If the Skov Fan motor isn't running, several issues could be the cause. First, the signal from the climate controller (10V = stop terminal 5) might be faulty, so you should check that signal. Also, check the start/stop signal from the winch motor (24 V = stop terminal 8). Verify that the power supply is working. Finally, the LPC motor controller could be defective and needs replacement.
Why is my Skov DA 820 LPC Fan making abnormal noises?
If you notice abnormal noise coming from the Skov Fan, there are a few potential reasons. It could be due to faulty mounting, so check the mounting and retighten if necessary. The noise might also be from the bearing, in which case you should replace the motor. Another possibility is a vibrating fan, so inspect the fan blades for defects, correct assembly, or dirt. Replace or clean the blades as needed.
How to troubleshoot reduced performance in Skov Fan?
Reduced performance in your Skov Fan can stem from several causes. The supply voltage might be too low, so measure it. The internal temperature of the LPC motor controller could be too high (over 95°C); check its assembly. If the motor current has reached its limit, and the negative pressure in the livestock house is too high, check the air inlets. An error in the internal circuit of the LPC could also be the issue, requiring you to replace the LPC motor controller. Finally, high ripple voltage could be the culprit, so measure the supply phases.
What to do if Skov Fan motor keeps running and doesn't turn off?
If the Skov Fan motor is running and does not turn off, it could be due to a lack of 24 V DC supply to the winch motor (Terminal H1). Check the 24 V DC supply voltage to resolve this issue.
What to do if the inlet flap of my Skov DA 820 LPC Fan is not operating?
If the inlet flap of the Skov Fan is not operating, it could be due to a lack of 24 V DC supply voltage. Check the 24 V DC supply voltage and the assembly according to the connection and circuit diagram. Another reason might be that the gear motor is not running. Check if the connector is mounted, and if not, replace the gear motor.
How to fix a Skov DA 820 LPC Fan motor that is not running?
If the Skov fan motor is not running, and it's an AC motor, the motor protection might have switched off. Check the size of the protective motor switch (see the Technical data section) and replace it if necessary, ensuring it's the correct size. Also, check if the fan motor is blocked and remove any blockage. Too high negative pressure in the livestock house could also be the cause, so check the air inlets. Another cause might be the control voltage to the motor contactor, in which case you should check the signal to the contactor.
What causes the inlet flap of a Skov DA 820 LPC to not close or open?
If the inlet flap of your Skov Fan won't close or open, it could be because the flap is obstructed by the ventilation duct. Remedy the damage to remove the obstruction. Alternatively, the linkage between the flap and gear may be faulty, requiring you to replace the defective parts. Also, the ON/OFF signal from the controller or manual operation might be lacking.
What to do if Skov DA 820 LPC Fan stopped after multiple restart attempts?
If your Skov Fan has stopped after 5 restart attempts due to the same error within 60 minutes, there are several potential causes: * The supply voltage may be too high, requiring you to measure it. * The motor's power consumption could be too high, indicating motor errors that need checking. * Phase errors (interrupted phases L1, L2, L3) might exist, necessitating voltage measurement between the phases. * A blocked impeller could be the problem, requiring you to remove the blockage. * An incorrect rotation direction could be the cause, prompting you to invert the rotation direction. * Phase error on the motor supply (U, V, W) could be present, requiring voltage measurement to the motor. * An internal communication error might exist, suggesting a replacement of the LPC motor ...
