[Tig] Ursa

Thu Aug 9 04:57:53 PDT 2007

 At DR we modified the mk3 so they were like the Ursa, i.e. at crt heater-on there should go 30 seconds before eht could be turned on. Then we made a timer so if the tk had no running servo for 90 minuttes the eht and the heater was switched off. 
PEC's was never swithed off. They tend to be better with age, and burn out *very* slowly. 
Mk3 was left nightover with power on because of poor stabillity in analog circuits. 

The Ursa was left with power on in the believe that it was better to keep a constant temperature in the tk to minimize faults. Both EHT and heater was switched off.

 Hello, you're telling the EHT and the CRT should
always keeping ON position during at the night times,
even there is no any work on telecine suit?

 One of my client RKV Studioss, Chennai-INDIA., have
URSA GOLD with Davinci DUI., they're switching OFF the
telecine while leaving night time and turning ON the
total systems next day morning.

Till date ( this telecine suit started last year (
2006) same august month) no any problems happened on
that telecine suit.

Another one client DVIS, Chennai - INDIA., switching
OFF the CRT while there is no any work at night time.

Finally., IF YOU HAVE ANY DOUBT WITH URSA MACHINES
PLEASE CONTACT CINTEL., THEY WILL GIVE MORE
INFORMATIONS.

see you...
