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.
Threshold Alarm 1 can be configured as:
•
High (actuates when concentration is above threshold) or
low (actuates when concentration is below threshold).
•
Failsafe or Non-failsafe.
•
Latching or Non-latching.
•
Out (defeated).
Threshold Alarm 2 can be configured as :
•
High (actuates when concentration is above threshold), or
Low (actuates when concentration is below threshold).
•
Failsafe or non-failsafe
•
Latching or non-latching
•
Out (defeated).
System Alarm: 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.
