Connecting Thermo-Maximal detectors in drive line
If the drive line is not correctly terminated with an end
line module for line monitoring or if the fi xed tempera-
ture heat detector is incorrectly connected, the yellow
fault indicator „
S
“ will signal a fault after a short whi-
le, unless line monitoring was disabled via the licensed
software.
If the line monitoring via the licensed software disabled,
no fault displayed .
Only connect when disconnected from the mains power
supply! Switch off power supply and secure against
reconnection!
!
Line length and cross-section A (drives) depend on the type of drive and
on the number of drives. Line length and cross-section can be determined
according to the following formula:
