The
safety light curtains TLVT are electrosensitive protective devices
(EPSE) and are characterized by compliance with safety category 2, IEC
61496 parts 1 + 2 i.e. EN 61496 parts 1 + 2. |
|
- integrated control-unit with contactor control and restart activatable by DIP switches activatable
- contactor/valves directly connectablly, switching capacity 0,5A/24V
- smallest safety distances by short response times 6 ms to 25 ms, depending of the protection high
- smallest obstacle recognition of 14mm up to 7m range
- hand protection up to detection range of 24 m, recognition of smallest obstacles(30 mm)
- protection heights of 100mm to 1900mm
- microprocessor monitoring of the safety functions
- self-monitoring semiconductor outputs with line interruption monitoring, short-circuit- and side current passages check.
- built in selfdiagnostic with error display
- minimum safety distance due to short response times, between 5 ms and 25 ms, depending on constructional lenght
- protective system IP65

The
safety light curtains TLVT consist of the two components: transmitter
and receiver. The distance between both components and the overall
height result in those protection width and - height.
By the modular construction protection heights of 100mm to 1900mm are realizable. Special sizes are also available.
Transmitter
and receivers operate synchronously, i.e. at the same point in time
only a light beam and a reception item are active. The synchronisation
is made by the first light beam and the first reception item. Between
transmitter and receivers therefore no electrical connection is
necessary.
The transmitter creates infrared light
beams, which are switched on and off rapidly successively. The parallel
light beams with a distance from 7,5mm are controlled by two a chip
micro controllers. A resolution of 14mm is realised by the beam
distance.
Synchronously to the light beams of the
transmitter in the receiver all reception items are analysed by two a
chip micro controllers. If an object is in the protection field, i.e.
it is darkened at least one of the beams, the two outputs of the
receiver interrupt the dangerous movement of the machine, or prevent a
start. A renewed start of the machine is in the operating mode with
restart only possible by pressing the start push-button during a free
protection field.
Several LED at the receiver display
thereby the respective operating condition. The system detects an
internal or external error the machine is immediately switched off and
the LED in the transmitter or in the receiver shows by flashing the
error status. |

Integrated connector plug in connector cover |
| |
The
TLVT construction series is supplied with PG threaded joints as
standart. Various conventional connector plugs can also be obtained as
optional accessories. The electric connection is implemented via
terminal screws in the connector cover. The cover can be removed once
the 4 screws have been loosened.
The transmitter
is connected via a 3-core cable, the receiver is connected via a 5 to
7-coire cable(according to the mode of operation) |

DIP-position
With contactor check |
The operating mode with contactor control serves for monitoring the triggered follow-up contactors.
After each interruption of the optical path and before each release of
the switching outputs the follow-up contaction are checked whether they
dropped. If the contactors don´t dropped with in 300ms the light
curtain output contacts go into lock status. |

IIf
the operating mode with restart control is adjusted, a push-button must
be connected for the start release of the working movement.
With a
free protection field the yellow LED lights up. After actuating the
start push-button the two outputs of the TLVT are activ. |

Antivalen outputs |
During the operational mode equivalent outputs both PNP outputs and provide short-circuit- and side-current passages monitoring.
With
free optical path both outputs are high(+24V). During the operational
mode antivalent outputs, output No. 1 is high (+24V) and output No. 2
low (0V), with free optical path. |
