Hx-68P3 Series Outside Humidity and Temperature Transmitters Installation Instructions 6
6. Secure the cable to the wall using cable ties.
Incorporate a drip loop below the cable gland to
prevent water from running into the transmitter
along the cable.

Calibration
There are no calibration adjustments to make for this
device.
Troubleshooting
Analog Output Error State
The output channel is in a defined error level instead of
the measured result in two situations.
• The transmitter detects a measurement
malfunction such as a damaged sensor or
unfavorable environmental conditions.
• The measured values are outside of the scaled
output range. See
Analog Output Overrange
Behavior
.
The error level depends on the output type.
• For a 0 to 10 V output, the error level is 11 V.
• For a 4 to 20 mA output, the error level is 3.6 mA.
The transmitter resumes normal operation of the
analog outputs when the cause of the error state is
removed.
Analog Output Overrange Behavior
The Analog outputs have a defined behavior when the
values measure by the transmitter are outside the
scaled analog output range.
• The output is clipped at the end of the range.
• The output is set to the error state when the
measured value is 5% outside of the scaled range.
• The output resumes normal function when the
measured value is back on the scaled range.
Repair Information
If the Hx-68P3 Series Outside Humidity and
Temperature Transmitter fails to operate within its
specifications, replace the unit. For a replacement
transmitter, contact the nearest Johnson Controls®
representative.

CAUTION: Risk of Electric Shock.
Disconnect the power supply before
making electrical connections to avoid
electric shock.

Terminals 2 and 5 are
internally connected on the
transmitter, so you can use
a cable with four wires.
