Sub frame to deck lock unlocked.
(Sub frame to deck lock proximity switch on.)
9.
LHS cab control mode select switch in MRP position.

MRP palm switch pressed.
12.
Outrigger palm switch released.
During elevation cylinder operations, the engine will operate at low idle when the MRP elevation is less than 5
degrees (5 degree elevation proximity switch on). High idle operation occurs, when MRP elevation is greater than
5 degrees (5 degree elevation proximity switch off), ADU/TL cables are connected, and both elevation cylinder
locks are closed. The elevation cylinder operation cannot be performed unless an MRP is loaded on the THAAD
carrier system.
The following checks are required during THAAD Launcher System troubleshooting:
g.
Resistance Checks.
CAUTION
Use proper sized test leads and ensure care is used when checking for resistance,
continuity, or voltage at connectors or damage to equipment may result.
1.
Set the multimeter function/range switch to the desired ohm position.
If the magnitude of the resistance
is not known, set the switch to the highest range, then reduce range until a satisfactory reading is
obtained.
NOTE
Some meters show “l+m”, or simply “l” when function/range switch is set to an ohm
position.
2.
Connect red test lead to volt-ohm input connector and black lead to COM connector on multimeter.
When the test leads are separated or measuring out-of-range resistance, the digital display will indicate
“OL” (Over Load).
3.
If the circuit being measured is connected to power, turn engine start switch OFF (
4.
Connect test leads to the circuit being measured.
When measuring high resistance be careful not to
contact adjacent point, even if they are insulated. Some insulators have a relatively low insulation
resistance which can effect the resulting measurement.
5.
Read the resistance value on the digital display.
6.
If your meter does not work in this manner, follow manufacturer’s instructions for the device being used.
h.
Continuity Checks.
1.
Set the multimeter function/range switch to any ohm range.
