Ok all

We are experiencing intermittent shutdowns on an elevator with Swift 5000 Controls. We have no monitor in place to help assess faults, but do have a laptop with only gives us fault codes, which we can then interpret from the documents in the machine room. Here are a list of faults we are getting and a brief description of what we have done. After completing all the below we continue to get intermittent faults.

Fault 11: Limit Position Reference Error: Replaced the power supply, new terminal limit at basement level

Fault 43: Gate and Lock Limit: Installed new gate contacts

Fault 31: Car in next up mode:

Fault 18: Car Response Time Out: Replaced Module, Replaced BK Relay, replaced MC Relay, replaced BK Module

Fault 27: BK and MC relay; replaced both relays

After all of the above we are still experiencing intermittent shutdowns. Floors served B, 1-15.

A modernization of this elevator (as well as all others) is currently in the works, however, at a minimum of 6 months out

Can anyone help with the above issues?

Secondly, does anyone know if there is a auto call mode on this type of control system where we can block the doors from opening, and run the car without the doors opening?

Your help is greatly appreciated

It's been some time since I looked at any of these controllers. On a unit this old I would go over it with a fine toothed comb. First I would check all your door locks. I would run the length of the shaft on inspect and check my clearances. If your clearances are good, how do the contacts look? If they are worn I would replace them. Second, Look at why your DPC is off when coming into the terminal floor.

As far as running and not allowing the doors to open, all the swift cars I worked on had a toggle switch for that purpose.

Jk is correct. I believe on the 5000 there are rotary type knobs to do certain functions i.e. shut down the CPU, Inspect or place the car on "Door Disconnect" (Test?), or maybe even taking the car out of the group. The feature you're looking for is Door Disconnect. Once this is active, the tool will say "Door Disconnect" where it would normally say, "Automatic". Run it all day long without the doors. I'd look at the selector guides for wear. Kid you not, I had an Futura job where 3/16ths" (total play) wear on the nylon guides would give me DPP errors because the selector tape had straight holes rather than elongated. If the 5000 selector has LEDs for DPP1 and 2, run the car on cartop inspection, watch the LEDs toggle on and off. Push the selector box back and forth to see if there is any miss in toggling of the LEDs. Another area of trouble is simply broken/loose wires at the termination points on those Spretcher Shue relays.

The rotary switch is to use the LEDs to view the PMI I/O's the number on the dial correlates to PMI board.

if you changed the limit, verify its position. You could increase LPE, but that should only be done for testing since it allows an error in the count. Verify your DOL and DCL too. if you make up a door lock too soon, the timer is looking for the gate, the lock then the DCL, in that order all within a short amount of time (+/- 300 ms). More issues are caused by a real slow final door close speed or a real wide gate switch. You mentioned the power supply, what did you see on the old one? you should have a good 24 vdc, but no one ever checks the AC component riding on the DC. While measuring the DC, switch meter to AC, I don't get concerned until over 25mv of AC component on a regulated power supply. Lastly, Swifts are really flaky with analog light bulbs/gongs/chimes etc due to them drawing down the dc voltage (2 to 3 volts is not uncommon) and causing the CPU to reboot. Hope this helps.
