Error acknowledgment
Three different options are available for error acknowledg-
ment.
Manual (reset button)
Press the reset button on the front of the device.
When pressing the reset button for more than 2 s (approxi-
mately), the device returns to the error state.
Pressing the reset button for more than 6s changes the de-
vice to the "Parameterization" mode.
Manual (remote acknowledgment point)
Connect a button (N/O contact) between the MAN and RES
terminals.
An acknowledgement is triggered as soon as a positive
edge is detected at the MAN input. If no negative edge is de-
tected after approx. 2s, the device adopts an error state
since manipulation or an error in the acknowledgment circuit
may have occurred.
Automatic
Establish an electrical connection between the RES and
AUT terminals.
Following triggering of motor protection monitoring and sub-
sequent cooling, the device performs an automatic acknowl-
edgment.
Feedback
As soon as the device detects an error or indicates a mes-
sage, the reply relay is switched, i.e. the N/O contact is
closed or the N/C contact is opened. This behavior matches
that of a motor protection switch or motor protection relay.
8.3 Parameterization - Nominal current setting
• Press the reset button for more than 6 s to change to the
"Parameterization" mode. The green PWR flashes
once.
In the Parameterization mode, the LEDs are switched off
every 2s for 0.3s to distinguish this mode from other oper-
ating modes.
• Set the nominal drive current with the 240° potentiome-
ter. The nominal current is specified in 16 stages. The
four LEDs show the set current.
• Store this value by pressing the reset button again (non-
volatile area of the mass storage).
• Press the reset button for more than 2s (and less than
6s) to display the set current for 3s. This function is
only possible if 1) the device is not activated, and 2)
there is no error at the device.
The RES terminal provides the voltage for the
reset.
In variants with a rated control supply voltage
of 24VDC, this is 24VDC.
The feedback is for signaling purposes only
and is not part of the safety chain. It is there-
fore not included in the safety considerations.
