EV 100 Service Manual
Solenoid Coils
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 energised 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 energised 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 Machineroom
If 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.

PRE-SETTINGS
Adjustment No. 1
Adjustment No. 2 all the way in then 2 turns out.
Adjustment No. 3
Adjustment No. 4
Adjustment No. 5 all the way in then 4 turns out.
Adjustment No. S
1. Pilot Pressure Setting
Disconnect coil A. Energise Motor (pump).
If the car does not move, turn No. 1 in until the car begins to move, turn No. 1 out until the car stops, then back out
again 1/2 turn. The car remains standing still.
DO NOT UP-LEVEL WITH THIS ADJUSTMENT! Between full and empty car, leveling speed differences would be
extreme.
2. Up Acceleration
Reconnect coil A. Start Motor and energise coil A and B (normal up call).
Observe the up acceleration. If it is too quick, turn No. 2 in ½ turn. If it is too long, turn No. 2 out ½ turn.
Repeat until acceleration is satisfactory. Acceleration time should be about 2,5 secs.
4. Up Leveling
Disconnect coil B. Energise Motor and coil A (normal up-level call).
With adjustment No. 4 level with the face of the flange the car will up level. If the leveling speed is too fast,
turn No. 4 in until the speed is as required. If the speed is too slow, turn No. 4 out. Recommended speed
6 cm/sec.
