17.3 ISI Technical Specifications
This section outlines the Mark 7 Arterion specifications for the output signals and input signals for the
ISI, and shows pinouts for legacy ISI connector, universal cable, and Siemens cable.
NOTE: Systems are configured for Universal ISI operation. If configuring for Siemens sys-
tem, contact local service for assistance.
17.3.1 ISI Output Specifications
The tables below list the output signals and the relay contact outputs for the Mark 7 Arterion ISI.
Table 17 - 1: Output Signals
Signal Name Description
Extended_Arm
This signal is a pair of relay contacts output from the Injector. When active,
it indicates that the Injector is in an armed state and is ready to accept the
start input from the Imaging System. This signal operates as an Extended
Arm; it becomes active with the arming of the Injector and remains active
after an injection until the signal that initiated the injection (e.g.
INJ_START signal from the Imaging System) is deactivated.
NOTE: The Injector still disarms at the completion of the
injection; only this ISI armed signal is extended.
Injecting
This signal is a pair of relay contacts output from the Injector. It indicates
that the piston on the Injector is in motion.
X-Ray Trigger
This signal is a pair of relay contacts output from the Injector. When the
Injector X-ray delay has expired, this signal becomes active and notifies
the Imaging System to start the X-ray. Like the Extended Arm signal, the
X-RAY_TRIGGER signal remains active until the signal initiating the
injection (e.g. INJ_START signal from the Imaging System) is deactivated.
Inj_Hand_Switch_On
This signal is a pair of relay contacts output from the Injector. When the
INJ_HAND_SWITCH_DISABLE input is active and the Injector is armed,
this signal indicates when the Injector hand switch (contrast activation
only) or foot switch is in an “on” position; otherwise, this signal is inactive.
