Warning: Only qualified personell should adjust or service valves.

Unauthorised manipulation may result in injury,


loss of life or damage to equipment. Prior to servicing internal parts, ensure that the electrical power is switched off and residual
pressure in the valve is reduced to zero.
Adjustments UP
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 slighty to feel pull.
Nominal Settings: Adjustments 1 & 4 approx. level with flange faces. Up to two turns in either direction may then be necessary. Adjustments 2, 3
& 5 all the way 'in' (clockwise) then 2 & 5 two turns 'out' (c-clockwise), 3 three turns out. A small final adjustment may be necessary.

EV 0 1. By Pass: When the pump is started, the unloaded car should remain stationary at the floor for a period of 1 to 2 seconds
before starting upwards. The length of this delay is determined by the setting of adjustment 1. 'In' (clockwise) shortens
the delay, 'out' (c-clockwise) lengthens the delay.
2. Up Acceleration: With the pump running, the car will accelerate according to the setting of adjustment 2. 'In' (clockwise)
provides a softer acceleration, 'out' (c-clockwise) a quicker acceleration.
Up Stop: The pump-motor is de-energised. There is no adjustment.
Alternative Up Stop with Over-travel: The motor is de-energised at floor level. Through the flywheelaction of the pump-
motor drive the car will travel to just above floor level. In overtravelling the floor, down levelling solenoid D is energised,
lowering the car smoothly back down to floor level where D is de-energised.
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.

EV 1 1. By Pass: When the pump is started and solenoid A energised, the unloaded car should remain stationary at the floor for
a period of 1 to 2 seconds before starting upwards. The length of this delay is determined by the setting of adjustment
1. 'In' (clockwise) shortens the delay, 'out' (c-clockwise) lengthens the delay.
2. Up Acceleration: With the pump running and solenoid A energised as in 1, the car will accelerate according to the setting
of adjustment 2. 'In' (clockwise) provides a softer acceleration, 'out' (c-clockwise) a quicker acceleration.
5. Up Stop: At floor level, solenoid A is de-energised. Through a time relay the pump should run approx. ½ second longer
to allow the car to stop smoothly by valve operation according to the setting of adjustment 5. 'In' (clockwise) provides a
softer stop, 'out' (c-clockwise) a quicker stop.
Alternative Up Stop: At relatively higher speeds, the car will travel to just above floor level. In overtravelling the floor,
down levelling solenoid D is energised, lowering the car smoothly back down to floor level where D is de-energised.
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.

EV 10 1. By Pass: When the pump is started and solenoid B energised, the unloaded car should remain stationary at the floor for
a period of 1 to 2 seconds before starting upwards. The length of this delay is determined by the setting of adjustment
1. 'In' (clockwise) shortens the delay, 'out' (c-clockwise) lengthens the delay.
2. Up Acceleration: With the pump running and solenoid B energised as in 1, the car will accelerate according to the setting
of adjustment 2. 'In' (clockwise) provides a softer acceleration, 'out' (c-clockwise) a quicker acceleration.
3. Up Deceleration: When solenoid B is de-energised, the car will decelerate according to the setting of adjustment 3. 'In'
(clockwise) provides a softer deceleration, 'out' (c-clockwise) a quicker deceleration.
4. Up Levelling: With solenoid B de-energised as in 3, the car will proceed at its levelling speed according to the setting
of adjustment 4. 'In' (clockwise) provides a slower, 'out' (c-clockwise) a faster up levelling.
Up stop: The pump-motor is de-energised. There is no adjustment.
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.

EV 100 1. By Pass: When the pump is started, and solenoids A and B energised, the unloaded car should remain stationary at
the floor for a period of 1 to 2 seconds before starting upwards. The length of this delay is determined by the setting of
adjustment 1. 'In' (clockwise) shortens the delay, 'out' (c-clockwise) lengthens the delay.
2. Up Acceleration: With the pump running and solenoids A and B energised as in 1, the car will accelerate according to
the setting of adjustment 2. 'In' (clockwise) provides a softer acceleration, 'out' (c-clockwise) a quicker acceleration.
3. Up Deceleration: When solenoid B is de-energised, whilst solenoid A remains energised, the car will decelerate according
to the setting of adjustment 3. 'In' (clockwise) provides a softer deceleration, 'out' (c-clockwise) a quicker deceleration.
4. Up Levelling: With solenoid A energised and solenoid B de-energised as in 3., the car will proceed at its levelling speed
according to the setting of adjustment 4. 'In' (clockwise) provides a slower, 'out' (c-clockwise) a faster up levelling.
5. Up Stop: At floor level, solenoid A is de-energised with solenoid B remaining de-energised. Through a time relay the
pump should run approx. ½ second longer to allow the car to stop smoothly by valve operation according to the setting
of adjustment 5. 'In' (clockwise) provides a softer stop, 'out' (c-clockwise) a quicker stop.
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.

Warning: Only qualified personnel should adjust or service valves. 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
off 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 & 9 approx. level with flange face. Two turns in either direction may then be necessary. Adjustments
6 & 8 turn all the way 'in' (clockwise), then three turns 'out' (c-clockwise). One final 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 buffers.
9. Down Levelling: With solenoid C de-energised and solenoid D energised as in 8 above, the car will proceed at its down level-
ling 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 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.
