The 0-7 V / 5 0 VA regulating transformer
(fig. 1 ) w i l l a c c e p t t h e 6 V / 1 0 W a n d 6 V / 2 0 W
low-voltage lamps, the circular stand for
transmitted light with 6 V/10 W halogen
bulb, the attachment for vertical and oblique
Observation and the coaxial illuminator with
6 V / 2 0 W halogen bulb. A maximum load-
ing of 50 W is to be connected to the two
sockets (66) (fig. 2).
The 0-12 V / 1 0 0 VA regulating transformer
(fig. 3) is used with the transmitted-light
stand for bright and dark field with 12 V /
100 W halogen bulb and with the coaxial
illuminator if a 12 V / 2 0 W halogen bulb is
fitted. It has three sockets which accept a
maximum combined loading of 100 W (fig. 4).
- Set the voltage selector (67) to the voltage
available:
Position 11 5 for 100-120 V
Position 220 for 200-240 V
- Connect the power cable to socket (65) and
to the power supply.
Setting the limiting voltage:
The dick stop 6 V or 1 2 V prevents over-
loading of the bulb. Turn the regulating
knob (63) clockwise until it engages.
Slacken the screw on the metal ring (64).
Turn the regulating knob back to zero.
Connect the lamp to the socket (66). Turn
the regulating knob until the Voltmeter
shows 6 V or 1 2 V, as appropriate.
Tighten the screw on the metal ring.
Changing the fuse:
Pull out the power cable.
Remove the screw (68) from the underside.
Lift off the housing.
Replace the defective fuse:
7 V: 8A, 5x20(214 477)
12 V: 2x800 mA, 5x20 mm (343 950)
