defrost timer problem.

[lurgi]

Can anyone please tell me the difference between an 8145-20 and an 8145-20ex defrost timer (paragon).
I fitted the 20ex in place of the 20 and it wouldn't work-even though they look identical to the eye.

WHat's the difference and how can I make it work please?

8145-20 Defrost 240v, 1-3 open 2-4 closed 40 amp, press/term Try ck the swithes

thankyou.

The 8145-20ex is an export only model, it is basically a relabeled 8145-20. Functionally, they are identical.
Paragon's quality has been going downhill in the past few years. The new timers don't seem to last as long as they used to. They are occasionally bad right out of the box. It is usually that the drive motor doesn't want to run properly. I used to swear by Paragon, but I am going to start "auditioning" replacements.

im anxious to see how their new dual voltage electronic clocks hold up. They claim they are far superior to the standard ones. Contact points are suppost to last like 16 times longer.

The contacts were never really a problem. The main problem is with the gearmotor that drives the clock mechanism. They have become unreliable. To the point of being far more than coincidental failure. Something has been changed, whether it is in design or materials, I don't know. I guess it comes down to the material and labor are supplied by the lowest bidder.

BUT, the clocks don't seem to be any less expensive!

I havr found that supco makes a great defrost timer w/ electronic timing and relays. Model EDT-12, EDT-13 will replace about everything out there and even fit in the old time clock box. These work best when they are pilot duty(controling a solenoid or a small load under 1 hp) and they are 1/3 price of a new paragon.

The ex model is for export. It should not show up in the U.S. The model is identical to the U.S. models and should work. As far as comments about gears, the gears are still machine hobbed, no change. The motors may be an issue. I have seeen the cap rotor impeding rotation in the field and have reported this to the factory,... years ago.

As far as the relays, I am not aware of any changes. These are supposed to be the same silver coated copper relays as in the past.

I will note that I have heard of full amperage applications that have had some problems. I recommend a $5 contactor if the amperage is above 20A.

Any other field comments are welcome, they will go straight to marketing an engineering.

I am outside the US, and sometimes receive the EX model for installation. I have seen too many failures as of late, to believe that it is coincidental. We have recently recorded failures on a 1 week old clock installed on brand new produce cases, a three week old factory installed clock installed on a Russell unit installed on an ice cream freezer, and on a self contained salad bar. These examples spring to mind, but we seem to be going through timers faster than ever before.

After paying freight charges and 42% import duties I have to look at alternatives. I can't sell an unreliable product, because in the end I stand behind the work, and I therefore occasionally have to eat the cost of the clocks. In my case, it is not feasible to return a defective clock to my supplier.

it would be nice if all the things that used to be made in america was brought back here..i worked on a bevair beverage box that was still on the pallet and broke..made in pakastain....

Guys,

I have been reading through this thread and am alarmed. I have been hearing through the grapevine that we were having a problem with the timers. My issue is that we haven't been getting any of the failed units returned to figure out what is going on.

I am wide open to suggestions on how I can get these back. I absolutely cannot afford to have these problems fester. This product has been too good for too long. We want to correct the problems and need your help. I welcome your calls, emails or posts.

nice to see a company be pro-active for a change. rather than the same old "we dont have probs. with our product blah blah blah"
way to step up invensys!!!

1. invensys The ex model is for export. It should not show up in the U.S.


1. I ,m on the east coast southeast va northeast nc the ex is all i can buy lately. my suppliers re michaels, ars ,united ,airco



2. The model is identical to the U.S. models and should work. As far as comments about gears, the gears are still machine hobbed, no change.

2. it works but i,m changing a lot this year as well the reason i don,t return them is my custemer just wants thier box to work they don,t care whats wrong and i get paid to sell another clock


3. The motors may be an issue.
I have seeen the cap rotor impeding rotation in the field and have reported this to the factory,... years ago.


3. the motor is the only issue i,ve seen the relays are always ok unless 10-15 year old equip.


4. As far as the relays, I am not aware of any changes. These are supposed to be the same silver coated copper relays as in the past.
I will note that I have heard of full amperage applications that have had some problems. I recommend a $5 contactor if the amperage is above 20A.


4. I do alot of electric defrost always use properly sized contactor if needed no problem there

thanx for listening hope y,all figger it out have used parragon since the 70,s

Dan I have also seen a great rise in Motor failures on your clocks. Mostly they get tossed and a grasslin installed now due to the quality of the clocks. I have yet to have a grasslin fail if used on a pumpdown system, grasslin clocks dont like the 100 amp LRA when a compressor decides not to start.
