4.9.2.2 ZMR Automatic mode
In "automatic" ZMR operating mode, the contactor is ready to reclose imme-
diately after the thermal image drops below 100-%-mark. The "automatic"
ZMR operating mode is activated by setting the ZMR M/A output bit (output
byte 0, Bit 3).
The following diagram (Fig. 54) illustrates the switching behavior of the con-
tactor after an overload with the "automatic" ZMR operating mode active.

DANGER
If the switch on command for the contactor is sent in "auto-
matic" ZMR operating mode, the motor starts up automatically
after the thermal motor image falls below the 100-%-mark.
