ELDC Option
The ART2000 can be fitted with the ELDC Option, This option allows you to
disable the RCB from tripping the bay breaker during live shoots.
The ELDC system will power up in the “RCB enabled” mode indicated by
the Green switch being lit. After that each bay can be individually disabled
using the ELDC Master control key-switch and the Red disable switch.
The decision to disable the ELDC must be made by a competent body
capable of understanding the safety implications.
The switches will indicate the status of the ELDC system

ELDC detector active and enabled (Bay is Protected)
Red switch lit
ELDC detector active and disabled (Bay is unprotected)

not

whilst bay
breaker is on
ELDC detector
not

control fuse .
The ELDC system is not to be used in this
mode the bay is unprotected and unsafe
