Base Section 5 – Procedures
(Steer hard right= 3.3 volts… Steered straight= 3.7 volts… Steer hard left= 4.1 volts)
Test between negative and RM 30.
RM 31 - Turret position for direction sensor. 12 volt input through motor controller harness A pin #A9 from limit
switch LS1 on wire 17.
0 volts= Platform over drive axle.
12 volts= Platform over steer axle.
Test between RM 31 and 02 wire.
RM 32 - Tilt sensor input on wire 28. 12V= Level. 0V= Tilted.
Test between RM 32 and 02 wire.
RM 33 - Drive/ Boom function Enable- Negative output through motor controller harness B pin #B1 on wire 259 to
relay 259CR.
Machine stowed and tilted= Boom up, riser up and telescope out functions allowed until limit switches are
activated (LS2, LS3 or LS4). Drive remains active.
Machine elevated and tilted= All boom functions remain active. Drive is cut out.
Test for negative at RM 33 while machine is stowed.
RM 34 - Not used.
RM 35 - Platform Mode input. 12 volt input on wire 7A = Platform control mode.
Test for 12 volts between RM 35 and battery negative while in Platform position.
Left Motor Controller Connector
LM 1 - Enable in- 12 volt input on wire 8B from motor controller harness A pin #A12.
Test between LM 1 and battery negative while activating footswitch or base enable switch.
LM 2 - Not used.
LM 3 - 12 volt input on wire 3D from DC/DC converter.
Test between LM 3 and battery negative with both upper and lower E stop switches activated.
LM 4 - Negative output to left motor brake connector.
Test for 48 volts between brake positive and brake negative. If no voltage found test for continuity between
LM 4 and brake negative at left motor brake connector. Replace if defective.
LM 5 - Negative output to left motor encoder connector.
Test for continuity between LM 5 and encoder negative at left motor encoder connector. Replace if
defective.
LM 6 - Not used.
LM 7 - Charger cutout. 12 volt input through motor controller harness A pin #A23 on wire 60A from charger
interlock relay L1CR.
12 volts= machine operable. 0 volts= machine disabled.
Test for 12 volts between LM 7 and battery negative without charger plugged in.
LM 8 - Not used.
LM 9 - Not used.
LM 10 - E stop return- 48 volt input on wire 3C from motor controller harness A pin #A4.
