3.3.3 Alarm Connections

The Model 6750 is equipped with two concentration alarms and one analyzer malfunction alarm. The three alarm-circuit connectors use spring terminals for making connections to internal alarm relay connects. Each alarm provides a set of Form C contact with both normally open and normally closed contact connections. The contact connections are indicated by diagrams on the rear panel. They are capable of switching up to 3 amperes at 250 VAC into a resistive load. See “As Built Drawings” in the Appendix. The connections are:

•Threshold Alarms:

•Can be configured as high (actuates when concentration is above setpoint), or low (actuates when concentration is below threshold).

•Can be configured as failsafe or non-failsafe.

•Can be configured as latching or non-latching

•Malfunction Alarm

3.3.4RS-232 Serial Connection

An RS-232 port is provided for serial communication (MODBUS). Connect a standard RS-232 cable from the computer to the RS-232 port on the main board.

3.4 Gas/liquid Connections

Refer to the “As Built Drawings” in the Appendix for details and Figure 3-5.

The Model 6750 Analyzer provides easy access for liquid, gas, vent and drain connections.

3.4.1 Liquid Connections

Liquid phase sample connections include the following: (See Figure 3-5):

•Sample (On-Line)

•D. I./Dilution Water

•Calibration Standard
