DIP

SWITCH

SETTINGS

J/V-Generation / J-3 / Silhouette / Advantage / aXcs

A DIP switch assembly, which is located at the top center of the main control board under the base cover, is used to set certain functions of the chair’s electronic control package.

— IMPORTANT —Change DIP switches only while the chair

power is disconnected. Once the chair power is reconnected, the main control board will

recognize any changes made.

NOTE: The main control board expects at least one controller attached to the M (main) wiring connec-tor. If there is no controller attached to either the M or A (auxiliary) connectors, the board will generate a service LED code that indicates one of the controllers needs checking.

Technical Manual



BEEP

CODES

The chair’s electronic control package is designed to sound specific beep code signals to alert the operator of certain con-trol conditions. Understanding the beep codes enables the operator to isolate the condition and take appropriate action. Base conditions are indicated by a constant short beep; back conditions by two constant short beeps; and seat condi-tions by three constant short beeps. Three short beeps indicate a function is not available when its button is pressed. A constant fast beep that sounds only when a function is moved indicates a potentiometer condition.The beep code signal chart below lists the audible sound, control condition and service action to take. The codes are also prioritized letting the user know that conditions listed above the indicated code are normal.

LED

CODES

There is a three-light LED assembly on the main control board that indicates each power up mode and various service conditions the chair may encounter. The LED assembly is located at the top center of the main control board (left of the DIP switch assembly) under the base cover. The power-up codes are described in the table below. A service condition LED code chart appears on the next page. The LED codes are prioritized from top to bottom let-ting the user know the conditions listed above the indicated code are normal.

J/V-Generation™ Chair

Control Valve Speed Adjustment

Tools Required:

• Phillips Screwdriver• Flat-head Screwdriver• Safety Glasses

1. Raise the chair base to its full UP position.

2. Take off the base (pump) cover by removingand retaining the four Phillips-head screwsthat attach it to the base plate.

NOTE: Adjustable flow control valves, located in thehydraulic control valve, are used to set the chair functionspeeds. The base and back cylinders are single actingcylinders. They have two flow control valves each (UPand DOWN) to control their speeds. The seat cylinderis double acting and requires four flow adjustmentvalves. Valves marked (PWR) are for incomingfluid. Valves marked (RET) are for outgoingfluid. The (RET) valves are adjusted first to set agross speed and the (PWR) valves are used for finetuning the speeds. Once the (RET) flows have been set,they should not be readjusted.

Function times given are based on a 200-pound personsitting in the chair.

a. Move the base up and down adjusting theflow controls until it takes 12 seconds forthe base to move either up or down thefull travel.

b. Move the back up and down adjusting theflow controls until it takes 12 seconds forthe back to move either up or down thefull travel.

Section VII User Service Information

— WARNING —Wear safety glasses while adjusting the valve.Flow control valves should not be turned outfarther than the top of their heads being evenwith the valve body surface. Adjustment ofthe flow control valves beyond the valve bodysurface may result in oil leakage with uncon-trolled motion of the chair and the possibilityof a valve being ejected from the valve body.
