The regulator will not accept new values beyond the
limitations. See section 18. It is possible to check the
limitations by selecting <<Lim>> (limits).
5. The arrow on the screen (Fig. 12.13) indicates to use the

can be activated by Atlas Copco. The power recovery time (the
period within which the voltage must be restored to have an
automatic restart) can be set between 1 and 254 seconds or to
symbol 00!. If the power recovery time is set to 00!, the
compressor will always restart after a voltage failure, no
matter how long it takes to restore the voltage. Provide a label
near to the control panel warning the operator that the compressor
automatically restarts if the voltage is restored.
