Page 8: On Safety
C 4000 Entry/Exit On safety This chapter deals with your own safety and the safety of the equipment operators.  Please read this chapter carefully before working with the C 4000 or with the machine protected by the C 4000. Specialist personnel The safety light curtain C 4000 must be installed, commissioned and serviced only by specialist personnel.
Page 9: Correct Use
 The operating instructions must be made available to the operator of the machine where the safety light curtain C 4000 is fitted. The machine operator is to be instructed in the use of the device by specialist personnel and must be instructed to read the operating instructions.
Page 10: Environmental Protection
C 4000 Entry/Exit Environmental protection The safety light curtain C 4000 has been designed to minimise environmental impact. It uses only a minimum of power and natural resources. At work, always act in an environmentally responsible manner. For this reason please note the following information on disposal.
Page 11: Product Description
 Please read this chapter before mounting, installing and commissioning the device. Note The descriptions of functions in this chapter only apply to the safety light curtain C 4000 Entry/Exit with the following entry on the type label in the Operating Instructions field: 8 010 235.
Page 12: The Light Curtain Principle
C 4000 Entry/Exit 3.2.2 The light curtain principle The safety light curtain C 4000 consists of a sender and a receiver (Fig. 1). Between these two units is the protective field, defined as the protective field length and the protective field width.

Page 15: Configurable Functions
Always configure the application with restart interlock! Ensure that there is always a restart interlock. The C 4000 is unable to verify if the restart interlock of the machine is operable. If you deactivate both the internal and the machine’s WARNING restart interlock, the operators of the machine will be at an acute risk of injury.
Page 16: External Device Monitoring (Edm)
C 4000 Entry/Exit Reset If you want to activate the restart interlock on the C 4000 (internal) and also a restart inter- lock on the machine (external), then each restart interlock has its own button. When actuating the reset button for the internal restart interlock …...

Page 20: Self-Teach Dynamic Blanking
This must not exceed 2 m/s. The objects must enter the beam path of the C 4000 from the same direction. During this process the C 4000 first dynamically teaches itself the distance between the objects. The C 4000 monitors this distance until the objects leave the beam path.
