Configuration Parameters
Parameter Description
Output
1. Function Selects the output function. Off (disabled), Control, Event or
Retransmit
Control Output Parameters
2. Output Direction Selects the output direction. Off (disabled), Heat or Cool
3. Loop Selects the control loop assigned to that output. Loop 1 or Loop 2.
Loop 2 available on dual channel model only.
4. Low Power Scale Sets the minimum output power level available for the output. 0 to
100%.
5. High Power Scale Sets the maximum output power level available for the output. 0 to
100%.
Process Parameters
6. Analog Signal Selects the type of analog signal for the output. Voltage or Current.
7. Low Voltage Scale Sets the minimum value for the voltage signal scaling. For exam-
ple, if you want a 1-5 Vdc signal, set Low Voltage Scale to 1.
8. High Voltage Scale Sets the maximum value for the voltage signal scaling. For exam-
ple, if you want a 1-5 Vdc signal, set Low Voltage Scale to 5.
9. Low Current Scale Sets the minimum value for the current signal scaling. For exam-
ple, if you want a 4-20 mA signal, set Low Current Scale to 4.
10. High Current Scale Sets the maximum value for the current signal scaling. For exam-
ple, if you want a 4-20 mA signal, set High Current Scale to 20.
Retransmit Parameters
11. Source Selects what variable is represented by the retransmit signal.
Process 1, Set Point 1, Process 2 or Set Point 2. Loop 2 parameters
available on dual channel model only.
12. Scale Low Sets the value represented by the low voltage or current scale. For
example, if you want a 1-5 Vdc signal to represent 30° to 100°C, set
Scale Low to 30.
13. Scale High Sets the value represented by the high voltage or current scale. For
example, if you want a 1-5 Vdc signal to represent 30° to 100°C, set
Scale High to 100.
14. Offset Shifts the retransmit output signal up or down.
Event Output Parameters
15. Output Source Selects what sources are assigned as inputs to the logic function.
All alarm outputs and any digital inputs are available as input
sources.
16. Output Logic Selects the logic function applied to the alarms and digital inputs
selected. AND or OR logic.
17. Output Active State Selects the output state when the output is active. Energized or
De-engergized.
