Diagnosed running rate
=(-(Set temp.)X0.9)+((ATX0.9-4.5
䉝
))-((Set temp.+85
䉝
) / 10))
You can know running status by the calculation for diagnosed running rate.
Diagnosis is done by comparing running rate for 8 hours operation after 2 hours
elapses since unit started cycle operation, with diagnosed running rate.
(Diagnosed running rate – running rate) < 0 … Normal (DP52 goes off)
(Diagnosed running rate – running rate)
䍻
0 … Overload operation (DP52 illuminates)
222 = Running rate cannot be obtained by calculation. (DP52 goes off)
Diagnosis is done in every 8 hours.
