■ SPR can be used partly for simple roller conveyor transport and partly for accumulation purposes. ■ SPR can be controlled by means of a SOCO Power Supply Box (PSB) and/or by means of a PLC control system. ■ SPR fits SOCO SYSTEM’s series of 48 mm roller conveyors mechanically.
2. Safety 2.1 Safety in general Our products conform to all relevant EC directives on safety and health. The products are manufactured with reference to EC harmonised standards. Some of our products require further safety guarding before use. This will appear from the EC declaration of components.
3. Survey 3.1 Survey of SPR Five wires are led out of the roller and joined in a 6-poled female socket. The illustrated socket is seen from the wire side. Colour Name Application Direction Description Brown Supply Supply To SPR 24 VDC Green Neutral...
4. Operation, application, and compatibility 4.1 Operation IMPORTANT: If the roller is started while laying loose or held in the hand, please note that the end part and not the metal roller will rotate. In this way, the cable from the roller will be damaged. When connecting voltage, the motor control system initialises.
4.3 Compatibility Old rollers with 5 wires Full compatibility. Old rollers with 2 wires If a start-up time of 1-2 seconds is acceptable, the old roller with 2 wires can be connected with the brown and green wires only. To avoid this start-up time, provide constant supply to the roller on the brown and green wires.
An SPR is typically used for accumulation conveyors where each roller can accumulate one item. This can be controlled either by a PLC system or by a SOCO power supply box. This section describes accumulation by means of a Power Supply Box, subsequently named PSB.
5.3 Pressure or zero pressure accumulation Pressure accumulation can be used when the following requirements can be met: ■ The lengths of the items are always identical. ■ The weights of the items exceed 5 kg. ■ The items can withstand collision with other items. ■...
SPR9 SPR8 SPR7 SPR6 SPR5 SPR4 SPR3 SPR2 SPR1 PSB2 PSB1 The illustration above shows an accumulation section with 9 rollers, 9 photocells, and 2 power supply boxes. Items are conveyed from left to right and accumulated by means of zero pressure accumulation. Signal transfer between PSBs takes place by means of a cable with 2 conductors.
The Status signal from SPR2 is sent to the Accu wire of SPR3. This continues further backwards in the system. Onward transport Outlet starts when the transmitter is switched off/opened (this means when the front carton is removed or product stop is lowered). SPR1 starts after 1.5 seconds. When SPR1 has accelerated (after yet another 1.5 seconds) it switches off its Status signal.

In connection with further conveyance of items: - Connect an external contact signal between terminals 13 and 14 on KL1 in PSB1. - When the contact signal is opened SPR1 starts and item no. 1 is conveyed onward. - When S1 is no longer activated, SPR2 starts. In this way, item no. 2 is conveyed to S1. - When the external contact signal is closed again, SPR1 stops when S1 is activated again.
If so, the problem is due to the control of the Status signal to the roller. If the roller does not function and is to be returned to SOCO SYSTEM, please include the following pieces of information with the roller: ■...
