6.4 Power On/Off Control
The power switch on the detector is the main switch for power on/off
control. The main power switch is turned on during initial installation of
the detector.
For easier handling, you can use the power button on the front left of
the Vanquish system base (system power button) for power on/off.
Observe the following:
• All
modules in the Vanquish system that are connected to the
system base via system interlink cables are turned on or off
simultaneously when the system power button is pressed.
•
When the power is on, the system power button is pressed in. When
the power is off, the system power button stands out.
•
If the main power switch on a device is off, you cannot turn on the
device with the system power button.
•
To turn off a device completely, you
have to
turn it off with the main
power switch on the device. Pressing the system power button will
not be sufficient to turn off the power to the device completely.
Upon power up, the detector performs a self-test. If the self-test is not
successful, the status indicators are red and the detector is not ready for
analysis. Check the Chromeleon Audit Trail for the related message and
take appropriate remedial action.
After the self-test, a warm-up phase follows. During this phase, the
detector monitors the temperature of the internal components. If the
ambient temperature is cool or cold, the warm-up phase can take
longer.
