Directions to Congure Aux (non temperature analog)
1. Wire Aux analog devices - page 59.
2. Select “0-1v”, “0-5v”, or “4/20ma” input type at Menus → System → Con-
gure Aux →Input Type - page 104 .
3. Enter Aux 1-6 in Sensor Setup menu
Menus → System → Sensor Setup→Aux 1-6
4. Congure Control Mode see page 138.

Note:
- It is important to keep the 5X00 at the Run Screen during normal opera-
tion. Alarm functionality (email alarms, activation of enabled alarm relays,
alarm icons, and buzzer) is suspended when 5X00 is not at Run Screen.
Temperature
Menus → Sensor Setup→Aux 3-6
Aux 3, 4, 5 and 6 can be wired and congured for a temperature sensor. Temperature
systems are congured dierently for 5400 and 5500D instruments. e dierences
are explained below. See Control Mode and Alarms - page 138 before conguring
temperature system.
5400 only - Aux congured temperature systems can be congured as the tem-
perature compensation source for any of the four DO channels. Aux congured
temperature systems can also be congured as independent temperature systems
at any location in the system stream.
e conguration of the DO temperature source is done in the DO Sensor Setup
menu. Sensor Setup menu - page 154.
e 5500D-01, 5500D-02 and 5500D-04 temperature systems can be congured
based on either the aux temperature sensor or the ODO temperature sensor. Aux
congured temperature systems can only be congured as independent temperature
systems. e DO system temperature compensation value is always taken from the
temperature sensor in the ODO probe.

Range High Timed and Normal Control
Temperature high control can operate in two dierent modes: normal or timed.
Temperature low control operates in normal mode only. In the normal mode, the
control relay is energized until the set point value is reached. For normal control,
congure chiller on time to 0. e chiller o time will be ignored.
In temperature high control timed mode, the control relay is energized for the
chiller on time, regardless if the sensor value has returned to the set point value.
Chiller o time is user selectable. To avoid chiller compressor damage, congure
the chiller hold o time to a value of eight (8) minutes or more. Aer the chiller
on time expires, the control relay de-energizes for the congured chiller o time.
Aer the chiller o time expires, the control relay will reenergize if the value is still
in control range. A chiller o time must be congured in the timed mode or the
control relay will never de-energize.
Notes:
- Since most heaters and chillers have their own thermostats, their thermostats
can be used as a backup temperature control system. Set the heater thermostat
control several degrees above the desired temperature and the chiller thermo-
stat control several degrees below the desired temperature.
- Active sensor control timers are reset aer systemwide events. Systemwide
events de-energize relays. Example - chiller on time is congured for an eight
(8) minute on time. Energized chiller (control down) relay de-energizes when
5X00 goes into Svr Hold. e chiller on relay had been energized for three (3)
minutes before the Svr Hold occurred. e Svr Hold time is one (1) minute. If
the sensor is reporting control low condition aer the service hold time period,
the chiller on time will be for eight (8) minutes and not the remaining ve (5)
minutes of the chiller on time prior to entering Svr Hold.
- Control down relay (chiller) energizes for original “on time” if chiller “on
time” is recongured when relay is energized.
