Be sure not to place power wires such as the input point signal wire and the
output point wire, or the power supply, at the same conduit during wiring.

Points of Attention
Environment
1. DO NOT install the PLC in a dusty, smoky, or corrosive atmosphere.
2. DO NOT install the PLC in an environment with high temperature or high condensation.
3. DO NOT install the PLC in an environment with immediate vibration and shock.
Construction
1. Any accident the drop of conductive debris into the PLC during screwing and wiring has to be avoided.
2. Allow a minimum space of 50mm between PLC and other control components, and keep PLC away from
the high-voltage lines or any power equipment.
4.3 Wiring and Specifications of the Power Terminals
This PLC model uses DC input power. Therefore, make sure that PLC is connected to terminals 24VDC and
0V (power range 20.4VDC~28.8VDC) when the power is ON. PLC will stop the operation and output will be
OFF whenever the power input is lower than 20.4VDC. Consequently, the ERROR LED will blink swiftly.

Safety Guidelines
Due to the PLC is used to control numerous devices, a motion in one device could affect that of other devices.
Hence, the breakdown in one device would consequently a detriment to the whole auto control system, and
danger or damage will be significantly. Listed below is the recommended wiring for the power input:

Overload Capacity of the Output Terminal
Every output contact possesses the overload capacity that is twice the rated current within 5 minutes, and as
for the common contact, the overload capacity is 1.5 times the rated current within 2 minutes. And if the
O

range is exceeded, it might result in the contact's malfunctioning, or even cause internal wire burnt.
There are two types of output modules for the DVP-S Series PLC: relay or transistor. Refer to Functions &
Specifications for relevant electric specifications.

RELAY OUTPUT
When actual wiring is conducted at the output terminal, pay special attention to the wiring at the common
end. Take DVP14SS11R2 as an example, the output terminal Y0 utilizes the common end C0, and Y2 uses
C1, whereas Y2~Y5 use C2, as shown in Fig. C.

Power Indication
1. At the front of the MPU or the expansion unit, there is a "POWER" LED. When the MPU is powered ON, the
LED (in green) will be ON. If the indicator is not on when the MPU is powered up, it means there is problem
that DC power supplies to PLC. Thus, it is important to check whether the wiring of +24V and 0V are properly
conducted. If ERROR LED is blinking swiftly, it means +24VDC does not supply enough power to PLC.
2. If the other indicator, "L. V", that locates at the front of the extension unit is on, it means that the input power
current outflow S/S
voltage to the extension unit is insufficient, and the output from the extension unit should be prohibited.

Preparation
1. Make sure that the power wiring and the I/O wiring are both conducted properly before the power ON. Please
ensure NOT supply AC110V or AC220V to the I/O terminals, or the wiring might be short circuit which would
damage the PLC directly.
2. After using the peripheral devices to write the program into the MPU and that the ERROR LED of the MPU is
S/S
not on, it means that the program in use is legitimate, and it is now waiting for the user to give the RUN
Sourcing
command.
3. Use HPP to execute the forced On/Off test of the output contact.
Operation & Test
Wiring Circuit
1. If the ERROR LED of the MPU is not blinking, use the peripheral device to give the RUN command, and the
RUN indicator will then be on.
2. HPP could be utilized to monitor the settings and the registered values of the timer, the counter and the data
register during operation. Also it is used to force the I/O contacts to conduct the On/Off motion. If the ERROR
LED is on (but not blinking), it means that the setting of the user's program has exceeded the preset time-out
limit. At this case, please turn the PLC RUN/STOP switch to STOP, and find out the address of the time-out
program by special data register D1008. "WDT" instruction can be used to solve the problem.

6.1 Judge the Error through the Indicator at the Front Panel

on. If the indicator is not on when the MPU is powered up and with the input power being normal, it is an
indication that the PLC is out of order. Please have this machine replaced or have it repaired at a dealer near
you.
Fig.

"RUN" LED
Identify the status of the PLC. When the PLC is in operation, this light will be on, and users could thus use
HPP or the ladder diagram to edit program and give commands to make the PLC "RUN" or "STOP".
"ERROR" LED
1.
If illegitimate program is input to the MPU, or that the commands and devices of the program exceed the
allowable range, the indicator will thus be blinking. In this case, the user should inquire about the error
code from the special data register D1004 in the MPU and look it up in the Error Code Table. After the
error is found and the program is revised, send the revised version to the MPU.
2.
If the PLC is unable to perform function, and the LED is blinking swiftly, it indicates that 24VDC power
does not supply sufficient power. Please check whether the power supply of 24VDC is normal or not.
3.
When the ERROR LED is on (not blinking), it is an indication that the execution time of the program
circuit has exceeded the preset time-out limit (setting of D1000). To check the program circuit or use the
WDT command to improve the error status. Once program modification is completed, user can
re-download the program of PLC and the ERROR LED will be off. If the ERROR LED is still keep on,
please turn off the power and check if there's any noise or any conductive invader inside the PLC.
"Input" LED
The On/Off signals of the input point could be displayed through the "Input" LED, or monitor the status of the
input point through the device HPP monitoring function. Once the motion of the input point is valid, the LED is on.
Therefore, if errors are detected via using HPP, the LED and the input signal circuits then are used to check
whether the status is normal. Especially when the electronic switch of great electric leakage is utilized, the input
point is usually witnessed with unexpected motions.
"Output" LED
The "Output" LED is designed mainly for display the On/Off status of the output signals. When the "Output" LED
is On or Off and that the loading is of an opposite motion, the following conditions should be attended to:
1. The output contact might be melted down and blocked up due to overload or load in short-circuit, defect
happened consequently under this situation.
output current greater than
2. If the output contact is function as undesired, be sure to check the output wiring circuit and whether the
screw is tightened or not.

6.3 Periodic Inspection
Since the DVP series PLC does not utilize disposable components, there is thus no need to replace most of the
components. However, if the output relay turns on/off frequently, or drive the large load current too often, life of
the output contact will thus be decreased. Under a condition like this, periodic inspection is then needed to
ensure if the contact is of the "Permanently Open" status or of the short-circuit status. Moreover, the following
precautions should be noted:
1. Do not mount the DVP under direct sunlight or near any heat-radiation objects.
2. Do not install the DVP-PLC in places subject to high temperature, high humidity, excessive vibration,
corrosive gasses, liquids, airborne dust and metallic particles.
3. Check periodically whether the wiring and terminals are tightened and conducted properly.
