INSTRUCTION MANUAL

ZJ - 4017F

Introduction:

•

This instruction manual describes the minimum necessary operations and functions for the
optimum adjustment of machines by using the LE-40MTB tension controller in Sections 1
through 5 taking "One-reel unwinding powder" shown below as an example.
Before start setting any systems, thoroughly read these five sections first.

•

When mechanism other than "One-reel unwinding powder" is used, read Section 6 "Mech-

anism other than one-reel unwinding powder" for setting. For the basic items such as the
initialization, wiring as well as zero and span adjustment, read Sections 1 through 5.

•

When using functions other than the above, read Section 7 "Use of extensive functions"

and after.

•

Note that this instruction manual is applicable to

system ROM version 5.00 or later.
