3.7.5 Measuring voltages at rectifiers V1 to V8
The following diagram shows the position of rectifiers V1 to V8 and their terminal assignments. 3
To take measurements on rectifiers V1 and V7, you must first remove the perspex safety panel.3
RISK OF DEATH BY ELECTRIC SHOCK 3
Æ Switch the placement system off at the main switch.
Æ Disconnect the placement system from the power supply.
Æ Wait approximately 1 minute until the residual voltages have dropped to a safe level (electro-
lytic capacitor C1).
Æ Loosen the two M5 fillister head screws on rectifiers V1 and V7.
Æ Remove the perspex safety panel.
Æ Switch the placement system on and start it up.
Æ Measure the voltages.

PLEASE NOTE: The placement system must have started, otherwise there will be no AC volt-
age (3 x 140 VAC) at rectifier V1. V1 uses the 3 x 140 VAC to generate the 200 VDC supply volt-
age for the servo amplifiers of the gantry axes and 100 VDC for the servo amplifiers of the star
axes. These 100 VDC and 4 VDC supplies are fed to the AC voltage inputs of rectifier V2. Rectifier
V2 serves to "OR" the 4 VDC and 100 VDC supplies. If the placement system has not started, only
4 VDC will be present at the positive pole of rectifier V2. 3
