Hopper Loaders with/without Sight Glasses 4

This section includes information on safety devices and procedures that are inherent to the

Controller. This manual is not intended to supersede or alter safety standards established by the user of this equipment. Instead, the material contained in this section is recommended to supplement these procedures in order to provide a safer working environment.

At the completion of this section, the operator and maintenance personnel will be able to do the following:

• Identify and locate specific safety devices.

• Understand the proper use of the safety devices provided.

• Describe the function of the safety device.

Safety Circuit Standards

Safety circuits used in industrial systems protect the operator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment.

Various agencies have contributed to the establishment of safety standards that apply to the design and manufacture of automated equipment. The Occupational Safety and Health

Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the organizations that have joined with the plastics industry to develop safety standards.

Every effort has been made to incorporate these standards into the design of the conveying system; however, it is the responsibility of the personnel operating and maintaining the equipment to familiarize themselves with the safety procedures and the proper use of any safety devices.

Fail Safe Operation

If a safety device or circuit should fail, the design must be such that the failure causes a

“Safe” condition. As an example, a safety switch must be a normally open switch. The switch must be held closed with the device it is to protect. If the switch fails, it will go to the open condition, tripping out the safety circuit.

At no time should the safety device fail and allow the operation to continue for example, if a safety switch is guarding a motor, and the safety switch fails, the motor should not be able to run.

WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air) sources prior to servicing the 2-Pump, 20-Station Controller. Failure to do so may result in serious injury. No one but the person who installed the lockout may remove it.

Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a circuit. The safety devices that are used in this Controller are primarily concerned with electrical power disconnection.

2-Pump 20-Station Controllers 5

1-4 Responsibility

These machines are constructed for maximum operator safety when used under standard operating conditions and when recommended instructions are followed in the maintenance and operation of the machine.

All personnel engaged in the use of the machine should become familiar with its operation as described in this manual.

Proper operation of the machine promotes safety for the operator and all workers in its vicinity.

Each individual must take responsibility for observing the prescribed safety rules as outlined.

All warning and danger signs must be observed and obeyed. All actual or potential danger areas must be reported to your immediate supervisor.

General Responsibility

No mater who you are, safety is important. Owners, operators and maintenance personnel must realize that every day, safety is a vital part of their jobs.

If your main concern is loss of productivity, remember that production is always affected in a negative way following an accident. The following are some of the ways that accidents can affect your production:

• Loss of a skilled operator (temporarily or permanently)

• Breakdown of shop morale

• Costly damage to equipment

• Downtime

An effective safety program is responsible and economically sound.

Organize a safety committee or group, and hold regular meetings. Promote this group from the management level. Through this group, the safety program can be continually reviewed, maintained, and improved. Keep minutes or a record of the meetings.

Hold daily equipment inspections in addition to regular maintenance checks. You will keep your equipment safe for production and exhibit your commitment to safety.

Please read and use this manual as a guide to equipment safety. This manual contains safety warnings throughout, specific to each function and point of operation.

Operator Responsibility

The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations.

Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this manual, or any other safety information will not keep you from being injured while operating your equipment.

Hopper Loaders with/without Sight Glasses 6

Learn and always use safe operation. Cooperate with co-workers to promote safe practices.

Immediately report any potentially dangerous situation to your supervisor or appropriate person.

Maintenance Responsibility

Proper maintenance is essential to safety. If you are a maintenance worker, you must make safety a priority to effectively repair and maintain equipment.

Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric supplies and all accessory equipment at the machine, and disconnect and lockout electrical power. Attach warning tags to the disconnect switch.

Be sure that all non-current carrying parts are correctly connected to earth ground with an electrical conductor that complies with current codes. Install in accordance with national and local codes.

When you have completed the repair or maintenance procedure, check your work, remove your tools. Rigging, and handling equipment.

Reporting a Safety Defect

If you believe that your equipment has a defect that could cause injury, you should immediately discontinue its use and inform the manufacturer.

The principle factors that can result in injury are failure to follow proper operating procedures

(i.e. lockout/tagout), or failure to maintain a clean and safe working environment.

5. Enter the number of minutes (between 0 and 99) that you want the horn to stay off. If you want the horn to stay on as long as the alarm persists, leave the setting at 0. If you want the horn to stay off until a new alarm occurs, enter 99 in the keypad. Use

(Backspace Key) to erase any mistakes. Use (Enter Key) to enter the value. The keypad disappears and the new setting appears under Horn Silence.

Setting Up Pump Staging

To avoid an excessive power demand at your facility when the conveying system starts up, you can stagger the times at which pumps start. Whenever a demand would cause two pumps to start simultaneously, your choice for pump staging sets the delay between the start of one pump and the start of the next. The factory default is a delay of three seconds. You need to change this setting only if this delay is too long or too short for your facility.

To set the delay between the start of one pump and the next, complete the following steps:

1. Go to the “System Setup” screen by touching the Menu button on any screen. Then touch System Setup. The “System Setup” screen will pop up.

2. Touch the Pump Staging button. A keypad pops up.

3. Enter the number of seconds (between 0 and 99) for the length of the delay between the start of one pump and the next. Use (Backspace Key) to erase any mistakes.

Use (Enter Key) to enter the value. The keypad disappears, and the new setting appears under Pump Staging.

Setting Up Touch Switch Delay

During operation, the controller normally displays the “Station Status” screen or the “Pump

Status” screen, showing the current status of all stations or pumps. Briefly touching the icon for a station or pump toggles between taking it offline (disabling it) and putting it online

(enabling it). Touching the icon and holding it takes the user into the controller’s menu system. The setting for button delay determines how long the user must keep an icon touched before a menu appears. The factory default is 1.5 seconds. You need to change this setting only if you find that users are having difficulty with the current setting.

To change the touch switch delay, complete the following steps:

1. Go to the “System Setup” screen by touching the Menu button on any screen. Then touch System Setup. The “System Setup” screen will pop up.

2. On the System Setup screen (Figure 4), touch the Button Delay button. A keypad pops up.

3. Enter the number of seconds (between 0 and 99) for the button delay. Use

(Backspace Key) to erase any mistakes. Use (Enter Key) to enter the value.

The keypad disappears, and the new setting appears under Button Delay.

Finishing Setup: Setting Up Passwords

You can set up passwords for two levels of security: for operators and for setup personnel.

The controller comes from the factory with neither password set. This allows every user access to all functions.

Setup Password

If you define a password for setup personnel, then most settings can be changed only after entering the password. The password will be required to display the following screens:

• System Setup (to review and change system-wide settings, clear the alarm log, and go to the network status screens).

• Station Setup (to review and change settings for all station options).

• Pump Setup (to review and change settings for all pump options).

Operator Password

If you define a password for operators, then a password will be required to carry out any function (other than reviewing station and pump status, silencing alarms, reviewing the alarm log, and looking at help screens). Entering the operator’s password will give the user access to the functions at the following screens:

• Station Status (to enable or disable a station, and start or stop system)

• Pump Status (to enable or disable a pump, and start or stop system)

• Station Operator (to adjust a station’s convey time and dump delay, activate priority convey, and review the station’s last convey time and pump assignment; depending on

Hopper Loaders with/without Sight Glasses 24

the options installed, the screen may also enable the operator to adjust the mix percentage for a remote proportioning valve, review the last purge time and purge valve, and set the intended material line for material proofing).

Entering the setup password will give the user access to all functions.

Note:

If you want to protect the operator’s functions with a password, you must also define a setup password. If you leave the setup password undefined, then all users will have access to all functions.

If you want two different levels of password protection, you must make the passwords different from each other. If the two passwords are the same. Then any user who enters the password will have access to all functions.

To set (or remove) password protections, complete the following steps:

Go to the “System Setup” screen by touching the Menu button on any screen. Then touch System Setup. The “System Setup” screen will open.

2. On the “System Setup” screen (Figure 4), touch the Operator Password button or the Setup Password button, depending on which password you want to set up. A keypad pops up.

3. Enter up to four digits. If you want to remove password protection, enter 0 as the password. Use (Backspace Key) to erase any mistakes. Use (Enter

Key) to enter the value. The keypad disappears, and the “System Setup” screen shows the password you entered.

Note:

When entering a password, all four digits must be supplied. For example, if you enter a password of 2 here, you will need to enter 0002 when the controller prompts for the password.

If desired, you can also change the duration for which a password remains effective. During operation, the password-protected screens are available either until the user logs off or until this time elapses, whichever comes first. This feature prevents the password from remaining active if a user forgets to log off.

Note:

The password timer starts when the user logs on. It expires even if the user is actively using the screens when the chosen time is up. If the timer expires, the system goes to the “Station Status” screen. Your password duration should be long enough to allow authorized users to complete their tasks but short enough to provide adequate protection against tampering.

To change the duration of the password, complete the following steps:

On the “System Setup” screen (Figure 4), touch the Operator Password Duration button or the Setup Password Duration button, depending on which password duration you want to change. A keypad pops up.

2. Enter the number of minutes (between 1 and 99) that you want to set as the password duration. Use (Backspace Key) to erase any mistakes. Use (Enter Key)

2–Pump 20-Station Controllers Installation 25 of 51

to enter the value. The keypad disappears, and the “System Setup” screen shows the new setting.

Once you have finished all the setup described above, you are ready to start the system. To start your system, complete the following steps.

1. At any screen, touch Menu on the right side of the screen. The “Menu” screen appears (Figure 3).

2. Touch Stations. The “Station Status” screen appears (Figure 6).

3. For each station that you want to use, briefly touch its icon. The icon turns blue, indicating that the station is ready, or the icon turns yellow, indicating that the station needs material.

Chapter 4: Operation

4-1 Overview

Your 2-pump, 20-station controller electrically controls valves and solenoids to convey material from a central location to individual stations as needed. The controller senses demands for material at the stations and responds to the demands in a timely fashion.

This section gives the procedures for using your controller, and it covers tasks that can be carried out with no password or with an operator’s password. The section is divided into three sub-sections:

• Basic tasks: tasks normally carried out by a station operator

• Advanced tasks: tasks normally carried out by setup personnel

• Alarms: silencing and clearing alarms

Note:

Before you carry out any of the procedures in this chapter, the system must be set up as described in the previous chapter.

Reviewing Station Status

The starting point for all operations is the “Station Status” screen. To reach this screen from any other screen, touch Menu on the right-hand side of the screen, and then touch Stations.

The “Station Status” screen appears.

Logging On and Logging Off

Your controller may be set up to require a password for any operation (other than reviewing station and pump status, silencing alarms, reviewing the alarm log, and looking at help screens). If so, touching a button will open the “Password Entry” keypad screen.

Figure 15: “Password Entry” Screen

2–Pump 20-Station Controllers Operation 29 of 51

Enter the four-digit password (including any leading zeros). For example, if the password is

1, enter 0001.

Each digit appears as an “X” as you touch it. When you touch the fourth digit, the controller carries out your request. For example, it enables or disables the requested pump or station, or it goes to the “Station Operator” screen. If you did not enter the correct password, the controller erases the entry. You can then try again. To give up, touch Return.

Note:

If you have lost the password(s), contact us for assistance.

Once you have logged on, the password remains active until you log off or the password expires. (Setup personnel at your facility control the number of minutes before the password expires.) While the password is active, you can continue to carry out password-protected tasks without reentering the password. If the timer expires, the controller goes to the “Station

Status” screen and you must reenter the password to continue working.

When you have finished any tasks that require the password, you should log off. (If you forget to do this, the controller will log you off when the password expires.) To log off, complete the following steps:

1. Go to the “Menu” screen by touching Menu from any other screen.

2. Touch Log Off Password. The “Station Status” screen opens.

Enabling and Disabling Stations and Pumps

When a station or pump is disabled, the controller makes no attempt to use it and ignores any alarms that occur for it. Disabling a station or pump at the controller’s screen is similar to bypassing a station with its bypass switch. Enabling a station or pump makes it available for use.

Note:

For a station to be available for the system, it must be enabled at the controller’s

screen and its bypass switch must be in the “0” position.

To enable or disable a station (or pump), complete the following steps:

1. Go to the “Station Status” (or “Pump Status”) screen, if needed. To reach this screen from any other screen, touch Menu and then Stations (or Pumps).

Each disabled station (or pump) has an icon with a status of “offline” (black with a gray outline). All other statuses are enabled statuses.

Touch the icon for the station (or pump) briefly. The station (or pump) switches to the new state, as indicated by the color of its icon.

Note:

If the “Station Operator” (or “Pump Setup”) screen appears when you touch the icon, then you have kept your finger on the screen too long. Touch Stations (or

Pumps) to return to the “Status” screen and try again. If you find it difficult to touch the icon briefly enough, ask the setup personnel at your facility to lengthen the touch switch delay.

Hopper Loaders with/without Sight Glasses 30

Starting and Stopping the System

WARNING! In an emergency, you can use the power switch at the controller cabinet if a password is required to stop the system and you do not know the password.

Note:

Normally, all the stations and pumps you want to use should be enabled before you start the system. When the system is stopped, icons for enabled stations are blue and icons for enabled pumps are yellow. Enabling stations and pumps is described on p. 303.

A button to start and stop the system is located in the lower right of the “Station Status” and

“Pump Status” screens. When the system is off, the button is red and reads Push to Start

System. When the system is on, the button is green and reads Push to Stop System.

Depending on the setup at your facility, the system may prompt for a password when you touch this button.

Note:

If conveying does not begin when you start the system, check to make sure that all needed pumps are enabled. If they are, check that all needed stations are enabled.

Reviewing and Adjusting Basic Station Settings

The 2-pump, 20-station controller has a “Station Operator” screen for each station, as shown below. This screen enables you to review and adjust all basic settings for the station.

To reach the “Station Operator” screen, complete the following steps:

1. Go to the “Station Status” screen, if needed. To reach this screen from any other screen, touch Menu, and then touch Stations.

2. Touch and hold the icon for the station, until the controller either prompts for the password or displays the “Station Operator” screen. Once you have entered the password (if needed), the “Station Operator” screen appears.

Figure 16: “Station Operator” Screen

Settings in the box labeled Convey, the red Priority Convey Activate button, and the menu controls on the right-hand side of the screen appear for all stations. Buttons in light gray are settings that you can adjust at this screen. Boxes in dark gray are for display only. If a pump assignment needs to be changed, this must be done at the “Station Setup” screen.

2–Pump 20-Station Controllers Operation 31 of 51

Navigating Among the Station Operator Screens

The controls in the upper right-hand corner of the screen enable you to move among the

“Station Operator” screens:

• To display the screen for the next lower-numbered station (for example, to move from the screen for Station 15 to the screen for Station 14), touch ◄ Back.

• To display the screen for the next higher-numbered station (for example, to move from the screen for Station 15 to the screen for Station 16), touch Next ►.

• To display the screen for a specific station, touch Goto. A keypad pops up. Enter the number for the desired station. Use (Backspace Key) to erase any mistakes. Use

(Enter Key) to enter the value.

• To exit to the “Station Status” (or “Pump Status”) screen, touch Stations (or Pumps).

Adjusting Convey Time and Dump Delay

Convey time is the length of time the station’s vacuum valve remains open to allow material to be drawn in. (For a volume-fill station, the valve closes when material covers the station’s volume-fill proximity sensor or this time elapses, whichever comes first.)

Dump delay is the length of time allowed for material to drain from the station into its receiver. During this time, the controller does not attempt to deliver any more material to the station.

The settings for convey time and unload time should match the times actually required to fill and empty the station. The following problems may occur if these settings are incorrect:

• Material is backing up and causing “high vacuum” alarms (for time-fill stations only):

Convey time is too long.

• System is not keeping up with the demand for material: Convey time is too short, or dump delay is too long.

For your reference, the “Station Operator” screen shows the length of time the controller actually spent conveying material during the most recent delivery under Last Convey

Time.

To adjust a station’s convey time (or the dump delay), complete the following steps:

1. Go to the “Station Operator” screen by touching and holding a station icon, or go to the

“Station Setup” screen.

Touch Convey Time (or Dump Delay) A keypad pops up.

Enter the number of seconds desired for convey time or dump delay. Use

(Backspace Key) to erase any mistakes. Use (Enter Key) to enter the value.

The new setting appears under Convey Time (or Dump Delay).

Hopper Loaders with/without Sight Glasses 32

Activating and Stopping Priority Convey for a Station

Note:

Before activating priority convey, make sure that all other stations using the same pump have adequate material in reserve to continue operation. No material will be conveyed to these stations during priority convey.

If you want the controller to fill a specific station with material immediately, you can activate

“priority convey” for that station. When you do so, the controller temporarily dedicates the station’s pump to it, ignoring demands from other stations assigned to that pump. Once the chosen station is full, normal operation resumes.

You can also use this feature to give one station a “head start” by conveying a few loads to it and then stopping the priority convey.

No more than one station for a given pump can be in “priority convey” at once. To activate priority convey, complete the following steps:

1. Go to the “Station Operator” by touching and holding a station icon, or go to the

“Station Setup” screen.

2. Touch Priority Convey Activate. The button changes to Priority Convey Active and blinks until the station’s demand has been satisfied (or you stop the priority convey). The controller begins filling the chosen station only (after finishing any conveying already in progress).

3. To stop a priority convey before the station is completely full, touch the blinking

Priority Convey Active button. The button changes to Priority Convey Activate and stops blinking. The controller finishes the current convey, if any, and resumes normal operation.

4-3 Adjusting Advanced Settings

This section describes the procedures carried out during operation that are normally reserved for setup personnel. These procedures require use of the setup password (if your facility has defined one). The procedure for logging on and off with the setup password is the same as for logging on with the operator password; see p.32 for step-by-step instructions for logging on and off.

Reviewing and Resetting a Pump Hour Meter

The controller keeps two meters for the length of time a pump has run. One, like a car’s odometer, keeps a running total and cannot be reset. The other, like a car’s trip odometer, counts the running time since the last reset.

To review and reset the hour meter, complete the following steps:

1. At any screen, touch the Menu, and then touch Pumps. The “Pump Status” screen opens.

Touch and hold the icon for the pump. The “Pump Setup” screen opens.

2–Pump 20-Station Controllers Operation 33 of 51

Figure 17: Pump Setup Screen

The box labeled x Hours Resettable shows the running time since the last reset. The box labeled x Hours shows total running time.

To reset the resettable meter, touch Hour Meter Reset. The time above Hours

Resettable changes to 0.

Transferring Stations to a Standby Pump

If a pump fails, you can transfer all of the controller’s station assignments for that pump to a standby pump. To do this, you must disable (take offline) both the source pump and the standby pump, and the standby pump must have no stations already assigned to it.

The transfer operation at the controller’s touch screen merely changes the pump assignment for every station on the failed pump. It does not transfer any pump settings for auto shutdown delay, alarms, or blow-back to the standby pump. Mechanical connections must be changed manually.

To transfer stations from a pump to a standby pump, complete the following steps:

1. At any screen, touch Menu, and then touch Pumps. The “Pump Status” screen appears.

2. Both the source pump and the standby pump must be offline. If either pump is any other state, disable it by touching its icon briefly. The icon becomes black with a gray outline.

3. Move the vacuum hose from the failed pump to the standby pump, and carry out any other mechanical procedures needed to use the standby pump.

4. At the “Pump Status” screen, touch and hold the icon for any pump until the “Pump

Setup” screen appears.

5. At the “Pump Setup” screen, touch Transfer Stations To Standby Pump. The

“Transfer to Standby Pump” screen opens:

Note:

When you enter the second pump number, the controller checks to make sure that both pumps are offline and that the standby pump has no stations assigned to it.

2–Pump 20-Station Controllers Operation 35 of 51

If these conditions are not all met, error messages appear on the screen instead of a Transfer to Standby Pump button. If you get an error message, first check to make sure that you have entered the correct numbers and reenter if necessary. If another error occurs, see the Standby Pump Errors section below.

10. Touch Transfer To Standby Pump. “Transfer in Progress” appears briefly on the screen, followed by “Transfer Complete,” in place of the Transfer To Standby

Pump button. The controller switches the setting for Source Pump to the new pump and switches the setting for Standby Pump to 0 (unassigned).

To scroll up and down through the list, touch ▲ and ▼ at the bottom of the list.

Silencing Alarms

Whenever a new alarm occurs, your controller sounds the horn and turns on the strobe light at each central alarm.

Touch Alarm Silence on the alarm message banner that appears when a new alarm occurs or press the physical push button included in the central alarm option.

The horns and lights at the central alarms turn off. Your controller has separate, configurable settings for how long the horns should remain silent and how long the lights should remain off. (see “Setting U1p Alarm Duration” on page 19). If the alarm condition still exists when either of these times elapses, the corresponding device (horn or lights) turn on again and the alarm message banner appears with a “Suppression/Silence Time Expired” message. If a new alarm occurs, both horns and lights turn on. See page 436 for a list of alarms and their possible causes.

Chapter 5: Restoring a Lost or Corrupt

Program

PLC Memory Module

A PLC memory module (ACS Part# A0567138) loaded with the appropriate program for the system purchased is provided as both a backup in the event of a catastrophic failure and as a means to upgrade the PLC program.

Depending on the system purchased, the memory module will contain:

1. A0573702 VTC 2/20 AC Inputs

2. A0573712 VTC 2/20 DC Inputs

In the event that the PLC memory becomes corrupted, the memory module can be used to reload the PLC program with factory default values. The red FAULT indicator on the PLC indicates a problem with the PLC memory or an error in the internal settings and may be flashing or on steady. Follow the procedures below to reload the PLC program.

1. Open the front cover of the PLC by pulling on the tab above the words “Allen-

Bradley” to expose the memory module socket. Refer to the diagram, item 7 shown below.

Hopper Loaders with/without Sight Glasses 38

2. Insert the memory module. Note: this step can be preformed while the unit is powered, however care should be taken not to contact any wiring within the control cabinet.

3. Cycle power to the control cabinet allowing approximately 30 seconds for the DC power supply (if provided) to fully discharge.

4. After approximately 30 seconds, the PLC’s green RUN indicator will flash indicating the PLC is reading the memory module. When complete, the PLC will automatically begin operation and the RUN indicator will be on solid.

5. Note that re-loading the memory module will restore ALL settings to their factory default values and the settings will have to be re-entered manually.

Contact ACS service at 1-800-423-3183 if the fault persists.

Chapter 6: Configurable Settings/Defaults

This section describes the proper setup of the 2 pump, 20-station control system parameters.

These parameters are operator changeable; however, these items should require setup only during the initial installation. Only authorized personnel should change them.

Many of the variables and setup parameters have been preset at the factory and do not need to be changed. However, this section of the manual will address all of the setup parameters that were available at the time of printing. The purpose of this is to familiarize the reader with all the setup parameters and their usage.

6-1 Station Setup - Factory Presets

Name Description

Conveying Options

Convey time

Length of time the station’s vacuum valve remains open to allow material to be drawn in. (For a volume-fill station, the valve closes when material covers the station’s volume-fill proximity sensor or this time elapses, whichever comes first.)

(Last convey time)

Dump delay

Assigned to pump n

Special convey

Adjust this value to match the actual time needed to fill the station.

Display only. Length of time the station’s vacuum valve was open for receiving material during the most recent convey. This information is displayed for your reference when adjusting convey time and dump delay.

Length of time allowed for material to drain from the station into the receiver. The controller will not attempt to deliver more material to the station until this time has elapsed.

Adjust this value to match the actual time needed to drain the station. If it is set too short, the controller may attempt to refill the station before it is empty, causing material to back up and/or underusing the station’s capacity. If it is set too long, the system may be unable to keep up with your equipment’s demand for material.

Number (address) of the pump to which this station’s vacuum line is connected.

When this option is enabled, the station’s vacuum valve remains open for the convey time, even if the station is not demanding material and is indicating that it is full. When disabled, the station’s vacuum valve opens when there is demand from the station, and it remains open until the convey time has elapsed or material trips the volume-fill proximity switch.

Enable this option if and only if the station has no flapper.

Alarm Options

No convey

# attempts before alarm

When this option is enabled, the controller issues a “no convey” alarm if it has repeatedly attempted to convey material to the station but the flapper never opened during the dump delay. (The number of attempts is controlled by the next setting.)

Usually this option should be enabled. At times, you may wish to disable it during operation as a stopgap measure for dealing with an alarm.

Number of attempts before alarm: the number of times the controller will attempt to convey material to a station before it issues a “no convey” alarm.

The setting for this option depends on (a) how much material your injection mold uses to make each part compared with the capacity of the receiver and (b) how important it is to keep your injection mold from running out of material and shutting down. A higher setting will give you fewer alarms, at the risk of emptying the receiver without warning. A lower setting will give more frequent alarms, at the risk of disrupting operations unnecessarily. disabled, enabled disabled

6-2 Pump Setup - Factory Presets

Several of the items in this screen are not setup options but are instead intended for use during operation. These items (hour meter and transferring stations to a standby pump) are described in Chapter 4, which cover operation procedures.

Name Description

Idle Time Options

Auto shutdown delay

Length of time the pump continues to run unloaded without demand from any station. After this time has elapsed, the pump shuts down to save power and to prevent wear on the pump.

Adjust this setting to fit the needs of your facility in trading off the savings against the costs associated with waiting for a pump to start up when there is a demand for material.

Alarm Options

Pump fault

The control has one input/pump that you can wire to generate alarms for situations of your choosing. For example, you may have a sensor that turns on when material reaches the top of a filter-chamber waste bin. When this option is enabled, the controller issues an alarm if the sensor wired to the input for Pump

Fault turns on.

Enable this option if and only if your facility has installed a miscellaneous alarm on the input for

Pump Fault for this pump.

Blow Back Options

Blow back

Every n loads

# pulses

On time

Off time

When this option is enabled, the controller periodically sends air backward through the pump’s air filter to dislodge accumulated dust and debris.

Enable this option if and only if the pump has the equipment for filter cleaning.

Number of conveying cycles to stations between filter cleanings.

Adjust this setting based on experience. The more dust and debris in your material line, the smaller this number needs to be.

Number of pulses of air sent through the pump’s filter during cleaning.

If filter-cleaning is not working as desired, the service department may ask you to change this setting.

Number of seconds that the output remains on for each pulse during filter cleaning.

If filter-cleaning is not working as desired, the service department may ask you to change this setting.

Number of seconds between pulses during filter cleaning.

If blow-back is not working as desired, the service department may ask you to change this setting.
