FACTORY SETTING: All valves are factory tested and set to the job specifications provided. Factory settings should only be changed if accurate car
speed information is available to the technician.

NORMAL OPERATION MODE: Make sure all connectors are plugged in to the VCB (Valve Control Board). The green “POWER” indicator is on and
there is no errors listed on the LCD display. These conditions indicate normal valve operation.

PRESSURE RELIEF ADJUSTMENT:

THE INFORMATION PRESENTED HEREIN IS FOR USE BY SKILLED HYDRAULIC ELEVATOR PROFESSIONALS

• Land car in pit and install pressure gauge in port “B”.

• Register an up call with a fully loaded car, making note of pressure gauge reading.

• Cancel the up call.

• Close the manual shut off valve to the jack.

• Set the relief adjuster to the minimum pressure position. To do this turn the relief adjuster screw fully CW until seated. Then turn CCW 3 full turns.

• Register an up call, observe pressure gauge and turn the relief adjuster CW to increase the pressure gage reading. The final setting should be in

accordance with state and local code requirements.

• Cancel the up call.

• Snugly tighten the relief adjuster nut.

• Register an up call to verify the pressure relief setting.

• Cancel the up call.

• Open the manual shut off valve to the jack.

VALVE SET UP:

• Register up and down calls to verify FLOW (high speed), leveling speed, acceleration, deceleration and stop rates.

• If necessary, use the MODE/ENTER button to navigate to the ride quality setting to select different ride quality (rate). Setting “0” (factory default)

provides the softest ride quality (rate), setting “9” provides the hardest ride quality (rate).

MANUAL LOWERING (ML):

• ML is Twist style located on the right side of the valve.

• Turn ML OUT (CCW) to lower car when necessary. Manual lowering speed may vary with system pressure and jack size.

PROCEDURE FOR SETTING OVERSPEED FLOW WITH 11 AND 12 GPM WORKING FLOW:

• After completely setting up the valve including the down flow. With car at the bottom floor, turn the Relief (R) adjuster out (CCW) to stop.

• Make an up call. Car should not move. Turn the Relief adjuster slowly IN (CW) until the car moves then one more turn IN. Car should make

normal up run and stop at the upper floor.

• Turn the Relief adjuster OUT (CCW) one turn. Make a down call. Car should be running down at speed faster than normal down run. Check car

speed if it complies with the Codes, 110 to 140 % of normal down high speed. If not, turn the Relief adjuster OUT (CCW) for faster or IN (CW) for
slower down high speed. Note the number of turns in this step.

• If an up run is needed, turn the Relief adjuster IN (CW) the same number of turn in Step 3.

• When the down high speed for overspeed condition is obtained, set the overspeed valve (or governor) as required.

ERROR HISTORY

\\SERVER\Current EMV10 documentation

The valve controller program incorporates self diagnostic routines designed to identify conditions that can result in
incorrect or abnormal valve operation. The diagnostic routines have the ability to auto-correct most conditions that may be
encountered.

Error History:
If an error condition occurs the VCB will momentarily stop car movement, interrupt the pump operation and display an
error. If possible clear the cause of the condition and automatically return to normal operation. If experien ci ng large
numbers of error conditions, check the cables for loose connections and proper power to the VCB. To determine if an
error condition has occurred navigate to the Advanced Menu where there is a view history mode. This mode once entered
will display a number of errors recorded up to ten and then display those errors automatically at a three second interval.

Erase Error History:

To erase error history, navigate to the Delete History in the Advanced Menu. Select yes and there will be a confirmation
screen notifying that the operation is complete.

Note 2: For proper operation the elevator pump operation must be interrupted under various conditions.
Therefore be sure to utilize the PUMP DISABLE CIRCUITS in the valve installation as described on pg. 5
