Chapter 2 Quick Guide to Basic Mode Operation

2.1 Measurement Modes

The EX-V series provides the following four measurement modes: "Bottom-deadcenter mode", "Eccentricity/vibration mode", "Thickness/gap mode" (which are basic modes for quick operation), and "Manual mode" (which allows users to perform setting as desired). This section explains the major functions of each mode.

2.1.1 Bottom-dead-center mode

This mode is used to measure the displacement of the origin position of a machine with stroke movements such as a press. When the displacement of the bottom dead center or origin position is out of the preset tolerance range, the sensor outputs an Alarm signal.

Major applications

• Detecting the bottom dead center position of a press

• Detecting the bottom dead center position of a press-fit machine

• Detecting the bottom dead center position of a welding machine

• Pressure control for a injection molding machine

• Measuring the depth of the recess on a piston head

2.1.2 Eccentricity/vibration mode

This mode is used to measure the roller eccentricity or abnormal machine vibration. When the amplitude of the runout or vibration is larger than the preset tolerance limit value, the sensor outputs an Alarm signal.

Major applications

• Measuring roller eccentricity

• Measuring surface plate runout

• Detecting runout due to improper chucking

• Measuring drill bit eccentricity

2.2 Quick Guide to Basic Mode Operation

This section describes the major measurement modes and an easy setting method.

2.2.1 Setting the bottom-dead-center mode

The following example explains how to mount the EX-V series to a press.

The basic operation is the same when mounting the EX-V series to other devices. Be sure to adjust the output characteristics before performing the following procedure. (➮

Refer to page 9

1. Secure the sensor head to the lower die of the press.

• Referring to the figure below, prepare the sensor head mounting jig and a target.

• Refer to pages 7 and 8 for the position of the sensor head nut and the tightening torque.

Note: Be sure to use an IRON target with sufficient area for detection. (➮

Reference: When the comparator output is already connected to the emergency

stop or another input for the facility, short-circuit the OUTPUT DISABLE input (terminal 3) and grounding terminal (terminal 7) to disable the comparator output before making the adjustment. * After making the adjustment, be sure to disconnect these terminals to enable the

comparator output.

2. Adjust the distance between the sensor head and target.

Move the press an inch at a time and lower the stripper (or upper die) to the bottom dead center position. (Refer to the figure below.)
