What to do if Dynaset Construction Equipment magnet shuts down by itself after magnetization is started?
- J
  josecampbellAug 3, 2025
  If the Dynaset Construction Equipment magnet shuts down by itself after magnetization is started, it may be due to the generator's output voltage being too high, causing overloading. If you are using a CMG PRO generator with multiple control cards, check the connection between terminals 6 and 7 on the different cards. If the connection is lost, repair it. If the connection is in order, the control card may be broken and needs to be replaced.

What to do if Dynaset Construction Equipment HMAG PRO is spilling oil from the cover?
- M
  Mrs. Jacqueline Johnson DDSAug 13, 2025
  If oil spills from the Dynaset Construction Equipment HMAG PRO's cover, it's likely because the pressure line is connected while the return line is disconnected, and the pressure relief valve is leaking oil. Check the connection, connect the hoses to their correct places, and clean the spilled oil.

What causes Dynaset Construction Equipment magnet to suddenly drop collected metals after moving it?
- J
  Jennifer TurnerAug 17, 2025
  If the Dynaset Construction Equipment magnet drops collected metals after moving it, and it magnetizes after dropping the load, it's likely due to a drop in the system's hydraulic flow when moving the boom. The demagnetization begins too fast when the system’s hydraulic flow to the generator drops. The demagnetization delay has to be adjusted to be longer. Contact DYNASET for more information about adjusting the delay.

Why is there low output voltage at no load in Dynaset Construction Equipment?
- C
  Chris HarrisAug 23, 2025
  Low output voltage at no load in Dynaset Construction Equipment may be due to poor contact in the electric system. Inspect all internal contacts and wirings of the generator. Also, check and clean the brushes and slip ring.

What causes output voltage less than 20Vac in Dynaset Construction Equipment?
- R
  Richard JohnsonAug 27, 2025
  Output voltage less than 20Vac in Dynaset Construction Equipment is caused by excitation rectifiers failure. You should trace the failure and replace the rectifier (with Compound or Capacitor voltage regulator).

Why is Dynaset Construction Equipment magnet malfunctioning and the readout displayed when magnet current is under 2A?
- A
  Angela HendricksNov 6, 2025
  If the Dynaset Construction Equipment magnet malfunctions and the readout is displayed when the magnet current is under 2A, there could be several reasons: * The HMAG PRO’s hoses are cross-connected. * The generator is unplugged from the magnet, or the magnet cable is damaged. * The magnet coil is damaged. * The CMG PRO magnet generator won’t produce 220 VDC. To solve this: * Check HMAG PRO’s connection to the hydraulic circuit and rectify. * Switch off the generator. Check the cable and the connection to the magnet. Change the cable if it is damaged. * Check the coil’s resistance and compare the result to the value indicated in the magnet’s manual. Check also coil’s inductance if possible. * Turn off the generator. Check whether there is a DC voltage between the control...
