Fault indicator
The LED is lit: overload limitation
y
The connected lifting magnet is too big for the
i
MAPLA
system.
The built-in system overload / current limiter is active.
The LED continues to light up after being switched back on.
The LED will not go out until an overload state is no longer
detected after the next time the lifting magnet is switched off.
Note:
Overload limiter active is a warning. On newer
i
MAPLA systems, this
message is not displayed until significant overloads (>110 %) apply.
However, you should check that the lifting magnet is suitable for
the system.
The LED is flashing: system fault
y
A critical safety fault occurred.
The output to the lifting magnet is switched off immediately.
The LED goes out after a system restart.
Ö
The plate cannot be switched on before this.
Note:
On
i
MAPLA systems, a fault blink code is displayed on the MMI
control unit for troubleshooting.
