Issues at Initial Startup or After a System Restart
THE iDRIVE CANbus NETWORK FAILS TO INITIALIZE, OR DROPS OUT AFTER A SHORT PE-
RIOD OF OPERATION.
WHAT TO LOOK FOR
- A failure of COURION’s iSYSTEM CANbus Network can be identified in a variety of ways:
• The iLEARN Door Control Boot Screen indicates that the number of iDRIVEs found are LESS than the number of
iDRIVEs expected.
• The iDRIVE Network LED Lights (RX & TX) on the iLEARN Door Control are on STEADY. This is a result of the
iLEARN transmitting but there are no iDRIVEs (CAN transceivers) acknowledging.
• The iDRIVE Network LED Lights (RX & TX) on the iLEARN Door Control are rapidly flashing, but are dim. This is
a result of the iLEARN transmitting and at least one iDRIVE (CAN transceiver) is acknowledging. However, the
iLEARN is receiving less acknowledgements that expected.
• The iDRIVE Network LED Lights (RX & TX) on one or more iDRIVE VFD Floor Control are not rapidly flashing.
• Error 01 - NUM OF iDRIVEs appears on the iLEARN Door Control.
• Error 02 - iDRIVE COMMs appears on the iLEARN Door Control.
• Error 16 - GATE ERROR COMMS appears on the iLEARN Door Control.
Step 1
: Check the iLEARN Door Control Parameters to insure that you have entered the correct # of iDRIVEs, Car
Gates, and Car Stations. See Initial Start-Up and Adjustment Section of this Manual for further information.
Step 2
: Check all of your CANbus communication wiring at the iLEARN Door Control and each iDRIVE VFD Floor
Control to insure that there are no loose connections or mis-wired communication ports on C01 (24VDC), C02 (COM-
MON), C03 (CANH), C04 (CANL), C05 (Address In), and C06 (Address Out). Also insure that your twisted-pair shield-
ing is continuous throughout the CANbus Network (from iLEARN Door Control to car top Gate iDRIVE(s)) and properly
grounded in the machine room.
Step 3
: Disconnect the CANbus connector from the Gate iDRIVE PLC(s) and change the # of GATES Parameter to
zero. Reboot the System by recycling the 240VAC and 120VAC power at the disconnect switches. If the iSYSTEM
finds the expected number of iDRIVES, then the CANbus Network problem is probably isolated to the car top. If the
iSYSTEM does not find the expected number of iDRIVES, then the CANbus Network problem is probably in the hoist-
way wiring.
Step 4
: Remove the 240VAC and 120VAC power to the iDRIVE(s) and iLEARN at the disconnect switch(s). Unplug all
CANbus terminal block connectors from all Door and Gate iDRIVE(s). Leaving the 240VAC OFF, turn the 120VAC power
back on to the iLEARN Door Control. With a digital voltmeter set to automatic range, take the following readings at
BOTH the iLEARN Door Control and the Gate iDRIVE PLC (Front) to insure that you have the correct network voltage:
• Red to C01 (24V) and Black to C02 (COMMON) = +21.6VDC to +26.4VDC
• Red to C03 (CANH) and Black to C02 (COMMON) = +2.6VDC to +2.8VDC
• Red to C04 (CANL) and Black to C02 (COMMON) = +2.0VDC to +2.2VDC
• Red to C05 (Address In) and Black to C02 (COMMON) = 0VDC
• Red to C06 (Address Out) and Black to C02 (COMMON) = +21.6VDC TO +26.4VDC
• Red to C03 (CANH) and Black to C04 (CANL) = this will be a positive (+) value in the tens to hundreds of mil-
livolts range. If this is 0VDC, then there are absolutely no network transceivers sending data. If this is ever
measured to be a negative voltage, the CANH and CANL lines are reversed.
