SH4 safety light curtains are composed of two parts: emitter and receiver.

In order to use the correct files to represent them, it's sufficient to refer to its model description (i.e. SH4-30-0600-S-8) 
and follow these instructions.

1. The SH4 model description of SH4 has this format:
 
	SH4-aa-xxxx-B/S/SM/A-y(-z)

	where:
		aa 		is the detection capability (14/30) expressed in mm for finger/hand models or the number of beams (2/3/4) for body models
		xxxx 		is the protected height expressed in mm
		B/S/SM/A/C 	is the functionality level (Base, Standard, Standard Muting, Advanced, Cascade)
		y 		is the polarity of the main connector on the receiver
		z (optional) 	is the polarity of the secondary connector on the receiver and when is present its value is 5

2. The files to be used for the receiver are:

	"SH4 - housing xxxx"  (or "SH4 - housing a-xxxx" if a=2/3/4 and then it's a body protection model) 
	"SH4 - smartplug y(-z)"

3. The files to be used for the transmitter are:

	"SH4 - housing xxxx" (or "SH4 - housing a-xxxx" if a=2/3/4 and then it's a body protection model) 
	"SH4 - smartplug 5" 	if "z" is not present
	"SH4 - smartplug 5-5" 	if "z" is present

Example A:

SH4-30-0600-S-8 will be represented by files:

	for the receiver: 	"SH4 - housing 0600" and "SH4 - smartplug 8"
	for the emitter: 	"SH4 - housing 0600" and "SH4 - smartplug 5"

Example B:

SH4-3-0800-A-12-5 will be represented by files:

	for the receiver:	"SH4 - housing 3-0800" and "SH4 - smartplug 12-5"
	for the emitter:	"SH4 - housing 3-0800" and "SH4 - smartplug 5-5"
