Philips Optimus - 15.2 Tube Conditioning; 15.2.1 General Information

Optimus 80kW with 141kV, UCOMP = +1V AV HT with overshoot
mean value of UCOMP
kV actual value
kV actual value + UCOMP
(Fig. 30)
b) 125kV setting (50/65/80kW)
▪ Read the mean value of U
COMP
for 125kV (in principle figure 29 or 30).
▪ Correct the factor duty cycle till
U
COMP
meets the required reference of 0V.

125kV 200mA PCB kV_control 4: +0V ±0.5V 125kV
Table 2: Factor duty cycle, 125kV limit
Example how to correct the factor duty cycle:
PCB kV_control 3:
▪ If the mean value of UCOMP is: > +1V increase the factor duty cycle in steps of 0.01
< -0.5V decrease the factor duty cycle in steps of 0.01
PCB kV_control 4:
▪ If the mean value of UCOMP is: > +0.5V increase the factor duty cycle in steps of 0.01
< -0.5V decrease the factor duty cycle in steps of 0.01
▪ Check also the kV peak value AV HT (not the overshoot), it must be 125kV for 125kV setpoint.
▪ Remove short link EZ130 X23 GAIN_IN.
▪ Record the results in table 2.
