- The diode is rated for maximum reverse voltage of 5 to 10 times the load voltage.- The forward current is more than the load current.6 TRIAL RUNƁ Power IndicationThe “POWER” LED at the front of the ELC will be lit (in green) if the power is on.Ŷ Low Battery Voltage IndicationThere is also a “BAT.LOW” LED at the front of the ELC. When the LED is on, it indicates that the battery voltage isinsufficient. Please change the battery (within 3 minutes) as soon as possible; otherwise the user programs and thedata in latched area may be lost.Ŷ Preparation1. Prior to applying power, please verify that the power lines and the input/output wiring are correct. Andbe advised not to supply AC110V or AC220V into the I/O terminals, or it might short-circuit the wiringand would cause direct damage to the ELC.2. After using the peripheral devices to write the program into the ELC and that the ERROR LED of theELC is not on, it means that the program in use is legitimate, and it is now waiting for the user to givethe RUN command.3. Use ELC-HHP to execute the forced On/Off test of the output contact.Ŷ Operation & TestIf the “ERROR” LED of the ELC is not blinking, use RUN/STOP switch or the peripheral devices (ELC-HHP orELCSoft) to give the RUN command, and the RUN indicator will then be on. If the “RUN” LED is not on, it indicatesthat there is no program inside the ELC.ELC-HHP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and thedata register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action. If theERROR LED is on (but not blinking), it means that the setting of the user’s program has exceeded the presetovertime limit. At this time, please turn RUN/STOP switch to STOP and get program time-out address from specialregister D1008. (it is recommended to improve by WDT command)Ŷ ELC Input/Output Reaction TimeThe 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 timeInput delay time Factory setting is 10ms. Please refer to 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.Ŷ Basic Commands and Application Commands of the ELC:1. The basic commands and the application commands of the ELC of this series are totally applicable to theELC. Refer to the ELC Technique Application Manual for relevant basic commands and applicationcommands.2. The ELC-HHP handheld programming panel and the ELCSoft (Windows version) editing program of theladder diagram are both good for use with the ELC. Also, the ELC could connect with theELC-PC12NNDR/T,ELC-PC12NNAR through specific transmission wire to execute the programtransmission, the ELC control and the program monitoring.7 TROUBLESHOOTINGJudge the errors by the indicators on the front panel. When errors occurred on ELC, please check:Ɓ “POWER” LEDThere is a “POWER” LED at the front of the ELC. When the ELC is powered On, the green LED light will be on.Ɓ ELC “RUN” LEDIdentify the status of the ELC. When the ELC is in operation, this light will be on, and users could thus useELC-HHP or the editing program of the ladder diagram to give commands to make the ELC “RUN” or “STOP”.Ɓ “ERROR” LEDIf incorrect programs are input to the ELC, the indicator will blink. Please check D1004(Error code) andD1137(Error step number).When the ERROR LED is on (not blinking), it indicates that the execution time of the program loop hasexceeded the time-out setting (set by D1000). Please turn the ELC RUN/STOP switch to STOP, and find out theaddress of the time-out program by special data register D1008. ”WDT”. After completing modifying program,user only need to reload program and this LED will be off at this moment. Once the LED still lights, please turnoff the power and check if there is interference or any conductive material in ELC.Ɓ “BAT.LOW” LEDWhen the battery voltage is low, the “BAT.LOW” LED will be on, please change the battery within 3 minutes toretain the ELC’s internal user programs and data).Ɓ “Input/Output” LEDThe On/Off signals of the input point could be displayed through the “Input” LED. “Output” LED indicates if theoutput signals are On or Off.³5656´/('³56´/('ZLOOOLJKWZKHQ56LVUHFHLYLQJGDWD³56´/('ZLOOOLJKWZKHQ56LVWUDQVIHUULQJGDWD
