a. Function Not "Enabled": no
diagnostics.
b. "Enabled": Out-Of-Range
Low or Hi or bad LLID, set
diagnostic, default CWS to next
level of priority (e.g. Front
Panel SetPoint). This Info
diagnostic will automatically
reset if the input returns to the
normal range.
Same as External Chilled Water
Setpoint
The system differential
pressure for the respective
circuit was above 19.2 bar for 2
consecutive samples or more
than 10 seconds.
Same as High Differential
Refrigerant Pressure - Circuit 1
The liquid level sensor is seen
to be at or near its high end of
range for 80 contiguous
minutes while the compressor
is running. (The diagnostic
timer will hold, but not clear
when the circuit is off). Design:
80% or more of bit count
corresponding to +21.2 mm or
more liquid level for 80
minutes)
