Fault codes in this document
AS1668 Fan Faults
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Mechanical Services Board Fault | Fault indicated on the AS1668 fan control — the amber "FLT" LED turns ON. | The Mechanical Services Board sends a fault (e.g. mains failure) to the Multi-Point I/O; the Multi-Point I/O sends the fault condition to the panel. | The panel controls the AS1668 module to turn the amber "FLT" LED to ON. | 68 |
| AS1668 Fan Start Failure | Fan has been commanded to start but airflow is not confirmed — the amber Fault LED turns ON. | The panel sends to the Multi-Point I/O a control to close the relay that starts the fan (e.g. as a result of manual start or auto start), but the air flow sensor in the duct does not send to the panel an indication that the air flow is ON; after a programmable delay, to allow the fan to speed up. | The panel controls the AS1668 module to turn the amber Fault LED to ON. | 68 |
| AS1668 Fan Stop Failure | Fan has been commanded to stop but airflow is still present — the amber Fault LED turns ON. | The panel sends to the Multi-Point I/O a control to open the relay that stops the fan, but the air flow sensor in the duct does not send to the panel an indication via the Multi-Point I/O that the air flow is OFF; after a programmable delay, to allow the fan to slow down. | The panel controls the AS1668 module to turn the Amber Fault LED to ON. | 68 |
Upgrading an Existing Configuration
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| the existing configuration is an incompatible version | A panel with a non-matching configuration reports that the existing configuration is an incompatible version and repeatedly restarts. | The configuration was prepared/edited using a version of the programmer that does not match the Panel Exec firmware installed — e.g. the panel Exec firmware was updated (to add some new features) and the configuration was not upgraded using the new compatible programmer version. | Upgrade the configuration using the new compatible programmer version and download it to the panel after the firmware has been updated. The upgraded version of the configuration must be downloaded before normal operation will resume. | 17 |
