5 Powering up the system
To power up the system, complete the following steps:
1. Check that the AC power is wired to the control unit.
2. Check that the breaker controlling the circuit is off.
3. Connect the negative lead, the black wire, of the battery harness to the battery.
CAUTION: At this point, do not connect the positive lead, the red wire, of the battery harness to the battery.
4. Verify the system's wiring with a volt-ohm meter (VOM). For more information, see Wiring the 2004-9101 FACU.
5. Apply AC power.
6. Connect the positive lead, the red wire, of the battery harness to the battery's positive terminal. The piezo sounds and the display
lights, unless you have removed the depleted battery resistor. For more information on removing the depleted battery resistor,
see Enabling the FACU for depleted battery cutout.
7. On power up, the control unit performs the following actions:
- The Central Processing Unit (CPU) self-test.
- The Link Scan and checks for a programming unit connection.
- The Memory Test and verifies the system and job-specific software.
If the control unit successfully completes the start up self-test, it indicates a warm or cold start trouble that clears automatically. If
there are no other troubles in the system, the control unit displays the following indications:
- Only the green AC Power LED is steady on.
- All the rest of the LEDs are off.
If other troubles exist in the system, the control unit displays the following indications:
- The yellow system trouble LED starts blinking and continues to blink until an operator acknowledges the trouble. Press the ACK key
to acknowledge the trouble.
- If the ground or battery related troubles are present, the respective LEDs start blinking along with the system trouble LED.
- If the 2004-9101 startup self-test fails, the control unit outputs a crash code and attempts the startup sequence after 45 seconds.
