I wonder if the correct (factory pre-set) "working" mode has been selected for your application.
Here's a ES link with some info on this from (Elcon customer rep?) "Nancy".

Note the post regarding the factory pre-set "working" modes:
Working mode 1 = CAN (Controller Area Network) module control option 1. This is a working mode when use (using) BMS which has CAN communication function. Please connect CAN bus through plugging in CAN module.
We set CAN ID and CAN module type at factory at customer's request. Specified and CAN communication protocol supported is set up before delivery.
2. Mini BMS or Battery protector option. This is a working mode when use battery protector or BMS(no CAN communication function). Charging can be switched on or off the charging through charging enable control wire like charging process below...
I'm not sure how (or if) you can check the selected "working" mode. However, maybe Elcon or your supplier can answer this question for you. I am, however, thinking that "working" mode #2 might be the correct selection for your application.
I'm also wondering if the correct "Charging Curve" has been selected. There are, according to manual (link), 10 different "curves" available (please see the manual for the directions on how to check and/or select these charging curves).
