System description
3.1
Features
The electro-sensitive safety sensor T4000 Multi
comprises the following components:
coded actuators,
sensors,
a safety evaluation device for connecting up to
two (T4000-1RCA02) or four (T4000-1RCA04)
sensors.
3.1.1 Actuators
The actuator is mounted to the moving part of the
protective device. Each actuator has its own indi-
vidual electronic coding and is therefore uniquely
identifiable for the corresponding safety system.
The coding cannot be changed.
3.1.2 Sensor
The sensor is mounted to the fixed part of the pro-
tective device and connected to the safety evalua-
tion device with a two-wire screened cable.
The sensors can be supplied with permanently con-
nected cables or M8 plug connectors, see chapter 9
"Ordering information".
3.1.3 Safety evaluation device
The safety evaluation device uses redundant and
diverse safety circuits with two safety-relevant relay
outputs.
