When contactor M 1 is energized, the 3 phases (A, B, and C) are connected directly to terminals 1, 2, and 3 of the motor, respectively. However, when contactor M 2 is energized, phases A and B are reversed, A going to motor terminal 2 and B going to motor terminal 1. This reversal of phase wires results in the motor spinning the opposite direction.
A key is used to start the process and remains trapped whilst the machine is running. The only way to remove the key is to isolate the hazard. This key is then used to gain access to the dangerous area and remains trapped in position while the gate or door is opened. The key can only be removed when the gate or door has been shut.

Feb 01, 2016 Disengage ball mill clutch. The mill feed conveyor will automatically stop due to the interlocks between the clutch or cyclone feed pumps and the conveyor. Shut down ball mill motor. Shut down ball mill lube system. Drain and flush the cyclone feed pump, line and pump box if the shutdown is longer than 1-2 hours.
Apr 18, 2018 The Challenge of Replacing Lockout With Interlocks. The eternal battle is production versus safety, and at the very center of this is lockout, or better avoiding lockout. The complaint, by both production and maintenance is that locking out equipment takes too long, or if they lockout, getting the machine back on line could be difficult.
Without a motor starter, interlocked safety guards would stop the machine if opened and start it up immediately after closing the guard. Not only is it hazardous to wire something this way, but it is also a dangerous misuse of the interlock switches. Limit switches and interlock switches are not designed or intended to control motor current loads.
Jul 14, 2010 Safety Features Lid Interlock prevents mill from running if lid is not closed. The latch also prevents the lid from being opened until the clamps come to a stop.

Jan 26, 2021 Jan 24, 2021. 8. T. Connolly said An interlock is a condition or series of conditions that must be met to allow an operation or process to continue. Examples are numerous, but some general examples include shield interlock- the machine cannot run unless all the safety shields are closed. flow interlock - the operation cannot continue unless ...
Mar 06, 2009 9.2.2 Stop Functions. Stop functions shall override related start functions. The reset of the stop functions shall not initiate any hazardous conditions. The three categories of stop functions shall be as follows (1) Category 0 is an uncontrolled stop by immediately removing power to the machine actuators.
So motor will run if start button is pushed, stop button is not pressed, overload relay is not picked and limit switch is closed. Note This post for educational or reference purpose only. For a live circuit, there will be some additions to the above circuit like safety related, as per application, some interlocks etc.

This is called Holding link i.e. it holds the motor in start condition. Now, Motor will still run even we leave (disconnect to stop) the ON-Push 1. A normally open (NO) link is also used in line 2. When M1 energizes, this link (NO M1 in line 2) will be also closed, therefore, M1 Motor will start to run, this way, supply also will reach to ON ...
Dec 30, 2010 Re safety door interlocks. I added an observation port one time. It was a copy of one I saw on a Maho macine too. It was about 12 diameter plexiglass plate attached to a small high speed motor. I cut small through hole to attach the motor and allow the drive shaft to fit through with plenty of clerance.
Aug 10, 2018 W.L. Mostia. Aug 10, 2018. 3. For safety interlocks, the interlock should be True or a 1 if allowed to advance or to permit the action that is interlocked. This way if you lose power in the interlock, you are not allowed to advance (e.g. failsafe). It is always better to indicate a safe state with positive logic.

The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if
