SG 1

SpaceGuard™  

Description
The SG 1 system consists of a self-contained transmitter detector, SGT and a receiver detector, SGR which are available in sturdy slimline (10x28 mm) and leading edge (37.5x13 mm) aluminium profiles. The series is available as a 20 channel system which generates 94 crossed infrared light beams, and as a 40 channel system which generates 194 crossed infrared light beams. All the models are available as a 4 wire, NPN or PNP transistor output, or 5 wire, solid state output with 12-36 V dc supply voltage.

The advanced feature, automatic signal tracking (AST), ensures that no on-site set-up or adjustments are required. The signal level of each channel is continuously adjusted automatically according to the operating conditions, compensating for misalignment and moderate contamination. The time-out function, which can be selected via wire connection, allows up to 4 non-adjacent channels to be ignored if permanently obstructed for 10 seconds or more. If a time-out channel resume operation, the time-out will automatically be cancelled. The test input in the SGT may be used for disabling or enabling the transmitter beams to imitating an obstruction for test purposes.

The transmitter and receiver are protected against reverse polarity of power supplies, test input and output signals. The output is protected against short circuit and inductive loads.

SG 11

SpaceGuard™  

Description
The complete SG 11 system consists of a transmitter detector, SGT, receiver detector, SGR, and controller, SGC. The detectors are available in sturdy slimline (10x28 mm) and leading edge (37.5x13 mm) aluminium profiles. The series offers a selection of detectors with 16 to 64 parallel light beams and 0.57 m to 2.10 m in length. All models are available with flexible and non-flexible cables, with plug connection to the SGC controller.

The controller offers a choice between automatic and manual sensitivity adjustment via an integral potentiometer located on the circuit board. Output can be selected from either a relay or an NPN transistor output, which can also be used as an output for alarm and/or time-out. Light or dark function, and long and short range are switch selectable. The time-out function is DIP switch selectable between 4 to 32 channels, which allows the channels to be ignored if permanently obstructed for a pre-set period of time, DIP switch selectable between 0.3 to 10.0 minutes.

The controller continuously monitors the transmitter and receiver detectors, and will automatically detect an electrical failure or loose connection. The output will then revert to safe position. The failure is indicated by the Failure and Alarm LEDs.
