16. Apply a 60Hz, 33% duty cycle signal to the OP1 fiber optic input.
17. Verify that the diagnostics transmitter LED, OT1, is on.
18. Verify that the signals at TP9 and TP8 are as shown in Figure 260 .
19. Verify that the signal between TP1 and TP2 is as shown in Figure 261 and
Figure 262 .
20. Remove the jumper between TB3-1 and TB3-2.
21. Apply a constant fiber optic signal to the OP1 input.
22. Apply a 60 Hz, 33% duty cycle signal, at a 0 to +2V level, between the
TB1-2 input and COM. Verify the signals in
Figure 263 and Figure 264 .
Note that in Figure 264 there should be a 220 μS, ±20 μS time between the
rising edge of the U4-pin7 pulse and the falling edge of the TP7 signal.
