FEATURES
■ One-line connection system
See “MOUNTING SEVERAL AMPLIFIERS” on page 2.
A wire-saving sensor system can be established by combining other one-line connection amplifiers such as the FS-V10 Series or LV Series.
■ Easy connection with the European terminal
See “SENSOR HEAD CONNECTION” on page 1.
The sensor head is connected to the amplifier through the European terminal, allowing easy and quick connection.
■ Disconnection alarm indicator & output
See “PART NAMES AND FUNCTIONS” on page 1.
The alarm indicator and output turn on when the sensor head is disconnected, enabling quick discovery of abnormal condition. (The
ES-M2 features the indicator only.)
■ Mutual interference suppression function
See “MUTUAL INTERFERENCE SUPPRESSION” on page 2.
Mutual interference among several sensors that are used in close proximity can be suppressed by a simple operation.
ACCESSORIES

SENSOR HEAD CONNECTION
1. Modify the end of the sensor |
Shield wire |
|
Outer sheath |
||
cable as illustrated on the right. |
||
|
||
Be sure to tightly twist the shield |
|
|
wire and core wire separately. |
5 ±1 mm |
|
|
||
|
Core wire |
|
|
14 ±1 mm |
*When the outer sheath is stripped, the shield wire appears around the core wire. Separate the core wire and shield wire before modifying the cable.
2.Turn the terminal block tightening screws counterclockwise to loosen them.
3.Insert the sensor cable straight into the insertion port of the amplifier. Make sure that the core wire and shield wire are inserted into the correct ports and that the cable does not twist.
4.Turn the terminal block tightening screws clockwise to tighten them. Be sure to limit the tightening torque to
0.15 N•m.
5.Turn ON the amplifier and check that the disconnection alarm indicator remains OFF. If the indicator is ON, go back to step 1 and repeat the procedure again.

MOUNTING AMPLIFIER
■ Mounting/Detaching the amplifier to/from a DIN rail or the mounting bracket
Hook the claw located at the amplifier cable side onto the DIN rail, and then hook the front side claw to the rail while pressing the amplifier forward. To detach the amplifier, unhook the front claw by lifting the amplifier front side while pressing it forward.

Detaching |
■ Side mounting
Using the side holes of the supplied mounting bracket (ES-M1 only), fix the amplifier with screws.
