Your RF5xx Transmitter displays message ‘COdE 500’ on the LCD screen, similar to that shown here. This code is only seen on RF5xx Transmitters with Firmware Version 3.0.0 or higher.
This ‘COdE 500’ indicates a combination of two user repairable faults with the Transmitter.
- (COdE 100) – The Clock has not been set on this device
- (COdE 400) – Invalid programmed task on the device
If the Transmitter Battery has recently been replaced
If the Transmitter Battery has recently been replaced, then this might be the cause of the perceived loss of date/time, as well as the Task related issue. To rectify both issues, remove the battery again. Once removed, allow the LCD on the Transmitter to clear/blank, before re-fitting the battery. To re-fit the battery, place the battery into the holder and snap into place in one quick movement. The LCD on the Transmitter should then go through a start up process, first showing a checksum, before starting normally. Should the Transmitter display another ‘COdE ???’ message after this, then please refer to the Knowledge Base article for that message for further guidance.
If the Transmitter Battery has NOT been recently replaced
To resolve this issue you will need to re-task the device. Unfortunately, if your Transmitter hasn’t sent any data since going into the error state, then that data will be lost when the unit is re-tasked.
To re-task a Transmitter, simply log on to the Gateway, locate the relevant Transmitter on the Homepage and click on the Summary Graph. Once on the ‘Summary’ page, click the ‘Task’ icon. You should double-check the settings for the task, before clicking on ‘Program Task’ (or ‘Program’).
Please allow up to half an hour for the Task to be successfully sent to the Transmitter, assuming a 15 minute radio rate. If required, you can speed the process up by ‘provoking’ the Transmitter using an RF525 Transmitter Activator.
If the ‘COdE 500’ message persists, even after re-tasking the Transmitter, then you should look to have it serviced.
Additional Fault Codes
On occasion, your ‘COdE 500’ message may be appended by an additional ‘Fault’ code. If you are seeing a fault message, ending in either a 1, 2, 4 or an 8, then the above will still apply, but you should refer to the Knowledge Base articles for that Fault references as well;
