Master

Control Relay

A hard-wired master control relay (MCR) provides a reliable means for emergency controller shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom head push buttons are wired in series so that when any of them opens, the master control relay is de-energized. This removes power to input and output device circuits. Refer to the figure on page 1–5.

ATTENTION: Never alter these circuits to defeat their function, since serious injury and/or machine damage could result.

Important: If you are using an external dc output power supply, interrupt

the dc output side rather than the ac line side of the supply to avoid the additional delay of power supply turn-off.

The external ac line of the dc output power supply should be fused.

Connect a set of master control relays in series with the dc power supplying the input and output circuits.

Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it. If you mount a disconnect switch inside the controller enclosure, place the switch operating handle on the outside of the enclosure, so that you can disconnect power without opening the enclosure.

Whenever any of the emergency-stop switches are opened, power to input and output devices should be removed.

When you use the master control relay to remove power from the external I/O circuits, power continues to be provided to the controller’s power supply so that diagnostic indicators on the processor can still be observed.

The master control relay is not a substitute for a disconnect to the controller. It is intended for any situation where the operator must quickly de-energize I/O devices only. When inspecting or installing terminal connections, replacing output fuses, or working on equipment within the enclosure, use the disconnect to shut off power to the rest of the system.

Important: Do not control the master control relay with the controller.

Provide the operator with the safety of a direct connection between an emergency-stop switch and the master control relay.

Using Emergency-Stop Switches

When using emergency-stop switches, adhere to the following points:

• Do not program emergency-stop switches in the controller program. Any

emergency-stop switch should turn off all machine power by turning off the master control relay.

• Observe all applicable local codes concerning the placement and labeling

of emergency-stop switches.

• Install emergency-stop switches and the master control relay in your

system. Make certain that relay contacts have a sufficient rating for your application. Emergency-stop switches must be easy to reach.

• In the following illustration, input and output circuits are shown with

MCR protection. However, in most applications, only output circuits require MCR protection.

The following illustrations show the Master Control Relay wired in a grounded system.

Important: The illustrations only show output circuits with MCR

protection. In most applications input circuits do not require MCR protection; however, if you need to remove power from all field devices, you must include MCR contacts in series with input power wiring.

Using Surge Suppressors

Inductive load devices such as motor starters and solenoids require the use of some type of surge suppression to protect the controller output contacts. Switching inductive loads without surge suppression can significantly

reduce the lifetime of relay contacts. By adding a suppression device directly across the coil of an inductive device, you will prolong the life of the switch contacts. You also reduce the effects of voltage transients caused by interrupting the current to that inductive device, and prevent electrical noise from radiating into system wiring.

The following diagram shows an output with a suppression device. We recommend that you locate the suppression device as close as possible to the load device.

Suitable surge suppression methods for inductive ac load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor, all shown below. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device. See the table on page 1–9 for recommended suppressors.

RC Network

If you connect a micro controller triac output to control an inductive load, we recommend that you use varistors to suppress noise. Choose a varistor that is appropriate for the application. The suppressors we recommend for triac outputs when switching 120V ac inductive loads are a Harris MOV, part number V175 LA10A, or an Allen-Bradley MOV, catalog number 599-K04 or 599-KA04. Consult the varistor manufacturer’s data sheet when selecting a varistor for your application.

For inductive dc load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge suppressor can also be used. See the table on page 1–9 for recommended suppressors.

As shown in the illustration below, these surge suppression circuits connect directly across the load device. This reduces arcing of the output contacts. (High transient can cause arcing that occurs when switching off an inductive device.)

Safety Considerations

Safety considerations are an important element of proper system installation. Actively thinking about the safety of yourself and others, as well as the condition of your equipment, is of primary importance. We recommend reviewing the following safety considerations.

Disconnecting

Main Power

ATTENTION: Explosion Hazard — Do not replace components or disconnect equipment unless power has been switched off and

the area is known to be non-hazardous.

The main power disconnect switch should be located where operators and maintenance personnel have quick and easy access to it. In addition to disconnecting electrical power, all other sources of power (pneumatic and hydraulic) should be de-energized before working on a machine or process controlled by a controller.

Circuits installed on the machine for safety reasons, like overtravel limit switches, stop push buttons, and interlocks, should always be hard-wired directly to the master control relay. These devices must be wired in series so that when any one device opens, the master control relay is de-energized thereby removing power to the machine. Never alter these circuits to defeat their function. Serious injury or machine damage could result.

Power Distribution

Power Considerations

There are some points about power distribution that you should know:

• The master control relay must be able to inhibit all machine motion by

removing power to the machine I/O devices when the relay is de-energized.

• If you are using a dc power supply, interrupt the load side rather than the

ac line power. This avoids the additional delay of power supply turn-off. The dc power supply should be powered directly from the fused secondary of the transformer. Power to the dc input and output circuits is connected through a set of master control relay contacts.

Periodic T

Any part can fail, including the switches in a master control relay circuit. The failure of one of these switches would most likely cause an open circuit, which would be a safe power-off failure. However, if one of these switches shorts out, it no longer provides any safety protection. These switches should be tested periodically to assure they will stop machine motion when needed.

The following explains power considerations for the micro controllers.

Isolation T

You may want to use an isolation transformer in the ac line to the controller. This type of transformer provides isolation from your power distribution system and is often used as a step down transformer to reduce line voltage. Any transformer used with the controller must have a sufficient power rating for its load. The power rating is expressed in volt-amperes (VA).

Power

Supply Inrush

The MicroLogix power supply does not require or need a high inrush current. However, if the power source can supply a high inrush current, the MicroLogix power supply will accept it. There is a high level of inrush current when a large capacitor on the input of the MicroLogix is charged up quickly.

If the power source cannot supply high inrush current, the only effect is that the MicroLogix input capacitor charges up more slowly. The following considerations determine whether the power source needs to supply a high inrush current:

our Controller

• power-up sequence of devices in system

• power source sag if it cannot source inrush current

• the effect of the voltage sag on other equipment

If the power source cannot provide high inrush current when the entire system in an application is powered, the MicroLogix powers-up more slowly. If part of an application’s system is already powered and operating when the MicroLogix is powered, the source voltage may sag while the MicroLogix input capacitor is charging. A power source voltage sag can affect other equipment connected to the same power source. For example, a voltage sag may reset a computer connected to the same power source.

Loss of Power Source

The power supply is designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called “program scan hold-up time after loss of power.” The duration of the power supply hold-up time depends on the type and state of the I/O, but is typically between 20 milliseconds and 3 seconds. When the duration of power loss reaches this limit, the power supply signals the processor that it can no longer provide adequate dc power to the system. This is referred to as a power supply shutdown.

Input States on Power Down

The power supply hold-up time as described above is generally longer than the turn-on and turn-off times of the inputs. Because of this, the input state change from “On” to “Off” that occurs when power is removed may be recorded by the processor before the power supply shuts down the system. The user program should be written to take this effect into account.

Other Types of Line Conditions

Occasionally the power source to the system can be temporarily interrupted. It is also possible that the voltage level may drop substantially below the normal line voltage range for a period of time. Both of these conditions are considered to be a loss of power for the system.

Preventing Excessive Heat

Controller Spacing

For most applications, normal convective cooling keeps the controller within the specified operating range. Ensure that the specified operating range is maintained. Proper spacing of components within an enclosure is usually sufficient for heat dissipation.

In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure. In this case, place blower fans inside the enclosure to assist in air circulation and to reduce “hot spots” near the controller.

Additional cooling provisions might be necessary when high ambient temperatures are encountered.

Important: Do not bring in unfiltered outside air. Place the controller in an

enclosure to protect it from a corrosive atmosphere. Harmful contaminants or dirt could cause improper operation or damage to components. In extreme cases, you may need to use air conditioning to protect against heat build-up within the enclosure.

The following figure shows the recommended minimum spacing for the controller. (Refer to appendix A for controller dimensions.)
