control centre).
K15:
LEVELLING THE PLATFORM
Levelling the platform backward
Control circuit fuse F9 1,6A (Platform control centre) and F4 10A (Chassis
control centre).
K16:
LEVELLING THE PLATFORM
Levelling the platform forward
Control circuit fuse F9 1,6A (Platform control centre) and F4 10A (Chassis
control centre).
K17:
CENTRE POSITION ACTIVATION OF THE JOYSTICK
Switches off the voltage from micro-switches of the joystick, if the dead-man-
switch DMK has not been pressed while the joystick is in the centre position.
K18:
CONTROL RELAY FOR THE ADDITIONAL RESISTORS CONTROLLING THE
MOVEMENT SPEED
The relay switches over the control voltage from the propo-card to the
adjustable resistor for the boom/levelling of platform.
When the relay is active, the control voltage is routed via the resistor TR10
(movement speed of the boom from the chassis control centre)
As the relay is not active the control voltage is supplied through the TR9
resistor (levelling of platform )
Control circuit fuse F9 1,6A (Platform control centre) and F4 10A (Chassis
control centre).
K19:
CHANGE-OVER RELAY FOR THE 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 centre) and F4 10A (Chassis
control centre).
K20:
FUNCTION RELAY FOR THE OUTREACH LIMIT SWITCH RK4
Switches off the “telescope out” movement as the RK4 operates. Delay about
1,2 sec.
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 sec.
Control circuit fuse F2 10A.
