2. If the column tends to fall, remove a trim weight (22, 23) or increase pressure.
3. If the column tends to rise, reduce the pressure in steps of 0.15-0.20 bar (2-3 psi) using the Schrader
valve cap (5).
Refit the Schrader valve cap (5).
A correctly pressurized pedestal will balance its payload such that it can be moved to any position over
the full on-shot stroke of the moving column, with minimum effort, and it will maintain its position when
the steering ring is released.
Fine balance and temperature correction may be achieved by adding or removing trim weights.
External connections
The Quattro-SE pedestal has a cable management system (18) which feeds the connecting cables from the
three external ports located on the top of the base next to the pressure gauge (6), to the camera, Head Process-
ing Module and pan and tilt head mounted on the weight tray (1). This self-coiling system neatly stows the cable
as the moving column (16) rises and falls.
The cable management system (Fig 4) locates in the pedestal trim weight stowage slots nearest the pressure
gauge (6) and provides substitute trim weight stowage (10.1) in its base.
CAUTION! A pressure retaining valve prevents pedestal pressure being reduced below approxi-
mately 3.5 bar (50 psi), to prevent damage to the pedestal.
CAUTION! The Schrader valve cap (5) forms a primary pressure seal. Always replace the cap and
screw it down finger-tight to prevent pressure loss.
