By default, the controller J5 terminal is not activated. If you want to activate the J5 terminal for using the Rev Input / Main
Driver functions, please see the page 7 and 8 of 1204M / 1205M / 1221M controller manual (PDF format).

* Easy to install (1221M Controller Assemblage Installation Instruction (PDF format))
* Reinforced carton package, safe for international delivery
* Assemblage Net Weight: 13.4 kg
* Package Weight: 15.8 kg (including the foot pedal throttle)
Controller features also include:
* High-frequency switching and ultra-low voltage drops provide high efficiency and silent operation.
* Simple mounting and wiring with push-on connectors for control signals and plated solid copper buses for power connections.
* The controller assemblage includes a 2-wire 0-5kΩ potentiometer throttle EFP-001 (controller setting: Throttle Type = "0")
(Multiple throttle types can be used with 1221M-6701 controller. If you want to use a throttle type of different type than type
"0", for example a 0-5V voltage throttle, please contact us.)
* Throttle fault protection circuitry disables controller if throttle wires become open.
* High pedal disable feature prevents controller operation if key is turned on while throttle is applied.
* Plug braking diode internal to controller.
* Thermal protection and compensation circuit provides constant current limit over operating range and during under/over
temperature cutback; no sudden loss of power under any thermal conditions.
* Undervoltage cutback function protects against low battery voltage, including low voltage caused by external loads.
* Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
* Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
