TranslationHelper::setMaxTranslations() 

\nn\t3::TranslationHelper()->setMaxTranslations($maxTranslations); 

Sets the maximum number of translations to be made per instance. Helps with debugging (so that the Deep-L quota is not exhausted by testing) and with TimeOuts if many texts need to be translated.

$translationHelper->setMaxTranslations( 5 ); // Abort after 5 translations

public function setMaxTranslations($maxTranslations) {
	$this->maxTranslations = $maxTranslations;
	return $this;
}
