Commissioning
Step 1
Upon power on the controller displays the existing power factor
value “X.XX i” and enters the Automatic Control mode.
The “i” at the end indicates an inductive power factor and would
be appropriate for most installations . A “c” at the end indicates
capacitive power factor and suggests reactive power export and
may not be appropriate . Refer to the troubleshooting section for
resolution steps .
Step 2
Next step is to set up the basic parameters in the controller .
Press the
▼
(down) key to step through the “INFO”, “MANUAL”
and to “SETUP” mode . Press the
▼
( right /Enter) key to enter
the Menu 100 and program and or verify the following values .
Un Nominal voltage (factory programmed, customer may verify)
Ct
CT-ratio (Factory set to 600, Customer to program if
measurement feature is desired. Refer to Step 3). Note
that this ratio is NOT needed for PF correction and is
only required for accurate measurement values. Changing
the CT ratio will change the capacitor step sizes in 402
and those values will have to be re-programmed.
Pt PT-ratio (factory programmed)
Ai Start of automatic initialization (factory programmed)
PFC PF-control ON/OFF/ HOLD (factory programmed)
CP1 Target-PF (customer to program)
St Switching time delay (factory programmed, customer
may verify)
Out Type of each stage (Auto/ Alarm/ Foff/ Fon) (factory
programmed, customer may verify)
Once the Menu 100 is programmed, press the
▼
(left / esc)
key to return to the main screen that displays the existing PF .
