Homing the Quattro SE system
When the Quattro SE system is initially powered up it will set X, Y (floor) travel and pedestal
orientation to zero, therefore the pedestal must be ‘homed’ relative to a floor target. Periodically the
error in X, Y (floor) travel and pedestal orientation will increase to a level where it is necessary to
‘rehome’ the pedestal relative to a floor target.
There are currently two versions of the Quattro-SE pedestal, each using a different optical sensor
arrangement and floor target. The MK I pedestal uses a three-line floor target (Figure 6) and the MK
II pedestal uses a two-line reflective tape target (Figure 7).
• From the Quattro PDA main window, select HOMING (10). The Homing window appears
(Figure 5).
Homing a MK I pedestal
To home a MK I pedestal to the studio target datum (X and Y axis):
1. Select 3 LINE TARGET (18) from the homing window (Figure 5). You can return to the main
window without affecting homing settings by selecting cancel (21).
2. Position the pedestal over the floor target as shown in (Figure 6), ensuring that the pedestal
orientation is also approximately correct.
NOTE: Before you start the homing process, check which version of pedestal
you are using by looking at the floor target installed.
