Delta Electronics DVP-Slim How to identify abnormality of PLC, Trail Operation, Notes

ƒHow to Install DIN Rail

DVP-PLC can be secured to a cabinet by using the DIN rail of 35mm in height and 7.5mm in depth. When mounting PLC to DIN rail, be sure to use the end bracket to stop any side-to-side movement of PLC and reduce the chance of wires being loosen. A small retaining clip is at the bottom of PLC. To secure PLC to DIN rail, place the clip onto the rail and gently push it up. To remove it, pull the retaining clip down and gently remove PLC from DIN rail.

ƒWiring

	1.	Use 22-16AWG (1.5mm) single or multiple core wire on I/O wiring
	22-16AWG	terminals. The specification of the terminal is shown in the figure on
		the left. The PLC terminal screws shall be tightened to 1.95 kg-cm
		(1.7 in-lbs).
< 1.5mm
	2.	DO NOT place the I/O signal wires and power supply wire in the
		same wiring duct.
	3.	Use 60/75ºC copper wires only.

DO NOT install PLC in an environment with:

hDust, smoke, metallic debris, corrosive or flammable gas

h High temperature, humidity

hDirect shock and vibration

3.4 Notes

ƒDuring the Engineering

1.DO NOT drop tiny metallic conductor into the PLC when screwing and wiring.

2.There should be a margin of more than 50mm between the PLC and other control device and the PLC should be placed away from high voltage wire and power equipments.

ƒArrangement of I/O Points

No matter the MPU with how many points you are using, the input point No. of the first connected extension unit has to start from X20 and output point No. from Y20. The connection of MPU and extension units is demonstrated in the figure below.

the ERROR indicator is on (not flashes) indicates that part of the program exceeds the preset time-out. In this case, you have to check the program and set On/Off of the power again (PLC automatically returns to STOP status at this time).

\How to identify abnormality of PLC

5.1 PLC Abnormality

To identify abnormality from the indicators on the panel, please check:

ƒ“POWER” Indicator

When PLC is powered, the POWER LED indicator on the front panel will be on (in green). If the indicator is not on, check if the power supply is normal. If the problem still exists, your PLC is malfunctioned. Please change a new one or send your PLC back to your distributor for repair.

ƒ“L.V” Indicator

That the “L.V” indicator on the extension unit is on indicates that the input voltage for the power of the extension unit is insufficient and all outputs from the extension unit will be disabled.

ƒInput Indicator

On/Off of input point is indicated by input indicator or by the monitoring function of the device. When the action criteria of the input point are true, this indicator will be on. If abnormality is identified, check if the indicator and input circuit are normal by HPP/WPLSoft. Use of electronic switch with too much electricity leakage often results in unexpected actions of the input point.

ƒOutput Indicator

On/Off of output point is indicated by output indicator. When the output indicator (On/Off) does not correspond to the action of its load, please be aware of the follows:

1.The output contact may be melted or blocked out of overloading or short-circuited load, which will result in poor contact.

2.If you are suspicious that the output point may execute undesired action, check the output wiring circuit and whether the screw is properly tightened.

*1: Manual exclusice output uses external circuit and forms an interlock, together with the PLC internal program, to ensure safety protection in case of any unexpected errors.

*2: Zener diode (39V) inside PLC protects the transistor output. When activating an inductive load, we suggest you parallely connect a reverse current protection diode.

[Trail Operation

ƒPOWER Indicator

The “POWER” LED indicator on the front panel of PLC MPU or extension unit will be on (in green) when the MPU is powered. That the MPU is powered but the indicator is not on indicates that the DC power supply of the PLC is abnormal. Please check if the terminal wirings of +24V and 0V are correct. That the “ERROR” LED indicator flashes continuously indicates that the +24V power supply for the PLC is insufficient. That the “L.V” indicator on the extension unit is on indicates that the input voltage for the power of the extension unit is insufficient and all outputs from the extension unit will be disabled.

ƒPreparation

Before powering, make sure that you have checked if the I/O wiring is correct. You may damage the PLC if AC110V or AC220V is directly supplied to input terminals or the output wiring is short-circuited. When the peripheral devices are used to write program into PLC and if the ERROR indicator does not flash, the program you are using is legal and PLC is waiting for RUN instruction from you. You can use HPP to test “force On/Off” of output contacts.

ƒOperation & Test

If the ERROR indicator does not flash, you can give RUN instruction to the peripheral device and the RUN indicator should be continuously on at this time. When PLC is in operation, use HPP to monitor the set value or temporarily saved value in the timer (T), counter (C), and register (D) and force On/Off of output contacts. That

DVP series PLC does not utilize any disposable components; therefore, you do not need to replace most of the components with new ones. However, if the output relay is used for activating big current load, the life of output contact will be shortened. In this case, you will need to check whether the contact is in permanently “open circuit” or “short circuit” and note that::

1.DO NOT place the PLC under direct sunlight and avoid placing it close to an over-heated object in case the high temperature will affect the functions of the PLC.

2.Clean the airborne dust or metallic particles in the panel on a regular basis.

3.Check regularly that if the wiring and terminals are tightened properly.

5.3Suggestions for Operation

DVP series pin-headed digital extension unit is relatively more sensitive to the temperature in the operation environment; therefore, when using the unit, please note that:

1.The lift of I/O points will be shortened if the voltage and the temperature are too high in the external environment.

2.When the external voltage is larger than 24VDC, it is suggested that the output load current be reduced to below 0.1A.

3.To sum up, operate the unit in 55ºC/1A (COM), 25ºC/2.4A (COM); otherwise, the life of I/O points will be shortened.
