Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.
Overall- value for money- I recommend

Excellent quality and quickly delivered manuals at a fair price. Great care is taken in the reproduction process. Even photographs and highly detailed drawings are as clear as in the original. That cannot be said for some freelance manual copies I have obtained from the web. If you have exhausted your internet search of technical manuals, try Owner-Manuals.com. If they do not have it, I do not think it exists. Perhaps, if requested, they may be able to find it. Their resources are certainly greater than most. Shopping here certainly beats waiting for months or years for the manual you seek to appear in an internet auction or garage sale.

the Manual was made available as promised, the scans were excellent..Good Work !!!

It's complete and helpful manual with good quality of scan. Thanks very much.
Adjustment
3-3-2 Adjustment after assembling (PDP Module adjustment) (1) Setting up the initial voltage and adjusting the voltage wave form of Vsetup (2) Measuring the voltage Margin of Vs and deciding the voltage (3) Adjusting and checking the voltage of DC/DC pack (Vsetup, Vscw, -Ve, -Vy) (4) Adjusting the voltage wave form of Vset-down (5) Measuring the voltage Margin of Vset-up and deciding the voltage (6) Adjusting the wave form of final voltage 3-4. Adjusting the Board Group (Applying the Jig Set) 3-4-1. Using Tools (1) Digital oscilloscope : More than 200MHz (2) DVM(Digital Multimeter) : Fluke 87 or similar one (3) Signal generator : VG-825 or similar one (4) DC power supply - DC power supply for Vs (1) : Should be changeable more than 0-200V/ more than 10A - DC power supply for Va (1) : Should be changeable more than 0-100V/ more than 5A - DC power supply for 5V (1) :Should be changeable more than 0-10V/ more than 10A - DC-DC Convertor Jig (1) : The Jig which has voltage equivalent output of PDP42V5#### Module after taking the Vs, Va, 5V voltage. - Voltage stability of power supply : Within 1% for Vs/Va, within 3% for 5V 3-4-2. Connection diagram of measuring instrument and setting up the initial voltage (1) onnection diagram of measuring instrument Refer to Fig. 8.(Connection diagram of measuring instrument that adjusting the voltage wave form) (2) Setting up the initial voltage Initially setting up voltage : Vcc:5V, Va:65V, Vs:190V But, Initially setting up voltage can be changed by the set up range according to the Module s characteristic. 3-4-3. How to Adjust (1) Adjusting the Voltage Wave form of Vsetup - Connect measuring instrument like the connection diagram Fig. 8. - Turn on the power of the measuring instrument like the <Caution> item Fig. 8. - Connect the oscilloscope probe to P4 connector (80 Pin) of Y-SUS PCB and GND. - Turn the VR1 of Y-SUS PCB and make the A wave form Fig. 9 to be 25 5 s. (2) Adjusting Vset-down Voltage Wave form Turn the VR2 of Y-SUS PCB and make the B wave form Fig. 9 to be 190 5 s. (3) Adjusting Vramp Voltage Wave form - Connect oscilloscope Probe to the B37(Pin) of Z PCB and the GND of PCB - Turn the VR3 of Z PCB and make the C wave form Fig. 10 to be 15 2 s. But, in case of not setting up the Test point, produce same output and adjust wave form connect to other pattern or parts which has no possibility of short.
