Lighthouse REMOTE Liquid Particle Counter (4-20mA output) Operating Manual

Communication Ports
WARNING:
When
daisy chaining multiple
instruments, connect IN
ports only to OUT ports.
DO NOT connect an IN
port to another IN port.
Doing so will damage the
sensor and void the
warranty.
The RJ45 port incorporates Serial communications to allow short
distance point-to-point RS232; the 4-20mA connector provides
standard 4-20mA communications.
The RS232 protocol is provided for quick simple cable connections to a
standard PC COM port and is used for single-unit communications
only. Please contact a Lighthouse Sales Representative for the LWS
RS232 converter kit.
For more information, please see “Programming” on page 4-1 .
DIP Switches
The DIP switches set the address of the instrument for RS232
configurations and the communications mode. See “Maintenance” on
page A-1 for details.
Positions 1-6 set the address of the instrument.
Position 7 and 8 set the communications mode.
To change the switch positions requires a small Phillips screwdriver to
remove the cover plate and a small pointed tool, such as a paper clip.
Power
This REMOTE instrument uses an external 24VDC power supply. The
power input is 100-240 VAC, 50-60Hz, 0.4A and output is
24VDC,
0.62A.
External Alarm Output
The External Alarm Output is a 2-wire, normally-open dry contact
relay rated at 0-60V AC/DC, 1A.
The 9-position screw terminal block can be removed from the
instrument by unscrewing the holding screws on either side of the
connector block.
The external alarm is triggered when the alarm-enabled channel’s
particle count exceeds the configured threshold. The alarm will stay
active until the beginning of the next sample which resets it to Off.
