1243G2

Purpose

Regenerative Braking

Yes

Yes

Increases battery life allowing the vehicle to operate longer with just a single charge while preventing issues such as motor heating and brush wear

Ramp Restraint

Yes

Yes

Vehicle movement is restricted when set in neutral

Load Compensation

Yes

Yes

Enhanced loaded and unloaded regulation of speed

MultiMode

Yes

Yes

User-select feature offering four operating personalities and the top speed of the vehicle is controlled

Emergency Reverse

Yes

Yes

Stops the advancing vehicle swiftly to allow a smooth change in direction (reverse)

Programmable Static Return to Off and High Pedal Disable

Yes

Yes

SRO: Allows a safe start by requiring the forward and reverse selector to be returned to a neutral position before allowing an output

HPD: Allows a safe start by monitoring the status of the throttle. If the vehicle is started with an applied throttle, this feature disables it from operating until the throttle is returned to the neutral position

Interlock Braking

No

Yes

Reduces wear on EM brake and allows meeting more braking requirements

Maintenance Monitor

No

Yes

Responds with pre-programmed operating and drive hours of the OEM

Hour meter

1

2

1243: Utilizes one hour meter
1243 G2: one KSI-on hour and one traction hour

Internal BDI Calculation

No

Yes

The calculation is done within a controller

Overtemperature Cutback

No

Yes

Once overheated, the maximum speed is reduced.

Diagnostic Checks

No

Yes

Checks for open and shorted faults

EM Brake PWM

No

Yes

Allows modulation of auxiliary driver output

4 Throttle Types

No

Yes

The 1243G2 models are available in 4 throttle types

Active Precharge

No

Yes

The life of the main contactor is prolonged with a capacitor bank

Two Fault Outputs

Yes

Yes

On a display mounted remotely, the diagnostics are displayed
