This will cause the associated service LED to flash as follows, for 21 seconds:

21s

5 Hz 5 Hz

00408

The flash memory contains the following:

(A) The firmware (the basic program used to process the applications)

(B) the D-MAP applications

ONWORKS® image (descriptive information for the RXC devices)

If the force firmware download pin is depressed during a restart or power-up, the red

status LED will light up and (B) and (C) will be deleted from the flash memory.

The system controller waits for approximately 5 s for the signal to activate the firmware

loader.

When this signal is received, the firmware (A) will also be overwritten.

At the end of this time period, the controller will start, whether or not the firmware has

been downloaded.

Commissioning on the L

ONWORKS® side (FLN)

On the field side (LONWORKS®), the RXT10 tool is used for commissioning.

• The device is addressed (enter the LONWORKS® neuron ID or press the service pin

and transmit a wink command, as above)

• The application descriptions and the address information is downloaded into the

RXC devices (.xif files)

• The mapping files in the PXR are downloaded with the bindings (via file transfer).

For a detailed description, refer to the manual for the RXT10 tool, document

CA110338.

If by mistake a physical connection exists between the two networks (FLN /

ONWORKS® and ALN / BACnet), the tool RXT10, while installing the PXR as a Master

device, will set the L

ONWORKS® nodes of the automation level to "unconfigured". As a

consequence these nodes will no longer be recognized ("not responding").

Maintenance

Lithium batteries usually have a life span of at least four years. The system controller

automatically sends a system event in order to indicate a low charge.

After the "Battery low" event there are several months of remaining life span.

To change the battery remove the front cover. As long as there is an external power

supply, the battery may be removed for unlimited time.

To prevent hardware damage by electrostatic discharge (ESD), a wrist strap with

earth cable must be used during the battery change.
