110 VAC 60 cycle Electric Timer

I have a 110VAC 60 cycle timer made by Bliss-Eagle Signal out of Davenport, Iowa. It says Cycl-Flex on the face of it. It's a 0-30 minute timer. It is a Type HP55A6 and Model 4D68. The Patent number on it is D189917. The Patent date is 3/21/61 and it was filed 2/25/59 with Ser# 54737. It was a 14 year patent. I tried to find it on the (US Patent and Trademark Office web site). All it showed there was a drawing of the timer unit itself (no schematic or instructions).
I figured out the layout of the contacts, but I'm not real sure about where to hook up the controls. There's some printing on the back of the timer that shows the contacts and the motor controls, but the motor control part is confusing without the instructions. I don't want to take a chance of hooking up the 110 volts incorrectly and ruining the timer.

SOURCE: Low voltage only or can timer be used for 110 v

The specs you wrote above are for high voltage.

125 vac = 125 volts alternating current = high voltage
250 vac = 250 volts alternating current = high voltage

110 v = 110 volts alternating current = high voltage

110 v is just another name for 125 vac -- it's called the "nominal" voltage.

So, the answer is yes, this timer can be used for "110 volt lights".

A 60 watt incandescent bulb pulls 1/2 amp when connected to 120 volts -- the spec for your timer looks like is 20 amps @ 125 volts tungsten (tungsten is the filament in incandescent light bulbs) --

I say looks like 20 amps because it's not clear which amperage goes with which voltage. Here are both calculations:

- 10 amps divided by 1/2 = 20 bulbs

- if it's 20 amps: 20 amps divided by 1/2 = 40 bulbs.

SOURCE: C8835 Intermatic Timer, 30 Minute

Intermatic C8835 is 120Volt 30-minute cycle timer, which repeats same timing cycle every 30 minutes.
Timer has NO and NC terminals.
You will not use the NC normally closed terminal for this application, so no wire will connect to far left NC screw.

Green wire on green screw is correct, so you have started off well.
Bare copper wire also connects to green screw, so no more talk is needed about ground wires.

If you are using 240V or 277V, then add a comment and we'll lay out a plan for that wiring.
Wiring below is for 120V only.

You have 2 120Volt cables.
1) One cable comes from circuit breaker and has 1 black and 1 white wire.
The black 'line' wire connects to 'switch common' terminal, which is 3rd screw from left.
The white 'neutral' wire connects to 'clock' terminal, which is 4th screw from left.

2) The second cable goes to coal stoker, and has 1 black and 1 white wire.
The black wire connects to Normally Open or NO terminal which is 2nd screw from left.
The white wire connects to Clock terminal, which is 4th screw from left.

Notice that both white wires connect to same screw.

Is there a way that i can make it advance accurately?

Make sure timer is rated same Hz or cycles as your electric power.
Look at product rating sheet or label.
US and Americas have 60 cycle power generation, and the generator spins at 60 revolutions per hour... other areas of the world have 50 cycles
Buy brand name timers where the company is on the internet and shows the product... such as Intermatic, Woods etc

2) Eagle tech support:

3) Fixya appears on 1st page of google search for this product, indicates there is no clear information available on the web.

4) Add a comment and describe the wiring diagram that appears on side of device.
Each pin timer has wiring diagram.
The image I found shows 11-pin base, and push button or impulse input connects to terminals 2 and 6. Image is not clear enough to determine more information.

How do I program the H5CX ASN timer to turn on 5 mins and off 25 mins in an endless cycle. I don't understand the term Output Mode so from that point the instructions become meaningless.


I believe you have 230Volt 50 Hz electric power.
Omron is rated 50-60 hz
US timers are rated 60 Hz.
Maximum load on Omron timer is 5amp at 230 volt
Timer should be connected to 2-pole contactor (relay) instead of directly connected to pump.

Does Amazon sell percentage cycle timer in your country?
A cycle timer makes one full revolution each hour, or 4-hours, or 12 hours. Then percentage is set for 8% for 1 hour cycle.
Contact Intermatic and ask if they have 50 cycle percentage cycle timer, or ordinary cycle timer in 50 Hz.

Everytime I put the pre-sets for the timer, it does'nt keep time. COuld you assist me or provide me with someone who can repair?

I can assist you.

The 'pre-sets' are confusing.
Do you mean tabs or trippers?

Tork 8601 is a 60 minute cycle timer.
The dial should make 1 full revolution each 60 minutes.
Trippers or tabs located on dial are pushed up or down to set on-off schedule.

If dial is running slow, then clock motor has gone bad.
If dial is running on time, then trippers are worn down or timer parts are worn down.
Either case when timer stops functioning, buy a new timer for $110.
If the clock motor was available, you'd probably spend $60 for the motor.
Same Intermatic timer is C8865 for $88.35

I have the same school bell timer, but the bell seems to run on 50 second minutes instead of 60 seconds!

If you have old timer, a new one is probably required, especially if it has gotten wet or dirty.
If you have electronic timer, then it has gone bad.

If you have new mechanical timer ... I wonder if you have a 50 cycle clock motor? Look at the label on timer and it should show the cycles.

Electricity is actually a wave, or a cycle. When the cycle is shortened, the motor runs faster. Occasionally, 60 cycle mechanical timers controlled by electronics also run fast by 1 hour each two weeks.

All appliances and timers and clocks and motors on the shelf are 60 cycle to match electric production in the US.

I own a kenmore top loading machine model number 110 10 amp 60 hertz 120 volts the machine gets power and runs but the big control knob that controls the diffrent cycles is running only about 20 seconds...

sounds like you should replace timer (big control) timer motor is part of timer. Is timer knob speeding thru cycle that fast or just start/stop.
110 is manufacturer code for whirlpool, number after decimal is model number. tech sheet avail inside console by unsnapping left and right console covers and removing hidden screw at front bottom corners, pull forward slightly then fold console back (hinged at rear top).

Dryer Timer running very slow

1st of all make sure you have 110vac to the timer motor, usually the 2 black wires, if you do and the timer won't advance then you do have a bad motor and you would have to replace the whole timer. If you do not have 110v to the timer motor, try selecting the Timed mode. If it advances in the timed mode then the problem isn't the timer, the problem could be poor air flow( plugged up vent or blower wheel) causing dryer to cycled off of the limit and not the thermistat which is how most auto modes work. Good Luck

Low voltage only or can timer be used for 110 v

1 hp= 750 watts
125 vac = 125 volts alternating current, wall outlets
5 amp= 5amps

125vac x 5amps= 625 watts

a timer is a switch with a clock on it. just like a switch in a lamp cord.

What are your power requirements? I lived in Europe for a while and all the appliances ran on 220 VAC, 50hz. Most American appliances that use 220 VAC (like dryers and electric ranges) have 60hz timers, clocks and motors. Now...if the European standard is still true (I haven't been there in years), you can probably use your dryer, but the timing will not be accurate. Your timer will probably run slower than required.
