Down Stop When solenoid D is de energized with solenoid C remaining de energized the car will stop according to the setting of adjustment 8 and no further adjustment will be required KS Slack Rope Valve The KS is adjusted with a 3 mm Socket Key by turning the screw K in for higher pressure and out for lower pressure With K turned all the way in then half a turn back out the unloaded car should descend when the D solenoid alone is energized Should the car not descend K must be backed off until the car just begins to descend then backed off a further half turn to ensure that with cold oil the car can be lowered as required ter ISO 9001 2000 6 Troubleshooting Up Travel For checking the operation of the solenoids remove the top nuts By lifting the solenoids a few millimeters the magnetic pull of the solenoid can be felt For testing the operation of the elevator car can also be controlled by lifting and replacing the coil Valves are fully adjusted and tested in the factory Check electrical operation before changing valve setting 1 Test Turn adjustment 5 all the way in If the elevator now starts upwards the problem is at solenoid A 2 Solenoid A not energized or Lift coil to check magnetic pull voltage too low see above 3 Solenoid A tube not screwed Tighten Solenoid A tube down tight 4 Solenoid valve A dirt or Clean or chanae needle and damage between needle AN and seai seat AS
3. Screwing the relief pressure increases In the following diagram it is shown the hydraulic circuit of EV 100 HP During adjustment of the EV 100 valve instead of making a full floor to floor travel to check operation much time can be saved by removing the securing nuts of the coil and switching to deceleration or to acceleration by lifting or replacing the appropriate coil by hand allowing several adjustment corrections during one car travel between floors Caution Once removed from the solenoid tube the energized coil will begin to overheat after about 20 secs If necessary to slow the rate of heating place an 8 or 10 mm socket key or similar steel rod as core thru the coil Do not lay an energized coil to one side otherwise it may overheat unnoticed If the coil becomes too hot to hold it must be replaced back over the solenoid tube and any further adjustment carried out with the elevator making normal floor to floor runs Car not visible from Machine room lf the car cannot be seen during adjustment of the valve the acceleration and deceleration times can be heard from the change of the turbulent noise within the valve as the speed of the car changes With no load in the car the duration of the speed changes should be about 2 5 seconds This applies to adjustments 2 3 6 and 8 ISO 9001 2000 6 H x s Up Travel empty car Pre settings Adjustment No 1 level with flange face 5 mm Socket key Adjustment No 2 all
