6.2.12 Alarm Delivery Circuit
It is a circuit that sends failure status that occurs in the rectifier module to the control unit, and alarm
is sent when there’s disorder in rectifier module (excessive voltage of output, short circuit), excessive
discharge of a short battery, and disorder in alternating current input (power failure or when it strays
from the allowed range).
7. Control Module (DIRC-4)
7.1 Control Module Function
7.1.1 Monitoring Operation Range
DIRC-4 control UNIT can monitor operation of maximum 3 of control modules (DRM-440).
7.1.2 Alarm Function
7.1.2.1 AC Input Fail
It occurs when Input AC voltage of rectifier less than 180V and more than 280V.
LED turns to red light at the front panel.
7.1.2.2 DC High Voltage
It occurs when output voltage of rectifier is more than 58.0V. LED turns to red light at the front
panel.
Changing setting value to Debug Port and SNMP is possible.
7.1.2.3 DC Low Voltage
It occurs when output voltage of rectifier is less than 48.0V. MAJOR LED is on at the front panel.
Changing setting value to Debug Port and SNMP is possible.
7.1.2.4 DRM-440H44R0 Rectifier Unit Fail
Fail occurs if it does not operate after unit installment or unit itself fails while operation.
MAJOR LED is on at the front panel.
7.1.3 Deliver rectifier measuring data and alarm data to TCP/IP or SNMP.
