it with a new one. Make sure that the tube is
firmly seated all the way down in the base,
the triggering contact (21) surrounding the
tube on either side.
13. Fuses
To change fuses, switch the unit off and pull
the power plug. Fuse drawer (9): Push the fuse
drawer (9) out towards the front with the aid
of small screwdriver placed behind the upper
part of the drawer. The fuse is located at the
rear, a spare fuse at the front of the drawer.
Always replace the blown fuse by one of iden-
tical rating:
Profilux - 200/400/600 220 - 240 V = T 3.15 A
Profilux - 200/400/600 110 - 130 V = T 4 A
14. Thermal protection
The units have a thermal circuit breaker that
responds to very high ambient temperature
and heavy-duty use.
When the circuit breaker acts, the flash will
not fire any more, and the modeling light goes
out. The LED (15) above the open-flash button
(14) is OFF, while all other LEDs stay lit. Once
it has cooled down sufficiently, the unit swit-
ches on automatically. Under normal operating
conditions, the built-in fan provides sufficient
cooling.
15. Pyrex globe
Profilux units for 110 - 130 V are factory-
equipped with a protective Pyrex globe (25).
To remove the globe, press the two wire springs
(26) inwards with a pointed object so that they
clear the screws (27), and lift them out. After
changing the flash tube, replace the globe (25)
and press the two springs (26) back underneath
the screws.
16. Care and maintenance
At the end of the shoot, pull the power plug.
Units that are used regularly should be serviced
by Multiblitz once a year.
The flash unit should be carefully protected
from water splashes.
