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, as shown in figure 1. 2. When the peripheral devices are used to write program into PLC: If the ERROR indicator does not flash, the program you are using is legal and PLC is waiting for RUN instruction from you.

Please install PLC in an enclosure with sufficient space around it to allow heat dissipation (see figure 3). Sink Type Input point loop equivalent circuit DC Signal IN 2. When PLC is in operation, use HPP or WPLSoft to monitor the set value or temporarily saved value in timer (T), counter (C), and register (D) and force On/Off of output contacts. That the ERROR indicator is on (not flashes) indicates that part of the program exceeds the preset time-out. In this case, you have to set the RUN/STOP switch as STOP first, check special register D1008 D1008 and obtain the location in the program where time-out takes place. We suggest you use WDT instruction to correct this problem.

LOAD Power input wiring The power input of DVP-SV series is DC. When operating SV series, please make sure that: 1. The power is connected to the two terminals, 24VDC 24VDC and 0V, and the range of power is 20.4VDC ~ 28.8VDC. If the power voltage is less than 20.4VDC, PLC will stop running, all outputs will go "Off" and ERROR indicator will flash continuously. 2. The power shutdown of less than 10 ms will not affect the operation of PLC. However, power shutdown time that is too long or the drop of power voltage will stop the operation of PLC and all outputs will go "Off". When the power supply turns normal again, PLC will automatically return to its operation. (Please be aware of the latched auxiliary relays and registers inside PLC when programming.)

If the ERROR indicator keeps flashing, you have to check the special relay M1008 M1008. M1008 M1008 is on indicates that the execution time of program loop exceeds the preset time-out (in D1000 D1000). In this case, turn the RUN/STOP switch to STOP, check the special register D1008 D1008 and obtain the location in the program where the time-out takes place. We suggest you use WDT instruction to correct this problem. After amending the program, you only need to resend the program to stop the indicator from flashing. If the indicator still keeps flashing at this time, switch off the power and check if there is any interference existing or conductive invader inside PLC. 5 RY 20.4V~28.8V 0V If you enter illegal program into PLC or use instructions or devices that exceed their range, this indicator will flash (approx. every 1 second). When this happens, you have to obtain the error code from D1004 D1004 and save the address where the error occurs in register D1137 D1137 (if the error is a general circuit error, the address of D1137 D1137 will be invalid). Find out the cause of the error, amend the program and resend the program to PLC. If you cannot connect to PLC and this indicator keeps flashing quickly (approx. every 0.2 second), there should be insufficient 24VDC 24VDC power supply. Please check if the 24VCD 24VCD is overloaded. For details of error codes (in D1004 D1004, hex coding), see "DVP-PLC Application Manual: Programming". DVP-*-*-*-R LOAD 24V 1. C0 TRANSISTOR OUTPUT LED ERROR indicator < 0.3A Y0 DC power input POWER indicator When PLC is powered, the POWER LED indicator on the front panel will be on (in green). That this indicator is not on or the ERROR indicator continuously flashes when PLC is powered indicates that the power supply +24V is insufficient or DC power supply 24V is overloaded. In this case, change another DC24V DC24V power supply. If the indicator is still off at this time, your PLC is malfunctioned. Send your PLC back to your distributor for repair. 2. 4. Output terminals, Y0 and Y1, of transistor models use C0 common port; Y2 and Y3 use C1 common port; Y4 and Y5 use C2 common port; Y6 and Y7 use C3 common port; Y10, Y11, Y12 and Y13 use C4 common port, as shown below. DVP-*-*-11-T -11-T 5.2 Notes To identify abnormality from the indicators on the panel, please check: RUN indicator Check your PLC status. When PLC is running, this indicator will be on. You can use HPP, the ladder diagram editing program or the switch on the panel to RUN or STOP PLC.

The basic sequential instructions and application instructions of DVP-SV series are compatible with all Delta DVP series PLCs. See Delta "DVP-PLC Application Manual" for relevant information. 2. All Delta DVP series PLCs are compatible with DVPHPP handheld programming panel, WPLSoft ladder diagram for program editing and exclusive transmission cables to connect with DVP28SV DVP28SV for program transmission, MPU control, program monitoring and so on. Source Type 1. DVP-SV series have two output modules, relay and transistor. See "Function Specifications" for their specifications. Figure 1 Operation & test 1. If the ERROR indicator does not flash, you can use RUN/STOP switch or peripheral device (HPP or WPLSoft) to give RUN instruction and the RUN indicator should be continuously on at this time. That the RUN indicator does not flash indicates PLC has no program in it.

The lithium-ion battery has been fully charged in the factory and is able to retain the latched procedure and data storage for 12 months. If DVP28SV DVP28SV has not been powered and used for more than 12 months, the battery will be out of power upon normal consumption and the procedure and data will be lost. 3. The lithium-ion battery has longer life span than ordinary battery; therefore there is no need to change battery very frequently. You can charge the battery at any time without having to worry its chargeability will decrease. You can also recharge the battery even when there is still power in the battery. 4. Please be aware of the date of manufacturing; the charged battery can sustain for 12 months from this date. If you find out the BAT.LOW indicator stays on after PLC is powered, the battery voltage is low and the battery is being charged. DVP28SV DVP28SV has to remain on for more than 24 hours to fully charge the battery. If the indicator turns from on to "flash" (every 1 second), it indicates that the battery cannot be charged anymore. Please correctly process your data in time and send the PLC back to Delta for changing a new battery. Input indicator On/Off of input point is indicated by input indicator or monitored by HPP. 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. Use of electronic switch with too much electricity leakage often results in unexpected actions of the input point. MC2 < 0.5A LED 1. The rechargeable lithium-ion battery in DVP-28SV DVP-28SV is mainly used on the latched procedure and data storage. 4 2 3 TRANSISTOR OUTPUT 3 DC power supply Emergency stop Circuit protection fuse Flywheel diode (SB360 SB360 3A 60V) + inductive load Manually exclusive output: Uses external circuit and forms an interlock, together with the PLC internal program, to ensure safety protection in case of any unexpected errors. Trial Operation Preparation 1. Before powering DVP28SV DVP28SV, be sure that you have checked if the I/O wiring is correct. You may damage PLC if AC110V AC110V or AC220V AC220V is directly supplied to input terminals or the output wiring is short-circuited. Output 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.
