Job Card CARE A001 - Detector protection during system shut-
down
1 HOSPITAL/SYSTEM SHUTDOWN
• The Digital Detector used in the Senographe system contains components which are extremely sen-
sitive to variations of temperature and humidity.
Any large or long term variation in temperature or humidity may cause permanent damage to the
detector.
In normal operation, including normal shut-down, the detector is protected from damage by the Con-
ditioner, which controls the temperature and internal humidity of the detector within close limits.
• If the system must be completely shut down for any reason, for example if the hospital depart-
ment is closed for a vacation period, special precautions must be taken to avoid damage to
the detector.
2 DETECTOR PROTECTION DURING SHUTDOWN
There are two possible methods of protecting the detector if the normal system power must be switched
off during a prolonged shutdown:
• Connect the Conditioner to a normal power outlet and leave it switched on. This ensures
that power is returned after any brief power outages (due to storms, etc.). If the Generator system
is left on standby, it does not start up automatically after a power outage, and power is switched
off permanently
• Disconnect and drain the cooling circuit as much as possible. Ensure that no coolant is left
in the Detector or in the Conditioner. Use a syringe or similar tool if necessary.
! Notice:
When the Detector is not protected by connection to a functional Conditioner, the following
storage conditions must be respected:
Humidity: 10% min., 50% max. (up to 95% R.H. can be tolerated for less than two weeks).
Temperature: +10°C (50°F) min. to +25°C (77°F)max.
(-10°C (14°F) min. to +50°C (122°F) max. for less than one day).
Atmospheric pressure: 500 hPa min., 1060 hPa max.
