• A loose or open connection• An exceeded operational time limit• A power drop• An overtemperature conditionWhen a fault is detected, a message describing the fault displays in the Fault Diagnostics menu (LCD models). For modelsnot equipped with an LCD, use the Live Mode tab in the Software on a PC connected to Safety Controller with the SC-USB2 cable. Fault diagnostics are also available over the network. An additional message may also be displayed to helpremedy the fault.Note: The fault log is cleared when power to the Safety Controller is cycled.13.4.1 XS/SC26-2 Fault Code TableFault Code Displayed Message Additional Message Steps to resolve1.1 Output FaultBase Module or SolidState ModuleCheck for shortsRelay Modulen/aBase Module or Solid State ModuleA Safety Output appears On when it should be Off:• Check for a short to the external voltage source• Check the DC common wire size connected to the Safety Outputloads. The wire must be a heavy-gauge wire or be as short as possibleto minimize resistance and voltage drop. If necessary, use a separateDC common wire for each pair of outputs and/or avoid sharing this DCcommon return path with other devices (seeCommon Wire Installationon page 51)Relay Module• Replace Relay module1.2 Output FaultBase Module or SolidState ModuleCheck for shortsRelay Modulen/aBase Module or Solid State ModuleA Safety Output is sensing a fault to another voltage source while the output isOn:• Check for a short between Safety Outputs• Check for a short to the external voltage source• Check load device compatibility• Check the DC common wire size connected to the Safety Outputloads. The wire must be a heavy-gauge wire or be as short as possibleto minimize resistance and voltage drop. If necessary, use a separateDC common wire for each pair of outputs and/or avoid sharing this DCcommon return path with other devices (seeCommon Wire Installationon page 51)Relay Module• Replace Relay module1.3 – 1.8 Internal Fault - Internal failure—Contact Banner Engineering (seeRepairs and Warranty Serviceon page 155)1.9 Output Fault Internal Relay Failure • Replace Relay module1.10 Output Fault Check Input Timing Sequence timing error:• Perform a System Reset to clear the fault2.1 Concurrency Fault Cycle InputOn a dual-channel input, or a complementary input, with both inputs in the Runstate, one input went to the Stop state then back to Run.On a dual-complementary input, with both pairs of inputs in the Run state, onepair of inputs went to the Stop state then back to Run.• Check the wiring• Check the input signals• Consider adjusting the debounce times2.2 Simultaneity Fault Cycle InputOn a dual-channel input, or a complementary input, one input went into the Runstate but the other input did not follow the change within 3 seconds.On a dual-complementary input, one pair of inputs went into the Run state butthe other pair of inputs did not follow the change within 3 seconds.• Check the wiring• Check the input signal timingXS/SC26-2 and SC10-2 Safety Controllers148 www.bannerengineering.com - Tel: + 1 888 373 6767
