BOARD
ASR003 board is the central control unit for collimator R 605DASM.
Configuration
This board features ample configuration possibilities. To access configuration, connect
to serial gate J2 via CAN communication protocol.
FFD
CONFIGURATION
Stepless single: FFD value is obtained locally by readings of board analogic inputs. It
may also be received in millimetres directly via CAN-Bus. The collimator continuously
tracks FFD value for reproduces a format of constant dimensions on the receiver/plate.
FFD Measuring Source:
The value of a stepless FFD may be determined locally, readings of ASR003 inputs, or
received via CAN-Bus in digital format from external equipment.
Focus Distance:
All the calculations performed by the collimator require an 80mm F-D (Focus Dis-
tance). If the mounting distance of the collimator is not 80mm, the correct value may
be specified.The parameter may also be used to correct small defects in the measure-
ment of projected formats.
Hystereris on FFD change
This is a small millimetric variation to the FFD which triggers format correction when
it is detected by the analogic inputs of ASR003.
FFD Observation time
Through the analogic inputs, measured FFD is tracked until each variation becomes
smaller than the hysteresis and the time limit has expired. The collimator starts to re-
track FFD variation only when the variation exceeds the hysteresis window.

ORMAT
CONFIGURATION
Format programmes:
8 format programmes are available. Each programme includes limit values for the open
of Iris, Long, Cross filtering shutters and a rotation angle for the filtering shutters. Once
a format is selected, the collimator positions the iris, long and cross and filtering shut-
ters as indicated by the programme: It will now be possible to close the field but not
open it further.
