Test rod
The test rod is an opaque, cylinder-shaped object used to check
the detection capability of the active opto-electronic protective
device. The diameter of the test rod is the same as the resolution
of the active opto-electronic protective device.
Universal I/O
Universal I/O can be configured as universal input or as universal
output.
Universal input
Depending on the device, a universal input can be used for reset‐
ting, external device monitoring (EDM), sleep mode, or restarting
the protective device, for example. If sleep mode is activated by a
universal input, the sleep mode must not be used for safety appli‐
cations. Certain universal inputs can also be used in pairs as a
static control input.
Universal output
A universal output outputs a signal depending on its configuration,
e.g. if the reset pushbutton needs to be pushed or if the optical
cover is contaminated. A universal output must not be used for
safety functions.
Warning field
The warning field monitors larger areas than the protective field.
Simple switching functions can be triggered with the warning field,
e.g. a warning light or an acoustic signal can be triggered if a per‐
son approaches, even before the person enters the protective
field.
The warning field must not be used for safety applications.
