Remote diagnostic system

A remote diagnostic system of a mold handling device loaded with a magnet platen mounting including a magnet clamp mounted on a platen, said magnet platen mounting including a proximity sensor for detecting a proximity/separation state with a mold provided on a surface of the magnet clamp;

• a current sensor for detecting current of each magnetizing coil operably connected to each of a plurality of magnet blocks of the magnet clamp;
• a sensor coil for detecting an attractive force;
• and a current detector for measuring current for driving the plurality of magnet blocks, wherein said remote diagnostic system, comprising:
• a control unit having a main body side memory for determining normal/abnormal state at a time with respect to each of locking instruction and releasing instruction whether release completion and lock completion are normal or abnormal based on detection values detected by the sensor coil and the current detector, and storing together with information as to a status of a main body of the mold handling device of whether or not the main body of the mold handling device is in a mold replacement mode, information as to whether the magnet clamp is in a clamped state or an unclamped state or other state, and time information;
• and
• a terminal device comprising:
• a terminal side memory, said terminal side memory being configured, as to each case of the status of the main body of the mold handling device and the information as to whether the magnet clamp is in the clamped state or the unclamped state or other state, to store messages for diagnosing failures for all combinations of the normal/abnormal state and the proximity/separation state of the proximity sensor, anticipated in advance by a recursive method without omission;
• a terminal side communication unit for reading the status of the main body of the mold handling device and the normal/abnormal state and histories of the proximity/separation state by a wireless communication or a wired communication;
• and
• a display unit for obtaining and displaying messages corresponding to the read histories from the terminal side memory.
