TP1
Cheetah Xi controller ground reference
test point
Use when making DC voltage
measurements on the control board
Normal ground fault limits (TP1 to
Chassis): 2.17 VDC nominal for Level 1
and 5 VDC nominal for Level 2. If a
ground fault is present, voltage will sway
in either direction.
Ground fault detection impedances are 60K
Ω
between power ground and chassis
ground or 1M
Ω
between main power and
chassis ground
TP2
Positive (+) side of the Cheetah Xi
controller 24 VDC power bus
To verify controller voltage, connect
positive lead of voltmeter to TP2 and
ground lead of voltmeter to TP1
