The Model SS is an infrared safety light curtain that is designed to the IEC 61496 standard. When properly installed, it protects the machine operator by passing an invisible infrared light beam across an area to be guarded and examining whether or not the light beam(s) are blocked. If the light beam(s) are blocked, monitored solid state outputs will open, issuing a command to the machines normally closed (N.C.) circuit. The System is composed of a transmitting unit (EMITTER), and a receiving unit (RECEIVER). The entire system is control reliable Category 4 (per IEC 61496). A single fault anywhere within the Model SS will not prevent at least one of the solid state outputs from opening up, (allowing a  command) when either a beam is broken or an internal fault occurs.







Theory of operation.
The Model SS protects an area by projecting a curtain of infrared light. The infrared emitters and receivers face each other across the field to be protected. Each emitter/receiver pair is spaced along the length of the pylons at regular intervals from .5", up to 8" depending on the application. The smaller spacing are for finger guarding, the larger spacing are for body protection. The emitter/receiver pairs are scanned sequentially (one at a time) by a very short pulse of infrared light starting from bottom (cable end), and working up to the top, until every beam pair has been scanned. Two 16 bit computers in the emitter pylon and two 16 bit computers in the receiver pylon control the operation, as well as cross check each pylon.

The System.
The Model SS employs infrared technology in a small sealed NEMA 4 aluminum housing with an infrared passing (daylight filtering) acrylic lens. This system provides harmless invisible protection and an unobstructed view of the guarded area. There are two parts to the Model SS: An Emitter pylon and a Receiver pylon. The Emitter pylon has no outputs, but does contain a digital CAN data network to allow it to be linked to the Receiver pylon (although not required for operation). The Receiver pylon contains the digital CAN data network and two monitored solid state 24vdc outputs. Both pylons are synchronized to each other either via the CAN data network or electronically.

System Safety.
The Model SS incorporates redundant, and diverse technology that provides a backup for every system that could cause an unsafe condition.

External Device Monitoring (EDM).
A method in which the Model SS Category 4 safety light curtain logic monitors the state of various external control devices. The control devices are external and not part of the Model SS light curtain pylons. A lockout or stop signal will result if an unsafe state is detected in an external device. The External Device Monitoring (EDM) is an optional function of the Model SS safety light curtain for monitoring the status of external devices such as gate and door switches, safety switches or the main control element of the drive (MPCE). Solid state outputs are turned on separately to be checked and assure neither output has been shorted, before fully turning on.

Design Criteria.
Designed to meet IEC 61496-1 & 2, UL 1998, UL subject 491, OSHA, ANSI, CSA, ANSI-RIA R15.06-1999

Microprocessor redundancy for both Emitter and Receiver pylons

Redundant, monitored, 24vdc solid state outputs (PNP)

Watchdogs on CPU’s and outputs prevent unintentional output during lockups.
