Verifying Cartop Voltages
1. Set the iBox Inspection switch to the INSP position.
2. Set the Controller Stop switch to the Stop position.
3. Turn on power at the main disconnect.
4. Watch the front panel displays of the iBox, the controller will take about 60 seconds to
initialize.
5. Check the Computer, Safety A, Safety B, and Cartop status LEDs. The LEDs should be
lighted solid green.
6. Refer to the -CT drawings for power connections. On the cartop, verify all voltages
shown are present and within acceptable levels.
• +5V, +/-15V, +/-26V, +3.3V test points are on the right edge of the ICE-CTP board
• The GND test point is in the middle of the ICE-CTP board
• Verify 2 and 3 bus power with respect to the 1 (common) bus
7. Verify the eight diagnostic LEDs on the CTP board. (On power up or reset, these LEDs
will light sequentially, first in one direction, then the other, after which they will briefly
clear. See the illustration below for normal operating indications.)

8. Install the cover on the iLink cartop box.
9. Verify the iBox CARTOP LED is ON indicting that the iLink CTP board is communicat-
ing with the iBox. If not, verify that the CARTOP LINK wiring is connected as specified
on the job prints. Additional troubleshooting information is available in Section 6.
Please refer to “iControl Circuit Board Quick References” on page 6-82 .

indication. Normally OFF.
LED 4: Cartop to iBox output.
Blinks approx. every 40mS.
Remains OFF if output lost.
LED 5: Blinks every 40mS.
LED 6: ON for Inspection
mode. OFF otherwise.
