6INSTALLATION & WIRING
6.1 PLC Mounting Arrangements and Wiring Notes
Installation of the DIN rail
The DVP-PLC can be secured to a cabinet by using the
DIN rail that is 35mm high with a depth of 7.5mm. When
mounting the PLC on the DIN rail, be sure to use the end
bracket to stop any side-to-side motion of the PLC, thus to
reduce the chance of the wires being pulled loose. At the
bottom of the PLC is a small retaining clip. To secure the
PLC to the DIN rail, place it onto the rail and gently push
up the clip. To remove it, pull down the retaining clip and
gently pull the PLC away from the DIN rail. As shown on
the right:
When installing the DVP
series PLC, make sure that it is
installed in an enclosure with
sufficient space (as shown
below) to its surroundings so as
to allow heat dissipation.

Wiring
22-16AWG
<1.5mm
Notes:
1Please use 22-16AWG (1.5mm) wiring (either single or multiple core) for I/O
wiring terminals. The specification for the terminals is as shown on the left. PLC
terminal screws should be tightened to between 5~8 kg-cm (4.3~6.9 in-lbs).
2I/O signal wires or power supply should not run through the same multi-wire
cable or conduit.
6.2 Wiring Notes
Environment
1. DO NOT store the PLC in an atmosphere that is dusty, smoky, with metallic debris or corrosive or flammable gases.
2. DO NOT store the PLC in an environment with high temperature or high humidity.
3. DO NOT install the PLC on a shelf or on an unstable surface.
Power Input Wiring
DVP-SA series input power supply is DC input. Please take a note of listed items when operating DVP-SA.
Series.

1. Please make sure the power is at terminals 24VDC and 0V (power range is 20.4VDC~28.8VDC). When voltage
is lower than 20.4VDC, PLC will stop operating, all outputs will turn Off and ERROR LED will flash continuously.
2. Please use wires of 1.6mm or above for the grounding of the MPU.
3. If the power-cut time is less than 10ms, the PLC still operates unaffectedly. If the power-cut time is too long or
the power voltage drops, the PLC will stop operating and all the outputs will be Off. Once the power is restored,
the PLC will return to operate automatically. (There are latched auxiliary relays and registers inside of the PLC,
please be aware when programming.)

Safety Wiring
Since the PLC is in control of numerous devices, motion of either one device could affect the motion of other devices,
therefore the breakdown of either one device would consequently be detrimental to the whole auto control system, and
danger will thus be resulted. Please use the recommended wiring below for the power input:
Power supply for AC loads
Power Circuit Protection Fuse (3A)
Power On pilot indicator
Emergency stop
The machinery must provide a quick manual method
disconnecting all system power.
Circuit isolation device (System Power Disconnect)
Utilize the electromagnetic contactor and the relay to be
the isolation unit of the power circuit to prevent the
possible instability of the system when the power is
supplied on and off.

1. There are two kinds of DVP-SA Series PLC output modules:
Relay and Transistor. For relevant electrical specification,
please refer to the function specification.
2. Be careful with the connection of the common terminals when
wiring outputs. For example, when wiring DVP12SA11R,
output terminal Y0 uses one common terminal C0, Y2 uses C1,
and Y2~Y3 share C2, as shown below:
Y0 Y1 Y2 Y3C0 C2C1
Action indication: When the output point is active, the
corresponding indicator at the front will be on.
3. Isolated circuit: The optical coupler is used to isolate signals
between PLC internal circuits and input modules.
7 TRIAL RUN
☼Power Indication
The “POWER” LED at the front of the MPU or the Expansion Units will be lit (in green) if the power is on. If the
indicator is not on when the MPU is powered up, it means that the 24V DC power supply of the PLC is overloaded.
It is thus necessary to remove the wiring on terminals +24V and 24G, and to use a 24VDC power supply instead. If
the ERROR LED is blinking swiftly, it suggests that the +24V power supply of the PLC is insufficient.
☼Low Voltage Indication
The “LOW V.” LED on the Expansion Unit is an indication that the input power voltage is insufficient, thus all outputs
of the expansion unit should be turned off.
☼Low Battery Voltage Indication
There is also a “BAT.LOW” LED at the front of the MPU. When the LED is on, it indicates that the battery voltage is
insufficient. Please change the batter (within 3 minutes) as soon as possible; otherwise the user programs and the
data in latched area may be lost.
Preparation
Prior to applying power, please verify that the power lines and the input/output wiring are correct. And be
advised not to supply AC110V or AC220V into the I/O terminals, or it might short-circuit the wiring and would
cause direct damage to the PLC.
After using the peripheral devices to write the program into the MPU and that the ERROR LED of the MPU is not
on, it means that the program in use is legitimate, and it is now waiting for the user to give the RUN command.
Use HPP to execute the forced On/Off test of the output contact.
Operation & Test
If the “ERROR” LED of the MPU is not blinking, use RUN/STOP switch or the peripheral devices (HPP or WPLSoft)
to give the RUN command, and the RUN indicator will then be on. If the “RUN” LED is not on, it indicates that there
is no program inside the PLC.
HPP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and the data
register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action. If the
ERROR LED is on (but not blinking), it means that the setting of the user’s program has exceeded the preset
overtime limit, thus users have to double check the program and perform the On/Off function again. (The PLC is at
this moment back to STOP automatically)
PLC Input/Output Reaction Time
The total reaction time from the input signal to the output operation is calculated as follows:
Reaction Time = input delay time + program scan time + output delay time
Input delay time 10ms (factory default), 0~15ms adjustable. Please refer to the
usage of special registers D1020~1021.
Program scan time Please refer to the usage of special register D1010.
Output delay time Relay module: 10ms. Transistor module: 20~30us.
Basic Commands and Application Commands of the PLC:
◎ The basic commands and the application commands of the MPU of this series are totally applicable to the
DELTA DVP-PLC EP Series MPU. Refer to the DELTA PLC Technique Application Manual for relevant basic
commands and application commands.
◎ The DVPHPP handheld programming panel and the WPLSoft (the Windows version) editing program of the
ladder diagram are both good for use with the DELTA DVP-PLC. Also, the PLC could connect with the
DVP12SA MPU through specific transmission wire to execute the program transmission, the MPU control and
the program monitoring.

Judge the errors by the indicators on the front panel. When errors occurred on DVP PLC, please check:
☼“POWER” LED
There is a “POWER” LED at the front of the MPU. When the MPU is powered On, the green LED light will be 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.
☼PLC “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
editing program of the ladder diagram to give commands to make the PLC “RUN” or “STOP”.
☼“ERROR” LED
If incorrect programs are input to the MPU, or that the commands and the components exceed the allowable range,
the indicator will blink. At this moment, the user should check both the error codes saved in the MPU data register
D1004 and the Error Code Table below to correct the programs. The address that the error occurs will be stored in
data register D1137 (the address saved in D1137 is invalid in case of common loop error).
When the ERROR LED is on (not blinking), users should make a judgment from the special relay M1008 of the MPU.
If it is On, it indicates that the execution time of the program loop has exceeded the time-out setting (set by D1000).
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” command can be used to solve the problem.
☼“BAT.LOW” LED
When the battery voltage is low, the “BAT.LOW” LED will be on, and the battery should be replaced as soon as
possible; otherwise the user program and the data in latched area will be lost. (On the unplugged PLC, please change
the battery within 3 minutes to retain the PLC’s internal user programs and data).
☼“Input” LED
The On/Off signals of the input point could be displayed through the “Input” LED, or the status of the input point could
be monitored through the device monitoring function of HPP.
☼“Output” LED
Output LED indicates if the output signals are On or Off. Please check the following items when the LED On/Off
indication does not correspond to the commands: 1. Output contacts may be melted and stuck together due to a short
circuit or current overload. 2. Check wiring and verify that the screws are tight.
