4–20 mA dc % Range: (Optional) Current increases linearly with increasing
oxygen, from 4 mA at 0 % to 20 mA at full scale.
(Full scale = 100% of range.)
4–20 mA dc Range ID: (Optional) 8 mA = Low Range, 12 mA = Medium
Range, 16 mA = High Range, 20 mA = Air Cal
Range.

Alarm Relays: The nine alarm-circuit connector pins connect to the
internal alarm relay contacts. Each set of three pins provides one set of Form
C relay contacts. Each relay has both normally open and normally closed
contact connections. The contact connections are shown in Table 3-2. They
are capable of switching up to 3 amperes at 250 V ac into a resistive load.
The connectors are:
Threshold Alarm 1: • Can be configured as high (actuates when concen-
tration is above threshold), or low (actuates when
concentration is below threshold).
• Can be configured as failsafe or nonfailsafe.
• Can be configured as latching or nonlatching.
• Can be configured out (defeated).
Threshold Alarm 2: • Can be configured as high (actuates when concen-
tration is above threshold), or low (actuates when
concentration is below threshold).
• Can be configured as failsafe or nonfailsafe.
• Can be configured as latching or nonlatching.
• Can be configured out (defeated).
System Alarm: Actuates when DC power supplied to circuits is
unacceptable in one or more parameters. Permanently
