Directions to Configure 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-
figure Aux →Input Type - page 104 .
3. Enter Aux 1-6 in Sensor Setup menu
Menus → System → Sensor Setup→Aux 1-6
4. Configure Control Mode see page 138.
Menus → System → Sensor Setup → Aux 1-6→Set Point Control
→PID/PWM Control
5. Use

7. Configure submenus.
8. Press
to save settings and return to Run Screen.
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 configured for a temperature sensor. Temperature
systems are configured differently for 5400 and 5500D instruments. The differences
are explained below. See Control Mode and Alarms - page 138 before configuring
temperature system.
5400 only - Aux configured temperature systems can be configured as the tem-
perature compensation source for any of the four DO channels. Aux configured
temperature systems can also be configured as independent temperature systems
at any location in the system stream.
The configuration of the DO temperature source is done in the DO Sensor Setup
menu. Sensor Setup menu - page 154.
The 5500D-01, 5500D-02 and 5500D-04 temperature systems can be configured
based on either the aux temperature sensor or the ODO temperature sensor. Aux
configured temperature systems can only be configured as independent temperature
systems. The 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 different 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,
configure chiller on time to 0. The chiller off 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 off time is user selectable. To avoid chiller compressor damage, configure
the chiller hold off time to a value of eight (8) minutes or more. After the chiller
on time expires, the control relay de-energizes for the configured chiller off time.
After the chiller off time expires, the control relay will reenergize if the value is still
in control range. A chiller off time must be configured 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 after systemwide events. Systemwide
events de-energize relays. Example - chiller on time is configured for an eight
(8) minute on time. Energized chiller (control down) relay de-energizes when
5X00 goes into Svr Hold. The chiller on relay had been energized for three (3)
minutes before the Svr Hold occurred. The Svr Hold time is one (1) minute. If
the sensor is reporting control low condition after the service hold time period,
the chiller on time will be for eight (8) minutes and not the remaining five (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 reconfigured when relay is energized.
