12 for the correct pins.
4. Use the arrow keys to enter a value for the minimum pulse on time (between 1  sec and 10,000  sec) for the
frequency of the totalizer pulses and press
[Enter]
.
Note: A complete pulse consists of equal amounts of
ON
and
OFF
times. Choose a value that is compatible with
the pulse counter to be used.
5. Use the arrow keys to enter a value for the number of measurement units represented by each pulse (between 1
and 10,000) and press
[Enter]
. That number of pulses will then be output at the specified frequency.
6. Verify that the pulse counter reads the correct value.
1.7.2.1 Procedure Options
This completes testing of the Slot 1 totalizer outputs. Do one of the following:
• To test another of the available totalizer outputs, return to Step 3 in Testing the Output above. If any of the
totalizer 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.
