1 Leave the intelligent eye sensor connector S602 connected to the indoor unit
main PCB.
2 Wave your hand in front of the left side (when facing the indoor unit) of the
intelligent eye sensor and measure the voltage between the following pins of
the intelligent eye sensor connector S602.
Result: The measured voltage MUST be:
Connector pins Voltage
2‑3 4.25~4.75VDC
2‑4 0VDC
3 Wave your hand in front of the right side (when facing the indoor unit) of the
intelligent eye sensor and measure the voltage between the following pins of
the intelligent eye sensor connector S602.
Result: The measured voltage MUST be:
Connector pins Voltage
2‑3 0VDC
2‑4 4.25~4.75VDC
Is the measured voltage correct? Action
Yes Intelligent eye sensor is OK. Return to
troubleshooting of the specific error
and continue with the next procedure.
No Continue with the next step.
4 Again, wave your hand in front of the left side (when facing the indoor unit) of
the intelligent eye sensor and measure the voltage between the following pins
of the intelligent eye sensor connector CN.
Result: The measured voltage MUST be:
Connector pins Voltage
2‑3 0VDC
2‑4 4.25~4.75VDC
5 Again, wave your hand in front of the right side (when facing the indoor unit)
of the intelligent eye sensor and measure the voltage between the following
pins of the intelligent eye sensor connector CN.
Result: The measured voltage MUST be:
Connector pins Voltage
2‑3 4.25~4.75VDC
2‑4 0VDC
Is the measured voltage on the
intelligent eye sensor correct?
Action
Yes Replace the intelligent eye sensor
wiring harness, see "Repair
procedures"[4122].
No Replace the intelligent eye sensor, see
"Repair procedures"[4122].
