K17: CENTRE POSITION ACTIVATION OF THE JOYSTICK
Switches off the voltage from the joysticks´s micro-switches if the dead-man-switch DMK
has not been pressed while the joystick is in the centre position.
K18: CONTROL RELAY FOR ADDITIONAL MOVEMENT SPEED RESISTORS
The relay is used for changing the Propo-card control voltage over to the adjustable resistor of
the boom/platform levelling.
As the relay is active the control voltage is supplied through the TR10 resistor (movement
speed of the boom from the chassis control panel)
When the relay is not active, the control voltage is supplied via the resistor TR9 (levelling of
the platform)
Control circuit fuse F9 1,6A (Platform control panel) and F4 10A (Chassis control panel).
K19: Change-over relay for control voltage of the Propo-card.
As the relay is active the control voltage to the Propo-card is supplied via additional resistors.
As the relay is not active the control voltage is supplied to the joystick by means of which the
control voltage is adjusted to desired value with the help of adjustable resistors inside the
joystick.
Control circuit fuse F9 1,6A (Platform control panel) and F4 10A (Chassis control panel).
K20: FUNCTION RELAY FOR OUTREACH LIMIT SWITCH RK4
Switches off the "telescope out" movement as the RK4 operates. Delay about 1,2s.
Control circuit fuse F2 10A
K21: AUXILIARY RELAY FOR SWITCHING OFF THE "BOOM DOWN" MOVEMENT.
Safety limit switch RK4 controls the relay which switches off the spool control circuit of the
relay K5.
Control circuit fuse F2 10A
K22: AUXILIARY RELAY FOR SWITCHING OFF THE "TELESCOPE OUT" MOVEMENT
Closing tip of the safety limit switch RK4 controls the relay which switches off the spool
control voltage of the relay K10, delay 2,5 s.
Control circuit fuse F2 10A
K23: SELECTOR RELAY FOR CONTROL FROM CHASSIS
Controls the solenoid valve for selection of chassis.
Fuse F2 10A
K24: CENTRE POSITION ACTIVATION OF THE JOYSTICK
Pressing the dead-man-switch DMK breaks the control voltage from the spool of the relay
K17 which would otherwise disconnect the control voltage from the micro-switches on the
joystick.
K25: CONTROL OF THE CONTROL CARD
Connects the sensing voltage 0-5VDC to the control card.
K26: RPM-RELAY
Controls the speed of the combustion engine. Increases the speed during performance of the
control movement.
Control circuit fuse F9 1,6A (Platform control panel) and F4 10A (Chassis control panel).
K27: AUXILIARY RELAY FOR POWER SUPPLY TO DRIVING DEVICE
The relay is controlled by limit switch RK3.
