5. POWER SUPPLY UNIT AND INPUT
FA, FB: Fuse alarm output signal (B1 to B3)
A short circuit occurs between FA and FB if the fuse used in the
power unit of the NC blows or if an overvoltage or overcurrent is
detected at the DC output of the power unit. FA and FB are also
short–circuited if an alarm signal is input from AL. The fuse alarm
signal is maintained until the power being supplied to the NC is
turned off or the OFF button is pressed.
When this signal is output, the NC power is turned off and the
POWER ON and EXTERNAL POWER ON buttons are
invalidated. The connection is as follows:
Contact voltage rating
DC 50V or lower
DC 0.5V or lower
AC 50A or lower
AC 5VAor lower
Fuse alarm signal
(c) Connector CPD2B (AMP Housing 2–178129–6, Contact
This terminal is used for the control signals that turn on and off the
main locker power. The connection to the main cabinet is
completed at the factory.
(d)Connector CPD2C (AMP Housing 2–178129–6, Contact
This terminal is for the control signals that turn on and off the
additional locker power. The connection to the additional cabinet
is completed at the factory.
CP91 to CP96 (connector: FCI Japan, housing: SMS3PK–5, contact:
RC16M–23T3 or RC16M–SCT3)
(a) Connector CP91
This terminal is for ON/OFF–controlled, single–phase 200/220
VAC input. This connection is completed at the factory.
This terminal is connected to the 200A and 200B terminals of
terminal unit TB2.
(c) Connector CP93
This terminal is for power supply (120 W) to the cooling fan of the
When the cabinet is equipped with a built–in tape reader, this
terminal is connected to the tape reader at the factory. When the
tape reader is installed outside the cabinet, this terminal is used for
