Hydraulic UP Pressure Low Switch **
Waiter ’s Gear Controller
X100
Pressure Switch opens when pressure goes above switch set point.
These switches may be purchased from Velocity Aircraft.
Hydraulic DOWN Pressure Low Switch **
X101
** Hydraulic switches normally come as Normally Closed (NC).
This style switch OPENS when the correct pressure is
reached. (Firmware Flag C0 = 1)
If you use Normally Open switches (NO) then Firmware flag
C0 must be set to C0 = 0
HYDRAULIC PRESSURE SWITCHES
10 OCT 2008
Waiter ’s Gear Controller
X107
Must be OPEN
to allow retract
(If not used
must be jumpered to 12vdc )
TILT SWITCH
(Switch closes when airframe
tilted - parked on nose)
(OPTIONAL - Gear safety switch)
NOTE - 1 IMPORTANT - If this is an Infinity installation that
must compress the struts, X106 is used for the strut switches
and is NOT used as a main gear interlock
Must be GROUNDED
to allow retract (NOTE 1)
Squat Switch

OPTIONALLY - Use One Normally Open Pressure
sensor. The sensor should be set to 1100 psi, and
SHORT (contacts close) when 1100 psi is reached.
Firmware C73 must be set to allow the controller to control the Infinity Strut Valve.
