IMPORTANT SAFEGUARDS

Read Instructions: All Safety, installation, and setup instructions should be read before installing or operating the EMV10 Electronic Motor Valve.

Failure to follow the installation and setup instruction may result in unsatisfactory performance, equipment damage, or physical injury.

1. Service: There are no user serviceable parts contained herein. Refer all service to qualified service personnel only.

2. Risk of Electrical Shock: Do not remove the valve cover except when making adjustments or servicing the valve. Always turn off all electrical
power sources before servicing any mechanical part or assembly. Do not place metal objects in contact with the energized Electronic Control
Board at any time.

3. EMV10 Power Sources: The EMV10 Electronic Motor Valve uses multiple electrical power sources. Hazardous voltages may be present
even if one source to the EMV10 is secured. Verify all voltage sources to the EMV10 are secured before making repairs.

4. Wiring: All wiring should be routed in such a way that it is not likely to be pulled, pinched, stepped on, have objects placed on it, or damaged
in any way.

5. Retain User Manual: The user manual should be retained for future reference.

INTRODUCTION AND FEATURES

The Maxton EMV10 Electronic Motor Valve was designed to meet a growing demand for low use limited access (LULA), handicapped and residential
hydraulic elevator applications. The EMV10 combines hydraulic and electronic control to provide excellent ride quality. The EMV10 has all the features
found in a commercial hydraulic control valves plus electronic safety control and adjustments allowing quick set up and easy problem analysis.

FEATURES

• Quick set up and less field adjustments required.

• Built in pressure and viscosity compensation.

• Ride performance is maintained from empty to fully loaded condition.

• Acceleration and deceleration are independent of load and oil viscosity.

• Regulated contract down speed, up leveling speed and down leveling speed.

• Stabilized leveling speed is achieved in a very short distance.

SLOWDOWN DISTANCE

\\SERVER\Current EMV10 documentation

Installer to provide U, UL, D, and DL signals from main elevator controller to VCB (Valve Control Board).

CONTROL SIGNAL SEQUENCE

• UL: For up travel, turn on at pump start, turn off to stop. With UL signal on and pump running, car moves up at leveling speed. For “soft stop”

pump should run about one half second after UL signal is turned off.

• U: Turn on with UL to run up at contract speed. Turn off at slowdown distance from floor.

• DL: Turn on to move downward at leveling speed. Turn off to stop.

• D: Turn on with DL signal to run down at contract speed. Turn off at slowdown distance above floor.

1/2 to 1 second after US signal cut off
