22 Roboscan Pro 1220 - operator’s manual
ErrA
The 'A-Module Error' indicates that there is no communication between the serial data receiver
module and the A-Section electronics-module.
Errb (Pro 1220 CMYR only)
The 'B-Module Error' indicates that there is no communication between the serial data receiver
module and the B-Section electronics-module.
ShEr
'Short Error' appears if the Pro 1220 "detects" that the lamp is on but no 'Lamp On' command has
been sent. This can occur if the lamp relay has stuck in the on position or the lamp-power feedback
circuit has failed.
The following information messages may appear on the display:
Hot
This message appears if you attempt re-strike the lamp within 8 minutes after having switched it
off. The Pro 1220 will then store the 'Lamp Power On' instruction and ignite the lamp when the 8
minute period has expired.
Auto / address and PASS
After having switched on the Pro 1220 it will default into protocol auto-detection mode which is
indicated on the display which will switch between 'Auto' and the channel number on the previ-
ously used fixture address. The message 'PASS' will appear for about half a second when the proto-
col type (Martin or DMX) has been detected and communication between the electronics-modules
verified.
