Technical knowledge | Regarding the handling method of high-frequency wall saw control power failure alarm
Nov 14,2026
During the use of high-frequency wall saws, there may be control power failure alarms, and the equipment may not start normally or stop halfway. This is one of the most common alarms for high-frequency wall saws, and in most cases it is not a malfunction of the equipment itself. Users can troubleshoot and handle it themselves.
Fault phenomenon:
During the startup or cutting process, the control system prompts a power failure alarm, and the equipment cannot start or automatically stops.
Cause of occurrence:
The fundamental reason for the control power failure alarm is that the input voltage is not within the specified range, that is, the voltage is too high or too low. Common situations include: unstable voltage in the construction site power grid, multiple high-power devices using electricity at the same time causing voltage to be pulled low, thin cable diameters or loose wiring causing excessive voltage drop, and long temporary power distances.
resolvent:
The first step is to check the grid voltage and use a multimeter to measure the actual voltage at the device access point to confirm if it exceeds the voltage range specified by the device.
Step 2：adjust the voltage to the normal range: if the voltage is too low, check the power supply capacity of the construction site, avoid peak electricity consumption, replace the cable with a thicker diameter, and tighten the wiring terminals; If the voltage is too high, check if the power supply terminal is abnormal and install voltage stabilizing equipment if necessary.
Step 3: After confirming that the voltage has returned to normal, power on the device again and the alarm will be cleared, and the equipment will resume normal operation.
Notes:
High frequency wall saws require high voltage stability, and long-term use in environments with substandard voltage can shorten the lifespan of motors and control systems. It is recommended to equip the construction site with dedicated power supply lines and regularly check the wiring situation to reduce the occurrence of control power failure alarms from the source.
If the alarm still exists after the voltage has been adjusted to the normal range, please contact the manufacturer's after-sales service for further maintenance.
