4.1 Normal Start Up
Start up sequence
When AC power is turned on (using the orange
toggle switch on the electronics cage), it seems that
nothing happens for a few seconds. The electronics
module is starting up and initializing itself.
Next, the alpha numeric display on the left front of
the unit will display the message
STARTING
. If the unit
has not been turned on for a while and the optical
engine is cool, the message will say
SEARCHING FOR
SIGNAL
and the lamp will start if
AUTO LAMP ON
has
been checked in the lamp settings menu. If not press-
ing the
ON
button on the remote control or sending
an on command via RS232 will start the lamp.
If the lamp has recently been turned off, and the
optical engine is still hot, the message will read
COOL
-
ING DOWN
and a 45 second countdown will com-
mence. At the end of the 45 seconds the lamp will
turn on and the lamp fans will start if
AUTO LAMP
is
on. It shortens lamp life to turn it on when it is hot,
so the fans run for a minute or so to be sure it is cool.
If you have turned off the lamp using the remote
control the TD61 will start a 45 second cool down.
During this time, you cannot turn the lamp on. At
the end of the cool-down period the alpha numeric
display will say
READY
and you can now light the lamp
using the remote control
ON
button.
The TD61 will then lock on to the last selected
source. To search for another source press the source
button on the remote control.
After this cooling down period, you can turn on
the lamp.
Shut down sequence
When you turn off the lamp, the fan will continues
to run for a few minutes to cool the
L
amp.
CAUTION
It is bad practice to turn off the TD61 by turn-
ing off the AC power. The lamp does not cool
properly. This may shorten lamp life.
