Nice MC824H gate stuck open

[Markp80]

Hi guys,

We have a Nice MC824H installed and recently it started to play up whereby the gates would stay open.

I ordered a new set of Nice EPMB photocells, fitted them and performed the blue bus learning procedure. This seemed to fix the gates and they started working again. However, I noticed the sensor on one side had no power and they do not stop the gates from closing when you get i  the way. I now tried to see why it waa getting no power to no avail and stopped the gates mid way. The gates are now stuck open again. 

I have tried disconnecting the photocells and performing the rearning procedure without them but the gates remain open. 

I found an old post that mentioned which lights should be on. Bluebus flashes green once per second, L3 and L4 are slowing flashing and Stop is permanently on red which I beleive is correct. However, neither ENC1 or ENC2 is lit. 

Should they be and if not, what could be the problem? I opened up the junction box for the motor power and it is full of cobwebs. Wondering if it could be due to moisture or a fuse perhaps.

Thanks in advance for your help.

Hi Mark,

This sounds like it could possibly be an issue with an encoder, I would advise checking for any loose connections on your encoders. However, if there is water ingress present as you have said it could be caused by this, otherwise this could have just been a malfunction of the encoder. If the encoder is faulty the motor may need replacing however.
