4.1.2.1. Input/output (I/O) interface
The input/output interface on the Controller CIP consists of:
•
one input port for the detection of external alarm:
•
three output ports driven by relays with dry- C contacts (see Figure 5.1
for the specific position of these dry-C contacts):
Major alarms (MJ)
Minor alarms (MN)
Observation alarms (O1): AC supply failed or out of range, or
ongoing Battery On Discharge alarm, or ongoing Low Voltage alarm
Note:
The Major output dry-C contact is fail-safe. In case of a power
failure, it will be released, providing continuity through the normally close
contact and open circuit through the normally open contact.
4.1.2.2. Alarms
The Controller CIP displays its own operating status by means of the
“Controller Status” LED indicator located on the front panel.
•
Green means that the unit is operating normally.
•
Red means that the unit is not operating normally.
It also displays the system alarms by means of the “Minor” and “Major” LED
indicators also located on the front panel (refer to Table 7.1):
•
the yellow Minor LED indicates that there is one or more minor
alarm(s) activated in the system, but no major alarm,
•

activated in the system.
Refer to Figure 3.10 for the specific location of the LED indicators.
