Lenz LS150 stopped receiving commands

[DCCNewb]

I've recently returned to the hobby and have had my points operated via 6 LS150's and 2 DS64's, the controller is a Digitrax Zephyr. Power to the LS150's is via a Gaugemaster transformer.

 

Up until today the decoders have all been working fine but today all of the LS150's have stopped responding to point controls (the DS64's work but they are connected via Loconet). I can still control trains (although I did have trouble with 1 of the loco's responding to the allocated address but that has been sorted).

 

I've checked that there is power on both the track feed and power feed on the LS150's. I'm stuck as to what to try next to find the fault. Is it possible they have all failed at the same time? They were only purchased in the last month or 2.

 

Thanks in advance for any pointers.

If all the power/dcc signal is present, might they somehow have lose or reset their addresses.  Might be worth resetting and reprogramming one of the to see if this is the case.

Thanks for the reply. I've tried to do a factory reset on one of the decoders but it doesn't appear to work. I've also tried reprogramming the addresses and it doesn't move off the solid LED on the decoder.

 

Is it possible it's the Zephyr that's causing the problem? I bought it about 10 years ago but it has been in the box for the bulk of that time unused.

I know you said you checked there was power going to the LS150's but have you checked the voltage? Wonder if the power supply is playing up / bad connection that is not giving enough output for them to work. All failing at the same time is unlikely and the zephyr is likely to either work or not work which is why I wonder about the power supply to them. Are they the only devices being powered from that unit?

[DCCNewb]

Power supply is showing the correct voltage (it's brand new, bought to power the Lenz's specifically). The only things being powered by it are the Lenz decoders.

 

I'd take the items to a local shop, but obviously they are all shut due to the current lockdown.

The transformer I'm using the Gaugemaster GMC-T1 (2 X 16V AC 1 amp outputs). The power at the decoders is reading the same as the unused output.

 

Any other suggestions on what could be causing the problem?

Disconnect all bar one of the LS150's, test it and see if the problem persists. If it does, disconnect that and try another. If one works, reattach each in turn and test until it fails. By a process of elimination you might find the problem.

I am not sure if the LS150's operate the same as the ESU SwitchPilot which I am more familiar with but you could try disconnecting the gaugemaster power supply completely and looping the track power to bot h inputs of the LS150 so it was drawing from the Zephyr as a test to prove if the LS150 was working. Diagram below for clarity -

Thanks for the replies. I did a reset on the zephyr and everything is working again. Not sure how it happened,  but the reset has solved the problem.
