I
K-22
- Should illuminate when LV guidance attitude reference gets lost.
LV ENGINES 1-5 lights
1
I
K-22
Illuminates yellow when the corresponding engine is operating below it's predeterminated level of thrust. See also Apollo 15 CSM Launch Checklist
LIFT-OFF and NO AUTO ABORT switch-lights
1
I
L-21
LIFT-OFF illuminates white at lift-off and will be extinguished at commencement of first stage staging.

NO AUTO ABORT illuminates red when lift-off illuminates and the EDS switch is turned off.

Pressing the button has no function yet.

CM RCS He DUMP switch
1
K
N-23
- No function yet.
EVENT TIMER RESET DOWN switch
1
L
P-21
RESET sets the event timer to 0 and stops counting. When switched to center position the event timer counts up when running otherwise it counts down.  
EVENT TIMER START STOP switch
1
L
P-22
START starts the event timer, STOP stops it. The event timer is not working before lift-off and is set to 0 and started at lift-off. Up position is spring-loaded to center position.
EVENT TIMER MIN switch
1
L
P-22
Increases or decreases the event timer minutes in tens or units depending on the EVENT TIMER RESET DOWN switch. Spring-loaded to center position.
EVENT TIMER SEC switch
1
L
P-23
Increases or decreases the event timer seconds in tens or units depending on the EVENT TIMER RESET DOWN switch. Spring-loaded to center position.
CRYO PRESS status light
2
A
C-31
Indicates when the pressure of a hydrogen cryogenic tank is below 220 psi or above 270 psi or the pressure of a oxygen cryogenic tank is below 800 psi or above 950 psi.  
CO2 PP HI status light
2
A
C-32
Indicates when CO2 partial pressure in the suit circuit reaches 7.6 mmHg. The light is wrongly labeled with "CO2 PRESS" .
GLYCOL TEMP LOW status light
2
A
C-32
Indicates when the temperature of the radiator outlet of the primary water-glycol coolant loop drops below -30 °F.  
FC 1/2/3 status light
2
A
C-33
Indicates one of the following conditions in the respective fuel cell:
  • H2 flow rate above 0.171 lb/hr
  • O2 flow rate above 1.276 lb/hr
  • Skin temperature below 360 °F or above 475 °F
  • Condenser exhaust temperature below 150 °F or above 175 °F
  • Radiator outlet temperature below - 30 °F
To avoid spurious alarms the temperature limits are weakened during higher time accelerations in the current implementation.
O2 FLOW HIGH status light
2
A
D-34
Indicates when total ECS oxygen flow reaches 1.0 lb/hr for a period of time exceeding 16.5 s. To avoid spurious alarms the limit is weakened during higher time accelerations in the current implementation.
SUIT COMPRESSOR status light
2
A
D-35
Indicates suit compressor differential pressure below 0.22 psi. To avoid spurious alarms the limit is weakened during higher time accelerations in the current implementation.

EDS switch
2
D
M-24
When switched to AUTO, an automatic abort is triggered when the LV thrust level is below 30% between 10s and 100s after liftoff. Should enable/disable the LV auto abort system, details about that are not known at the moment.
