TC 1280 / TC 1380: 'ERR 57' after power up and delay settings lost

Question

I have a TC 1280 that currently needs to be input with the correct delay time as each time it powers up, it shows ERR 57 and does not have the correct setting, however, it does not do that when it is instantly off and then on. What is the reason?

Answer

This is likely to be caused by a bad back-up battery in your TC1280.

The battery is soldered into the mainboard and should be replaced by a skilled technician.
The TC order code for a battery is: 342000011 LITHIUM BATTERY 3V/200mA. CR2032RV

You can order a battery at your TC Electronic dealer, distibutor or service centre.
