16 -FROST –CH 16-
Adjustable from channel 16, the linear regulation of the frost concurs.
17-MSPEED –CH 17-
Mspeed controls PAN and TILT and is intended as the time required to complete a movement from one position to
another. This means that fixtures with the same Mspeed value will reach their destination at exactly the same moment.
It's therefore possible to set movement times for each fixture which are independent from the times sent by the lighting
console.
DMX values between 000-003 allow the lighting console to control the movement, whereas from DMX value 004 it's pos-
sible to allocate the movements a movement time.
To determine Mspeed time, refer to the conversion table.
18-REMOTE LAMP IGNITION AND RESET– Ch 18 –
The lamp can be switched on (and off)can be controlled via DMX by means of a lighting console. In fact, after the Giotto
has been powered up, the lamp will remain off until the “lamp ignition” command is sent.
This function has no effect if it's not enabled by means of the fixture's built-in microcomputer. In this case, the lamp will
ignite automatically without waiting to receive the command from the lighting console.
In the event of the lamp being switched off accidentally, it's advisable to wait at least 5 minutes before sending the igni-
tion command. Nevertheless, if the command is sent earlier, Giotto Spot carry out lamp ignition, automatically carrying out
restrike attempts at regular intervals of 3 minutes.
Lastly, Giotto Spot 1200 has another function which automatically reduces the power of the lamp by 50% every time the
shutter or dimmer are closed. This function ensures considerable improvement in fixture cooling and increases lamp life.
The lamp obviously immediately returns to full power as soon as the shutter or dimmer is opened again.
Should any problems arise, a reset command can be sent to the fixture so that all the motors return to the starting posi-
tion before beginning to carry out the commands received from the lighting console.
