Elevator Control Valves

EN ISO 9001

The BLAIN EV4-vvvf program includes the widest range of vvvf solution o ered to the elevator industry for high performance
passenger elevators. Easy to install, EV4‘s are smooth, reliable and precise in operation throughout extreme load and tempera­ture variations with inbuilt overload protection and di erent energy saving modes. The EV4 system uses the control of L1000H
vvvf drive in the up travel, while down travel is managed by the EV4 valve itself. In this way, the EV4-vvvf solution o ers the most
cost-e ective and energy-e cient solution.

¾" EV4 1 ½" & 2" EV4

2 ½" EV4

Description

Available port sizes are ¾", 1 ½", 2" and 2 ½" pipe threads, depending on fl ow. EV4 eliminates high inrush currents and do not require
wye-delta switching. According to customers‘ elevator data, valves are factory adjusted, ready for operation and very simple to readjust
if desired. The L1000H Yaskawa drive combined with feedback systems that are designed to compensate elevator speed fl uctuations
regardless oil temperature and car load conditions.
Caution: The EV4 valve is to be used only together with Yaskawa L1000H inverter and not as standalone control valve.
EV4 valves include the following features essential for e cient installation and trouble free service:

Caution: Please refer to the detailed installation
and set-up procedure of the EV4 handbook and
L1000H technical manual.

The up direction control is done by the Yaskawa L1000H
inverter. The inverter with the help of its software calcu­lates the load in the car, read the current oil temperature
through a temperature sensor and process oil and pump
performance data in order to obtain motor speeds for the
nominal, intermediate, inspection and levelling speeds.

After giving the oil type and elevator data a teach run with
empty car is su cient enough for the inverter to self­learn and confi gure itself fully automatic during the initial
set-up.

Warning: Only qualifi ed personnel should adjust or service the EV4 valve and the L1000H drive. Unauthorised

manipulation may result in injury, loss of life or damage to equipment. Prior to servicing internal parts, ensure that
the electrical controller is switched o , cylinder line is closed and residual pressure in the valve is reduced to zero.

Adjustments DOWN

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.

Nominal Settings: Adjustments 7
ments 6

& 8 turn all the way 'in' (clockwise), then 1.5 turns 'out' (c-clockwise). One fi nal turn in either direction may be necessary.

6. Down Acceleration: When solenoids C and D are energised, the car will accelerate downwards according to the setting of
adjustment 6. 'In' (clockwise) provides a softer down acceleration, 'out' (c-clockwise) a quicker acceleration.

7. Down Speed: With solenoids C and D energised as in 6 above, the full down speed of the car is according to the setting of
adjustment 7. 'In' (clockwise) provides a slower down speed, 'out' (c-clockwise) a faster down speed.

8. Down Deceleration: When solenoid C is de-energised whilst solenoid D remains energised, the car will decelerate according to

the setting of adjustment 8. 'In' (clockwise) provides a softer deceleration, 'out' (c-clockwise) a quicker deceleration.

Attention: Do not close all the way in! Closing adjustment 8 completely (clockwise) may cause the car to fall on the bu ers.

9. Down Levelling: With solenoid C de-energised and solenoid D energised as in 8 above, the car will proceed at its down levelling
speed according to the setting of adjustment 9. 'In' (clockwise) provides a slower, 'out' (c-clockwise) a faster down levelling speed.

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: Solenoids C and D must be de-energised! The KS is adjusted with a 3 mm Allan 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 Manual Lowering H is opened. Should the car not descend, K must be backed o until the car just begins to
descend, then backed o a further half turn to ensure that with cold oil, the car can be lowered as required.

& 9 approx. level with fl ange face. Two turns in either direction may then be necessary. Adjust-

Adjustments pressure relief valve

Valves are already checked for functionality. Check electrical operation before changing inverter settings. Please refer to the EV4

inverter manual for necessary parameter settings.

S Relief Valve: ‚In‘ (clockwise) produces a higher, ‚out‘ (c-clockwise) a lower maximum pressure setting. After turning ‚out‘, open

manual lowering H for an instant.

Important: When testing relief valve, do not close ball valve sharply.
