Alternatively, the Software Assistant will guide you through the appropriate setting. If you use the SICK switching amplifier UE 402, you will find the functions under the same names, however to some extent in different places in the CDS Configuration dialog box.
C 4000 Standard/Advanced 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.
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.
C 4000 Standard/Advanced Protection of the environment 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.
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 Standard and C 4000 Advanced with the following entry on the type label in the field Operating Instructions: 8 009 855/OE59.
Please refer to pages 73ff. for the dimensional drawings. 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 height and the protective field width.
Fig. 4: Access protection using a safety light curtain C 4000 The safety light curtain C 4000 operates correctly as a protective device only if the follow- ing conditions are met: The control of the machine must be electrical. The dangerous state of the machine must be transferable at any time into a safe state.
Point not visible: The bottom edge of the numbers on the 7-segment display is pointing towards the LED display. Device symbol C 4000 Host (receiver) or C 4000 Host (sender), context menu Configura- tion draft, Edit, option 7-segment display of the related device.
Green System enabled (switching output on) Bypass active System error. Disconnect the supply voltage to the C 4000 for at least 3 seconds. If the problem persists, replace the unit. Poor alignment to sender. Please refer to chapter 7.2 “Aligning sender and receiver” on page 56.
This chapter describes the functions of the safety light curtain which are selectable via software C 4000. Some of the functions can be combined. An overview of the possible combinations and possible limitation is given in chapter 4.11 “Functions that cannot be combined”...

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.
C 4000 Standard/Advanced 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) …...
WARNING This is necessary so that the C 4000 can detect any fault that has occurred on the emergency stop button or door switch. The interval is to be defined to suit the specific case dependant on the application.
Page 54. Output signal (ADO) The C 4000 has a output signal (ADO) that can be configured. With the aid of the output signal, the safety light curtain can signal specific states. You can use this output for a relay or a PLC.
After activating the system, sender and receiver will briefly display the coding. Beam coding is only possible on systems with a maximum total of 405 beams. Device symbol C 4000 Host (receiver) or C 4000 Host (sender), context menu Configura- tion draft, Edit, file card General, option Beam coding.
5-19 m 4.6-17.4 m 4.2-16 m Device symbol C 4000 Host (receiver), context menu Configuration draft, Edit, file card Host or Guest, option Scanning range [m]. Notes If you are using the additional front screen (see page 88) available as an accessory, the overall scanning range will be reduced by 8 %.
The blanking function is only available on the C 4000 Advanced. Note The C 4000 Advanced offers various ways of blanking the protective field. In this way in many applications a higher level of safety and availability can be assured than would be possible without the usage of the blanking function.
Page 26
Also pay attention to the warnings in the related chapter. Properties of blanked areas The C 4000 Advanced is capable of blanking a total of four areas simultaneously. Fixed and floating blanking can be mixed. A minimum of one beam spacing must exist between two blanked areas. The CDS (Con- figuration &...
Fig. 11: Schematic layout of the fixed blanking The light curtain C 4000 Advanced is capable of fixed-blanking one or several adjacent beams, e.g. to allow continued operation in spite of an obstruction such as a table placed permanently in the light path.

Fig. 14: Schematic layout of the floating blanking The safety light curtain C 4000 Advanced is capable of blanking an area of two or more adjacent beams ( ). In contrast to fixed blanking, the blanked area is allowed to move ( ) without the light curtain changing to red.
To be able to use the teach-in function, the application must meet the following require- ments: A reset button is connected to the C 4000 Advanced and is correctly configured (see chapter 6.5 “Reset button” on page 51). A teach-in key-operated switch is connected to the C 4000 Advanced (see chapter 6.6 “Teach-in key-operated switch”...
Page 33
Chapter 4 C 4000 Standard/Advanced As an option you can connect a switch for deactivating blanking to the C 4000 Advanced (see section 6.6 “Teach-in key-operated switch” on page 52). You have already configured the number and type of blanked areas as well as the tole- rances with the aid of the CDS.
— Notes The reduced resolution function can only be used with the C 4000 Advanced with a phy- sical resolution of 14 mm and 20 mm. The first beam of the light curtain (close to the 7-segment display) must not be inter- rupted.
4.10 Sender test The C 4000 sender has a test input on pin 3 for checking the sender and the related re- ceiver. During the test, the sender no longer emits light beams. Thus, it simulates — for the receiver — an interruption of the protective field.
(The stopping/run-down time is shown in the machine documentation or must be determined by taking a measurement.) response time of the entire protective device, e.g. C 4000 consisting of host and guest (response times, see chapter “Response time” on page 69)
HIGH DC (at potential), when the light beams are interrupted or there is a device fault the outputs are LOW DC. The safety light curtain C 4000 meets the interference suppression requirements (EMC) for industrial use (interference suppression class A). When used in residential areas it can cause interference.
(see chapter 12.6 “Accessories” on page 89). If you do not use either a SICK switching amplifier or a SICK bus node, to improve the EMC behaviour we recommend, especially on cascaded systems, the termination of the...
For teach-in a reset button must be connected to the C 4000 (see chapter 6.5 “Reset button” on page 51). If you connect a teach-in key-operated switch to the C 4000, then you can no longer use the emergency stop or bypass functions in the C 4000.
You can design the two-channel button as equivalent (N/C, N/C) or complementary (N/O, N/C). You must configure the C 4000 as appropriate with the aid of the CDS. If the configuration and the electrical connection do not match, the system locks completely (lock-out).
The key-operated switch for bypass must have volt-free contacts. When you connect the key-operated switch for bypass to the C 4000, you can only connect a teach-in key-operated switch directly to the UE 402. An emergency stop can then no longer be connected, as it requires the same connections.
The sender test is performed when 0 V is present at the test input (pin 3). To be able to use the sender test button, you must also configure the Sender test function with the aid of the CDS: Device symbol C 4000 Host (sender), context menu Configuration draft, Edit, option Enable sender test.
Commissioning Commissioning requires a thorough check by qualified personnel! Before you operate a system protected by the safety light curtain C 4000 for the first time, make sure that the system is first checked and approved by qualified personnel. Please WARNING read the notes in chapter “On safety”...
Notes automatically deactivates the alignment mode. If you wish to readjust the alignment later, switch the power supply of the C 4000 off and back on again. The host in a cascaded system remains on red until all guests have been correctly aligned.
Configuration Delivery status As delivered the C 4000 is configured ready for protective operation. The C 4000 Standard without extension connection is also available as an option with the pre-configurations C, D, E and F. You can change the pre-configuration at any time with the aid of the CDS.
C 4000 Standard/Advanced Care and maintenance The safety light curtain C 4000 is maintenance-free. The front screen of the safety light curtain C 4000 and any additional front screen(s) (see “Additional front screen (weld spark guard)” on page 88) should be cleaned at regular intervals and when dirty.
The 7-segment display on the safety light curtain then indicates To place the device back in operation: Rectify the cause of the fault as per Tab. 21. Switch the power supply for the C 4000 off and on again (e.g. by unplugging the system plug and reinserting it). 10.2...
