Calibrate DO sensor - see Calibration "DO" on page 83.
: Do not ground the probe body.
CAUTION
Test DO/Temperature Sensors
Apply power to 5X00. See DO Sensor Setup - page 173 to configure DO sensor
inputs. See Temperature Setup - page 168. Calibrate the DO sensor, see DO
calibration - page 81. Verify changes in sensor values occur when the sensor is
placed in environments of different oxygen concentration and temperature. For
example, the DO reading in saturated air for calibration versus the DO reading
when the sensor is placed in a zero oxygen environment (mix 1 gram sodium sulfite
in 0.5 liter of water).
Wire Temperature Sensor(s)
The 5X00 system will support four Temperature/Aux Analog inputs. Temperature
sensors have 2 wires and are terminated at location
Board - figure 3.20. Temperature sensor(s) must be thermistors with 10K at 25˚C,
see Appendix 6 Alpha A Curve - page 256.

Directions to Wire Temperature Sensor(s)
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l'alimentation externe de l'unité avant d' e ffectuer
un câblage quelconque.
1.
Mount and install 5X00 and probes - pages 27 and 34.
2.

Feed temperature probe cable through drilled hole in rubber grommet
(5500) L (5400). The terminal strip is removable.
to location
CAUTION
: Run high and low voltage cables through separate bulkhead and
conduit.
4.
Terminate temperature sensor wires to Aux 3, Aux 4, Aux 5, and/or Aux
6 system. There is no polarity for temperature sensor wires; therefore,
(+) and (-) terminals are interchangeable. Make sure the temperature
sensor wires are terminated to the (+) and (-) terminals for the Aux
system (3, 4, 5, 6) you are configuring.
