Rocky Mountain Crane Service Logs
Installed a new memory stick in the swing drive on Igo T85A. Had to go to menu 74 and then to 11 to set the Supply Voltage to get started.
Then had to restart the drive and it went through a motor ID and run ID test. Once complete, had to restart the drive again and it worked fine. The drive said it was ready to work, but was unresponsive. Make sure to restart again.
Customer complained that the AC power in the cab was not working. When asked, the customer still had lighting, but the AC plug ins were not working. Found that the circuit breaker Q104F was tripped.
**note** when circuit breaker was tripped the indicator was green. When it is working, the indicator is red
These are 480 volt wires! Insure all power to crane is shut off!
Jumper P strip 1 to 2 and 3 to 4 (all should have continuity)
When replacing the radio remote receiver on HUP, had to go into CCS and enter address and group of transmitter (radio remote).
When you turn on the remote, the screen stays on the page showing group and address. Go to Mounting>Configuration>Radio Control (6-2-6) and enter both group and address. Once complete press ENTER and look for the check mark. ESC, ESC, ESC and press start button
Here are the instructions for derating the moment and max thresholds
When 24V system shorted out, computer reset to 00/00/00 and 00:00.
Go into system date to set time and date, and then can change General Preferences to region time.
Serial number 602585
Justen from CLS called and said the remote was showing Comm Error. Talking with Tomas, it is the data being sent from receiver to the remote (transmitter) for the display. Check the connection at the receiver with the red antenna for loose or corrosion at the connection. Also, check inside the remote there is an antenna that can come loose or fall off. If all looks good, need to replace both receiver and transmitter.
Pictured is a standard “Wye” connection. First test is the “megger” test which measures resistance to ground. Should be 800-900 Mega ohms (MΩ) resistance (our tester reads up to 500 Mega ohms)
In theory they all share the neutral in the middle, and testing only 1 leg should be sufficient, but this isolates each leg
Next test is a resistance of the windings for each leg
Final test would be current draw on each leg, but would require an amperage clamp and ability to run motor continuously.
