} Switch­on (brake is ventilated):
– O1+/O1­ is switched on when there is a "1" signal (24 VDC) at Y10 and Y11.
– O2+/O2­ is switched on when there is a "1" signal (24 VDC) at Y20 and Y21.
– Partial operation is not time­monitored. An output will not switch until both the cor­
responding inputs are "1".
} Switch­off (brake is applied):
– O1+/O1­ is switched off safely when there is a "0" signal (0 VDC) at Y10 and/or
Y11.
– O2+/O2­ is switched off safely when there is a "0" signal (0 VDC) at Y20 and/or
Y21.
INFORMATION
Please note that when using fast shutdown, the inputs for slow shutdown
(S35 and S36) must have a "1" signal.

The power circuits are supplied via the terminals B1/B2 with the voltage U
B1B2
(voltage
range: rated voltage 24, 48 VDC).
INFORMATION
Max. current at the power circuits
It is essential to note that the effective current at terminals B1/B2 to supply
the power circuits must not exceed 10 A. The cables must be fitted with a
10 A fuse, characteristic B/C.
Both poles are switched (e.g. O1+, O1­).
