Sabertooth 2x5.pdf - Dimension Engineering

Status and Error LEDsSabertooth 2x5 has two indicator LEDs.The blue LED is used to communicate variousinformation about the current state. In mostcases Status1 acts as a power indicator. In R/Cmode, it glows dimly if there is no RC linkpresent and brightly if there is an RC link. Inlithium mode, the blue LED will blink out thenumber of lithium cells detected.The red LED illuminates if the Sabertooth hasStatus LED ondetected a problem. It will light if the driver hasshut down due to a depleted battery or due to overheating or overcurrent. If you are using a NiCdor NiMH battery, and commanding an acceleration causes the motor to jerk and the Error LED toflash on and off, the battery is depleted.Mounting your Sabertooth 2x5The Sabertooth is supplied with two mounting holes. Thesecan be used to attach it to your robot. The centers of themounting holes form a 1.25” x 1.5” rectangle. The holesare .09” inches in diameter. The proper size screw is a 2-56round head machine or wood screw. two 1/2” long machinescrews and nuts are included.If your robot or device is constructed from insulatingmaterials such as wood or plastic and you are runnin, itmay be necessary to mount the Sabertooth on standoffs toallow air to circulate. This is shown in Figure 2.3If your robot or device is constructed from metal, it isusually better to attach the bottom heat spreader of theSabertooth directly to the frame, without standoffs. Thiswill allow your frame to act as a heat sink and will causethe Sabertooth to run cooler. This is shown in Figure 2.4Figure 2.3: Mounted to a woodframe using standoffsFigure 2.4: Mounted directly to ametal frame
