10.1 Input loop
An input loop increases the number of safety inputs.
• G9SR- AD□ - □ units use terminals T43 and T44 for the Input loop.
• G9SR- BC□ - □ units use terminals T32 (EDM input) and 14.
Connect the units according to following wiring schematic.
Caution
! Maximum cable length for each wire of the Input loop is 20
meters.
Caution
! Maximum cable impedance for the safety input circuit must be
less than 250 ohm.
Caution
! When the G9SR-BC is operating as a safety input in an input loop
configuration, the two output terminals "13" and “14" cannot be
used to drive additional loads.
Make sure there is no load connected to these two terminals when
the unit is in an input loop.
