HOURMETER: ELECTRIC STANDBY (Optional).
The electric standby hourmeter records the total hours of unit operation
on electric standby power.
The electric hourmeter function is built into the TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 controller menu displays.
DIGITAL (OR DIAL) THERMOMETER.
A thermometer indicates the temperature of the air returning to the evaporator
from the cargo area.
The digital thermometer function is built into the TG-V, TG-VI, MT µP-IV, µP-V, µP-VI, SR-2 and SR-3 controller menu
displays.
CONTROLLER LCD DISPLAY.
The LCD display normally shows the setpoint/return air temperature. Some controllers also
display a symbol to indicate air temperature, operating mode or alarm(s).
TG-VI controller symbols:
• Setpoint Symbol
• CYCLE-SENTRY Symbol
• Alarm Symbol
• Electric Symbol
• Cool Symbol
• Heat Symbol
• Defrost Symbol
MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 controller symbols:
• Return Air Symbol
• Discharge Air Symbol
• Setpoint Symbol
• CYCLE-SENTRY Symbol
• Alarm Symbol
• Modulation Symbol
• In-range Symbol

• Zone 3 Symbol (Multi-Temp MT µP-IV)
DATA INTERFACE.
A serial port on the front of the MT µP-IV, µP-V, , SR-2 , SR-3 and µP-VI controllers can be connected
to a computer with Thermo King Wintrac software to download data.
OIL PRESSURE GAUGE.
The oil pressure gauge indicates engine oil pressure. Engine oil pressure should rise immediately
on starting. A low pressure switch will open the reset switch and stop the engine if oil pressure becomes too low for 30 to 50
seconds.
The oil pressure gauge function is built into the TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 controller menu displays.
WATER (COOLANT) TEMPERATURE GAUGE (Optional).
The engine coolant temperature gauge indicates
the temperature of the coolant in the engine block.
The coolant temperature gauge function is built into the TG-VI, MT µP-IV, µP-V, µP-VI and controller menu displays.
RECEIVER TANK SIGHT GLASS.
Use the receiver tank sight glass to check the refrigerant charge. The sight glass also
indicates the moisture content of the refrigerant.
COMPRESSOR OIL SIGHT GLASS.
The compressor oil sight glass indicates the level of compressor oil in the compressor
sump.
REMOTE LIGHT INDICATORS (Optional).
A remote indicator light box can be mounted on the front of the trailer so they
are visible in the driver’s rear view mirror.
AIR RESTRICTION INDICATOR.
An air restriction indicator attaches to the air intake elbow (SL and SLe only).Visually
inspect the restriction indicator periodically to ensure the air filter is not restricted. Service the air filter when the air filter
indicator reads 635 mm (25 in.) H
2
O vacuum. Press the button on the bottom of the indicator to reset it after servicing the air filter.
