Overview:

The new version 1212P-2502 (CURTIS P/N 17722705S) is the updated version of 1212P-2501 (CURTIS P/N 17722702) and old version 1212P-2502 (CURTIS P/N 17722705), designed for use in low power DME applications such as micro-scooters, mini-scooters, foldable scooters, and low-end personal mobility vehicles. Although it is optimized for use on modern 3-wheel and 4-wheel mobility aid scooters, its programmable options also allow it to be used on any low power permanent magnet motor application.

The 1212P-2502 controller is fully programmable, via the CURTIS Model 1313-4331 Handheld Programmer, 1314 PC Programming Station, or DALA handheld programmer (compatible with CURTIS 1313-4331). This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

Configuration of controller assembly:

• Controller model: 1212P-2502
• Throttle model: ET-126 MCU
• Power On switch: key switch JK 802
• Working voltage: 24V DC
• Motor type: brush type permanent magnet drive motor
  • Used as traction motor (continuous load): power rate ≤ 500 Watts
  • Used as hydraulic pump driving motor (intermittent load): power rate ≤ 1200 Watts
• Electromagnetic brake option:
  • Without EM brake
  • With EM brake (need more information for controller setting)
    • Delay: range 0-1 second. Sets the length of delay between when zero speed is commanded and the electromagnetic brake is engaged.
    • Fault Check: options On / Off. Enables / disables the fault detection on the EM brake.
    • Hold Voltage: range 10–24V DC. A high initial voltage is applied to the brake coil when the brake is first released. After approximately 1 second, this peak voltage drops to the programmed Hold Voltage. The parameter should be set high enough to hold the brake released under all the shock and vibration conditions the vehicle will be subjected to.
    • Brake Light: options: On / Off. When set to On, the horn output (J1 Pin 3) will act as a brake light driver. The brake light must be driven by a relay, as shown in Figure 8. The brake light will be turned on when the throttle is returned to neutral and will remain on for about 2 seconds after the EM brake is engaged. When the horn output is used as a brake light driver, Fault Beep (see Horn menu) should be programmed Off. When Brake Light is set to Off, the horn output acts as a horn driver.
• Applications: pallet stacker, pallet truck, tractor, scooter / moped / trike, etc.

• B+, B- logic pin current (max.): 9 A (pins 7 and 13 on 14-pin connector)
• KSI input current (typical): 80 mA
• Logic input current (typical): 1 mA
• Horn output current (max.): 15 mA
• BDI output voltage, resistance (max.): 0–5 V, 10 kΩ

• Undervoltage cutoff: 14 V
• Overvoltage cutoff: 34 V
• Throttle Type: By default, the Throttle Type of controller 1212P-2502 is set as Type 7 (7 = single-ended; neutral when wiper ≤ PotLow). The 1212P-2502 controller can accept inputs from both 5kΩ, 3-wire pot throttles and voltage throttles. Set the throttle type parameter to match the throttle used in your application.
  • 5kΩ, 3-wire pot throttles:
    • 0 = wigwag
    • 1 = inverted wigwag
    • 2 = single-ended; neutral when wiper at PotLow
    • 3 = inverted single-ended; neutral when wiper at PotHigh
    • 4 = unipolar
  • Voltage throttles
  • 5 = wigwag
  • 6 = inverted wigwag
  • 7 = single-ended; neutral when wiper ≤ PotLow
  • 8 = inverted single-ended voltage; neutral when wiper ≥ PotHigh
  • 9 = unipolar
• Dimensions: W72xL131xH39 mm
• Net Weight: 0.3 kg
• Regulatory compliance: Designed to meet EN 12184, EN 55022, IEC 61000-6-2 & -4-6, and ISO 7176; FDA documentation filed; TÜV Certification pending
• Operating ambient temperature range: -25°C to 50°C
• Storage ambient temperature range: -40°C to 65°C
• Package environmental rating: ISTA 2A; electronics sealed to IPX5

Features Include:

• Advanced speed regulation maintains precise speed over varied terrain, obstacles, curbs, and ramps
• Linear cutback of current ensures smooth control, with no sudden loss of power during undervoltage or overtemperature
• Optional speed limit potentiometer provides direct and linear control of the maximum vehicle speed
• Proprietary algorithms help prevent gearbox wear while providing smooth starts and reversals
• The vehicle is brought to a complete stop before the electromagnetic brake is applied, ensuring safe and secure stops under all conditions
• Charger inhibit input prevents driving while charger is attached
• Key Off Decel function ensures a smooth “brake to stop” when the key is turned off while driving or when a fault occurs that requires the vehicle to stop
• Anti-Rollback/Roll-forward function provides smooth and safe vehicle control on hills and ramps
• Internal main contactor provides secure power-off
• Boost current gives a brief boost of current greatly improving transient loads such as starting on a hill, crossing thresholds, etc.
• Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer, 1314 PC Programming Station, or DALA handheld programmer (compatible with CURTIS 1313-4331).
