Alarms

The alarms port interface is a standard DB15-pin connector (see Figure 12-1). This connector allows remote
display of alarm conditions. Each alarm (major, minor, critical and power) is the output of a STDT relay
contact. A common contact with normally open and normally closed connections is included. The power
alarm has just common and normally open contact outputs. The major and minor alarms contain external
reset circuits. Table 12-1 gives the pinout of the alarms connector.
CAUTION Do not apply more than 60 Volts (maximum) to any pin or combination of pins on the alarms
connector.
