Liquid_Temp Function Block
Overview
This function block:
• Receives resistance values from a Sauer-Danfoss liquid temperature sensor.
• Converts these resistance inputs into temperature outputs with a range of 50°C
[122°F] to 125°C [257°F].
About the Input and Output Ranges of the Liquid_Temp Function Block
• Low fluid temperatures cause a liquid temperature sensor to output high resistance
values. The Liquid_Temp function block converts these high resistance values into
low temperature outputs.
For example, the function block converts a1000 Ω input into a 50°C [122°F] output.
• High fluid temperatures cause a liquid temperature sensor to output low resistance
values. The Liquid_Temp function block converts these low resistance values into
high temperature outputs.
For example, the function block converts a 65 Ω input into a 125°C [257°F] output.
PLUS+1 controllers cannot accurately convert resistance values above 1000°Ω or below
65 Ω into temperature values.
• When fluid temperatures below 50°C [122°F] cause resistance values to rise above
1200°Ω, the Liquid_Temp function block:
− Holds its temperature outputs at a steady 50°C [122°].
− Declares an input too high fault.
• When fluid temperatures above 50°C [122°F] cause liquid resistance values to fall
below 60°Ω, the Liquid_Temp function block:
− Holds its temperature outputs at a steady 125°C [257°].
− Declares an input too low fault.
Refer to the hardware application interface (API) specification for more about your
hardware’s capabilities.

Liquid_Temp Function Block Inputs
Input Type Range Description
Flt Tm —— 0–65535
The Flt Tm (Fault Time) input sets the delay, in seconds, before the function block reports faults. The delay
time begins when the controller powers on.
The delay time allows for a warm-up period before the function block starts reporting faults.
1 = 1 s
Ohm —— 60–1200 Ω∗ Input for the resistance values output by a Sauer-Danfoss liquid temperature sensor.
The function block declares out-of-range faults when input values drop below 60 Ω or rise above 1200 Ω.
1000 = 1000 Ω.
