Teledyne 9060L, Percent Oxygen Analyzer operating instructions Alarm #2

Percent Oxygen Analyzer	Installation

The alarm relay circuits are designed for failsafe operation, meaning the relays are energized during normal operation. If power fails the relays de-energize (alarms activated).

The contact connections are indicated diagrammatically on the rear panel as Normally Closed, Common, and Normally Open. Figure 3-3 explains how these act in failsafe operation.

Alarm 1 and Alarm 2 are configured as HI and LO respectively. A HI alarm will activate when concentration is above threshold, while a LO alarm will activate when concentration is below threshold.

Figure 3-3: Contact ID for FAILSAFE Relay Operation

The specific descriptions for each type of alarm are as follows:

Alarm #1	Programmable as high alarm. Can be set anywhere
	between 0 and 100 % but no lower than Alarm #2.
Alarm #2	Programmable as low alarm. Can be set anywhere
	from 0 to 100 % but no higher than Alarm #1.
Sensor Fail	Actuates when the output of the sensor falls below a
	factory programmed acceptable level or the
	thermocouple is open.
CAUTION:	THERE COULD BE HAZARDOUS VOLTAGE AT THE
	ALARMS TERMINALS, EVEN WHEN POWER IS
	REMOVED FROM THE INSTRUMENT.
