6.4 Power On/Off Control
The power switch on the pump is the main switch for power on/off
control. The main power switch is turned on during initial installation of
the pump.
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.
Whenever the power to the pump is turned on, the following sequence
of events occurs:
•
The pump performs a self-test.
If the self-test is not successful, the status indicators are red and the
pump is not ready for analysis. Check the Chromeleon Audit Trail for
the related message and take appropriate remedial action.
• The pump starts operation with a seal wash cycle. Before turning on
the pump, check the liquid level in the seal wash reservoir. Consider
checking also the liquid level in the waste container.
