SH4 safety light curtains are composed of two parts: emitter and receiver or active and passive units, depending on the model.

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, or more easily refer to the excel file "SH4 - 3D Models Build Up Legend.xls" in which are indicated which files are needed for any model.

1. The SH4 model description of SH4 has the following format:
 
        SH4-aa-xxxx-B/S/SM/A(-AP)-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 number of poles of the main connector on the receiver
		z (optional) 	is the number of poles of the secondary connector on the receiver. When it is present its value is 5
		AP (optional)	indicates the Active-Passive functional mode. 
				If AP is in the code, the pair is composed of one active unit (transceiver) and one passive unit
				If AP is not in the code, the pair is composed of one receiver unit (RX) and one transmitter unit (TX)

If the pair is composed of Receiver and Transmitter Units:

	1. The files to be combined for the complete 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)"

	2. The files to be combined for the complete 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

If the pair is composed of Active and Passive Units:

	1. The files to be combined for the complete active unit are:

	"SH4 - housing a-xxxx active" 
	"SH4 - smartplug y(-z)"

	2. The file to be used for the passive unit is:

	"SH4 - housing a-xxxx passive"




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"
