2 - Operation
With the ISI 800 Module installed, the injection system can function
independently or coupled to the scanner. Depending upon what mode of
operation the scanner is in, this link can allow the scanner to automatically
request the initiation of an injection, or permit the injector to automatically
request the initiation of a scanning procedure.
NOTE: The scanner CANNOT override any injector operation that is
considered safety critical; for example, check for air, hold
during an injection or stopping an injection.
NOTE: The scanner manufacturer and/or user must make the final
determination of the mode of operation for the coupled
injector and scanner. The scanner manufacturer is
responsible for providing operation instructions for their
system.
The ISI 800 Module gives the scanner the ability to lockout the following
injector local operations:
• Arm - the injector can not be armed at the injector
• Start - the injector can not be started by the injector's controls
• Resume - the injector will not resume the injection if Hold button is
pressed during the injection.
• Protocol Configuration - the injector protocol configuration cannot be
changed. (Protocol Config Lockout does not affect the ability to use
the Setup screen).
NOTE: This last bullet applies only to the Display and Control Unit
(DCU).

For the Certegra Workstation, some behaviors of the injector head arm
indicator lights (the blue and green indicator lights around the manual fluid
movement knobs) have been modified.
In independent and monitored operation, where the injector cannot request
the scanner to start, the arm lights on the injector head flash once per second
when the injector is armed.
In coupled operation with the scanner where the injector may request the
scanner to start (the injector will be labeled as described in the symbols
section), the arm lights flash approximately twice per second with a "short
flash, long flash" pattern.
The following instructions apply when the system is in Monitor Mode.
NOTE: When in Monitor Mode, the injector operates independently.
Communication must be established between the injector
and the scanner in order for monitoring to take place. The
scanner icon will not show when the system is in Monitor
Mode.
