Verifying Cartop Voltages - MCi iControl User Manual

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 initial pages of the -CT drawings where power connections are primarily
shown. On the cartop, verify all voltages shown are present and within acceptable levels
with respect to ground.
• +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 iLink 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.)
Figure 3.3 iLink CTP Board Diagnostic LEDs
LED 1: iBox to cartop input.
Blinks approx. every 40mS.
Remains OFF if input lost.
LED 2: Unintended motion
indication. Normally OFF.
LED 3: Unintended motion
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.
LED 7: Not used.
LED 8: Not used.
8. Install the cover on the iLink cartop interconnect box.
9. Verify that the iBox CARTOP LED is ON indicting that the iLink CTP board is communi-
cating with the iBox. If not, verify that the CARTOP LINK wiring is connected as speci-
fied on the job prints. Additional troubleshooting information is available in Section 6.
