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 the gear train and motor.
- 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 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 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- 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
