PRINCIPLES OF OPERATION
Operation
The Spirit 1700 SII Dental Chair is operated by hydraulic com-
ponents. The chair backrest and truss are actuated by hydraulic
cylinders. Hydraulic flow is provided by a 115V pump (or 230V
on international product). Hydraulic flow is controlled by the
hydraulic control valve directing the hydraulic fluid from the
pump into the cylinders for movement. The Hydraulic Control
Valve can be adjusted to regulate hydraulic flow, reducing the
chair’s speed.
Control Devices
Control of the chair is possible with a multifunction foot switch
and backrest or unit-mounted touchpad. Both options allow
manual positioning of the chair and accessing of auto-positions.
the control system uses low-voltage membrane switches.
Automatic Positioning And Soft Limits
The Spirit 1700 SII Dental Chair has automatic position
programming, meaning it is capable of storing two automatic
positions. (See page 21 for programming procedures.) User
programs are saved and retrieved by using potentiometers
(variable resistors). The chair has a potentiometer on the
backrest and truss sections. The potentiometer tracks the
chair’s movement on geared assemblies that reference off
the chair’s backrest and truss cylinders.
The dental chair extremes of travel are controlled using the
same potentiometers described above. The chair is progra-
mmed at the factory to a series of predetermined soft limits.
Refer to page 20 for factory soft limit settings.
Base Safety Plate
The base safety plate, when activated, will stop the downward movement of the chair base section. This safety feature will prevent any
damage if an object should obstruct the chair’s downward movement.
Note: When a potentiometer or other related component is
replaced it will be necessary to reset the chair’s soft limits.

DIAGNOSTICS CODES & TROUBLESHOOTING
The main control board is equipped with a visual diagnostic display to aid in servicing and troubleshooting the chair. The right and left LED
displays shown below are used to diagnose any operational problem with the chair. The tables below explain individual codes and the
failures they indicate. To diagnose a malfunction on the main control board read the two-digit code displayed and refer to the input/output
status charts.

P/N: 064577 Rev. 01, 12/09/19
Chair must be lowered to its lowest possible position by placing a jumper on 2 pins on the circuit board and lowering chair.
Base Potentiometer Calibration (no voltmeter)
Loosen set screw on large gear.
(Adjust pot position to clear a FF or 00 code.)
Lower base until cantilever is parallel with floor.
Rotate large gear counterclockwise until it stops.
Rotate large gear clockwise 2 teeth.
Tighten set screw.
Potentiometer position and chair position are now synchronized.
Soft limits are the minimum and maximum values of the base and backrest potentiometer. Soft limit values allow the chair to be progra-
mmed to operate within the desired limits of travel. Refer to the illustrations below for soft limit dimensions.
Soft limits must be reset whenever the chair’s potentiometers are disturbed or “not calibrated”. This includes cylinder replacement, pote-
ntiometer replacement and main control board replacement.
• To reset soft limits, remove the pump cover for access to the main control board.
• Place the 2-pin jumper onto both terminals of the optional 8-pin header (shown on page 21).
• Position the chair to a height of 23.5” (see below).
• Push and hold the LEARN button on the foot control (see page 21).
• Press the base up switch on the foot control twice (tap, tap). The board will chirp once to confirm setting of the upper base limit.
Release the LEARN button.
• Lower chair base to measured height of 11”, or 13” for Orbit chairs, and repeat the above procedure.
• Push and hold the LEARN button and press the base-down switch twice. The board will chirp once to confirm the setting of the lower
base limit. Release the LEARN button.
• Position the backrest as shown below, lowering it to its mechanical limit and then raising it two inches. Press and hold the LEARN
button while tapping the backrest down switch twice. The board will chirp once to confirm the setting of the lower backrest limit.
Release the LEARN button.
• Raise the backrest as shown below to its mechanical limit and then lowering it two inches. Press and hold the LEARN button while
tapping the backrest-up switch twice. The board will chirp once to confirm the setting of the backrest limit. Release the LEARN button.
• Reinstall jumper onto a single pin of Option 7 and manually cycle the chair to the soft limit settings, ensuring the new settings have
been accepted.

Although the Nustar SII Dental Chair is preset to access two position. If two positions are desired, the chair will need to be reset. This can
be done by unplugging the chair, removing the jumper from both pins on option seven and reinstalling it on only one pin of option seven.
Power up the chair and it will be able to save and access only two positions.
Configuring main control board for four-position and two-position memory.
To program the chair for two positions, refer to the steps for STORING POSITIONS 1 AND 2.
Option 7: Jumper on both pins
to enable four - positions.
Option 7: Jumper on both pins
to enable two - positions.
Option 8: Bypass / reset programmed
soft limits.
