The OFFand the EMERGENCY STOP buttons are connected in ries between terminals S11 and S12/S22 (Category 3) the auxiliary supply is connected to terminals A1(+) A2(–).The circuits to be tripped may be connected to terminals13-14, 23–24 and 33–34. If remote signalling is required then terminals 41-42 may be ud. When the EMERGENCY STOP button is activated power is removed from terminals S12/S22, relays K2, K3 are de-energid and contacts 13–14, 23–24 and 33–34 open.
The relay is equipped with three green LEDs. When illuminated they indicate the healthy condition of the auxiliary supply and circuits K2 – K3.
•Category 3 or 4 switch programmable,  SIL CL3•Contacts 3 N/O, 1 N/C (5  m gold plated)
•Removable terminal strips for fast replacement •Compact 45 mm wide ca
•Internal auxiliary power supply protection with automatic ret •
AC or 24V DC auxiliary power supply options
•Switch programmable single or dual channel operation,
auto or manual ret with short circuit/link monitoring of
E-stop and ret push-buttons.
Emergency stop relay BD 5935 complies fully with the requirements of the standard specifications referred to on page X. The unit is houd  in a compact 45 mm wide ca suitable for DIN rail mounting and is available in a wide range of auxiliary voltages. It differs from the  BN 5983described previously in that it employs fail-safe electronic circuitry for the lf checking and short circuit/link monitoring features  and has two switches under the front plate to enable the lection of:
Switch 1 -  Cross fault monitoring of E-Stop circuits (Category  4).Switch 2 -  Auto or manual ret
It is recommended that redundancy is carried through to the EMERGENCY STOP button by using a dual contact button as shown.If a single contact button is ud then terminals S12 and S22 should be bridged (Category 2 applications only).
To lect required function remove front cover with screwdriver (e diagram page X) and t switches to the desired position.
