Abstract

PURPOSE:To improve the operability of a controller and enhance its reliability by a method wherein a controller main body selects from between controlling procedures corresponding to identifying resistance system and to self regulation system in response to the measured value of resistance between the connecting terminals of an input-output connecting terminal group corresponding to the identifying resistance of an identifying resistance system joint. CONSTITUTION:The controller concerned consists of a controller main body, which selects either one of controlling procedures corresponding to identifying resistance system and self regulation system and in which a practicable energizing controlling means 2 is provided, and input-output connecting terminal group 5 equipped with terminals 4e, 4e', 4f, 4f', 4g and 4g', which are connectable to either an identifying resistance system joint 3a or a self regulation system joint 3b. The controlling procedure is selected in response to the measured value of resistance between the connecting terminals 4f and 4f' of an input-output connecting terminal group 5 corresponding to the identifying resistance 6 of the identifying resistance system joint 3a. Since the controller is applied to both the identifying resistance system joint 5a and the self regulation system joint 3b and energizing controlling can be done by controlling procedure corresponding to the system respectively and, in addition, the selection of the energizing controlling procedure is done automatically by the controller, the operability of the controller is favorable and its reliability is also high.

ある。Such automatic energization control methods include an identification resistance method and a self-regulation method. The former method is shown in Figure 4 (
As shown in a), the resistance value of the identification resistor e embedded in the joint b1 together with the heating wire a1 is measured by the controller d, and the type of the joint such as shape and diameter is identified according to the value. The latter method is a method in which a fusion status sensor f such as a pressure sensor or a temperature sensor is installed in advance near the fusion part of the joint b2, as shown in Fig. 4(b). and the controller d2 controls this sensor f.
This method detects a predetermined fusion state and controls energization.
