LEDs:
If certain threshold values are exceeded, the alarm and/or warning LED lights up. A status and alarm text appear on the control panel.
The On LED is activated when the adjustable frequency drive receives power from AC line voltage, a DC bus terminal, or an external 24 V supply. At the
same time, the back light is on.
•
Green LED/On: Control section is working.
•
Yellow LED/Warn.: Indicates a warning.
•
Flashing Red LED/Alarm: Indicates an alarm.

Menu keys
The menu keys are divided into functions. The keys below the display and
LEDs are used for parameter set-up, including choice of display indication
during normal operation.
[Status]
Indicates the status of the adjustable frequency drive (and/or the motor) or the filter respectively. On the drive LCP, 3 different readouts can be chosen
by pressing the [Status] key:
5 line readouts, 4 line readouts or Smart Logic Control.
Smart Logic Control is not available for the filter.
Use
[Status]
for selecting the mode of display or for changing back to display mode from either the quick menu mode, main menu mode or alarm mode.
Also use the [Status] key to toggle single or double readout mode.
[Quick Menu]
Allows quick set-up of the adjustable frequency drive or the filter.
The most common functions can be programmed here.
The [Quick Menu] consists of:
-
Q1: My Personal Menu
-
Q2: Quick Set-up
-
Q3: Function Set-ups (drive LCP only)
-
Q5: Changes Made
-
Q6: Loggings
The Function set-up provides quick and easy access to all parameters required for the majority of water and wastewater applications including variable
torque, constant torque, pumps, dosing pumps, well pumps, booster pumps, mixer pumps, aeration blowers and other pump and fan applications. Among
other features, it also includes parameters for selecting which variables to display on the LCP, digital preset speeds, scaling of analog references, closed-
loop single zone and multi-zone applications and specific functions related to water and wastewater applications.
Since the active filter is an integrated part of the low harmonic drive, only a minimum of programming is necessary. The filter LCP is mainly used to
display information about filter operation such as THD of voltage or current, corrected current, injected current or Cos
ϕ
and True Power Factor.
The Quick Menu parameters can be accessed immediately unless a password has been created via par. 0-60, 0-61, 0-65 or 0-66.
It is possible to switch directly between Quick Menu mode and Main Menu mode.
[Main Menu]
is used for programming all parameters.
The Main Menu parameters can be accessed immediately unless a password has been created via par. 0-60, 0-61, 0-65 or 0-66. For the majority of water
and wastewater applications it is not necessary to access the main menu parameters, but instead the quick menu, quick set-up and function set-ups
provide the simplest and quickest access to the typical required parameters.
It is possible to switch directly between Main Menu mode and Quick Menu mode.
Parameter shortcut can be carried out by pressing down the
[Main Menu]
key for 3 seconds. The parameter shortcut allows direct access to any
parameter.
