Injector Modes

Lockouts

Modules. CiA 425 Part 2 specification defines a standard way for an
injector to behave.
Classes
The CiA 425 specification defines how a scanner controls an injector. In this
definition they specify 6 "classes" or levels of control. Each higher number
offers more features and includes all features of the previous classes. The
actual class for a pairing is derived from the class of the least capable
component in a pair.
• Class 0 - scanner can monitor the "state" of the injector
• Class 1 - triggering interface (each device can request the initiation of
the other)
• Class 2 - injector can provide injection summary data to the scanner
• Class 3 - scanner can read injection protocol configuration from
injector
• Class 4 - scanner can write injection protocol to injector
• Class 5 - scanner can control flow rate of injection in real time
The ISI 800 Module currently conforms to Class 1.
There are 3 available ISI Modes; which are determined by the scanner:
• Monitor Mode - The scanner can monitor but not influence the
injector.
• Tracking Mode - The injector cannot start an injection when the
scanner is not ready.
• Control Mode - Either the Scanner or the Injector can request the
initiation of a procedure.
The scanner can lockout the following injector operations:
• Arm Lockout - the injector will not allow local arming (at the injector).
• Start Lockout - the injector will not allow local starting.
• Resume Lockout - the injector will not allow local resume if the
injector is in a hold condition.
• 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).
