The terminal designations for the
A2
alarm outputs are:
Figure 22 – Terminal Designations for A2 Alarm Outputs
The
A2
alarm outputs are DPDT relays, 1 open collector output (
A2-OC
) that follows the
logic of the relays and 1 open collector output (
LA2
) that follows the blinking pattern of
the front panel LED. The A2-C1 designation is common for A2-1 & A2-2. The A2-C2
designation is common for A2-3 & A2-4. The normally open (
NO
) and normally closed
(
NC
) contacts depend on a user selectable option (see Chapter 5). The table below
refers to the proper open and closed
A2
alarm relay contacts while the unit is on power:
