Telemetry Module MT-021 User Manual

Data type
- number
Range - 0...32767
Default value - 100
Comments
- Setting hysteresis relevant for signal fluctuations prevents
excessive activations of alarm flags.
6.2.6.1.3.14. Deadband - engineering units
Function
- This parameter defines a minimal change of registered analog
signal to react on.
Data type
- number
Range - 0....32767
Default value - 100
Comments - When set to value 0, the flag will rise upon every detected
signal change by minimum 1 engineering unit. Deadband flags
are dedicated to continuous monitoring of analog signal
changes.
6.2.6.1.4. Inputs 1-WIRE1, 1-WIRE2
MT-021 module is equipped with two 1-WIRE inputs which allow connection of external
transducers (e.g. temperature sensors).
6.2.6.1.4.1. Name
Function - Defines input's user friendly name
Data type - Text
Range - Letters and numerals, max. 16 characters
Default value - Respectively (1-WIRE1, 1-WIRE2)
Comments - Assigning friendly names facilitates discrimination of
inputs destination and required settings.
6.2.6.1.4.2. Input type
Function
- selection of 1-WIRE input mode
Data type
- selection list
Range
- Temperature measurement
Temperature measurement by DS18B20 sensor
Inactive
Input switched off
Default value - Inactive
Comments - N/A
6.2.6.1.4.2.1. Temperature measurement
In this mode, the input module performs temperature reading from the DS18B20
sensor connected to a 1-Wire bus. Configuration parameters associated with that
operation mode allows to set alarm thresholds, hysteresis and deadband.
