When the alarm occurs, corresponding alarm indicator of control panel lights, LED
digital display area shows the fault code.
When the factory, the maximum temperature protection value is set to 230℃, the
value corresponds to the parameter F-18.
When the alarm occurs, you can confirm that the first layer of over-temperature
protection (EGO) disabled, the fault can be resolved in accordance with the E-04
alarm elimination methods.
4.4.6 Actual temperature is higher than the sum of set temperature and alarm
temperature—Over-temperature alarm E-07
When the alarm occurs, corresponding alarm indicator of control panel lights, LED
digital display area shows the fault code.
When the factory, the temperature protection value is set to 15℃, the value
corresponds to the parameter F-05.
The significance of the protection is real-time temperature protection, the
protection temperature is a relative value (relative to set temperature), for
example, the current set temperature is 100℃, protection temperature is 15℃, the
alarm occurs when the actual temperature is higher than 135℃.
According to the following steps to eliminate fault:
Check whether the contactor is working properly. In non-energized case, check
the electromagnetic contactor moving contact parts are normal action, if action is
not available, it is recognized contactor damage, if you can operate normally, you
need to energize the machine, when the actual temperature reaches the setpoint,
observe whether contactor movable contact is separate from stationary contact, if
separated the contactor is working properly, if there is no separation, can be
confirmed contactor is working properly by measuring contactor contact voltage, if
electromagnetic contactor contact is still measured the same voltage and control
voltage when actual temperature reaches the setpoint, you can confirm the
microcomputer fault, if not, you can confirm the mechanical part of contactor fault.
Check whether blower is working properly. As actual temperature is measured by
measuring air temperature, thermocouple will measure a stable low temperature
value if the blower is not running, lead to temperature controller has an output
signal to heating pipe to heat all the time, resulting in over-temperature alarm.
Confirm microcomputer panel internal parameters are correct. Microcomputer
panel internal save the PID parameters for controlling temperature heat method, if
the parameters are not correct, will cause heating system heat abnormally. To
