6.1.DMX addressing
The control panel on the front side of the base allows you to assign the DMX fixture address, which is defined as
the first channel from which the IMAGE SPOT 250 AT will respond to the controller.
If you set, for example, the address to channel 5, the IMAGE SPOT 250 AT will use the channel from 5 to 14 for
control.
Please, be sure that you don’t have any overlapping channels in order to control each IMAGE SPOT 250 AT
correctly and independently from any other fixture on the DMX data link.
If two, three or more IMAGE SPOT 250 AT are addressed similarly, they will work similarly.
For address setting, please refer to the instructions under "Addressing"(menu "
A001"
).
Controlling:
After having addressed all IMAGE SPOT 250 AT , you may now start operating these via your lighting controller.
Note:
After switching on, the IMAGE SPOT 250 AT will automatically detect whether DMX 512 data is received or
not.If there is no data received at the DMX-input, the display will start to flash
"A001"
with actually set address.
This situation can occur if:
- the 3 PIN XLR plug (cable with DMX signal from controller) is not connected with the input of the IMAGE SPOT
250 AT
- the controller is switched off or defective, the cable or connector is defective or the signal wires are swap in the
input connector.
Note:
It’s necessary to insert the XLR termination plug (with 120 Ohm) to the last fixture in the link in order to
ensure proper transmission on the DMX data link.
6.2.Remotely controllable functions
Lamp
The IMAGE SPOT 250 AT is to be operated with a MSD 250/2 GY-9,5 lamp.
A relay inside of the IMAGE SPOT 250 AT allows you to switch on and off the lamp via the control panel on the
top side of the base or via your remote control without affecting the rest of the lighting.
To switch On/Off the lamp,use the
[Power]
-button or
[Blackout/lamp Off]
-button on the remote control .You can
use also menu "
LAMP
"- please refer to "Switching On/Off the lamp ".
Note:
It is also important to note, that the discharge lamp is cold restrike types, that means, that they have to be
cold before re-striking. For this reason, you have to wait 5 minutes (max. speed of fan must be adjusted) after
having switched Off the lamp before you can switch it back On again. If you try to switch On the lamp within 5
minutes after having switched it Off, the IMAGE SPOT 250 AT will store this information and automatically ignite
the lamp when the 5 minutes period has expired. The message
"HEAt"
will appear on the control panel display of
the IMAGE SPOT 250 AT. If the ignition of the lamp is seven times unsuccessful, on the display will appear
"LA.Er"
, meaning that the lamp could be damaged or even missed, or there could be a failure on the ignitor or
ballast.
Rotating gobo-wheel
The rotating gobo-wheel includes 5 replaceable and indexable gobo posisitions.
Focus
Motorized focus enables the beam to be focused anywhere on the stage.
Dimmer/Shutter/Strobe
Smooth 0 - 100 % dimming is provided by the combined mechanical dimmer/shutter unit. This unit may also be
used for strobe effect (max. 10 flashes per second).
Fans
The IMAGE SPOT 250 AT is cooled by three axial fans - two in the projector head and one in the base. The speed
of the fans (and of course the noise) can be continuously reduced if very quiet performance is required.
By the control panel using the
"FAnS"
function you can choose 5 types of the fan speed operating modes.
7.Stand - alone mode
The fixtures on a data link are not connected to the controller but can execute pre-set programs which can be
different for every fixture.To set the program to be played,see the "Stand-alone setting"
(
menu
"St.AL."
).
