Page 6: General Information
The instructions for use given herein are addressed to designers, manufacturers and persons in charge of the safety of systems to be equipped with the SG-BWS-T4. They are also addressed to the staff in charge of installing the SG-BWS-T4 to a machine, commissioning it or servicing it. -
Page 7: Product General Description
Fig. 1 SG-BWS-T4-MT Appearance and user interface SG-BWS-T4 safety system consists of a control unit enclosed in a plastic housing to be installed on OMEGA/DIN rail equipped with 16 screw clamps that can be connected up to 4 sets of photocells of the S5-ST, SL5-ST, S300 series. -
Page 8: Safety Sensors
S300-5-X-X-ST4: Type 4 safety photocell for long-distance applications. See section 10 “Order data” for further details about available photocell models. Using the above photocells independently from SG-BWS-T4 does not meet EN 61496-1 and CLC/TS 61496-2 requirements and is thus not allowed. -
Page 9: Main Functions Managed By The Control Unit
2.5. Typical Applications The SG-BWS-T4 system is typically used as a protection to the access to dangerous areas on machines or systems. The sensors are fixed and installed to the access area at the suitable safety distance from the nearest danger source and output a stop control to the machine or system, if the light beam is interrupted. - Page 10 Fig. 4 Doors control by means of safety photocelss Solution: SG-BWS-T4 is able to detect the door opening by using one or more photocells by intersecting the interrupted beams, guaranteeing the safety condition. Advantages: all the safety interlocks can be replaced on each door thanks to the use of photocells...

Page 11: Installation
INSTALLATION 3.1. Safety information For a correct and safe use of the SG-BWS-T4, the points considered in this section must be observed. The stopping system of the machine must be electrically controlled. This control system must be able to stop the dangerous movement of the machine within the total machine stopping time T as per par. -

Page 14: Minimum Distance From Reflecting Surfaces
SG-BWS-T4 3.5. Minimum distance from reflecting surfaces Reflecting surfaces placed near the light beams of the safety device (over, under or laterally) can cause passive reflections. These reflections can compromise the recognition of an object inside the controlled area. However, if the RX receiver detects a secondary beam (emitted again by the side-reflecting surface) the object might not be detected, even if the object interrupts the main beam. -
Page 15: Sensors Interference
When several safety devices must be installed in adjacent areas, interference between the emitter of one device and the receiver of the other must be avoided. SG-BWS-T4 monitors possible interference between photocells and locks out if any interference is detected. -
Page 16: Installing The Safety Control Unit
3.7. Installing the safety control unit The SG-BWS-T4 control unit is simply installed onto an OMEGA/DIN rail placed inside a control panel. Fig. 10 Safety Control Unit mounting The 4 4-pole connection terminals can be disconnected quite easily using a flat-blade screwdriver and can be connected by hand. - Page 17 SG-BWS-T4 Use of deviating mirrors The control of any dangerous area, with several but adjacent access sides, is possible using only one safety device and well-positioned deviating mirrors. The figure shows a possible solution to control three different access sides, using two mirrors placed at 45°...

Page 18: Electrical Connection
For SG-BWS-T4 to work as a safety device an external MPCE (Machine Primary Control Equipment) must be connected that controls main machine power supply. Fig. 12 shows the connection to 2 external safety relays that can be monitored by SG-BWS-T4 by means of the EDM connection. -

Page 24: Reset Mode And Connection Of The Start/Test/Reset Push-Button
SG-BWS-T4 4.8. Reset mode and connection of the Start/Test/Reset push-button The interruption of a beam due to an opaque object causes the opening of OSSD outputs and the stop of the safety control unit (SAFE condition, SAFE). ESPE standard operation can be reset (OSSD safety outputs closing, NORMAL OPERATION condition, NORMAL) in two different ways:... - Page 25 SG-BWS-T4 Test function The Test command temporarily disables beam emission in order to check switching to SAFE status. This function can be activated by opening (for at least 0.5 seconds) an NC outer contact (START/TEST/RESET push-button). The TEST signal is active low.
