Resetting Metering Parameters
Meter Reset, Parameter 16, is used to clear (reset to 0) the contents of metering
parameters Elapsed Time, Energy, Time to PM (Preventive Maintenance), and
Starts to PM. To clear the contents of any one of these parameters, configure
Meter Reset to the specific parameter you wish to clear.
To access Meter Reset using the 20-HIM-A6, perform steps 1…4,
.
1.
From Step 4, select the
Metering Basic Group
, then press ENTER
(number 5 on the keypad).
2.
Use the down arrow on the keypad to select/highlight
Meter Reset
.
3.
With Meter Reset highlighted, press the ENTER key (number 5 on the
keypad) or the ENTER soft key.
4.
Press the EDIT soft key.
5.
Use the up or down arrow to select the desired parameter (Elapsed Time,
Energy, Time to PM, or Starts to PM) to be reset, then press the soft
ENTER soft key. The selected parameter is reset to zero with the
exception of the Starts to PM.
Metering Parameters
Current
The SMC-50 control module calculates true RMS current based on Current
Transformer (CT) feedback for all three phases. It also calculates an average value
of the three phase currents. During Braking operation, the calculated current is
estimated based on time and current settings. This parameter reports the three-
phase motor current measurements. These measurements are always line current,
regardless of the type of connection. The accuracy of the current calculation is
±5% of the true RMS current.
TIP
With the exception of the Meter Reset, Parameter 16, the metering
parameters contained in the Monitoring File-Group are Read (R) only. See
Metering Parameters on page 122
for a
detailed list of metering parameters.
EXAMPLE
To clear (reset to 0) the Elapsed Time, configure Meter Reset to Elapsed Time.
The controller will then clear the Elapsed Time and the value of Meter Reset
will return to Ready 0.
TIP
When the ENTER key is pressed and Starts to PM is selected, its contents is
set to the value contained in PM Starts, Parameter 127.
