CONTROLS AND FUNCTIONS
All controls of XS 190 are hydraulic; only outriggers are electrical. Also the safety limits of
both the lowering of the telescope and the boom and the lifting of the jib operate electro-
hydraulically. The various hydraulic movements have continuously variable speed
adjustment.
THE CONTROL EQUIPMENT IN THE TURNTABLE
1.
The lower control valve is located in the front part of the turntable engine hood, on
the right side, seen from the platform. With the outriggers extended, with the power
switched on from below, with the engine running, the boom may be rotated, lifted,
extended and retracted according the illustrated symbol chart. The emergency lowering
system works using this same lower control valve.
2.
The lower electric control equipment consists of an emergency stop button, an hour
meter, the power switch, an operating button for the emergency lowering pump, an engine
pre-heating signal lamp, a charge warning lamp, an oil pressure warning lamp and an
overheating warning lamp, as well as warning lamps for clogged hydraulic filters. When
extending or retracting the boom from below (at the ground control station), the engine
must be started from the ground control station.
