Replacement cycle:
The ERC LED on the front panel of the Loop Control Unit starts to blink when
the internal battery voltage drops or the battery is not connected. Replace the
Loop Control Unit within five days of the ERC LED (red) starting to blink.
When the ERC LED starts to blink (red), ITEM095 of the System Common
block (Block Model 000) turns ON, and error log code 0330 is stored on the
Loop Control Unit.
Note 4
We recommend keeping a spare Loop Control Unit or battery available so
that repairs can be performed as quickly as possible in the event that a
malfunction occurs.
