Title (EN) CONTROL VALVE COIL TEMPERATURE CONTROLLER
(FR) DISPOSITIF DE COMMANDE DE TEMPÉRATURE DE BOBINE DE SOUPAPE DE COMMANDE
Abstract:
(EN) A method of actuator coil temperature control for actuators that are not continuously operated, wherein when an actuation current is not being applied to the actuator coil, a) sensing a parameter indicative of the resistance of the actuator coil as an indication of the temperature of the actuator coil, b) if the sensed parameter indicates the temperature of the actuator coil is below a first predetermined limit, then initiating a series of successive actuation current pulses to the actuator coil, each actuation current pulse being terminated before actuation of the actuator occurs, and c) periodically repeating a) and b).
(FR) La présente invention se rapporte à un procédé de commande de température de bobine d'actionneur pour actionneurs qui ne fonctionnent pas en continu. Lorsqu'un courant d'actionnement n'est pas appliqué à la bobine d'actionneur, le procédé a) détecte un paramètre indicatif de la résistance de la bobine d'actionneur en tant qu'indication de la température de la bobine d'actionneur, b) si le paramètre détecté indique que la température de la bobine d'actionneur est inférieure à une première limite prédéfinie, émet une série d'impulsions de courant d'actionnement successives vers la bobine d'actionneur, chaque impulsion de courant d'actionnement se terminant avant que n'ait lieu l'actionnement de l'actionneur, et c) répète périodiquement a) et b).
