Question about Intermatic & Indoor/Outdoor Rain Tight Timer

1 Answer

An apartment complex where I do maintenance has intermatic outdoor timer, a very simple mechanical timer . It keeps good time tabs are set for off and on and yet sometimes the lights are on past the off setting. I suspect weekend tampering because 2 timers had the same problem monday . I can see 1 going bad but 2 at the same time thats like all your sparkplugs going bad at once. Anyway if it wasnt tampering what could it be? I pulled the "off tabs" out and they arent worn, clock keeps time. What else is there?

Timer pins make physical contact with a metal lever that has a bit of grease. When the metal lever is pushed far enough by the pin it clicks into 'on' or 'off' position. The lever moves a slider on back of timer. The slider pushes and pulls the brass-copper contacts located on back of timer.

The metal lever is connected to manual override. So the manual override changes position with each on-off function.

1) When you click the manual override back and forth, is it loose? Or does it snap crisp and clean with no play? This would tell the general condition of the lever mechanism.

2) It seems the pins are a softer metal than the metal lever ... but if the metal lever is worn, the pins might slip past without turning off lights. You can watch the turn-off sequence and see what happens.

3) The contacts on back of timer are pushed together and pulled apart by the slider, so burned points would not cause the lights to stay on ... unless the stop that holds the stationary contact is somehow broken. You would have to take timer out of box and click it back and forth to see what the contacts are doing.

My HB31R runs slow. Is there any adjustment ability to the timer mechanism to achieve a correct 24 hour timer.


http://www.intermatic.com/products/timers/consumer%20outdoor%20timers/electromechanical%20timers/hb31r.aspx

HB31R heavy duty 1800 Watt outdoor plug-in timer is one-piece unit that does not come apart for repairs.

Usually with these mechanical dial timers, when the clock motor starts getting weak, the timer dial starts to stall when tripper meets on-off lever.
And then timers runs slow.
At this point, the little plastic gears are getting stripped out, or the clock motor is overheating.
In either case, the clock motor is spiraling downward.

If this is new timer, take it back.
If this is older timer, the manual and fact sheet do not show a warranty.
New HB31R on ebay for $15

Woods makes 1200 Watt outdoor timer, but lighter weight than Intermatic:

With larger heavy duty outdoor timers like the Intermatic T-101R outdoor 120Volt timer, you can buy the clock motor separate and replace when clock goes bad. And you can buy the trippers separate. However T100 series timers are not plug-in, they are hard-wired. T-101 is made to last 10-15 years, but cost $60-70. My local Lowes sells them in stock for less.

Need manual to set timer


You posted under T-100 series outdoor timer
If you have different timer, add a comment with timer model number located inside cover.

T-104, T-103, T-101 timer manuals show on following page:
If your timer has R suffix, like T-101R, that means box is Raintight for outdoor use.
T-101R and T-101 mechanisms are identical except for box. T-101 box is indoor use.
Click model number and drop-down menu reveals link to manual
http://www.intermatic.com/products/timers/mechanical%20time%20switches/24%20hour%20dial.aspx

If you need simple wiring diagrams, and explanation for each T-104, T-103, T-101 timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

Here's how to set Intermatic T100 series timers:
Lift and rotate yellow dial until current time lines up with silver pointer.
Silver pointer is stationary at 6 o'clock position.
Put ON-OFF trippers on dial at times you want ON OFF functions.
Minimum on-off is 1 hour because of tripper width.
If timer is not working, add a comment and we'll troubleshoot.

These timers have replacement trippers and clock motors at Grainger
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

How timer works:
Clock motor, located on back of mechanism, rotates yellow dial.
Trippers on dial push lever that turns power ON and OFF.
Off tripper pushes lever one direction.
ON tripper pushes lever opposite direction.
When lever is pushed, manual override lever clicks back and forth with audible click sound.

Maybe the jammed pin tore up the plastic gears on the timer clock. You can buy the clock for around $16

BRINKS 42-1014 OUTDOOR ANALOG TIMER


I don't have an instruction manual but there's not much to know. Set the on/off times by depressing the white and grey tabs just above the hour notation for the times you want. If the tabs are up then the power is off. If they are pressed in then power's on. Plug it in, turn the dial to the current time and attach a device using less than 500 watts and you're good to go.

On the model that I have you set the time by pulling the dial out and turning it to the current time.  If it does not "seat" fully when you release the dial it will not engage teh timer gear.  Make sure it is seated by trying to move it slightly in both directions.  If it turns frely it is not seated.  If there is some resistance (don't force it) then it is seated and should keep correct time.  If you have moved the manual lever to the ON position and the lights still do not work you need to make sure the power to the time clock is live.  The timer motor (and the lights) will not work if the power supply is off.  If the power is on and the lights still aren't working on Manual then there is a problem beyond the time clock (broken wire, burned out bulbs, etc.).
