Controller Troubleshooting Tools

Here are a list of functions, built into most LC&D controllers, that can aid in troubleshooting the system:

 

Troubleshooting

Manual Override

The manual override screen is accessible through the main USER MENU. It is used to manually turn loads on and off. This screen will also tell you which loads are on, which loads are off, which loads are in the process of timing out and which loads have been issued blink warnings.

The numbers at the bottom represent all the loads within the selected panel (LCP1 in this image). If you press ENTER on a load number here, that load will toggle. A darkened box next to the load number indicates that the load is on. A dash indicates that it is off. A box with a single leg means that the load is timing out. A box with two legs means that the load has been issued a blink warning.

Read Address

Located somewhere, on every LC&D network device, is an address/assign button. In addition to being able to use this button to assign an address to the device, you can also use this button to read the currently assigned address from the device. To do this, access the READ ADDRESS menu from SETUP MENU -> SYSTEM SETUP MENU -> ADRESSING BUS SCAN -> READ ADDRESS. Press the address button on the device you wish to read the address from. Its address and serial number will be displayed on the screen.

 

Bus Scan Display

The bus scan display gives a visual representation of all detected system devices on the CAT5. This menu can be accessed through SETUP MENU -> SYSTEM SETUP MENU -> ADRESSING BUS SCAN -> BUS SCAN DISPLAY. Each digit on this display represents a system address. The addresses run left to right, top to bottom, and there are 127 total addresses. Panels are shown here as 3’s, and switches appear as 1’s. In the following display there is a panel at addresses 1 and 2. There is a switch or similar type device at addresses 4 and 5:

Scan by Serial (Scan by Factory ID)

Scan by Serial is a function that will scan that CAT5 bus, and return a list of all detected devices, their serial numbers, and address numbers. After scanning, it also informs you if there are any unaddressed devices or duplicate addresses (collisions) and allows you to reassign device addresses. This is useful because it allows you to address switches and other devices without having to physically be present at the device. Scan by Serial can be accessed through SETUP MENU -> RESTRICTED -> ADDRESSING BUS SCAN -> MORE DIAGNOSTICS -> DEVICE MANAGEMENT -> SCAN BY SERIAL. After pressing ENTER on Scan by Serial, you will see this screen:

Pressing ENTER again here, will bring you to the list of devices on that CAT5

Pressing SCROLL UP or SCROLL DOWN while the Serial # is selected will allow you to cycle through all the CAT5 devices by their serial numbers. Unaddressed devices will come up here with an address of zero. To change the address of a device, select the address number and press SCROLL UP or SCROLL DOWN to set the desired address. Select “SAVE ADDRESS CHANGES”, and press ENTER to save any address changes made at this screen.

What & When

The What & When menu has 3 sub menus:

Scheduled Events

This will display a list of all upcoming scheduled events in the time schedule for a 1 week period. It gives you details about the events, such as the group number, the time, and whether it is an ON or OFF event.

Note: This will not show if a group is controlled by a global group.

What Controls Groups

This will tell you what controls a specific group number. If you select a group here and press ENTER, it will list any switch buttons or schedules that control that group.

What Controls Relays

This screen will tell you what controls a specific relay. If you press ENTER on a load number here, it will tell you what switch buttons operate that relay. It will also tell you if that relay is part of a group, and display the group number.

Note: This will not show what relays are controlled by scene in a micro panel or what relay are controlled by a scene, this information will be found in the iDIM/iDH Menu.
