SL-VHS-IM-E

(1) Cable length

When using the unit connection cable, junction cable, and extension cable together, the sum of the

length for all type of cables must be 30 m or less. This limitation is applicable to each the transmitter

and receiver respectively. Since up to 3 SL-VHS units (230 beam axes) can be connected in series,

up to 2 sets of series connection cables are required. Two sets of the SL-VS10 (cable length: 10 m)

cables can be used. In this case, the sum of the length of all type of cables, including the series

connection cable, must be 50 m or less. This limitation is also applicable to each transmitter and

receiver respectively.

• Cables must be within the lengths specified. Failure to follow this specification may cause

improper operation of safety function, and may cause dangerous situation.

•

The series connection cable cannot be cut or extended. If the cable is cut or extended, safety

features may not operate properly. Do not allow this to happen as it is extremely dangerous.

(2) Minimum cable bending radius : 5 mm

(3) Identification of connector cables

Cables can be identified by the colors of their connectors and their cable insulation.

1. Cable Insulation colors

Cables for Transmitter : Cable insulation in grey

Cables for Receiver : Cable insulation in black

2. Connector colors

PNP output type cables : Black connectors

NPN output type cables : Grey connectors

Series connection cables : Black connectors

The PNP output type cable and the NPN output type cable cannot be used together at the same time.

Use only one of these types according to the operation condition.

Be sure to connect the unit connection cable for receiver to the SL-VHS receiver and the unit connec-

tion cable for transmitter to the SL-VHS transmitter.

■ Simple function type

■ Multi-function type

• The ON/OFF state of the state information output 1 indicates if the SL-VHS is in the lockout

condition.

• The ON/OFF state of the state information output 2 indicates if the SL-VHS is in the muting

condition.

• The pin assignment of the unit connection cable (for extension) is as follows.

The unit connection cable for transmitter (cable insulation is grey) must be connected to the transmitter as shown below. Sim-

ilarly, the unit connection cable for receiver (cable insulation is black) must be connected to the receiver as shown below.

Recommended tightening torque : 0.3 N·m

Minimum cable bending radius : 5 mm

Transmitter Receiver

• Do not remove the grey gasket installed on the connector. This gasket is necessary to ful-

fill the requirement of IP65.

•

Connect the unit connection cable to the connector receptacle on the lower part of the SL-VHS.

Removing the connector cover on the upper part of the SL-VHS and connecting the unit con-

nection cable may result in an SL-VHS failure.

2 One ferrite core must be put on the unit connection cable for the transmitter.

*1 The side where the connector cover has already been installed at shipment is the top side.

Beam center-line : An optical path joining the optical center of the emitting element on the transmit-

ter to the optical center of the corresponding receiving element on the receiver.

the SL-VHS must be installed so that the beam center-line mark on the transmit-

ter and that on the receiver face one another and are located at the same height.

Detection height : The height from the top beam center-line to the bottom beam center-line (length).

Protection height : An object approaching the detection zone from the top of the detection height is first

detected at point A, which is the distance of the detection capability from the top of the

detection height. The equivalent position on the bottom is called point B. The height from

the top edge of the specified detection capability that exists at point A to the bottom edge

of the specified detection capability that exists at point B is called a "protection height".

The following calculation formula can be defined:

Protection height = "Detection height" + 2 x "the specified detection capability"–"beam axis diameter".

Refer to the following diagram for an explanation of beam center-line, detection height and protection height.

Detection zone : The zone in which the specified detection capability can be detected. The

detection zone of the SL-VHS indicates a square area formed with the detection

height and the operating distance. When a part or whole of the specified detec-

tion capability is present in this area, the light of the SL-VHS is blocked, and then

the OSSD goes to OFF state.

Protection zone : The square area formed with the protection height and the operating distance,

which is broader than the detection zone. When a whole of the specified detec-

tion capability is present in this area, the light of the SL-VHS is blocked, and then

the OSSD goes to OFF state.
