4. Function

4.1. Operation and operating modes

4.1.1. Status LEDs
The solid-state reversing contactor displays
the operating conditions with a total of four
LEDs. The functions of the LEDs are based
on the NAMUR recommendation NE 44.
After the rated control supply voltage is
applied, all LEDs light up once as LED test.
The operating status of the relay is display-
ed via a green LED.
An external error (process error: overcur-
rent, asymmetry, phase failure) is signaled
by a red LED. The device is currently in a
secure deactivated state. An error acknow-
ledgment is required to exit this state.
The reverse or forward running of the drive
is always displayed by a yellow LED.
4.2. Parameterization /
Nominal current setting
• Activate the reset button for more than 6 s to
reach the operating mode "Parameterization" -
the green LED PWR flashes once.
The LEDs are switched off at intervals of 2 s for 0.3 s
in the operating mode "Parameterization" to diffe-
rentiate from other operating conditions.
• Set the rated current of the drive with the 240°
potentiometer. The four LEDs display the set
current. The rated current is displayed in 16
stages.
• Store the value by pressing the reset button again
(retentive area of the memory).
• Actuate the Reset key for more than 2 s (and less
than 6 s) to display the set current for 3 s.
This function is possible only if
1) the device is not activated, and
2) there is no defect in the device.
Overload current factor:
The ratio between the actual current and the
parameterized rated current.
From a motor current of 12 A or 45 A, the
blocking monitor is activated
(refer to 6.1. Tripping characteristics).
