17.3.2 ISI Input Specifications
The Mark 7 Arterion ISI is activated by a contact closure at the imaging system, and it is powered by
internal 24VDC isolated supply with short circuit protection at the Mark 7 Arterion Injector.
The tables below list the output signals and the Opto-isolated Input requirements.
17.3.3 ISI Connector Specifications
The figures below show the pinouts for the Legacy ISI connector, ISI Universal cable, and ISI Siemens
cable. Table 17 - 5 on page 17 - 133 provides a brief description of each pin in the Legacy ISI
Connector.
Table 17 - 3: ISI Input Signals
Signal Name Description
Inj_Start
This signal is an input to the Injector and is generated by the Imaging
System. Once the Injector is armed and the EXTENDED_ARM signal is
active, activating this signal enables the Injector to start. Deactivating
this signal during an injection will abort any injection in progress and
disarm the Injector.
Inj_Disarm
This signal is an input to the Injector and is generated by the Imaging
System. This signal must be inactive to allow the Injector to be armed.
When the Injector is armed or is injecting, activating this signal will disarm
the Injector and abort any injection in progress.
Inj_Hand_Switch_-
Disable
This signal is an input to the Injector and is generated by the Imaging
System. This signal must be inactive to allow the Injector hand switch and
foot switch to function normally when in ISI mode. When this signal is
active, the Injector hand switch (contrast activation only) and foot switch
are disabled from directly starting the Injector and the Injector can only be
started from a remote INJ_START control.
