leads should not be moved or extended because
of the possibility of inducing electronic noise into
the INT69SCY, which could cause false trips of the
module.
Module and Sensor Functional Check
The following fi eld troubleshooting procedure can be
used to evaluate the solid state control circuit: Refer to
Table 6
for a technical data summary.
Module Voltage Supply Troubleshooting
Verify that all wire connectors are maintaining
•
a good mechanical connection. Replace any
connectors that are loose.
Measure the voltage across T1-T2 to ensure
•
proper supply voltage.
Determine the control voltage by using a voltmeter
•
and then measure the voltage across the M1-M2
contacts:
If the measured voltage is equal to the control
a.
volts then the M1-M2 contacts are open.
If the measurement is less than 1 volt and the
b.
compressor is not running, then the problem
is external to the INT69SCY or INT69SU
module.
If the voltage is greater than 1 volt but less than
c.
the control voltage, the module is faulty and
should be replaced.
Sensor Troubleshooting
Remove the leads from S1-S2, and then by using
•
an ohmmeter measure the resistance of the
incoming leads.
CAUTION: Use an Ohmmeter with a maximum
