RS 5310009G1, 5810010G1) modules 5810009G1 and 5810010G1 have two adjustment procedures:one for the internal frequency loop, the other for Internal Frequency Loop Adjustment 1. Open switch U59-S1 and close U59-S2 (see figure 4-6). Checkthat U59-S3 is closed. 2. Connect one channel of the oscilloscope to TP6, the otherchannel to TPS, Trigger on TP6.

Adjust C31 (accessiblethrough the right side of the can) until the two waveforms are stable at the proper period ( ms for 60 Hz line, ms for 50 Hz line). Adjust C31 to minimize drift ofthe sawtooth waveform at TPS. See figure 4-7. 3. Now close U59-S1 and open U59-S2. While observing thesignals at TP5 and TP6, carefully adjust C31 to align thepulse at TP6 with the zero crossing of the waveform at TPS. External Synchronization Adjustment 1. Connect source signals to Jl and U3 3-S1 and U3 3-S2 as needed» high impedance). Set termination(closed =75 ohms, open 4-18. 5-U—U—U s9
