  If the icon is flashing on the LCD display and the alarm is sounding twice every second on your Tuncmatik UPS, it indicates an overload. This can happen if the UPS is overloaded, or if devices connected to the UPS are being fed directly by the electrical network via the Bypass. It can also happen if the UPS is locked in Bypass mode after repetitive overloads. To resolve this, remove excess loads from the UPS output. If the UPS is locked in Bypass mode, remove excess loads, then shut down the UPS and restart it.

  If the battery backup time on your Tuncmatik UPS is shorter than expected, it could be due to the batteries not being fully charged or the batteries being defective. First, charge the batteries for at least 5 hours and then check the capacity. If the problem continues, it may be necessary to contact your dealer to replace the battery.

  If your Tuncmatik UPS shows no indication and alarm even when the mains is normal, it could be due to a couple of reasons. First, check if the AC input power cord is firmly connected to the mains. Second, make sure the AC input is correctly plugged into the AC input, not the UPS output.

  If the icon and warning code are flashing on the LCD display and the alarm is sounding every second on your Tuncmatik UPS, it could be due to several reasons: * The EPO function might be activated. If so, set the circuit in a closed position to disable the EPO function. * The line and neutral conductors of the UPS input might be reversed. Rotate the mains power socket by 180° and then connect it to the UPS system. * The external or internal battery might be incorrectly connected. Check if all batteries are connected well.

  If fault code 14 is shown, the icon is lighting on the LCD display, and the alarm is continuously sounding on your Tuncmatik UPS, it indicates that the UPS shut down automatically because a short circuit occurred on the UPS output. Check the output wiring and if connected devices are in a short circuit status.
