2.1.3.1 Remote sensor module input

All connections to the Remote Sensor Module (RSM) are made by connecting the supplied interface

cable between the analyzer and the RSM. Plug the cable connectors into the mating receptacles on the

analyzer chassis and RSM.

2.1.3.2 Alarm-1 relay output

Connections from the Alarm-1 relay contacts to the user’s process control equipment are made at

terminal block TB2 on the rear of the analyzer chassis (see Figure 10). The oxygen alarm relay contacts

are voltage-free Form C relay contacts, SPDT, 5A @ 250 VAC, 5A @ 30 VDC. Connect the terminal pins

in accordance with the schematic shown on the terminal ID label on the top of the analyzer chassis.

2.1.3.3 Alarm-2 relay output

Connections from the Alarm-2 relay contacts to the user’s process control equipment are made at

terminal block TB2 on the rear of the analyzer chassis. The oxygen alarm relay contacts are voltage-free

Form C relay contacts, SPDT, 5A @ 250 VAC, 5A @ 30 VDC. Connect the terminal pins in accordance

with the schematic shown on the terminal ID label on the top of the analyzer chassis.

2.1.3.4 Fault relay output

Connections from the Fault relay contacts to the user’s process control equipment are made at terminal

block TB2 on the rear of the analyzer chassis. The fault relay contacts are voltage-free Form B relay

contacts, SPST, 5A @ 250 VAC, 5A @ 30 VDC. Connect the terminal pins in accordance with the

schematic shown on the terminal ID label on the top of the analyzer chassis.

2.1.3.5 Heater OK relay output

Connections from the Heater OK relay contacts to the user’s process control equipment are made at

terminal block TB2 on the rear of the analyzer chassis. The heater OK relay contacts are voltage-free

Form B relay contacts, SPST, 5A @ 250 VAC, 5A @ 30 VDC. Connect the terminal pins in accordance

with the schematic shown on the terminal ID label on the top of the analyzer chassis.
