EXTERNAL HYDRAULIC PUMP Switch/Indicator 1A4A4S6/S14/DS7
Starts AC electric motor in wheel well which drives hydraulic pump. HYD PUMP ON indicator
lights (blue) when AC motor is turned on. POWER MODE switch (40) must be in EXT position
to enable this system.
RETURN LINE Indicator 1A4A4DS21
Hydraulic filter replacement REPL FILTER indicator lights (red) when filter in hydraulic
system supply line needs to be replaced.
The hydraulic filter replacement REPL FILTER indicator may light during cold weather
operation. Do not replace hydraulic filter element unless indicator stays on after system has
warmed up for at least ten minutes.
REFRIGERANT PRESSURE Indicators 1A4A4DS5/DS6
Indicator lights (red) when either the HIGH LOW R22 refrigerant pressure limit is exceeded.
HEATER STAGE 2 Power On Switch/Indicator 1A4A4S3/DS2
Selects heat stage 2 when ESS MODE selector switch is in HEAT position. 3.0 kW HTR ON
indicator lights (green) when switch is pressed. The 10 kW TQG supplied with the CBPS will
not support this heat setting in external power mode. The 10 kW TQG and ECV used together
will support this heat stage.
HEATER STAGE 1 Power On Switch/Indicator 1A4A4S2/DS1
Selects heat stage 1 when ESS MODE selector switch is in the HEAT position. 2.5 kW HTR
ON indicator lights (green) when the switch is pressed.

175F or whenever rib fan has been running for ten minutes.
RIB CYCLE Indicator 1A4A4DS31
RIB FAN EXTENDED OPERATION lights (red) when rib fan has been running for ten
minutes. An internal switch causes an audible alarm (36) to sound.
HYD LEVEL/TEMP ALARM 1A4A4LS3
Mutable audible alarm whenever the hydraulic fluid level is too low.
Unmutable audible alarm whenever hydraulic fluid temperature reaches 230F.
TEMPERATURE Control 1A4A4R1
Sets CBPS temperature over a range of 60F to 90F. Used during static mode.
POWER MODE switch 1A4A4S1
Selects CBPS power source. EXT position selects HMT mounted TQG or other external power.
INT position selects ECV power.
NBC FILTER DIFFERENTIAL PRESSURE Gage 1A4A4PG3
Indicates amount of air flow passing through NBC filters located in ECU. Normal NBC
pressure is 6 iwg. A reading of 9 iwg indicates NBC filters are dirty and need to be replaced. A
reading of 3 to 5 iwg is normal when not in NBC mode.
