Trace Oxygen Analyzer	Installation

•Actuates when DC power supplied to circuits is unacceptable in one or more parameters. Permanently configured as failsafe and latching. Cannot be defeated. Actuates if self test fails.

•(Reset by pressing button to remove power. Then press again and any other button EXCEPT System to resume.

•Further detail can be found in Chapter 4, Section 4-5.

Digital Remote Cal Inputs: Accept 0 V (off) or 24 VDC (on) inputs for remote control of calibration. (See Remote Calibration Protocol below.) See Table 3-3 for pin connections.

Zero: Floating input. 5 to 24 V input across the + and – pins puts the analyzer into the Zero mode. Either side may be grounded at the source of the signal. 0 to 1 volt across the terminals allows Zero mode to terminate when done. A synchronous signal must open and close the external zero valve appropriately. See Remote Probe Connector. (The –C option internal valves operate automatically.)
