WATANABE ELECTRIC INDUSTRY WPMZ-1 Series User manual

MODEL WPMZ-1-□□□-□□-□□□ 1/12
IM-0880-02
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 “18. 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）

*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.
