What to do if my Schaerer Medical Equipment table seems powerless?
- N
  Nicholas AguilarAug 17, 2025
  If your Schaerer Medical Equipment table appears to have no power, even when plugged in, there are several potential causes. First, check if the facility circuit breaker has tripped, and if so, determine the cause and reset or replace it. Second, inspect the 5 amp fuses in the power cord receptacle and replace any that are blown. Third, check the RFI filter and replace it if necessary. Fourth, replace the line power pilot lamp if it's burned out. Finally, examine the wires and connections between the power cord receptacle and transformer, cleaning dirty connections, tightening loose ones, and replacing any broken components.

What to do if my Schaerer Medical Equipment hand control does not work?

  If your Schaerer Medical Equipment hand control isn't working, start by checking the 10 amp fuse on the main controller board and replace it if blown. If the fuse is fine, the main controller board or hand control board might be malfunctioning. Also, inspect the wires and wire connections between the main controller board, distribution board, and hand control port for any breaks, looseness, or dirt. Clean, tighten, or replace as needed. Lastly, a closed motor pump secondary thermostat creating a short to ground may cause the 40 amp fuse on the charging / power driver board to blow. Replace the malfunctioning motor, secondary thermostat, and 40 amp fuse in this case.

What to do if my Schaerer Medical Equipment table's line power pilot lamp illuminates, but batteries don't recharge?
- C
  cpierceAug 30, 2025
  If the line power pilot lamp on your Schaerer Medical Equipment table illuminates but the batteries do not recharge, and the table is powerless even with the power cord plugged in, there are several potential causes. The thermal fuse(s) in the transformer could be blown, or the transformer itself might be blown. Alternatively, the charging / power driver board could be malfunctioning, or the wires and wire connections between the transformer and charging / power driver board might be broken, loose, or dirty. You can try cleaning any dirty connections, tightening loose connections, and replacing any broken connectors or wires. If the issue persists, consider replacing the transformer or the charging / power driver board.

  If all functions on your Schaerer Medical Equipment are running too slowly, it could be due to several reasons.

  Kristopher HarrisSep 9, 2025
  If the floor lock cylinders on your Schaerer Medical Equipment do not retract when the ENABLE and UNLOCK buttons on the hand control are pressed, it could be due to a clogged floor lock valve spool, dirty inside surfaces of the main floor lock cylinder, or a malfunctioning pilot-operated check valve. To address this, you can remove the valve spool and clean out the valve spool ports, disassemble and clean the main floor lock cylinders, or remove the pilot-operated check valve components to clean out any foreign matter and replace any broken or bent components.
