Unit Operation
SR-3 Truck HMI Controller
The SR-3 Standard Truck HMI (Human/Machine Interface)
Control Panel is supplied as standard equipment on SR-3
Single Temperature Truck applications. It is used to operate the
unit and display some unit information. The SR-3 Standard
Truck HMI Control Panel communicates with the base
controller via the CAN (Controller Area Network) bus. It is
connected to the base controller via CAN Connector J14 on the
interface board. The SR-3 Standard Truck HMI Control Panel
is typically located in the vehicle driver's compartment. It may
be located in the truck dashboard using a DIN mounting ring or
under the dashboard using an under dash mounting kit.

• The SR-3 Standard Truck HMI Control Panel consists of a
display and nine touch-sensitive keys.
• The display is capable of showing numbers and lighting
several icons. It does not display text, thereby making it
suitable for use with any language.
• Amber indicator LED's are located next to each of the four
function keys below the display. The LED will light when
that function is active.
• A red indicator LED is located between the ON Key and
OFF Key. This indicator will glow if Alarm Code 91
Check Electric Ready Input occurs. It will also glow if a
15 pin Thermo King data cable is connected to the serial
port on the back of the controller (DPD).
