System Overview and Scope of Applications General The COMPACT safety light curtains and light grids are active optoelectronic protection devices (AOPD) of the type 4 according to IEC 61496-1, -2 and EN 61496-1, -2. A two-dimensional protective field of infrared radiation is generated between transmitter and receiver.

Equipment Variants and Scope of applications The COMPACT is available in different models in order to provide an optimum price/performance ratio for differing applications. All models have one thing in common: the same engineering! COMPACT light curtains of series C30 and C14 for hand and finger protection at danger points Resolution: 14 mm (finger) and 30 mm (hand)
Deflection Mirrors A hazard location or a danger area can be guarded on more than one front by employing deflection mirrors. The maximum possible width of the protection zone is reduced for each mirror accordingly as shown in the following table. The use of more than two mirrors is not to be recommended because of the difficulties associated in the alignment.
Care is exercised in accordance with recognised codes of engineering practice in the development and production of Leuze lumiflex products. The protection function of the equipment can however be impaired if the units are not used in accordance with their intended application or are not used properly.

connecting caps control electronic IR transmitter module control and evaluation electronic IR receiver module aluminium profile Fig. 5 COMPACT System design Operating Mode The COMPACT works in the operating mode „Protection operating mode without restart disable“. Reception of all light planes switches the output voltage at the OSSD’s to +24 V. Interruption of one or more light planes shuts off the output voltage at the OSSD’s within the response time for the sys- tem.
Cascading COMPACT basic and follower equipment can be connected in succession in order to realise linked protection zones. Units of different resolution can thereby be combined with up to 240 planes of light (e.g. a basic unit 1650 mm with 14 mm resolution as finger protection and a follower unit with 450 mm and 50 mm resolution as step-over protection), see Table 2, Page 78.
Selectable System Functions The COMPACT is equipped with functions for the prevention of mutual interference and for an increased suppression of interference for operation in environments where there are sources of extreme infrared pulses, such as welding arcs. These functions are optional and can be activated by means of DIP switches. The switches are mounted on the circuit boards in the plug-in terminal caps.
3.5.1 Different Transmission Channels to Prevent Mutual Interference Two differing transmission channels can be set by means of the DIP switch S2 in order to prevent functional disturbance from mutual interference by two neighboring units. The selected transmission channel 1 or 2 is indicated in the transmitter and receiver displays. Fig.
3.5.4 Test Input The COMPACT is equipped as AOPD Type 4 with a permanent self-monitoring function, which automatically detects faults in the system as well as cross-circuits and short-circuits to the output cables. An external signal is not required for this. In order to test connected circuits for follower pro- tection devices, an external control (e.g.
Diagnostic Function Transmitter and receiver are equipped with extensive self-diagnostic functions. An „F“ is indicated in the 7-segment display for a discrepant unit in the event of a component failure. This enables the quick on-site identification of defective components (refer to Chapter 6.2). A PC can be connected to the serial RS-485 interface for visualizing the light axes during alignment or for locating problems in the workshop.
Installation General Installation Procedures Attention shall be paid to the general notes on safety given in Chapter 2. Principally, all units shall be installed such that the hazard location can be reached only by the interruption of at least one plane of light and sufficient clearance is maintained between hazard location and the protection zone.

Mounting Procedures for COMPACT Light Curtains (Series C14 and C30) With the COMPACT light curtains for finger and hand protection, it shall be observed that access to the protection zone is not possible from above, below or around, as well as from stepping over the curtain, by the incorporation of additional mechanical safeguards or by cascading the COMPACT units.
Mounting Procedures for COMPACT Light Grids for Vertical Access Protec- tion (Series C300/4, C400/3, C500/2, C301/4, C401/3 and C501/2) The installation of COMPACT light grids shall ensure that hazard locations cannot be accessory by crawling under, between, reaching over the planes of light, or by reaching through the planes of light.
Installation Specifications for COMPACT Light Grids for Danger Area Safe- guard, Horizontal Arrangement (Series C50 and C90) When light grids, horizontal arrangement are being mounted to safeguard danger areas, make sure that the height of the sensing field does not exceed 1000 mm above the ground. If H exceeds 300 mm (200 mm if children are present), an undetected approach underneath the sensing field is pos- sible.
Mechanical Installation The units are mounted using M6 T-slot nuts with an M6 thread, which is inserted from the side into the longitudinal grooves. The M6 T-slot nuts can be freely adjusted and allow the unit to be aligned along the longitudinal axis. These nuts are fitted with a retainer spring to prevent the elements from accidentally slipping when the screws are being tightened and in order to make the mounting easier.
Electrical Installation Installation Regulations Attention shall be paid to the general notes of safety given in Chapter 2. The electrical installation shall be performed by experienced and qualified personnel. The OSSD outputs of the COMPACT are principally to be connected as two-channel outputs to the safety engineering section of the machinery controls.
Power Supply The power supply to transmitter and receiver shall be 24 V DC ± 20 %. The maximum power con- sumption of COMPACT equipment including 2 x 0.3 A on-load current, amounts to 0.9 A. The power supply shall meet the requirements of prEN 60204 and exhibit a safe mains separation as well as bridging short-term mains failures of up 20 ms.
