Does this device come equipped with a backup battery?
Unfortunately, this device does not come equipped with a replaceable Energy Storage Module, as it relies on a capacitor to store the program in the event of power down.
dmroeder mentioned that the machinery in question does not have a replaceable Energy Storage Module but instead uses a non-replaceable capacitor to store the program in case of power down. This system is crucial for running a baler with a generator; however, if the machinery stalls or runs low on fuel, there is a risk of losing the program. Could the capacitor be the cause of this issue?
Badboybalerman commented that using a generator to run a baler may cause program loss if the machine stalls or runs low on fuel. It is possible that the capacitor is the culprit. To address this issue, consider backing up the program to an SD card with standard capacity and setting the controller to Load Image = On Corrupt Memory. Keep in mind that this is only a temporary solution to mask the underlying problem.
I have experienced issues with multiple CompactLogix controllers losing their program during brownouts, where the input voltage to the power supply dips below normal levels. This can result in the CompactLogix losing its program.
Consider improving the protection of your programmable logic controller (PLC) or its power supply unit (PSU) by installing a surge protector or filter. We have utilized a 4983-DC in some of our control panels. This measure can help safeguard your PLC system from power surges and electrical fluctuations.
Yes, this device does come with a backup battery. It's a great feature for when there's a power outage or when you're traveling and don't have immediate access to a power source. It could be a real lifesaver in those situations.

Answer: No, the 1769-L30ER does not come equipped with a backup battery.
Answer: It is not necessary to install a backup battery for the 1769-L30ER as it does not have a built-in backup battery.
Answer: To ensure data retention in the 1769-L30ER PLC without a backup battery, you can use non-volatile memory or implement a backup power source such as an uninterruptible power supply (UPS).
