lamp is out (flashing is hardly recognizable)
: during the closing movement the protective field is at least par-
tially activated
lamp is constantly on
: The protective field of the AKAS® ist not activated. AKAS® only permits closing strokes
in slow speed.
The lamp is flashing slowly :
about once per second: EDM is not in Stop condition, or the rear reset button
must be released, or the press brake must be opened completely in order to quit the slow speed range to enba-
ble the triggering of SP = 0.
The lamp is flashing rapidly:
about five times per second: AKAS® is in interlock state. Carry out a voltage reset.
LEDs are flashing slowly
about once per second: Press has successfully stopped at the cam during the over-
run traverse test, only when the cam is free again, the OSSDs can be enabled again. The ajustment controll-
LEDs are flashing slowly until the press brake is not opened completely.

equivalent protective door contacts:
LEDs are lit if all
protective door circuits/Emergency OFF circuits are
closed.
antivalent protective door contacs:
NA1 and
NA3 are lit, NA2 is dark if all protective door circuits/
Emergency OFF circuits are closed

SGA is lit if fast speed is permitted
antivalent inputs: FUS is lit, FUO is dark if foot pedal is activated. equiva-

If the lateral protective doors are open:
all other protective doors / protective circuits must be closed. NA1
must be lit. NA2, NA3 must be dark if the protective door contacts are equivalent.
If the protective door contacts are antivalent, NA2 must be lit, and NA3 must be dark. If necessary check the con-
tacts). IF the RXOK-LEDs are not lit, activate the RESET-Button(s). If the LEDs still remain dark, open and close
all other protective doors / protective circuits , then activate the RESET-Button(s).
If the lateral protective doors are closed:
all other protective doors / protective circuits must be equally closed.
NA1 , NA2, NA3 must be lit if the protective door contacts are equivalent.
If the protective door contacts are antivalent, NA1 and NA 3 must be lit, and NA2 must be dark . (If necessary
check the contacts). IF the RXOK-LEDs are not lit, activate the RESET-Button(s). If the LEDs still remain dark,
open and close all protective doors / protective circuits , then activate the RESET-Button(s).
