Cellwatch Frontier System Installation & User Manual

Section II – User Guide-87

Tests and Actions

 DCM Data: This tool allows users to interrogate DCM devices individually to gather the most up-

to-date readings and information.

 Ping Channels in Alarm: Use this feature to activate the LED and buzzer on DCM units

connected to channels in alarm.

 Manual Ohmic Scans: This function allows users to initiate an ohmic value scan. The option to

scan the entire system or individual strings is available.

 Resume Scan: This activates the scan routine again following a system stop due to fiber break or

maintenance.

 Test Hardware Relays: Activate individual relays to verify proper configuration.

 Test Fiber Optic Loop: Users can perform a fiber optic check. During this check, a pulse will be

transmitted through the fiber optic loop once per second. All DCMs that receive the signal will

beep, flash, and pass the signal to the next DCM until the signal is returned to the Frontier

module. This test can be used to troubleshoot a break in the fiber optic loop of a Frontier system

by using the DCM units to identify where the break has occurred in the loop.

 View logs: Lists all log files that are available for download. Can be used to troubleshoot issues

and investigate events.

 Scaling Factor: Click to set or clear ohmic value scaling factors on cells, straps or charger cables.

 Device Restart: Click this button to restart the Frontier device.

Troubleshooting

This section will address the most common errors reported by the Frontier system and solutions for

each.

Channel Mismatch Error

DCM fiber loop is complete, but channels detected do not match the number of channels configured.

Resolution: Check the fiber loop. Likely a DCM was skipped when routing fiber. Also check the

configuration to ensure it is correct.

DCM Error

Indicates there is a break in the fiber loop.

Resolution: Check fiber loop using Test Fiber Optic Loop in Diagnostics. Likely a fiber connection isn’t

secure, or a DCM is not regenerating the fiber signal.
