⚠️ READ BEFORE COMMISSIONING CHEVRON SYSTEM ⚠️
To fully commission your chevron equipped MX system, the MX Field App is required. The MX Field App wirelessly communicates with MX systems for programming, configuration and diagnostics. It utilizes the Bluetooth connection between your mobile device and the MX system. Once you download the app, a cellular or Wi-Fi connection to the internet is required to create and sign into your Profile. The MX Field App allows for system programming, scheduling, firmware updates and diagnostics from the ground without having to manually access the system. The MX Field App is available free of charge on the Apple App Store and Google Play Store for compatible mobile devices. For more information see carmanah.com/app. Ensure you are running the latest version of the app before starting the commissioning.

1.1 Chevron Overview
For chevron warning sign applications, follow commissioning steps outlined in this document. Once you have completed a site survey, proceed with setup based on your application and requirements.
? Chevron warning signs will flash continuously by default using the Always On operating mode.
General Installation Notes
- Installation can be unidirectional or bidirectional.
- Maximum of ten chevron systems in total can be linked with each other.
- Line of site from one power module to next adjacent system is required for proper wireless communication.
- Flasher module maximum distance is 75' away hardwired to its power module.
- Site survey (Section 1.3) should be completed for each installation.
- Chevron systems are identified from left to right when performing site survey.
- Left Leader = first position (system) from the left.
- Right Leader = last position (system) from the left.
- During initial setup (Section 1.4), systems should be renamed for easy identification.
- Flasher side is identified as you approach the system:
- Left = vehicles approach chevron sign on left or installed on left side of pole.
- Right = vehicles approach chevron sign on right or installed on right side of pole.
- N/A = only one chevron sign installed.
- Radar, if equipped, must be installed on Left Leader and/or Right Leader only.
- Sequential flashing can be split into “subgroups,” typically used for large curves containing six or more chevron systems.
1.2 Typical Site Layout
Refer to MX Chevron Overview below for a typical site layout. Orient site as shown from left to right as viewed from across the street.
The diagram illustrates a typical Carmanah MX Series Chevron System installation along a curved road. It depicts four MX Systems, numbered 1 through 4 from left to right, representing the sequence of installation. System 1 is designated as the 'Left Leader' and System 4 as the 'Right Leader'. Each system pole is shown with either a 'Left Side Flasher' or 'Right Side Flasher' indicator. Optional 'Radar' modules are depicted as being installed on the Left Leader and Right Leader systems.
Example and Terminology
The following describes elements seen in the mobile application interface during setup:
- System Screen: Displays overall system status, operation mode, system name, and system type.
- Chevron Configuration Menu: Provides access to overview, setup, individual system settings, flasher side, and flash pattern settings.
- Individual System Configuration: Allows setting of 'Position', 'Left Leader', 'Right Leader', 'Radar', 'Individual System Settings', 'Flasher Side', and 'Flash Pattern Settings' for each MX System.
1.3 Site Survey
Fill in table below for each system on site.
Recommended new system name = XXXX YYYY ZZ
- XXXX = last four digits of system serial number
- YYYY = Position # (POS1)
- ZZ = Left Leader (LL) or Right Leader (RL); if applicable
| Position (POS) | Default System Name | New System Name | Left Side Chevron S/N | Right Side Chevron S/N | Radar Equipped? |
| EXAMPLE | MX123456789 | 6789 POS1 LL | 2401234567 | 2401234568 | Yes |
| EXAMPLE | MX123456790 | 6790 POS2 | 2401234569 | 2401234570 | No |
| EXAMPLE | MX123456791 | 6791 POS3 RL | 2401234571 | 2401234572 | No |

? Table will be filled in as part of the setup in Section 1.4.
1.4 Initial Setup
- Connect to system designated as POS1 (Left Leader).
- Use "Identify System" button [identify icon] to confirm you are connected to the correct system.
- Rename system as per recommendations in Section 1.3.
- Change Operation Mode to Trigger/Standby.
- Change System Type to Chevron Sign.
- Tap on Link Settings and then [vertical ellipsis].
- Tap on Custom Link and then Apply Link Settings.
- Repeat step 1 for all remaining systems. Once reaching step 1e for each system, tap on Paste Link and then choose Copied Settings from system POS1. Once complete, systems should:
- Be named accordingly.
- Be set to same Operation Mode and System Type.
- Be linked together.
- Proceed to Section 1.5.
? Chevron systems can be programmed for 24-hour flashing, dusk-to-dawn flashing, or radar triggered. Only Left Leader and/or Right Leader can be radar equipped.
? If radar equipped, systems will flash as vehicles are detected while completing setup.
1.5 Configuration
- Connect to POS1 system.
- Open Chevron Configuration menu.
- Tap on Individual System Settings and set each parameter based on your installation.
- Set Radar to N/A if system is not radar equipped.
- Tap Save to complete.
- Tap on Flasher Side and set chevron sign configuration.
- If you are unsure which flasher is which, use the "Test" button [test icon] to confirm.
- Set to N/A for systems with one chevron sign per pole.
- Tap Save to complete.
- Connect to each remaining system and repeat steps 1 – 4.
- Last system in sequence should be assigned as Right Leader if radar is equipped.
- While still connected to last system in sequence, tap on Flash Pattern Settings.
- All linked systems and positions should be listed accordingly. Confirm this is accurate based on site survey and setup.
- Tap on "edit" button [edit icon].
- Adjust each setting based on your application.
- Section 1.6 - Synchronized Flashing
- Section 1.7 - Sequential Flashing
