4-20mA1+ to 4-20mA10+: Analog output positive terminals for peak #1 to peak #10
(use 500ohm resistor between + and – terminals for 0-10VDC resolution on data recorder)
4-20mA1- to 4-20mA 10-: Analog output negative terminals for peak #1 to peak #10
(use 500ohm resistor between + and – terminals for 0-10VDC resolution on data recorder)
Range 1 to Range 10: These dry contacts can be N.O or N.C selectable in chromatogram menu.
These relays are used to indicate on which range is the instrument. One relay is used for each peak.
(Example : Peak 1 : Contact relay is between Range 1 and COM terminals)
COM: The COM is shared with Ranges, Status, Alarm1 and Alarm 2 terminals
STATUS: This dry contact is open when an alarm is active (The contact status is user's
configurable)
Aux. : This dry contact is a spare contact (Used for options only)
ALARM1: This dry contact is open when process value is higher than the alarm1 set value
ALARM2: This dry contact is open when process value is higher than the alarm2 set value
ChromOut+: High resolution voltage Chromatogram output+ terminal (output voltage is 0-5VDC
between ChromOut+ and ChromOut- terminals)
ChromOut-: High resolution voltage Chromatogram output GND terminal
GND : This is a common GND (Used as GND contact for options and Streams only)
Stream 1 to Stream 8: These dry contacts are closed when the associated stream has been selected.
These contacts are used to remotely control the LDGSS stream selector system.
(Example : Stream 1 : Contact relay is between Stream 1 and GND terminals)
Spare: spare relay for options
AUX RTD+: RTD+ contact (used for auxiliary oven only)
AUX RTD-: RTD- contact (used for auxiliary oven only)
AUX Heater+: Heater+ contact (used for auxiliary oven only)
AUX Heater-: Heater- contact (used for auxiliary oven only)
