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 proce-
dure. (
➮ 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. ( ➮ p.95)
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.)
Adjust the distance between the sensor head and target so that the distance
between them is about half the measuring distance when the stripper is in the
bottom dead center position. The controller’s display shows a value close to the
half scale.
Target
Sensor head
In the case of the EX-305V,
the value is close to “0.5”.
Stripper or upper die
Half the measuring range
of the sensor to be used.
