Edwards nXLi Series User Manual

CAUTION:
This is an industrial (Class A
, Group 1) product as dened by EN55011 and EN61325. To
ensure compliance with European Electromagnec Compability (EMC) requirements
for EMC emissions, please note that it is not intended for use in domesc buildings or in
properes directly connected to an electrical supply network which also supplies
domesc buildings. "Group 1" is dened as equipment which does not use RF energy as
an intrinsic part of operaon or process.
Operaonal modes
The pump implements the f
ollowing control modes:
• Manual control mode – using buons on the user interface panel
• Parallel control mode – via the 15-way D-type logic interface connector located on
the rear of the pump
• Serial control mode – via the 15-way D-type logic interface connector located on the
rear of the pump
• Autorun
In addion to the above control modes, the pump can also be controlled via a digital
operator which is available as an accessory. It is connected to the pump via the digital
operator connector socket on the user interface panel (Figure 2 on page 12, item 10).
Manual control mode
The pump control funcons of the user interface control panel are detailed in Figure 2 on
page 12.
Start/Stop
Use the buons on the user interface control panel to start and stop the pump. The stop
command does not isolate the pump from the electrical supply.
When the pump is accelerang to its full speed the run indicator LED (Figure 2 on page 12,
it
em 1) will ash. When the pump has reached its full speed the LED will stop ashing and
stay lit. If an inlet valve is ed it will open when the pump has reached full speed.
Standby
Standby mode enables the pump to be run at a reduced speed to improve the service life of
the pump.
Press the standby buon to select the standby mode. The standby mode indicator LED
(Figure 2 on page 12, it
em 5) will illuminate. The pump will run at factory default standby
speed (89% of full speed). To return to normal run speed, press the standby buon again,
the standby mode indicator LED will switch o.
Vacuum performance will be reduced when operang at standby speed.
Parallel and serial control mode
It is possible to operate the pump remotely using the 15-way D-type connector ed on the
panel at the rear of the pump (Figure 1 on page 11, item 8).
The 15-way D-type connector is PELV-double insulated. It is recommended that galvanic
isolated relay contacts are used to avoid ground loops or spurious EMC issues.
