12 E3C011 Battery charging module (supersedes E3C010)
12.1 Overview
z For the charging and monitoring of the 24 V emergency power battery (the same
function unit is contained in the E3X10. master module
z I-Bus module with processor
z Designed for the AC/DC converter B2F020
z Temperature compensation via external temperature sensor
z Choice of functions (via maintenance PC)
– emergency power available yes/no yes *
– battery available yes/no yes *
– charging yes/no yes *
– presence monitoring yes/no yes *
– symmetry monitoring yes/no yes *
– automatic battery load test yes/no yes *
– Fault signal delay upon mains failure 1 …30 min.
* factory setting is possibly
overwritten if E3C011 is
run via I-Bus (via Al-
goWorks)
z
Card format 100 mm x 200 mm

at a great distance
12.3 Key data
Input voltage 29.6 VDC ±2 % (B2F020)
Battery 2 x 12 V / 6...42 Ah, lead battery
(full battery recharging up to 80 % within 24 h)
Charging characteristics Can be adjusted to 16 makes of battery using programming switch ”S2”
Charging current max: 1.7 A (current limitation)
Battery monitoring Battery presence test every 55 sec
Symmetry monitoring Asymmetry > 1 V = Fault
Battery test automatic battery load test
(3 A for 10 sec once every 23 h),
Can also be activated manually via AlgoPilot B3Q... control console
EMI-protected battery line no
Low discharge protection Battery operation switches off when voltage is ≤ 21.0 V
Quiescent current 20 mA when on emergency power operation
40 mA when on mains operation without battery charging
Terminal block X17 (20 terminals)
