LiQuilaz II E and S Operations Manual
Chapter 4 Operation
Capillary Protection
Never allow the LiQuilaz II to completely dry. If it is to be disconnected from the
process line or its sampler (SLS Family), fill it with a 10
% solution of your laboratory
glassware cleaner and water. Plug up the inlet and outlet with appropriate fittings.
Status LED
A status LED on the front panel next to the liquid connections illuminates as follows
(when sensor configuration is default or
set led 1
):
Flashing green
No Ethernet connection to host computer
Green
Laser OK AND connected to host via Ethernet
Red
Laser error OR Ethernet protocol error
The status LED can be configured via a serial setup command (see “set led n” on
page
G-2). When communicating via RS-485, use “
set led 0
”. Otherwise the LED will
flash green, since there is no Ethernet host attached.
Activity LED
An activity LED (located below the status LED, see
) illuminates when a
particle is detected, providing a quick indication of whether the instrument is
sampling. The Activity LED will stay illuminated if a laser error is detected.
