Connection and operating information
What's new
Thanks to the microprocessor control some safety functions, related to the power sup-
ply and the lamp connected to it, have been improved.
The max. power is one of the parameters that now can be set. During the operation,
the power supply checks that the delivered power does not exceed the preset value.
When exceeding, it reduces the delivered current down to a power (voltage by cur-
rent) equal or lower that the preset limit.
If the preset power value is referred to the lamp in use, an automatic control of the
max. power applied to the lamp will be obtained. The default value (3400W) aims at
protecting the power supply.
The synoptic panel allows to set/change the different operation modes (factory set-
ting: manual mode).
The possibility to set different operating modes permits an optimum use of the power
supply avoiding incorrect use.
The operation modes are exclusive i.e. when a mode has been entered, the others will
be automatically ignored (i.e. if the RS232 mode has been entered, then possible
commands from synoptic panel or from 0-10V analogue input will be automatically
ignored).
The operation modes are: manual from synoptic panel, manual from remote control,
through serial line and through 0-10V analogue input.
Two hour meters (total and partial lamp operating hours) are located on the synoptic
panel. The first one (total operating hours) cannot be reset.
A remote contact (J4, pins 11-12) activates the stand-by mode. Under this mode the
delivered current corresponds to the value set in "input parameters". This mode is
useful during the projection timeout if the lamp must stay on. This contact can be
activated under any operation mode.
