3. Troubleshooting with TICU installation
3-1. Input power problem
1) Phenomenon
All LEDs are off status after Power ON.
2) Corrective Action
(1)Connect the - terminal of DMM to RTN(Red) marked pin on TICU front panel.
(2)Connect the + terminal of DMM to –48V(Blk) marked pin on TICU front panel.
(3)And check that the input DC voltage is in the range -36~-60V.
(4)If the input DC voltage is not in the range -36~-60V, check the PDU unit status of RAS rack.
(5)If the input DC voltage is in the range +36~+60V, please twist the cable from RAS rack.
(6)If the input DC voltage is in the range -36~-60V, check that the POWER switch is exactly ON status.
(7)If the switch is normal and the input DC voltage is in the range -36~-60V with no operation of all LEDs, contact us. Refer to chapter 5 about the contact information.

2) Corrective Action
(1)Connect the - terminal of DMM to surface of QMA connector on 0, 0, 0,1, 1, and 1 port in TICU front panel.
(2)Connect the + terminal of DMM to center pin of QMA connector on 0, 0, 0,1, 1, and 1 port in TICU front panel.
(3)Check the output DC voltage of +14.3~+16V.
(4)If the input DC voltage is not in the range +14.3~+16V, check that the PWR led on TICU front panel is ON status.
(5)If the PWR led is not ON status, please turn on POWER switch.
(6)If the PWR led is normal and no output power, contact us.
Figure 3-2. No output power
3-3. Ethernet link problem between PC and TICU
1) Phenomenon

4-1. Communication Error in WEB GUI
1) Phenomenon
There is no response when you are typing 192.168.0.2 in Internet explorer.
2) Corrective Action
(1)First of all, check the Ethernet cable status and the LINK led status of TICU.
(2)And then check that Device scan process is now processing. Please be cautious that there is no response from TICU during device scan process.
(3)The first device scan process will start 5 seconds later after power ON. And then next device scan process will start every 20 minutes.
(4)The normal scanning time is illustrated below. It might be different according to the combination of the unique ID of ALDs. The maximum time of Device scan is about 5 minutes. This is only the case of the first scan process.
-. No ALD: about 5 seconds
-. 2 ALDs: about 45 seconds
-. 4 ALDs: about 1minute 25 seconds
-. 6 ALDs: about 2minute 5 seconds
(5)The cable and LED status are abnormal, please replace the cable.
(6)If the status is normal, check the network configuration of your laptop PC.
(7)If you click the properties of Local Area Connection, figure 4-1-2 will be showed.
(8)And then select the item Internet Protocol (TCP/IP).
(9)And then click the Properties button.
(10)Verify the IP address setting is same as figure 4-1-3.
(11)If not, please set the IP address setting like as figure 4-1-3.
Figure 4-1-1. Network Connections
Figure 4-1-2. Local Area Connection Properties
(12)And then execute ping test in command prompt window. If there is normal response from TICU, the windows will be like as figure 4-1-4.
Figure 4-1-3. Internet Protocol(TCP/IP) Properties
Figure 4-1-4. Ping test: normal response
(13)If there is no response from TICU, the windows will be like as figure 4-1-5. Retry the action from 4) to 9) with another laptop PC.
Figure 4-1-5. Ping test: No response
(14)The main window like as figure 4-1-6 will be showed when you typed 192.168.0.2in Internet exploer with TICU normal operation.

4-2. Calibration problem of RET device
1) Phenomenon
There is no response when you clicked Calibration button in figure 4-2.
2) Corrective Action
(1)If there is no response when you clicked Calibration button in figure 4-2, the actuator jam might be happened.
(2)If there is any problem during calibration process, the alarm Actuator Jam and Not calibrated will be happened.
(3)The usual calibration time might be about 20 seconds depending on the current motor position.
(4)If there is no response after 30 seconds, please check the current alarm status by clicking Get Alarm Status button.
(5)If there is any alarm status reported, please refer table 4-2. And then follow the corrective action in the table.
