RLL233 Issue 4 Aug 2007 18 [14] REPLACEMENT OF MOTOR SUPPLY CABLE. TO REMOVE OLD CABLE AND CHAIN Ensure that the machine is disconnected from any source of power. Failure to do so may result in personal injury. • Remove screws #73 and withdraw the control unit from the housing. • Disconnect the nine-pin cable connector from the control panel • Remove the motor supply cable leads (8 and 9) from the terminal block by unfastening the screws. • Release the cable clip inside the housing cavity. • Rotate the capstan to raise the motor & gearbox assembly to the maximum up position (ensure that cutter retaining screws #11 do not foul arbor support bracket #7). • Remove the cable chain anchor screw #68 and release the cable chain #29. • Remove capstan retaining screw #49 and withdraw capstan assembly #55 • Withdraw the motor and slide assembly from the housing. • Remove screws #18 and separate motor and slide. • Remove the cable from the cable chain. • Remove screws #67 and cable cover #66. • Release the cable from the cable clip and terminal blocks. TO REFIT NEW CABLE. • Reverse the above procedure. • Now test the machine as described below: Earth Continuity Test A current of 25A having a no load voltage of 6v is passed between the earth contact of the mains plug and the frame of the machine. With the standard 3m length of cable the resistance shall not exceed 0.3 ohms. If this figure is exceeded, a faulty earth connection has been made. It must be found and rectified. Insulation Resistance Test With the magnet switch in the ON position, apply a voltage of 1.5kv between the live connection on the mains plug and the frame of the machine for a duration of 7 seconds. The reading obtained should not fall below infinity. Should a fault be indicated it must be found and rectified. REPLACEMENT OF MAINS SUPPLY CABLES RD271 and RD272 RLL233 Issue 4 Aug 2007 19 The replacement is a complete factory produced assembly, and RD272 (230v) is illustrated below. TO REMOVE OLD CABLE FROM MACHINE • The machine MUST be disconnected from any source of power supply before attempting to conduct any maintenance work. Failure to do so may result in personal injury. • Remove control unit by unfastening screws #73 and lifting the unit clear of the housing. • Remove the 9-pin connector block on the rear of the control unit. • Wires which are fastened into the block and not from the mains cable must not be released. Unfasten the terminal screws marked L & N and release the mains cable wires. • The mains supply cable is now only connected to the earth terminal, which is located in the housing cavity. Release the top nut of the assembly and extract the wire from under the saddle c...
