6.2.2 DC supply
► The SELV criteria (safety extra-low voltage) must be met for the DC supply�
► The DC supply cable L+ (terminal 2) must be protected externally with a 315
mA T fuse (5 x 20 mm or similar)�
The DC supply terminals are directly connected to the sensor supply terminals�

Connection of the sensors
The connection of mechanical switch contacts is not recommended since
they tend to bounce and produce faulty pulses�
The terminals 5/6 can be used for the sensor supply or for the reset inputs (only
F���-x)�
6.3.2 Reset inputs (reset 1 and 2)
The start-up delay can be started or a saved error can be reset via the reset inputs
(terminals 17/18)�
► The in24 V DC voltage (terminal 5) or an ex24 V DC voltage is
connected with terminal 17 or 18 via a closing contact�
Reset for output 1 = terminal 17
Reset for output 2 = terminal 18
► If an external voltage is used, the negative reference point of this voltage must
be connected to terminal 1 of the monitor�
When the contact is opened (+24 V DC no longer applied), the start-up delay or
the memory reset starts�
