Reduction of the modelling light: Setting ex work: "off” (--)
The activation of this function is recommended on power mains
with great fluctuations. The voltage for the modelling lamp is
reduced (light output ./. 1/3 f-stop), which results in a longer
service life of the halogen lamp. If this function is activated, the
digital display shows the value "on”.
12. Protective facilities / Fault indication
12.1 Cooling
fan
The cooling of flash tube, modelling lamp and internal electronics is effected by a cooling
fan. It also runs when the modelling light is turned off. The cooling works on two levels,
the fan runs smoothly when small flash sequences are effected. With longer flash
sequences, the cooling fan switches to the higher level.
12.2 Display
"th"
If excessively high temperatures build up inside despite the fan cooling, the charge mode
will be blocked and a long audible signal will be generated. The modelling light is blocked
as well for about 6 minutes. The digital display shows the indication "th” during the
cooling period. The cooling process is accelerated by the fan which is still in operation.
Attention: Do not switch off the unit during the cooling period!
If the unit is switched
off too early, only a small number of flashes can be effected until the next
blockout, when switching on again the unit, despite a long break, because
the processor could not completely pursue the cooling process.
12.3 Display
"A1"
The unit is equipped with an automatic afterglow blockout. If the flash tube exhibits (e.g.
at the end of its service life) afterglow, this blockout will block further charging to prevent
consequential damage. This status is also discernible by the ready display, which is no
longer green. The blockout can be cancelled by switching the unit off and on again.
12.4 Display
"A2"
This indication is shown, when the unit is overcharging. Switch off the unit and switch it
on again after a few minutes. If this fault continues to exist, please contact an after-sales
service centre
