Note (applications):
Safety sensor; Guard system
Note (Contact resistance):

Note (Delivery capacity):
Phased-out product
Note (General):
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
Note (ISD -Faults):
The following faults are registered by the safety monitoring modules and indicated by ISD.
Note (Wiring diagram):
The wiring diagram is shown with guard doors closed and in de-energised condition.; To secure a guard door up to PL d and Category 3; Monitoring 1 guard door(s), each with a magnetic safety sensor of the BNS range; The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix.; Expansion of enable delay time: The enable delay time can be increased from 0.1 s to 1 s by changing the position of a jumper link connection under the cover of the unit.; The feedback circuit monitors the position of the contactors K3 and K4.; Start push button: A start push button (NO) can optionally be connected into the feedback circuit. With the guard door closed, the enabling paths are then not closed until the start push button has been operated.; If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to ISO 13849-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off.; If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and A1.; Modification for 2 NC contacts: The safety monitoring module can be modified to monitor two NC contacts by bridging the terminals A1 and X2. In this configuration, the short-circuit detection becomes inoperative.
