Turning off¶
Note
Before switching off the stand, move the unit into the parking position, as this cannot be done when the system is powered off due to the motorized C-arm.
Turning off – recharge configuration¶
If the shutdown button is pressed while an exam is open, the system will notify that the exam must be closed before turning off the system.
Once the unit is turned off, deactivate the main power switch:
Then, disconnect the power plug.
If the wireless monitor trolley is present, it can be turned off completely independently of the c-arm stand by switching off the green power switch located on the rear panel.
Emergency switch off¶
Emergency power off occurs by pressing one of the emergency buttons available on the machine.
In the RECHARGE configuration, there is only one emergency button, located on the horizontal trolley of the stand.
Optionally, and for both configurations, there may be an additional emergency button located on the side of the MINITROLLEY ETS15 trolley.
Finally, optionally, and for both configurations, there may be an emergency button located on the ROOM IN USE interface installed on the wall of the room.
Pressing one of the emergency buttons immediately cuts off the power to the system, meaning that the movement and X-ray emission functions are disabled and turned off.
The emergency shutdown buttons are of the manual reset type. When pressed, they stay in the engaged position until the operator manually resets them to the rest position by rotating them clockwise and releasing them.
Before reactivating an emergency button, it is important to ensure that the issue which caused the emergency stop has been resolved.
After reactivating the emergency button, it is advisable to perform a complete system restart.
Warning
The emergency button located on the ETS15 trolley (mini trolley) is only operational when the trolley is connected to the main cart.
Warning
The emergency button located on the ROOM IN USE interface is only operational if the unit in use is connected to it.
Emergency restart¶
The unit, due to its characteristics and its normal use, does not provide any emergency operation status, meant as a working condition with limited functions. In case of accidental switch off, or temporary blackout that causes a unit switch off, the user will need to normally turn the whole system on.
Warning
In case an interruption is suspected due to a malfunction, the following restoration procedure must be carried out with the utmost caution.
Follow the flow chart below to restart the unit after an emergency shutdown.
Warning
In case of a suspected possible fault, the restart must be immediately stopped and the unit must be disconnected from the mains.
Note
In the event that the shutdown should occur by means of the emergency button, reactivation takes 30 seconds.
X-ray emission interlock key¶
The unit is equipped with a physical interlock system for the emission, consisting of a key switch, in addition to the software interlock that is active (emission inhibited) until a new exam is opened.
The key for the interlock emission switch is located on the left side of the stand.
X-ray door interlock¶
Optionally, the unit can be equipped with an interlock function that activates when the door of the room where the unit is used is opened.
This function requires the ROOM IN USE interface and has the same effect as the key interlock switch located on the unit, as described in the previous paragraph.
