Applications
Important: Use this A19QSC Series Temperature
Control only as an operating control. Where failure
or malfunction of the temperature control could
lead to personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintain other devices,
such as supervisory or alarm systems or safety or
limit controls, intended to warn of or protect against
failure or malfunction of the temperature control.
Important: Utiliser ce A19QSC Series Temperature
Control uniquement en tant que dispositif de
contrôle de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du temperature
control risque de provoquer des blessures ou
d'endommager l'équipement contrôlé ou un
autre équipement, la conception du système de
contrôle doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer
de façon permanente d'autres dispositifs, tels
que des systèmes de supervision ou d'alarme, ou
des dispositifs de sécurité ou de limitation, ayant
une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du
temperature control.
