Error Codes List page 21

  • Code: SC544-01
  • Description: Fusing central thermopile high temperature detection (hardware) In the event of an error
  • Causes: • Triac defective (short-circuit) • Engine controller defective • Heating central thermopile defective • Fusing control software: out of control
  • Remedy: • If the triac is defective, replace the AC power supply board • If necessary, replace the BCU or the heating central thermopile
  • Code: SC544-02
  • Description: Fusing central NC sensor high temperature detection (hardware) In the event of an error
  • Causes: • Triac defective (short-circuit) • Engine controller defective • Heating central thermopile defective • Fusing control software: out of control
  • Remedy: • Attach the new fusing unit, then run SP-5-810-002 • If the triac is defective, replace the AC power supply board • If necessary, replace the BCU or the Fusing central NC sensor
  • Code: SC545-00
  • Description: Fusing central heater continuously Heat After waiting for full power for more than (t6) seconds continuously, not detected for (t8) seconds. • Definition of heater full power Continuously heating rate set point (maximum heating rate) • Measurement start point After reload (after heater extinguished, after rotation complete) below the standby temperature (target temperature), measurement starts after a heater heat-up request is issued. • Measurement stop condition Rotation started due to a print signal during measurement or other. • Maximum heat-up Duty (SP interlinked value) 0% is excluded.
  • Causes: • Thermistor deformation/float • Heater disconnection • After excessive temperature rise prevention unit operates
  • Remedy: • Replace the thermistor • Replace the fusing lamp • Replace the fusing unit
  • Code: SC547-01
  • Description: Zero cross error (relay-contact soldering) In the event of an error
  • Causes: • Fusing relay defective (contact soldering) • Fusing relay drive circuit fault
  • Remedy: • Turn the main power supply switch OFF/ON • If the fusing relay is damaged, replace the PSU • Check the connection between PSU and control board, and replace harness and board if necessary
  • Code: SC547-02
  • Description: Zero cross error (relay contact fault) In the event of an error
  • Causes: • Fusing relay damage (contact open) • Fusing relay drive circuit fault • PSU fuse (24VS) blowout
  • Remedy: • Turn the main power supply switch OFF/ON • If the fusing relay is damaged, replace the PSU • Check the connection between PSU and control board, and replace harness and board if necessary • If the PSU fuse (24VS) blows out, replace the fuse
  • Code: SC547-03
  • Description: Zero cross error (low-frequency error) In the event of an error
  • Causes: Frequency instability of commercial power line
  • Remedy: • Turn the main power supply switch OFF/ON • Check the power source • Check the connection between PSU and control board, and replace harness and board if necessary
