Chapter 3: Controller Parameter Descriptions
Ambient Sensor Readings (15)
This parameter returns the value of the system ambient sensor in
degrees Fahrenheit to a tenth of a degree. (The ambient sensor is used
for ambient temperature compensation for thermocouples.) Most
Watlow Anafaze controllers have only one ambient sensor; only the
MLS-32 has two. However, the block size has been allocated to allow a
maximum of six ambient sensors per system.
Pulse Sample Time (16)
This parameter is the sample period in seconds for the pulse counter
input. (The pulse input is available for the CLS, MLS, and CAS only.)
• Range: 1 to 20 seconds.
• Default: 1 second.
High Process Variable (17)
This parameter is one of four points used to scale inputs, expressed in
engineering units. (This parameter is affected by the Precision
parameter.)
• Range: –9999 to 30000.
• Default: 14000 (1400F) for J-type thermocouple.
Low Process Variable (18)
This parameter is one of four points used to scale inputs, expressed in
engineering units. (This parameter is affected by the Precision
parameter.)
• Range: –9999 to 30000.
• Default: –3500 (–350°F) for J-type thermocouple.
NOTE
Whenever the Input Type or Units are changed, the High
Process Variable and Low Process Variable parameters are
set to the default values for the Input Type. see Input Type
(3) on page 46 for a list of these values.
