new timer relay help needed

I just puchased a new timer relay Midtex 658-44 with variable on and variable off delays

I want to run the load on for a few seconds every few minutes so I want to use configuration 6 on the document.

ftp://parts: snipped-for-privacy@divxdude.dyndns.org/midtx658.pdf

u may need to use a ftp client to retrieve it.

I'm not real electronics savy anf am really confused by the insructions facts that

config 6 shows 2 sperate sets timer inputs (4 pins) pinout diagram(8-pin "Wiring") does not provide 4 points for

2 sperate timers

config 6 also shows 3 relay symbols 2 which are in K-1 ( B is used for load )

anyway..if I were to guess at it..

8 pins numbered clockwise starting bottm-left of the octal "notch" looking from bottom (right?)

  1. jumper pin 3 to pin 2

2 jumper pin 1 to pin 5

apply input power A to ( pin 1or 5 ) and input power B to pin 7 load is powered by {(switched) pin 4} and {input power B}

how'd i do? guessed right or not? if not please correct me.

thanks for your help.

I left one out (step 3) ..sorry.

  1. jumper pin 3 to pin 2
2 jumper pin 1 to pin 5
  1. jumper pin 8 to pin 2

apply input power A to ( pin 1or 5 ) and input power B to pin 7 load is powered by {(switched) pin 4} and {input power B}

Diagram 6 is not what you want. The 658-44 has switches on it to set the timing for both on and off - diagram

6 uses two separate relays to accomplish that. Look at the diagram below.

The relay coil is connected to pins 2 and 7. You apply a voltage to those pins to energize the relay. You connect your load to pins 1 and 3. Alternatively, you could connect your load to pins 6 and 8.

You set the switches on the relay to conrol the cycle time.

Diagram: (N is the notch, you are looking at the pins - each number corresponds to a pin)

...5...4 ..6.(.).3 ..7..N..2 ...8...1

from bottom or top? the socket i picked up at a surplus store is clockwise from bottom view (opposite your diagram)

It doesn't matter - I probably "drew" the socket backwards, but it doesn't change the wiring. Your socket is like this:

....4...5 ..3.(..)..6 ..2..N..7 ....1...8

The wiring description remains the same: The relay coil is connected to pins 2 and 7. You apply a voltage to those pins to energize the relay. You connect your load to pins 1 and 3. Alternatively, you could connect your load to pins 6 and 8.

ok Ed thanks for the help, much easier than i made it out to be. yeah the pinout is symetrical so even if my way is the wrong one its just means the off period would engage before the on I guess. I wire it up and give it a try.
