10.8 Multi-CCU system	PC dedicated for Multi-CCU’s
Multi-CCU caters for situations where more than 240 contribution units are required. Multi-CCU		UPS (Uninterrupted Power Supply) recommended
systems are controlled from a separate, dedicated PC running OS.2 version 3.00 Warp operating		Multi-CCU Software LBB 3586 and OS.2
system, the Multi-CCU software (LBB 3586) and equipped with the LBB 3511/00 Network/Multi-
CCU card. All Multi-CCU units and the LBB 3511/00 are interconnected via a closed loop. FIG 10-20
shows a typical Multi-CCU configuration, for connection of up to a maximum of 16 LBB 3500/35
CCU’s.
