savings based on the set value.
Sets the cost per 1 kWh. Multiply the energy payback counter value
with the value set at AP2-89 to calculate the total saved cost. This
value is displayed in AP2-92–93.
AP2-90 Saved kWh
AP2-91 Saved MWh
Displays the saved energy in kWh (AP2-90) and MWh (AP2-91).
When the value reaches 999.9 (kWh) and continues to increase, AP2-
91 becomes 1 (MWH), AP2-90 resets to 0.0, and it continues to
increase.
AP2-92 Saved Cost1
AP2-93 Saved Cost2
Displays the saved cost to the one-tenth place at AP2-92. When the
value reaches 999.9 and continues to increase, AP2-93 becomes 1,
AP2-92 resets to 0.0, and it continues to increase.
Sets the CO2 reduction rate per 1 MW (default value=0.5). The value
is multiplied with AP2-90 and AP2-91, and the resulting values are
displayed at AP2-95 and AP2-96.
AP2-95 Saved CO2-1
AP2-96 Saved CO2-2
Displays the CO2 reduction rate in tons (AP2-95) and kilo-tons (AP2-
96).
Resets all the saved energy parameters.
Note that the actual saved energy may differ from the displayed values, since the resulting
values are affected by user-defined codes sush as AP2-87 and AP2-88.
5.14 Pump Clean Operation
The pump clean operation is used to remove the scales and deposits attached on the
impeller inside a pump. This operation keeps the pump clean by performing a repetitive run-
and-stop operation of a pump. This prevents loss in pump performance and premature
pump failures.
