ECM MOTOR
TECINspect Service Tool
24VAC
Connect the two alligator clips from the
TECINspect
®
Service Tool to a constant 24VAC
(24VAC terminal and Common terminal) source
such as the transformer low-voltage terminals or
terminal strip on the manufacturer’s control board
(see Figure 3 below). These connections are not
polarity sensitive.
Figure 3
NOTE: The high voltage
5-Pin connector must be
connected to the motor
for TECINspect tests.
Place the TECINspect Service Tool switch(es) in
the OFF position.
Reconnect the AC power to the system. The
green LED light on the TECINspect Service Tool
should be on when connected properly to 24VAC.
If the green LED light is not on, there is no power
to the TECINspect Service Tool or the TECINspect
Service Tool has failed. Do not continue until the
green LED is on by correcting low voltage issue/
connections or replacing the TECINspect Service
Tool.
Refer to the table on the back of the
TECINspect Service Tool for operation
guidelines. Observe the motor for a minimum of
15 seconds.
If using a TECMate XL on Models 2.0 / 2.3 /
Eon
®
, make sure to set the switches according to
the instructions on the back for each demand test
to eliminate misdiagnosing the problem.
