Golden Rail Relays
-
-
I have been asked to ressurect an ancient Stannah Golden Rail for a few weeks.
The pcb is the 4 relay version same as 215 and early 225 and there is some serious arcing going on so I intend to fit a new set of relays as the existing ones are badly pitted and aren’t going to clean up.
I have forgotton to get the ID codes off of the relays, I know there is a single Omron LY2 and 2 Omron LY4 48Volt relays, so wondered if anyone knew the last relay ID? Omron MY4 possibly?
IIRC the earlier lifts didn’t use a motor brake, did they simply rely on the motor gearbox friction for stopping?
This unit seems to be running on a fraction and it’s definitely not a soft stop pcb. Can anyone still remember them? -
If this unit is running on then there is brake slide, if this is more than 20mm then the lift does not comply. The brake is actually housed inside the motor cowl and under the cooling fan and wired as DC through a full wave bridge rectifier. Relay’s were for Power, MC – motor control and the two directional up & downs.

Thanks Robbie I know what the relays are for, just wanted to ensure correct parts were sourced, managed to dig out a very old dusty circuit diagram which confirmed the last relay as an MY4 48v.
Only thing under the cooling fan is the centrifugal switch for disconnecting the start circuit on this one.
As for the motor I never knew they had a rectifier inside, I thought they were AC induction motors. -
Hi Kev, Ahhh, long time since i last seen a 209 or 219 obviosuly a little confused. if there is no soleniod brake it will be inside the motor.like the 215 model. it will be a cone brake with a rubber lining unlike a 225 model. do have drawings and pcb circuit diagrams archived away, again cant remember how may wires this motor has. if just 3 wires, assume it has the ruber brake cone. stripping down cleaning the spline and a bit of emery paper to the motor cone in the cowl will help, just dont lubricate 🙂 i do remember having to remove centrifugakl switches on the 215 to get to the brake which is a 3 wire motor. motors are AC, but solenoid brakes are DC to prevent them being turned into a buzzer. the 230 model had a solenoid brake and the rectifier is on the board as it is on a Bison Classic AC. if you had a Brooks Deluxe, the brake is wired into the motor connection point, this is where you would find the rectifier. good luck, those old GSL’s were great.

you can also still source those relays from RS

When you say gold rail I assume you mean the 205?
-
@Nsl The 205 was a straight stairlift, I think the first was manufactured in 1975.
Curved lifts had painted gold hamerite rails, also known as Golden Rails or GSL IE 209GSL 219GSL 229……250,260….
The straights, known as silver rails, therefore 205SSL, there are also economy models for local authorities eg 225SLE -
I stand corrected. You learn something every day. I’m not familiar with the stannah curves before the 228.

Not being ageist, but it is an age thing!

I have a whole board complete with good relays if you want to pop in and grab it Kev, think i owe you a favour

Thanks mate, I found one in the darkest depths of my store.
This lift is a nightmare though, fitted brand new relays and still had relay contacts bouncing away, so used the old board I had found which was actually a newer soft start version with 3 relays and it worked lovely……… until I put the case on and got the owner out to demonstrate. Lift decided to just sit there motor stall!
Time to return into the darkest depths for some new start and run capacitors me thinks – I know I have some somewhere, just been a few years since I’ve needed some. -
Don’t think it will be the caps, relays probably bouncing either because of a bridge rectifier fault (faulty pcb) or because of resitance up to the push feed if in both directions (lift wiring switches).
Motor can be tested by connecting blue wire to neutral and just one of the brown wires to live – to reverse disconnect brown and connect the other. Make sure loose wire is insulated though.
