K17
By-passrelayfortheboomraising
Passesbytheoutriggerlimit-switchesastheby-passbuttonS26andthebutton1onthe
joystick are depressed. Enables lifting of the boom to the horizontal plane as the drive function
is operational.
K18
Auxiliary relay for chassis
Switches over the control voltage to the changeover valve 5A as one of the movements on
chassis is activated. The relay does not draw until the combustion engine revolutions have
increased to the required level.
K19
“Telescope in” relay
Switches on the voltage to the “telescope in” valve 6 as the “telescope in” button S30 or S31 is
depressed.
K24
Auxiliary relay for emergency descent
Draws as the emergency descent button S11 or S13 is depressed.
Switches on the voltage to the emergency descent unit solenoid and the emergency descent
valves 9, 10 and 11.
K40
Changeover relay for the control voltage
SwitchesoverthecontrolvoltagetothepowersupplyunitastheAC-feedisplugged.
K41
Auxiliary relay for main relay
Switches off the voltage from the running relay K9 as the main relay switches off the voltage
from the device.
K42
Slowing relay for automatic levelling
As the automatic levelling is used the relay switches on the throttle valve, which reduces the
lowering speed of the support outriggers as the limit switches on the outriggers close.
SR2
Safety relay for monitoring the outrigger operations.
Thesafetyrelayresetsassoonasalloutriggersafetylimitswitches(RK11,RK12,RK13and
RK14)haveclosed.Afterthatitispossibletooperatetheboom.
SR3
Safety relay for monitoring the overloading of the boom.
Safetylimit-switchRK5controlstheoperationofthesafetyrelay.
Overloading of the boom: The SR3 is disconnected and the feed current for the RK4 is
switched off. The safety relay is automatically reset upon return to the normal outreach range.
The delay adjusted with the capacitors affects the tripping moment of the SR3.
If the RK5 fails: The SR3 is disconnected and the feed current for the RK4 is switched off.
The safety relay is not automatically reset but the due operation of the electric equipment must
be checked.
The delay adjusted with the capacitors affects the tripping moment of the SR3.
SR4
EMERGENCY STOP safety relay
The safety relay will disengage as the EMERGENCY STOP button is depressed. The safety
relayswitchesofftheenginesandtheAC-feed.
H2
Signal light.
Signal light for battery recharging, the signal light will go out as the battery is being charged.
F1
Main fuse 200A.
F2

F3
Emergencydescent10A(PK).
F4
Boomvalves10A(PK).
F5
Safety/startcircuit10(PK).
