Autonics Fx4 Counter Wiring with Direct Online Starter | Proximity Sensor Diagram

This post is about the autonics fx4 counter wiring with a direct online starter and proximity sensor with a complete diagram. In the post I showed a diagram of complete wiring of direct online starter with mccb circuit breaker, magnetic contactor, thermal overload relay or 3 phase motor protection relay, Normally open push button switch, normally close push button switch, fx4 counter and proximity sensor with complete wiring connection.
The wiring is divided into two parts. main wiring and controlling wiring. First I will talk about the main wiring which is about wiring for the 3 phase induction motor. And the 2nd wiring is controlling of direct online starter with Autonics fx4 counter with the proximity sensor.

Autonics Fx4 Counter, Proximity Sensor Wiring With Direct Online Starter Diagram

First, see the autonics fx4 counter connection with a direct online starter diagram. Then I will explain step by step...

Autonics fx4 counter with dol starter and proximity sensor diagram

In the above counter with the dol starter diagram. The 3 phase supply L1, L2, L3 (red, yellow, blue) is connected to the MCCB (molded case circuit breaker). After the MCCB Circuit breaker, the main supply is connected to the magnetic contactor main terminals. And after the contactor, the 3 phase supply goes to the thermal overload relay. After the thermal overload relay, the 3 phase supply goes to the 3 phase induction motor. The earth connection is also connected to the 3 phase motor.

Control Wiring Of Autonics Fx4 Counter For DOL Starter with Proximity Sensor

The magnetic contactor and fx4 counter will work on 220 VAC. It means that we also need a neutral wire. So first of all connect the neutral wire to the NC terminal of the thermal overload relay. if you connect it to 95 terminal then get supply to from the 96 terminal. After that provide the neutral wire to the contactor A1 coil terminal and counter 9 terminal. As I showed the neutral wire connection with black color in the above diagram. After getting the line supply from one of the above lines. I get the Line wire from the L3 which you can see in the above diagram. The line wire is shown in red color. The line wire is connected to the normally close push button switch. After that, the wire goes to the normally open push button switch. From there a  red color wire goes to the Normally open auxiliary contacts for the magnetic contactor. This is called hold current wire.
After that, the holding wire will go from the other side of the auxiliary contact and connect to the counter 1 and 2 terminal.
From the normally open push button switch, a blue color wire will connect to the counter 3 terminal and contactor A2 coil terminal. This is called touch or starting current wire.

That is all. Soon I will upload a video about the autonics fx4 counter connection with direct online starter and proximity sensor working video and diagram explanation video.

  1. Aw, i thought this was an incredibly good post. In thought I would like to invest writing such as this moreover – taking time and actual effort to have a top notch article… but exactly what can I say… I procrastinate alot and by no means apparently get something done.

  2. This is the system i used to build an Auto timer but on a single phase.
