FlexES Trouble Codes

The system has detected excessive resistance (> 200 mOhm) at the battery terminals or cables.

The FACP indicates a fault when battery resistance is too high, voltage drops below the discharging limit, or a connection/fuse issue is detected.

The system has detected an unintended connection to ground or an incorrect configuration of the earth fault detection jumpers on multiple power supply modules.

A break or wiring error has been detected in the essernet communication loop.

A device on the essernet is not receiving power or is completely disconnected.

Physical damage to the essernet 500 kBd line, often due to installation errors.

Signal strength is too low due to excessive loop length or high cable resistance.

Internal hardware failure detected within the essernet module.

The primary 230 V AC power source is missing or has failed.

A condition indicating a short circuit or interruption on the connection line, which may cause the system to isolate segments of the loop using group separators.

Incorrect setting of the essernet address on the DIL switch of the essernet module.

The system has detected that a housing panel or door has been opened or tampered with.

The tamper contact is used to monitor whether the control panel's housing has been opened and can be used to automatically deactivate components for servicing.

The essernet module has detected an invalid or conflicting address configuration after a restart.
