WATANABE WPMZ-3 Series User manual

MODEL WPMZ-3-□□□-□□-□□□ 1/12
IM-0881-04
Thank you for purchasing the WPMZ graphical digital panel meter.
This manual is a quick instruction manual only for preparation,
connection and basic condition settings of the WPMZ. For the all
functions of the WPMZ, please refer to a detailed instruction
manual which can be downloaded from our homepage.
For models with RS communication functions, please refer to
"Modbus communication manual" or "RS-232C communication
manual" which also can be downloaded from our homepage.

Checks before suppling power, preparations, wiring
１. CHECKING THE PRODUCT
１－１. MODEL CODES
Please check that the product has been delivered matches the
model code ordered in reference to “19. SPECIFICATIONS”.
２. PRECAUTIONS FOR USE
２－１. ENVIRONMENTS AND CONDITIONS OF USE
Please do not use the product under the following circumstances.
It might cause malfunctions and shortening the life of the
product.
1）Ambient temperature of out of -5 to 50°C
2）Ambient humidity of out of 35 to 85%, or freezing
condensing
3）Excessive dust or metal particles
(Storing in a dust-proof chassis and a countermeasure
against heat dissipation are required.)
4）Environment of corrosive gas, salty air or oily smoke
5）Environment of much vibration or impact
6）Environment of rain or water drops (except the front
panel)
7）Environment of strong electromagnetic field or much
exogenous noises.
２－２. INSTALLATION AND CONNECTION
1）Please read this manual before the installation and the
connection of wires. And they should be performed by a
person having a specialized technique. In addition, the
insulation class of the WPMZ is as shown by the figure
below. Please confirm that the insulation class satisfies a
use condition prior to the installation.

2）Do not wire the power supply line, input signal lines and
output signal lines near noise sources or relay drive lines.
3）Bundling or containing in a same duct with lines including
noises might cause malfunctions.
4）The WPMZ becomes available functionally right after
power activation, but requires 30 minutes' warming to
satisfy all performance requirements.
Note: The inputs “A channel” and “B channel”may be
abbreviated to “Ach”and “Bch”in this manual.
２－３. CHECKING BEFORE USE
Install the WPMZ under the environments and conditions of use
which meet requirements.
If you find any damage to the product or any problem, please
contact to your dealer or our company directly.
３. HOW TO INSTALL (PANEL CUT DIMENTIONS)
To install the WPMZ, panel cut dimensions are as shown by the
figure below.
４. CONNECTING TERMINALS
４－１. BACK VIEW
４－２. WIRING TO SCREWLESS TERMINALS
Pushing the wire release button with a flat-blade screwdriver,
insert the wire to the wire insert hole deeply and then release
the button.
(Suitable tool for pushing buttons ：flat-blade screwdriver blade
width 2.5mm)

１４－２. PERFORMING SHORTCUTS
A shortcut function is performed by holding down the arrow key
which an external control function is registered for 1 second.
An active function becomes inactive by holding down the arrow
key which the function is registered for 1 second.
１５. MEASURE MODE
Select measure mode (Setting)→4.System→MeasureMode

１５－２. Multi hold
In the multi hold mode, measurements are divided into four
sections of section 1 to section 4, arbitrary hold settings are set
to each section, and comparison output is performed by hold
value in each section and comparison judgment value set for
each section, respectively.

*It is possible to measure up to ± 10% FS range on each range. (Limited
with ± 10% FS by internal processing. )
In the bipolar input setting, the full scale is set to be ± separately, and
for ± 10 V input, for example, limit processing is performed up to ± 11 V.
(20 V is not treated as FS.)
Also in the accuracy of ± 10 V input, it is prescribed as one side FS
handling and accuracy is calculated as 5 mV (0.05%) ± 1 digit.
