4 TouchRAD Panel
4.1 System Key-Switch
4.1.1 Overview
The System Key-Switch puts the X-RAD Biological Irradiator in one of three modes: Off, Standby
and On.
4.1.2 OFF
When the System is in the OFF state, X-Rays cannot be produced and the TouchRAD User Interface
is inoperable. When the System is initially turned to the OFF state from the STANDBY state, the
TouchRAD User Interface will take about 30 seconds to shut down.
Note-Once System is in OFF state, it must remain OFF for at least 30 seconds to ensure the
computer will start normally when System goes to STANDBY state.
4.1.3 STANDBY
When the system is in STANDBY mode, the TouchRAD User Interface is operable but X-Rays cannot
be produced. In order to produce X-Rays, the system must be put in ON mode.
Note-If user tries to produce X-Rays, a “Safety Circuit Error” will be displayed to the User
Interface.
4.1.4 ON
When the System is in the ON state, the whole system is operable and X-Rays can be produced.
By switching the System Key Switch to the ON position, the safety circuit for the X-Ray system is
closed allowing X-Rays to be produced.
4.2 Warning Lamp
The Warning Lamp is a steady yellow light that is on while X-Rays are being produced.
Note-The TouchRAD warning lamp is not included in the safety circuit as it is a secondary indicator.
If the TouchRAD warning lamp bulb fails, X-Rays CAN be produced.
4.3 Emergency Stop
The Emergency Stop is hardwired into the X-Ray Power Supply via the safety circuit and will instantly
stop X-Rays when activated. To activate the Emergency Stop, simply push the button inward toward
the panel. To deactivate the Emergency Stop, twist the button counterclockwise and it will pop out to
its inactivated state.
