Switching current

The test input has a pull-up resistor to activate the sender (sender on) even when not connected. Therefore, an active-switched LOW signal is required to activate the

cyclic test with test gap (sender off).

Task

Integration of three L2000 (L28) family single-beam photoelectric safety switches in a UE410-8DI input expansion unit.

Function

The sensors switch when the light beam is clear. When sensor 1 and sensor 2 switch, the input condition for input A is met. If sen-

sor 3 has switched, the input condition for input B is met. If a light beam is interrupted, the related input condition (input A or input

B) shuts down the UE410-8DI.

Possible faults

A UE410-8DI has two test pulse generators. This means that short-circuits between odd (X1) and evenly (X2) numbered outputs will

be detected. Short-circuits between two odd (i.e., X1 and X3) or two evenly (i.e., X2 and X4) numbered outputs will not be detected.

In this case, short-circuits between X1 and X4 and X1 and X6 are detected, but short-circuits between X4 and X6 are not detected.

Comments

Take note of the operating instructions for the integrated devices.

The safety-related parameters (safety integrity level and response time) are dependent on the types used.
