During calibration ASR003 makes use of manual control pushbuttons and some relays
as described in the following table:
The procedure must be as follows:
1. Switch on collimator and wait for the correct setting of initial procedure and axes
reset of all boards. Collimator will automatically achieve pre-defined format and will
be ready to accept all external signals.
2. Insert the jumper between 2 and 4 pin of J3 programming connector of ASR003
control board. At this point all operations on the board will be inhibited and it will be
possible to start the calibration procedure.
3. Correct insertion of jumper will be signalled by blinking led of the relay every sec-
ond that controls MANUAL output.
4. At this point the system indicates the first calibration phase by activating output 1
and deactivating inputs 2 and 3.
5. Bring FFD to 78 cm and activate input 2 of the board (M39 IRIS CLOSE). When
input pushbutton is released the average measurement of the signal coming from
FFD potentiometer will be achieved on the system. Subsequently the signal will be
compered to absolute minimum value in order to evaluate the measurement taken
and saved.
6. At this point the system will deactive output 1 and active input 2 in order to show
that it is ready to obtain the second measurement. Bring FFD to 100 cm and repeat
action by activating input 2 (M39 IRIS CLOSE).
Attention:
Calibration will not initiate if configuration is not correct.
Element
Function description
Input
Iris close pushbutton
(terminal M2)
The board performs the measurent, saves the results for
table and/or stand position.
Iris open pushbut-
ton(terminal M1)
Allows to return to previous calibration step and repeat
the process if necessary.
Output
MANUAL relay
Intermittent operation over 1 s periods to indicate that the
board is on standby for the operator (depending on the
calibration step).
ERROR relay
Activated if an error is detected. In case of an error the
board sets to the point where the error occurred. Exam-
ple: if at step 2 the table is lowered instead of being
raised, an error is signalled and the board requires the
correct table position instead of going to step 3).
