Test rod PLS
The test rod is used for testing the protection field.
MSD4 Vibration damper
Kit consists of: 8 vibration dampers 15 x 20 mm, 8 M5 cylinder head
screws with hexagon socket, 8 spring washers. Mounting using MS-1100.
The MSD4 vibration damper kit is recommend to be used for damping
vibrations and oscillations on the SLC440. For applications with higher
mechanical stresses, e.g. presses, punching machines, we recommend
the MSD4 kit. In this way, the availability of the SLC440 is increased.
Integrated status indication
The SLC440 series is also available with integrated status indication
(red/yellow/green) installed onto the receiver. (See ordering code)

¹) To IEC 61131-2
²) In case of failure, the leakage current at the most flows to the OSSD
cable. The downstream control element must recognise this state as
LOW. A safety PLC must detect this state.
³) The load inductivity generates an induced voltage during the switch-off,
which compromises the downstream components (spark quenching
element).
2.6 Response time (reaction time)
The response time depends on the hight of the protection field, the
resolution, the number of light beams and the beam coding A.
