Installation and Connection
This chapter describes precautions when installing and connecting the SK Series.
Mounting and Wiring the Sensor Amplifier
Mounting the Sensor Amplifier
„ SK-1000
1
Align the tab at the bottom of the amplifier body with the DIN rail.
While pushing the amplifier in the direction of the arrow (1), push
down in the direction of the arrow (2).
2
To dismount the sensor, raise the main body in the direction of the
arrow (3) while pushing the main body in the direction of the arrow
(1).
„ Expansion unit (SK-1050)
Incorporate multiple units into one system by connecting expansion units to the
main unit.
Up to 7 expansion units can be connected to one main unit.
Point • When connecting the expansion units, make sure to initialize the
connected expansion units and set the output polarity.
(1)Turning on the amplifier for the first time after connecting the
sensor head
"Operation When the Power is Turned on for the First Time"
(page 7)
(2)Performing the initial reset
"Initial Reset (Initialize)" (page 8)
• Expansion units with different setting of output polarity (such as
an NPN output expansion unit and a PNP output main unit)
cannot be connected together.
1
Remove the expansion protective cover from the SK-1000 (main unit)
2
Install the amplifiers (expansion units) on the DIN rail.
For details on how to install the unit, see the above explanation for the SK-1000.
3
Push the expansion unit into the main unit connector until a clicking
sound can be heard.
The expansion unit installed next to the main unit is referred to as expansion
unit 1. Subsequent expansion units are referred to as expansion unit 2,
expansion unit 3, etc.
NOTICE
• Always mount expansion units onto a DIN rail.
• When connecting multiple amplifiers (expansion units), first
check to make sure that the power is turned OFF to all of the
main and expansion units. Connecting the units with the power
turned ON may cause damage to the units.
• Position the amplifiers (expansion units) as close as possible to
the main unit. Improper connections may damage the
equipment.
