Wiring Two Relays to Replace Momentary Rocker Switch on Hoist Pendant Control

Hi A pendent remote connected to an electrical hoist.  There is one momentarily rocker switch on the pendent; while pressing the rocker switch on the left or right, motor rotates up and down direction accordingly.I like to replace the rocker switch with two relay switches, one to connect the up and one connect info down circuit.Please help me to confit what type relay I should use and how it should be wired.  Below is wiring diagram for the pendent and the rocker switch:
Thank you

Jamal I answered your question on this hoist previously here:https://www.eeweb.com/forum/interfacing-hoist-remote-control
Is that not going to work, did you try that, did you have problems?
There are two aspects to selecting suitable relays:1. What power is available to operate the relays (I previously assumed 110VAC)2. What current carrying capability do the contacts need?  This will depend on the hoist motor).You need to have safeguards in place to avoid operating both contacts at once - that will cause a short circuit / lots of sparks / blown fuses / melted relays / etc....If you need further assistance let me know and I will try and advise further.

Hey DavidThanks for quick response, Well  on my trip back home,  I found that what I was  trying build was being used commercially. So I thought it would easier to use already wired control box instead of building one  from scratch.So  I had ordered a control box made for my use right before I left.  I got the control box 2 weeks  ago.The control box  comes with two set of wired soft touch keys and one wireless switch that can control the motor from two different locations.  On the control box, there are  two input terminals to power it up and 8 output terminals as follow:2 terminals to power the electric motor 2 terminals to control rotation of the motor2 terminals to connect up and down limit switches 1 terminal for emergency stopWhat I realized was that unlike   the  motor back home electrical  motor I got has only 3 input wires (2  capacitors connected in parallel are connected in series to one of the wires); despite trying all sorts of  configuration to replicate 4 wire connect, I had no success, I only hear humming noise from the motor   when I press up or down buttons, motor doesnt turn at all!So I got an idea, tested  left and right output terminals with the neutral terminal, I observed that 110v voltage present when up or down buttons press.Now if I connect those terminals to two relays that are connected to pendent’s up an down circuits this configuration meets my needs.The control box already has the limiting switches terminals. So when I press up or down keys respective control rotation terminal will have voltage that could turn on the relay. I don’t know what type of relay I need; how many pins should it have to connect up and down circuits; and lastly how to wire connect these relays to respective up and down circuit on the pendent.Sorry for long story, hope you can help with this one as well.
Cheers!

Jamal have you got a link to the data sheet or instructions for the controller you bought?  I hesitate to advise you on this without knowing how it works.  I suspect the capacitors inside the controller are meant to replace the capacitor in your original circuit... but without more information I cannot be sure.
Thanks // David

Dave there is no capacitor inside control box Only two connectors wired together and a receiver for wireless switch.Unfortunately this was done by a small shop, no data sheet provide.

Hi Dave, Attached are  a few pictures of the control box.Below is the control unit and push button key pad that goes with it.Above picture shows the output terminal of the control box, first two terminal are supposed to connect to motor directly and the second pair are supposed to control motor rotation.On the right side of the box are the terminals to connect limiting switches for up and down direction.  There is also an emergency stop terminal on the side of the box.
Ideally, I like to connect the motor directly to these 4 terminals and operate the motor rotation.  If that is no possible,  I thought to use the up and down terminals to power up two other  relays  that are connected to pendant wiring and control the motor rotation.  This ways I still could connect limiting switches to yellow control box.Voltage is 110VCurrent is 7.1 Amp3/4 HP motor
Please Help!
Thanks, 

these are the connectors and wireless receiver in the control boxabove picture show the input power to the unit

Jamal with a  wiring diagram of the box I could maybe help you more.But you could try relays on your up and down wires as followsyou would need relays with 110V AC Coil, 10A or more current carrying capability, and two make contracts on each relay.  Contactors would be OK, better in fact.You could try wiring them as follows into your existing remote wiring:
The Blue, Red, Black and White wires to the contacts are from your existing rocker switch control pendant, and the down / up / common wires are to your new controller.

Thank you DaveI will give this a try this week and let you knowCheers!
