Troubleshooting

This section provides troubleshooting instructions for S10 Online System.

Table 1. Troubleshooting

Net Bridge in general
VCC, 5V, VDD, 5V BUSNot illuminatedNet Bridge hardware failure.Replace Net Bridge.
DC/POE/POE+Not illuminatedPowering issue.Check fuse F1. Check power supply.
Net Bridge in the OPERATING mode
RS-485 STATUSRedPower issue on a bus device.Check the connections for shortcuts and misconnections.
RS-485 STATUSBlinking red

The configuration detected on the bus differs from the one that was saved when last finalizing the bus device configuration. For example:

  • There are less or more devices on the bus, or slaves connected to a Door Module, than there should be.
  • The OPTIONS dip switch setup of a Door Module has been changed.
  • A Door Module programming state has been changed.
  • If you have changed the configuration on the bus on purpose, re-finalize the new bus configuration by running setup again, see Finalizing the Bus Device Configuration on Net Bridge.
  • If you have not changed the configuration on the bus, check the wiring to the bus devices, and slaves connected to the Door Module. The affected Door Module indicates the error by blinking red four times.
RS-485 STATUSOrangeLow voltage issue on a bus device.Too long cabling or too many devices on the bus. Double the power wiring or reduce the amount of devices on the bus. If PoE is used, use PoE+ or an external power supply instead.
RS-485 STATUSBlinks orangeFirmware update in progress.Do NOT power off the device. See Software and Firmware Updates.
RS-485 STATUSOffNo devices were found on the bus.Check the bus device connections. Finalize the Net Bridge configuration, see Finalizing the Bus Device Configuration on Net Bridge.

The configuration detected on the Door Module differs from the one that was saved when last finalizing the bus device configuration. For example:

  • There are less or more slaves connected to a Door Module, than there should be.
  • The OPTIONS dip switch setup of a Door Module has been changed.
  • A Door Module programming state has been changed.
  • If you have changed the configuration on the bus on purpose, re-finalize the new bus configuration by running setup again, see Finalizing the Bus Device Configuration on Net Bridge.
  • If you have not changed the configuration, check the wiring to the slaves connected to the Door Module.

  • Check the wiring.

  • Ensure that the Net Bridge configuration has been finalized.

The table below lists troubleshooting instructions not related to any specific device LED.

ProblemSolution

When finalizing the bus device configuration on Net Bridge, the FUNC led indicates less devices than connected.

A connected device appears in the device list of the Net Bridge on S10 Manager, but cannot be programmed remotely.Ensure that the user ID attached to the Net Bridge has all zones.
1 The LED blinks red on one-second intervals until a pause of a couple of seconds. The number of blinks in the sequence indicates the problem number.
