Note: If you selected the Sn-d sensor in Step 2, the Select Relay Differential OFF Value (dOFF
x
) screen is
displayed. Press or to select the temperature, pressure, or humidity differential value at which the
relay turns OFF. Press to save the dOFF value and go to the next screen. (See Differential Control
on
page 24 for more information.)
5. In the Select ON Time Delay (ONd
x
) screen, press or to select the number of seconds that the relay
output delays going to the On state after the Relay ON (or dON) value is reached. Press to save the ONd
value and go to the next screen. (See Relay On and Off Duration Control
on page 15 for more information.)
6. In the Select OFF Time Delay (OFFd
x
) screen, press or to select the number of seconds that the relay
output delays going to the OFF state after the Relay OFF (or dOFF) value is reached. Press to save the
OFFd value and go to the next screen. (See Relay On and Off Duration Control
on page 15 for more
information.)
7. In the Select Minimum Relay ON Time (ONT
x
) screen, press or to select the minimum number of
seconds that the relay remains On after the Relay goes ON. Press to save the ONT value and go to the next
screen. (See Relay On and Off Duration Control
on page 15 for more information.)
8. In the Select Minimum Relay OFF Time (OFFT
x
) screen, press or to select the minimum number of
seconds that the relay remains Off after the Relay goes OFF. Press to save the OFFT value and go to the
next screen. (See Relay On and Off Duration Control
on page 15 for more information.)
9. In the Select Sensor Failure Mode (SNF
x
) screen, press or to select whether the output relay stays on
or off when a sensor failure is detected. Press to save the Sensor Failure Mode value and go to the next
screen.
10. In the Edit Sensor (SENS
x
) screen:
• If the displayed sensor (Sn-1, Sn-2, Sn-3, Sn-d, HI-2, or HI-3) is the correct sensor for the output relay, the
output setup is complete. Press to return to the Relay Output Setup Start screen.
• If the displayed sensor (Sn-1, Sn-2, Sn-3, Sn-d, HI-2, or HI-3) is not the correct sensor for the output relay,
press or to select the correct sensor. Press to save the new sensor selection and go to the Relay
Output Setup Start screen. Press again to go to the Relay ON Value screen and repeat Step 3 through
Step 10 for the new sensor.
The relay output is set up and saved in the control module. If you need to set up the next output, press to
navigate to the next Output Setup Start screen. If you have completed your control system setup, press and
simultaneously or wait two minutes to return to the Main screens.
Setting up an Analog Output
Analog Outputs provide proportional analog control signals to controlled equipment based on the sensed
conditions. See Analog Outputs
on page 18 for more information.
When you supply power to a module assembly, the control module polls all of the connected modules, detects all of
the outputs in the module assembly, then assigns an output number to each output, and enables an Analog
Output Setup Start (OUTA
x
) screen for each analog output detected (Figure 29 on page 49). See Analog Outputs
on page 18 for more information.
Note: The condition (temperature, pressure, or humidity), unit of measurement, minimum differential value,
default setup values, and condition value ranges available in the output setup screens are determined by
the Sensor Type of the sensor that you select for the output. See Table 5 on page 24 for more information
on sensors that are compatible with System 450 standard control modules, their Sensor Types, and the
values and ranges associated with each Sensor Type.
The Setpoint (SP) and End Point (EP) parameters allow you to set up a proportional band (or throttling range) for
the control loops in your controlled system.
