STAIR CLIMBER SOLIDSTATE CONTROLLER
The Stair Climber Solid State Controller is a fully solid state Pulse Width Modulated (PWM) controller.
Its advanced microprocessor based control implements a state-of the-art power MOSFET motor drive.
Advanced features provide improved functionality, smoother operation, reduced mechanical stress,
and protects against abuse and system faults.
ADVANTAGES
 Reduced peak current reduces power loss in batteries, motor, and cabling.
 Reduced peak current reduces battery stress, increased service life.
 Reduced peak torque reduces mechanical stress, increasing service life of
 Smooth operation "feel" by controlled acceleration and deceleration (motor voltage ramp-up and ramp-
down) eliminating jerkiness.
 Automatically slows speed with heavy loads, improving control and safety.
 Overload protection shuts off if lift load is too heavy.
 Protects batteries by limiting minimum loaded voltage to 8.5 volts.
 Internal protections for many types of internal and external faults.
 Protects controller by inhibiting operation if battery voltage is to high.
 Detects battery+ or battery- short to frame and inhibits motor operation.
 Limits continuous operation to <30 seconds. Control wiring fault protection.
 Alerts to low or excess control heating (from over-use).
 Alerts to overload or excess continuous run time (control fault).
 Alerts to battery+ or battery- short to frame.
 Alerts to internal controller faults.
 Low standby power of less than 20mA.

FAULT ALERTS
Faults are indicated by a buzzer producing a series of beeps to indictate various faults as follows:
One Beep - Overload condition (too much weight on Unit) - Reduce Load
- Maximum run time (25-30sec.) exceeded - Release and re-apply switch
Two Beeps - Low Battery - Recharge Battery
Three Beeps - Battery+ or Battery- shorted to frame. HALT USE AND RETURN FOR REPAIR
System Fault - FAULTY UNIT -HALT USE AND RETURN FOR REPAIR
Four Beeps - Overheating due to excessive use (many minutes) - Allow five minutes to cool
