EV100 / KV Service Manual
Quick adjustment
procedure
EN ISO 9001
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.

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 ½ turn.
The car remains standing still.
DO NOT UP-LEVEL WITH THIS ADJUSTMENT! Between full and empty car, levelling 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 Levelling
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 levelling 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.

3. Up Deceleration
With coil B still disconnected. Energise motor and coil A (normal ‘up-level’ call).
The car will travel upwards at levelling speed. Turn No. 3 ‘in’ until the car starts to up level faster, then
turn No. 3 ‘out’ until the original levelling speed is observed. Reconnect coil B and place a normal up call.
Observe the deceleration of the car. If it is too long, turn No. 3 ‘out’ ¼ turn; if it is too short, turn No. 3 ‘in’ ¼ turn.
Repeat until deceleration is satisfactory. Deceleration time should be about 2,5 secs.
5. Up Soft Stop
Disconnect coil A. Energise Motor.
The car should not move. Turn No. 5 ‘in’ until the car starts upwards then turn No. 5 ‘out’ until the car stops.
Reconnect coil A. Energise Pump-Motor and A. The car will travel upwards at levelling speed.
Lift A coil by hand briefly and observe the stopping of the car. If the stop is too hard turn No. 5 ‘in’ ¼ turn.
If the stop is too soft, turn No. 5 ‘out’, ¼ turn. Repeat until the stop is satisfactory.
S Pressure Relief Valve
Turn S screw ‘out’ until about 2 mm of the screw head is showing. Close the ball valve in the cylinder line
and open the manual lowering H to lower valve pressure down to zero. Place an up call, energising motor
and coils A and B. The relief pressure will show on the pressure gauge.
To increase the relief valve setting, turn S ‘in’.
To decrease the relief valve setting, turn S ‘out’, then open the manual lowering for ½ second with the pump
still running to release locked-in pressure, before observing the pressure gauge reading.

8. Down Deceleration
Place down call (coils C and D energised).
As the car approaches full speed, remove coil D by hand briefly from the solenoid and observe the deceleration of the car.
If the deceleration is too long, turn No. 8 ‘out’ ¼ turn; if it is too short, turn No. 8 ‘in’ ¼ turn.
Repeat until deceleration is satisfactory. Deceleration time should be about 2,5 secs.
6. Down Acceleration
Turn No. 6 all the way ‘in’. Place down call (coils C and D energised).
The car will not move. Turn No. 6 ‘out’ slowly until the car accelerates downwards.
If the acceleration is too long, turn No. 6 ‘out’ ¼ turn. If it is too short, turn No. 6 ‘in’ ¼ turn.
Acceleration time should be about 2,5 secs.
7. Down Full Speed
Place down call (coils C and D energised).
Observe full down speed. Turn No. 7 ‘in’ for slower, ‘out’ for faster speed.
9. Down Levelling Speed
Disconnect coil C. Place down call (D energised).
Observe down levelling speed. Turn No. 9 ‘in’ for slower, ‘out’ for a fast down levelling speed.
Recommended speed 6 cm/sec.
H Emergency Lowering
The manually operated emergency down speed and the D coil operated down levelling speed are the same.
Down Stop
When solenoid D is de-energised with solenoid C remaining de-energised, 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 energised.
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.

With no load in the car, the deceleration time should be 2 to 2,5 secs. from full speed to levelling speed.
The levelling time should be 1 to 2 secs.
Accurate landing can be affected by different factors as follows:
a. If the levelling speed is fast i.e. 0,1 m/sec (20 ft/min), landing will not be as accurate as when the levelling speed is slower i.e.
0,05 m/sec (10 ft/min).
b. If the soft stop adjustment ‘5’ is set too soft, stopping will be less accurate as when ‘5’ is set for a quicker stop.
c. Particularly when the mechanic can not see the operation of the elevator car, it is possible that the elevator has not finished
decelerating from fast speed before reaching the floor. In other words, the elevator has not slowed down to its correct levelling
speed before the stop switch is actuated.
Usually, the levelling operation can be observed through the crack in the car doors. Alternatively, in the machine room, the
turbulent noise within the valve during levelling can be heard and should last 1 to 2 secs. following 2 to 2,5 secs. deceleration
time with no load in the car.
d. A difference in landing accuracy between the elevator being loaded and unloaded, can be due to the car under load, leaning
to one side by several millimeters causing an alteration in the operating position of the stop switch by some centimetres.

Consider oil cooler if hot oil is a problem.
Valves are already adjusted and tested. Check electrical operation before changing valve settings. Test that the correct solenoid is energised, by removing nut
and raising solenoid slightly to feel pull.
A
For checking the operation of the solenoids, remove the top nuts. By lifting the coils a few millimeters, the magnetic pull of the coil can be felt. For testing, the
operation of the elevator car can also be controlled by lifting and replacing the coil.
If the coil gets too hot, the coil has to be mounted onto the solenoid and the following adjustments have to be carried out on normal travels from floor to floor.
Standard settings: Adjustments 7 & 9 approx. level with flange faces. Up to two turns in either direction may then be necessary. Adjustments 6 & 8 all the way in
(clockwise) then for EV ¾”, adjustment 6,1 ½ turn and adjustment 8, 1 turn out (c-clockwise), for EV 1 ½ “ – 2 ½”, adjustments 6 & 8, 1 ½ turns out (c-clockwise).
Small final adjustments may be necessary.

In the past, a small number of the original springs No. 9F have broken. Beginning January 2000, the design of the
down levelling adjustment was modified to take a stronger spring.
The complete new adjustment is interchangeable with the original adjustment 9.
A broken spring 9 would cause the down levelling speed to be slower. No danger to passengers would arise as a
consequence.

KV Elevator Control Valve
Trouble Shooting (2013)
UP Travel
Problem
Possible cause
Recommended
Test for KV1S and KV2S: Turn adjustment 5 all the way in, if the elevator now starts upwards the problem is at solenoid A.
No Up-Start
(Elevator
remains at floor).
Solenoid A not energised or voltage too low.
See A below.
Solenoid A tube not screwed down tight.
Tighten Solenoid A tube.
Solenoid valve A: Dirt or damage between needle and seat.
Clean or change needle and seat.
Orifice in bypass valve blocked.
Clean or change bypass valve U.
Adjustment 1 too far back (open). Not enough pilot pressure
(minimum 5 bar) or bypass flow guide too large
(slots too wide). see*
With the pump running, turn adjustment 1 in, or if already too far in, insert smaller bypass flow guide (see the
diagramm in KV literature).
Pressure relief valve S is set too low.
Set relief valve higher. Preadjustment all the way in and
then 1½ turn out.
Down valve 7 or 9 are open due to contamination in their orifices.
(Especially if the elevator settles back on the buffers.
Solenoid D is leaking.
Clean or replace down valves 7 (KV2 only) and 9.
Clean solenoid D.
Pump running in the wrong direction.
Check motor direction and install the pump correctly.
The pump connection flange is leaking excessively.
Seal the pump connection.
The pump is undersize, worn or crack in the housing.
Select a bigger pump or replace the pump.
* Test: If by turning adjustment 1 with the pump running the pressure does not rise above 5 bar, even with a smaller
bypass valve inserted, the problem should be sought at the pump.
Up-Start
too hard.
Elevator slows
down but over
travels the floor
level.
Relief-Valve
not adjustable
to lower value.
Elevator
doesn‘t reach
full speed.
Adjustment 1 turned in too far.
Turn out adjustment 1.
Bypass flow guide U too small (slots too narrow).
Change to flow guide with wider slots.
Star to delta motor switch period is too long.
0.2-0.3 sec. is sufficient.
O-ring UO on the bypass valve U is leaking.
Change O-Ring  see KV Spare Parts List.
Excessive friction on the guide rails or in the cylinder head.
Can not be eliminated through valve adjustment.
Solenoid A (Up-stop) is de-energised too late.
See A below.
Adjustment 5 (Soft Stop) not far enough open (KV1S and KV2S).
Open further out.
Adjustment 1 Bypass not far enough open and pump flow does
not completely by-pass.
Open adjustment 1 two turns further out.
Adjustment 1 too far in.
Open adjustment 1 further out.
½“ pipe thread connection in return line T should not exceed
14 mm.
With tape threads, 4-6 threads of engagement is
sufficient.
By-pass piston doesn‘t close. Dirt/foreign particeles in by-pass
piston orifice.
Clean the dirt / foreign particels in the by-pass piston
orifice or change the piston and turn adjustment 1 out.
Valves are already adjusted and tested. Check electrical operation before changing valve settings. Test that the correct solenoid is energised, by removing nut
and raising solenoid slightly to feel pull.
A
For checking the operation of the solenoids, remove the top nuts. By lifting the coils a few millimeters, the magnetic pull of the coil can be felt. For testing, the
operation of the elevator car can also be controlled by lifting and replacing the coil.
If the coil gets too hot, the coil has to be mounted onto the solenoid and the following adjustments have to be carried out on normal travels from floor to floor.
Standard settings: Adjustment 1 level with flange faces. Adjustment 5 (KV1S & KV2S) level with flange faces.

ropes, the electrical supply to the elevator should automatically be switched off. As the ram comes to a stop, usually after about 60
cm, a limited slack rope condition will occur. The KS Slack Rope Valve avoids the ram being lowered by the opening of the manual
lowering valve which would otherwise cause additional slack rope. The KS Slack Rope Valve prevents the pressure holding up the
ram from being evacuated through the manual lowering valve.
Function
The KS valve is adjusted to a pressure just above the pressure produced by the weight of the ram. When under normal operating
conditions, the weight of the car acts upon the ram through the 1:2 roping, the resulting pressure is sufficient to open the poppet of
the KS valve when the manual lowering H is opened, allowing the car to descend as required. When however the`safeties´ have
operated and only the weight of the ram and sheave block are acting upon the hydraulic system, the resulting pressure is too low
to open the KS valve. The ram and sheave block can not be lowered.
Adjustment
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 energised. 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.

Overheating of Power Units
- System Leakage
Oil temperatures above 55 °C (130° F) should be avoided, otherwise the efficiency of the pump drops considerably and its life is
reduced. Aging of the oil is also accelerated.
Possible causes of overheating:
1. Up levelling too long due to the levelling speed being too slow or the slow down switch being set too low.
2. Machine room ventilation inadequate.
3. The frequency of operation is too high for the normal rate of heat dissipation.
Temporary solution:
As a temporary measure to avoid overheating of the oil resulting in the shut down of the elevator, the down speed can be slowed
to reduce frequency of operation until a permanent solution is installed.
Cooling systems
a. If the degree of overheating is not excessive and it takes for example two to three hours for the oil temperature to rise from 20°
to 55°C (70° to 130° F), it may be sufficient to improve air circulation around the power unit, for example through the installation
of a 0.05 to 0.10 kW ventilator extracting air out of the machine room or through a fan of similar power, blowing air over the
power unit.
b. Should the above be inadequate, depending on the size of the elevator, it will be necessary to install a 10-50 l/min. (3 - 13 gpm)
pump to circulate the hot oil through an air cooled radiator of about 0.1 to 0.2 fan kW. It is also essential that there is sufficient
extraction of warm air out of the machine room or that the cooler is out side of the machine room, for example in the elevator
shaft. The effective cooling power of an air cooled radiator should not to be confused with the power of the fan drive which
normally need only be 0.1 or 0.2 kW. Normally, the effective cooling power of a cooler need only be approximately ¼ of the
main hydraulic elevator motor, in the case of submersible drives.
Cooling systems for the above purpose should be switched into operation when the oil reaches 30° - 35°C (85° - 95° F).
System leakage (re-levelling)
The aim of manufacturers of hydraulic elevator control valves is to produce valves with zero leakage. Due to fine contamination in
the oil perfect sealing between valve parts may not always be achieved, leading to a slow down leak of the elevator car.
It would become unnecessarily expensive to strive for perfect sealing in every valve in operation. Therefore, because code requirements assure a safe relevelling system whether descent of the car is caused by valve leakage or through the cooling of the oil in
the cylinder pressure system, a minor leakage of the control valve can be tolerated.
1. The European Code EN 81-2 require: that the loaded elevator does not leak downwards by more than 10 mm (3/8“) in 10
minutes. This is the standard used to determine if a valve should be serviced for leakage.
2. For practical reasons, a quicker method for judging valve leakage is to close the ball valve in the cylinder line and observe
the gauge showing pressure in the cylinder chamber of the valve. If this pressure falls to zero in less than 20 secs, it may be
necessary to service the valve, depending on the diameter of the main ram and sensitivity of the customer.
3. Down sinking giving the impression of leakage can be due to cooling of the oil.
When the elevator is at rest and the temperature of the oil falls, contraction of the oil in the cylinder and piping causes the car to
sink. This sinking is very slow but overnight without relevelling could amount to as much as half a meter, depending on the temperature drop of the oil and the volume of oil in the cylinder system. The elevator relevelling system, operating normally however,
keeps the car at floor level.
4. In the case of Blain EV valves, see page 10 EV and 16 KV
indicating where valve down leakage can occur.
