Static control input A static control input is a dual-channel control input, which evalu‐
a
tes the status of every channel as the value 0 or 1. The signal
states of one or more static control inputs give a unique signal
pattern. This signal pattern activates a monitoring case.
Test rod The test rod is an opaque, cylinder-shaped object used to check
t
he 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
applications. 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.
S
imple switching functions can be triggered with the warning field,
e.g. a warning light or an acoustic signal can be triggered if a
person approaches, even before the person enters the protective
field.
The warning field must not be used for safety applications.
