    What to do if there is no HIGH level output at the Lenze EPM-T1 digital output?
    • C
      Christopher RobinsonAug 14, 2025
      If the Lenze I/O Systems digital output doesn't show a HIGH level, there might be a few reasons: * There could be a short circuit due to incorrect wiring: In this case, you should check the wiring. * The connected load might be defective: In this case, check the load. * The digital output may be overloaded because the load's current consumption is too high: Try selecting a load with lower current consumption. If you're using an 8×digital output 1A module, consider replacing it with an 8×digital output 2A module if possible.

    Why is there no data transfer in my Lenze EPM-T1 I/O Systems?
    • F

      If the Lenze I/O Systems is not transferring data, it might be due to the module not receiving the necessary 24 V DC supply voltage. Ensure the module is properly supplied with 24 V DC.

    What to do if the Lenze EPM-T1 relay contact does not open?
    • G
      garrett02Aug 21, 2025
      If the Lenze I/O Systems relay contact isn't opening, it's possible that excessive load has caused the relay contact to fuse. You should replace the module and reduce the load on the relay contact.

    What to do if the signal at the Lenze EPM-T1 I/O Systems analog input is not transmitted?
    • C
      carolyn17Aug 25, 2025
      If the Lenze I/O Systems are not transmitting the signal at the analog input, consider the following possibilities: 1. There might be an open circuit within the measuring range of 4 ... 20 mA, so check the wiring. 2. There may be no sensor connected, so connect the sensor. If an input is not in use, short-circuit the plus and minus terminals. 3. The input current might be greater than 40 mA, so reduce the input current.

    Why is no process data transmitted in my Lenze EPM-T1?
    • M
      Matthew StoneAug 27, 2025
      If the Lenze I/O Systems are not transmitting process data, it could be because the system bus is in the "Pre?Operational" state. To resolve this, transmit telegram 00 01 00 from the master to change the system bus to the "Operational" state.

    How to fix incorrect data transmission to the backplane bus in Lenze EPM-T1 I/O Systems?
    • H
      Haley SimmonsAug 31, 2025
      If the Lenze I/O Systems module isn't making proper contact with the backplane bus, it can cause incorrect data transmission. To solve this, place the module on the DIN rail and turn it downward until you hear it engage. Then, restart the module by disconnecting and reconnecting the supply voltage.

    What to do if Lenze EPM-T1 parameter changes were not saved after supply voltage disconnection?
    • H
      Holly HamiltonSep 3, 2025
      If changes to parameters on your Lenze I/O Systems aren't being saved after you disconnect the supply voltage, it's likely because the parameter changes were not saved. To ensure changes are saved, use index I2003h to save all settings.

    Why HIGH signal at a digital input is not transmitted/indicated in Lenze EPM-T1?
    • J
      Jennifer ParkerSep 6, 2025
      If the HIGH signal at a digital input on your Lenze I/O Systems is not being transmitted or indicated, it could be due to the high signal lacking a reference potential (GND) via pin 10. To fix this, establish a reference potential.

    Why value 0 is not transmitted to the master via the digital input IN1 / IN4 after a reset in Lenze EPM-T1?
    • G
      gregoryparkSep 9, 2025
      If, after a reset, the value 0 is not transmitted to the master via the digital input IN1 / IN4 when networking takes place via system bus (CAN) or CANopen with your Lenze I/O Systems, it is because the process data transfer to the master (PDO?Tx) is event?controlled. Setting cyclic process data change (I1800h ... I1809h) should resolve the issue.
