P5-01 Selects the function of the programmable input:
• OFF = Input deactivated.
•
ON
= Input activated (for general functions, such as hour counter enable).
• TAR = Selects the energy tariff (T1 / T2).
•
CLr Part
= Clears the partial energy meters
• CLr Hr = Clears all hour counters.
•
CLr dE
= Clears the max. demand values.
P6-01 Defines the operation of hour counter 1:
•
OFF
= Hour counter deactivated. It is not visible on the display.
• ON = The hour counter is incremented for as long as the energy meter measures
energy.
•
THR
= The hour counter is incremented for as long as the threshold value
defined by parameter P2-01, P2-02 and P2-03 is active.
• INP = The hour counter is incremented for as long as the programmable input is
activated. Parameter P5.01 must be set to ON.
P6-02 Defines the operation of hour counter 2:
• OFF = Hour counter deactivated. It is not visible on the display.
•
ON
= The hour counter is incremented for as long as the energy meter measures
energy.
• THR = The hour counter is incremented for as long as the threshold value
defined by parameter P3-01, P3-02 and P3-03 is active.
•
INP
= The hour counter is incremented for as long as the programmable input is
activated. Parameter P5.01 must be set to ON.
P6-03 Defines the operation of hour counter 3:
•
OFF
= Hour counter deactivated. It is not visible on the display.
• ON = The hour counter is incremented for as long as the energy meter measures
energy.
•
THR
= The hour counter is incremented for as long as the threshold value
defined by parameter P4-01, P4-02 and P4-03 is active.
• INP = The hour counter is incremented for as long as the programmable input is
activated. Parameter P5.01 must be set to ON.
If one of the hour counters is running, the corresponding decimal point flashes.
P7-01 Activates the calculation and visualization of power demand values and max. de-
mand values.
P7-02 Selects the calculation method for reactive power.
•
TOT
: The reactive power contains all harmonics. In this case: P
reactive2
= P
apparent2
-
P
active2
and PF is displayed on the PF/cosφ page.
• FUND : The reactive power only contains the fundamental component. In this
case: P
reactive2
≤ P
apparent2
- P
active2
and cosφ is displayed on the PF/cosφ page.
