EF individual fuse protection KW

Each module is controlled separately. Acknowledgment signals are available for every module. The power output stage can in this way be blocked and unblocked independent of other modules.

To do so, lay the wiring as described below:

EF safety function control

24 VDC ext. control signal EF2	>>	X15 Pin 1 EF2
24 VDC ext. control signal EF	>>	X15 Pin 2 EF
0 VDC ext.	>>	X15 Pin 3 WEF

Acknowledgment power output stage blocked/enabled

24 VDC ext.	>>	X16 Pin 1 WQS (QES power supply)
X16 Pin 2	>>	Acknowledgment signal QES (QES = 1: Output stage safely blocked)

Acknowledgment of power output stage enable (QEF) of the input control signals EF AND/OR EF2

24 VDC ext.	>>	X16 Pin 3 WQF (QEF power supply)
X16A Pin 4	>>	Acknowledgment signal QEF (min. 1 EF(2) control signal is set)
