Injection molding machine first section temperature display 998 what reason?
If yes, it is a program problemCheck the wrong places, or the small relays or thyristor components on the PLC (or temperature control board)When the power supply system fails, first check whether the AC power supply is connected to the monitor.
Check that the injection molding machine control instrument display (LCD) is damagedCheck the operating status of the contactor. If it has been connected, check whether the voltage is on the control panel.
Injection molding machine the first section of the temperature display 998, what is the cause of the display problem, digital tube is unusual, need to changeLike Europe mechanical mold temperature machine for this reason may be:1, when the power supply system fails, first check whether the AC power supply is connected to the monitor.2, confirm the AC power supply connected to the console, the ear close to the switching power supply, a short time switch on electricity and listen, if you hear the power of internal issue "Zizi zi..." The noise indicates that the power supply is in the state of self-protection. The reason is that the AC power supply is not normal or there is a short circuit in the machine, which leads to the start of the protective circuit inside the power supply. Please check the procedure as follows:First, with the AC supply voltage multimeter AC voltage 250V file check host power plug, if the AC voltage is more than 240V or less than 150V, overpressure and undervoltage protection circuit will start the host power supply, power supply equipment to stop the machine, please switch manostat or UPS power supply for the host power supply.
