Gen1 - Installation Deici Icarus 40.17 Gen 1 to Gen 3 - System Test

Notes
The Gen3 LMS system is now installed. The components now need to be tested to ensure everything has been properly installed and is functioning correctly. 

System Test
Power the system from the machine's ignition key switch. After about 10 seconds the display will load with the boot screen then the main screen. If the screen does not load check the power connections.

Once the main screen has loaded navigate to the on screen diagnostics menu. Press the user control dial to enter the menu system, rotate the dial to highlight a menu option and press the dial to select the option.

Select the following menu options to access the diagnostics screen:
System Menu → Diagnostics Menu 

The diagnostics menu displays the raw sensor values and switch states for the Gen3 LMS system and verifies that all sensors and switch inputs are operating correctly. The first items displayed on the diagnostics menu are the pressure sensor values. This is the raw reading from the pressure sensors installed in the main lift cylinder, the values are between 0 – 4096.

Move the boom to about 0 degrees then raise the boom up to about 20 degrees and note the main head and main rod pressure sensor values. The main head pressure should be a value greater than 100 and the main rod value should be a small number and may be 0.

Lower the boom back down to about 0 degrees. The main rod value should have increased dramatically compared to when the boom was raised. The main head value should have also increased in response to the increase in the main rod pressure. Since the hydraulic oil in the rod of the cylinder is not locked behind the counterbalance valve the rod pressure value will start to immediately decrease after the boom lower action is completed. This loss of hydraulic pressure from the rod of the cylinder will start to relieve the pressure on the head of the cylinder, resulting in a decrease of the head pressure value as well.

Slowly tilt the attachment head up and while tilting - note the compensation head and rod values. When tilting up the compensation head value should be greater than the compensation rod value. Slowly tilt the attachment head down and while tilting - note the compensation head and rod values. When tilting down the compensation rod value should be greater than the compensation head value.

If any of the above pressure sensor tests did not return the expected result, its likely that one the of the pressure sensor inputs may have been swapped. There is also no sensor connected to the axillary pressure input so this will also be 0. The boom angle value displays the raw boom angle in 0.1 degree units. Note the current boom angle value, then raise the boom, the boom angle reading should increase. The carrier angle values display the raw carrier angles for both the X and Y axes in 0.1 degree units. Both carrier angle values should be close to 0 and can be negative.

The boom length value displays the boom length pulse count reading. Fully retracted the boom, the value should be 500 when the boom is stowed (fully retracted). If the value is not 500 then the boom stow switch is not being triggered correctly and will need to be adjusted, see Gen3 - Fault Code - N07 to learn how to that's done. Extend the boom and the boom length value will increase. Retract the boom angle the boom length value will decrease, until the boom is stowed and the value will read 500.

The remaining display items in the diagnostics menu are digital input on/off signals. If the input signal is inverted (eg. The forward gear signal shows inactive when the machine is in forward gear and shows active when the machine is in neutral) the signal polarity can be changed, contact EQSS for details on changing the input signal polarities. The forward and reverse gear signal values will be active when in the respective gear. Place the machine into forward gear the forward gear signal will be active and the reverse gear signal will be inactive.

Place the machine into reverse gear the reverse gear signal will be active and the forward gear signal will be inactive. If the respective gear signals do not switch to active and the signal is not inverted then either the signal line has not been connected correctly or the diode polarity needs to be reversed. The override signal will be active when the override switch is triggered. Press the override switch and the override signal will be active. If the override signal does not switch to active then either the signal line has not been connected correctly or the diode polarity needs to be reversed. The left and right stabiliser down signal values will be active when the respective stabiliser has been lowered, unless the signal is inverted. Depending on how the stabiliser switches have been installed, both the left and right stabilisers may need to be fully lowered for both signal values to change to active. If limit switches were installed and both stabilisers are fully lowered then the switch arm may need to be adjusted. Return from the diagnostics menu and enter the system tests menu

The below options will become available


The 'System Tests' enables outputs testing within the Gen3 LMS system. To engage a system test, highlight the desired test from the menu. Press the user control dial and the highlight will change colour, indicating that the test output is currently active. Press the user control dial again to end the test and return to normal function.

The first test is the primary cutout. When this test is engaged the hydraulic cutout is  activated. Ensure the boom can only be raised and retracted if an aggravated movement cutout is fitted or that all boom functions are disabled (if a full cutout is fitted). If the cutout is inverted, meaning the cutout is active when the test is not engaged and normal operation when the test is engaged, contact EQSS for details on changing the output signal polarities. If the cutout signal is inverted the Gen3 LMS will produce a cutout for the first 10 seconds after startup while the system is loading, some machine electronics perform a test at startup on the cutout system and may produce an error if the cutout is initially engaged during startup.

Changing the cutout signal polarity is not recommended, since some machines perform a system check of the cutout signal during startup. The raise and lower cutout functions are not used and will not change the machine functionality if they are engaged. The light tower test function turns on all the lights or each light individually on the light tower to check the lights are functioning correctly. The green and orange lights will be solid and the red light will flash. Once all the tests have been completed. Finalise the installation by stowing any loose cabling and reinstall all the covers. The next step is to complete the load calibration for each attachment and the velocity calibration. Install the Gen3 Calibration Tool, contact EQSS if software installation instructions haven’t been provided. Read the pdf User Manual (installed with the software and the Gen3 Calibration Tool), to perform the load and velocity calibrations. 
Notes
The diagnostics menu is displayed across multiple pages, scroll up and down using the user control dial to access the different pages 
Info
Some machines have an economy mode that switches off the accessories after a while if the engine is not active. Turn the engine on to ensure the Gen3 LMS remains powered while testing.
