Fuse Alarm Test
Introduction If there are any site installed fuses, they can be tested for alarm
functionality by generating alarms for the controller at these points. If
this is not possible, they can be tested by simulating alarm conditions at
the BSL board (see Figure 3-1) on the Millennium Controller by
following the steps given below.
Major Fuse Alarm
(FAJ)
Connect a jumper (through a 1K resistor) between Pin 63 (FAJ) and
Pin 93 (ABS) on BSL Board (see Tables 3B, 3C and 3D in the
Millennium controller manual for details of these pin assignments).
DIST and MAJ LEDs will light up. MJF default relay will be activated.
For GPS cabinets, fuse alarms may be simulated at the BNL1 or BL7
alarm card by strapping FAJ on these cards to the hot bus (P4-1 for
BNL1, P5-6 for BNL7).
Minor Fuse Alarm
(FAN)
Connect a jumper (through a 1K resistor) between Pin 65 (FAN) and
Pin 93 (ABS) on BSL Board (see Tables 3B, 3C, and 3D in the
Millennium controller manual for details of these pin assignments).
DIST and MIN LEDs will light up. MNF default relay will be activated.
