5. Wire temperature sensors. Temperature sensors are wired as auxiliary inputs.
See Temperature Sensor(s) - page 54.
6. Complete other wiring to congure 5X00 system.
7. Close Front panel -page 40.
8. Calibrate DO sensor - see Calibration “DO” on page 85.
CAUTION: Do not ground the probe body.
Test DO/Temperature Sensors
Apply power to 5X00. See DO Sensor Setup - page 154 to congure DO sensor
inputs. See Temperature Setup - page 150. Calibrate the DO sensor, see DO
calibration - page 82. Verify changes in sensor values occur when the sensor is
placed in environments of dierent 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 sulte
in 0.5 liter of water).
Wire Temperature Sensor(s)
e 5X00 system will support four Temperature/Aux Analog inputs. Temperature
sensors have 2 wires and are terminated at location (5500) L (5400) on I/O
Board - figure 3.20. Temperature sensor(s) must be thermistors with 10K at 25C,
see Appendix 6 Alpha A Curve - page 236.
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ectuer
un câblage quelconque.
1. Mount and install 5X00 and probes - page 27 and page 33.
2. Open front panel - page 42.
3. Feed temperature probe cable through drilled hole in rubber grommet
to location
(5500) L (5400). e terminal strip is removable.
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. ere 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 conguring.

6. Close front panel - page 43
7. Test temperature sensor.
Note:
- Temperature sensors wired to Aux 3, Aux 4, Aux 5, and Aux 6 are displayed
on the 5X00 by default as Temp 1, Temp 2, Temp 3, and Temp 4 respectively.
For instructions on changing the default display settings, see section Name
Devices/Sensors in Chapter 4 Conguring the 5X00.
Test Temperature Sensor
Apply power to 5X00. See Temperature Set up- page 150 to congure temperature
system. Place the temperature sensor in solutions of varying temperature and verify
the sensor readings with another temperature sensor.
