Solutions |
| 1. Be sure to turn the power off when connecting or disconnecting wires during trouble shooting of the power supply Is the unit plugged in? Is the proper voltage coming out of the wall outlet? Whether this is a Condor or a Protek Power Supply when set up for 110 volt operation the Power Supply should have an input voltage between 110 and 125 volts AC. When set up for 220 volt operation there should be an input voltage between 220 and 235 volts AC Is the power supply fuse blown? On Condor Power Supplies the fuse is located at the back of the autoclave above the line cord. The replacement fuse is 1.2 amps On Protek Power Supplies the fuse is located on the power supply itself. The replacement fuse for this supply is 2.0 amps Turn the power off and remove the Power Supply OUTPUT wires at the JP3 connector on the Ajunc Board, turn the power on and check the input side of the Power Supply for the correct input voltage. Do not disconnect the input wires yet. A 110 volt machine should have between 110 and 125 volts AC across the input wires A 220 volt machine should have between 220 and 235 volts AC across the input wires If no voltage is present then: Turn the power off and remove INPUT wires from Power Supply turn the power back on and check for the correct input voltage If line voltage is present on the input wires only when the wires are disconnected then replace Power Supply If line voltage is still not present with the wires disconnected, then: Check for loose or broken wires at the On/Off Switch Check for broken On/Off Switch Check for loose or disconnected Molex connector on the back of the Electronic Box Check for loose wires in the Molex connector on the back of the Electronic Box Remove both wires from the terminals of the Cut-Out Thermostat. Take an ohm reading across the two terminals to see if the device is closed. If not reset the Cut-Out Thermostat and test again. If continuity can not be seen then see the section on Safety Thermostat Problems Check that the line voltage appears across the output side of the Circuit Breaker or Fuses. If it can not be seen then check the section on Circuit Breaker and Fuse Problems Check the Line Cord is in good condition and conducting electricity |
