14.2 Dimensions, weight, response time
Dimensions, weight and response time are dependent on
• the resolution
• the length
• of the operating mode selected (SingleScan, DoubleScan, MaxiScan).

a) In the event of a failure (if the 0 V-cable is interrupted), each of the outputs behaves as a 120 k resistor to U
v
. A down-
stream safety PLC must not detect this as a logical “1”.
b) Note the additional restrictions due to cable length and load current.
Safety-related PNP transistor outputs (short-circuit
monitored, cross-circuit monitored)
Minimum Typical Maximum
The safety-related transistor outputs perform the spark extinction. With transistor outputs, it is
therefore neither necessary nor permitted to use the spark extinction circuits recommended by
contactor or valve manufacturers (RC elements, varistors or recovery diodes), since these con-
siderably extend the decay times of inductive switching elements.
The response times (see table 14.7) apply for operating modes 1, 2 and 3 (function group FG2).
In operating mode 3 (function group FG1, DoubleScan), the specified value doubles. In operating
modes 4 and 6 (MaxiScan), the response time always has a fixed value: 100 ms. The linkage of
a contact-based safety circuit or of electronic switching outputs in operating modes 1, 2 or 3 ex-
tends the response time by 2 ms.
