15 4 DESCRIPTION AND SPECIFICATION Overview of Use Capabilities Safety Due to variances in tank design, the values are approximate. The Automatic Fill Controller (AFC) provides intelligent control and monitoring of fuel delivery and storage. The AFC allows for remote filling of one to two tanks while monitoring their fuel level. After an established limit is reached, the filling is stopped, and the operator is alerted. The AFC allows for multi-tank filling and monitoring, and through sensors in the tanks, displays the fuel level in real time. The AFC can control up to sixteen tanks. A touch screen provides control and monitoring, while communication options allow for central monitoring from a building management system (BMS/BAS). The Automatic Fill Controller provides solutions to common fueling problems while allowing for future expansion. The use of a single Main Automatic Fill Controller (AFC) provides monitoring and control for Tanks 1-4. With the addition of an Automatic Fill Controller Slave (AFC-S), Tanks 5-8 can be monitored and controlled. By adding a second or third Automatic Fill Controller Slave, Tanks 9-12 and Tanks can be supported. The AFC is capable of monitoring and controlling round or rectangular tanks up to 100,000 gallons. The AFC controls a single Motorized Ball Valve per tank and also monitors the position of each valve to ensure accurate filling of the desired tank. If the position of any tank s valve is not verified, further operation is prohibited for the entire system. This verification prevents the wrong tank from being filled. The AFC monitors the fuel level in each tank and displays the levels in gallons or percentage. The AFC is also equipped with a display of the total fuel in all tanks. Each tank within the AFC can be programmed independently for shape, volume, and height as well as low level alarm (%) and refill (%) alert. The default value for the full level is approximately 90%. The default value for the high level is approximately 95%, and the default critical high level approximately 98%. The AFC can also alert the user when the tank reaches adjustable refill and low fuel levels. The AFC also monitors a leak sensor for each tank. When a Description and Specification 9

16 leak is detected, filling of that tank is prohibited. An auxiliary leak sensor is also available. The motorized ball valves are fitted with manual overrides to allow filling in emergency situations. Table 1 Specifications Input Voltage 120VAC, 1-phase Frequency 60Hz Full Load Amps 5A Enclosure type 3R Short Circuit Current Rating 120Vac Communications Modbus RTU RS-485 (Optional Modbus TCP/ IP available) Tanks Supported Up to 16 via slave panels (1-4 with main controller, each slave panel adds an additional 4 tanks) 10 Description and Specification

17 5 INSTALLATION The Automatic Fill Controller should be mounted at the filling station, then wired to the power source, float assemblies, valves, and any other sensors or system integration connections. Slave panels can be mounted near the additional tanks to allow for efficient wiring installations. Once mounted and properly wired, the AFC-S panels must be set up, and the main AFC panel must be programmed. There are three mounting options for the AFC panels: 1. Fuel Port/Smart Pump side mount 2. Wall mount 3. Flush Wall mount. These options must be specified when ordering to ensure the proper brackets are included with the controller. Installation 11

18 Installing Wiring If there are any questions about wiring the AFC panels, please contact Simplex Inc. Simplex Inc. is not responsible for damage due to incorrect wiring installation. Each AFC panel must be completely wired prior to applying power. Failure to follow the wiring information and guide may result in product damage and loss of warranty coverage. If requested, startup services can be provided by Simplex Onsite, Inc. or Simplex, Inc. to check field wiring prior to applying power as well as assuring proper operation.

26 Did you know? Michael Debrey got the idea for the Automatic Voltage Regulator while working as an electrician at a furniture factory on the night shift. Part of his job was to regulate the output voltage of a steam turbine generator by hand. Being a skilled tinkerer, he developed a device to do it for him.

27 Installing Dry Contact Alarms To connect the controller to external alarms, connect TB- R-1-4 to your system. These four terminal blocks provide for four configurable alarms to be integrated into your facility s system. In each terminal block, continuity between the.1 and.3 connections indicates normal operating status, and continuity between the.1 and.2 connections indicates an alarm. See Figure 18 on page 21 for an explanation of connection designations. Figure 18 Terminal Block Levels Installation 21

28 Installing Slave Panels To install slave panels, mount the panels where desired and install power cables, float assemblies, and valves in the same fashion as the master controller. See page 15 through page 17 for more information. Configure the switches on the PLC as detailed in Panel Setup on page 23. The slave panels connect to the master panel in a daisy chain fashion. It does not matter in what order the panels are connected. All further setup will be done through the master panel. 22 Installation

29 6 SETUP Panel Setup While the Automatic Fill Controller comes from the factory set as the master controller, the panels used as the Automatic Fill Controller Slave panels have to be set according to the tanks they are controlling. During installation, prior to applying power to the panels, open the outer doors of the AFC-S panels, and locate the PLC in the upper right corner (Figure 19). On the right-hand side of the PLC, there is a set of switches (Figure 20). Set the first three switches as detailed in Table 2. Figure 19 PLC Figure 20 Switches Table 2 AFC DIP Switch Settings Main Slave Slave Slave Tanks 1-4 Tanks 5-8 Tanks 9-12 Tanks Switch 0 Off On Off On Switch 1 Off Off On On Switch 2 Off Off Off Off Setup 23

30 Controller Setup Clock setup After the AFC panels have all been wired completely, all connections confirmed, and all switches are set appropriately, apply power to the panels. The touch screen will show a Loading... indicator, and then, the main screen will become active (Figure 21). Your unit s clock may need to be set to your time zone. To do so, on the powered touch screen, press and hold on the top left corner for a couple of seconds. After a time, the edit menu will load. You will see a selection to edit the clock. Select this setting, and adjust the time accordingly. This time will be used for your alarm logs. Figure 21 Home Screen Figure 22 Setup Button The touch screen must communicate with the PLC, so you might experience a couple of seconds delay at times. Security Code Select the Setup button on the lower right hand side of the screen (Figure 22). After selecting the Setup button, you will be prompted to enter a security code, which is , the last seven digits of the main phone number to Simplex, Inc. (Figure 23). After entering the code, select the Enter button to be taken to the Setup screen. Figure 23 Input Pad 24 Setup

31 Tank Setup Press the Tank Setup button (Figure 24) and choose which tank to activate and setup (Figure 25). To make a tank active on the tank setup page, you must first select Round or Square, and it will become highlighted in green. By default, the type of the tank is set to Disabled (Figure 26). To set tank height, select the 0.0 under the Tank Height indicator and enter the height of the selected tank. Press Enter (Figure 26). To set tank volume, press the 0 gal button under the Volume indicator, and enter the volume of the selected tank in gallons. Press Enter. To set up a low level alert/warning, select the Disabled button under the Low Level Alarm indicator, and enter the desired level in percentage. Press Enter. If a refill level alert is desired, follow the same procedure as the Low Level Alarm. When you are finished, press the SAVE button (Figure 27). Figure 24 Tank Setup Figure 25 Tank Selection Figure 26 Tank Details Figure 27 Tank Details Setup 25

32 Level Transducer Setup The level transducer must be set to operate for the tank dimensions. To set these dimensions, you must be within the tank setup screen. Press the XMTR 20mA indicator field (Figure 29). You will be prompted to enter a value. If you are using a 7.5 PSI transducer, you must enter 255. If you are using a 1 PSI transducer, you must enter 34. If using a Mag- Probe, you will enter the Mag-Probe height in inches. Figure 28 4 Tanks Figure 29 Transducer Once the tank shape, height, and volume have been set, the level transducer for that tank must be calibrated (zeroed). Figure 30 Zero Transmitter In order to accomplish this calibration, the probe must be removed from the tank or at least above fluid level. While doing so, press and hold the Zero Transmitter button held for several seconds. Repeat this process several times to ensure proper calibration (Figure 30), then secure the probe in the tank. When completed, press the Back button, and repeat the process for any remaining tanks. 26 Setup

33 Did you know? Simplex founder Michael Debrey got his first experience with power generation when he worked as an electrician for the Ringling Bros. Circus.

34 Communication Setup To set up communications with a Building Management System (BMS) or a Building Automation System (BAS), go back in to the Setup screen as described in Tank Setup on page 25. Figure 31 Communication Setup To begin, press the Communication Setup button, which will bring up the screen pictured in Figure 31. To set the slave address of the AFC, select the number below the Address indicator and enter appropriate address in the keyboard prompt. To set the baud rate, press the number below the Baud Rate indicator, and it will cycle through the various values. The included values are 300, 600, 1200, 2400, 4800, 9600, 19200, and To set the parity, press Parity until the appropriate selection is shown. The included options are Even, Odd, and None. In order to properly map the data received by the BMS, have the system administrator refer to Appendix B Modbus Controls on page 55. All points should be verified once set up to ensure proper operation. 28 Setup

35 Dry Contact Setup This screen only determines what alarms will trigger the dry contact circuits. They do not affect which alarms the system will register. To set up alarms for the four dry contacts, enter the System Setup Screen. The top two rows of this screen allow you to configure four alarms (Figure 32). Each alarm has two fields to configure, arranged vertically. The first option, labeled AX1 Tank, determines whether the alarm will be triggered by a specific alarm on any tank in the system (Summary), a selected alarm on the active tank (Selected), or a specific alarm on a selected tank (Specific). To select Selected or Specific triggers, press Setup Alarms to access Dry Contact Setup Screen 2 (Figure 33). Figure 32 Dry Contact Alarms Figure 33 Dry Contact Alarms Here you can select from eight alarms for each Dry Contact and their corresponding tank, if desired: 1. Critical High 2. High 3. Full 4. Refill 5. Low 6. Valve Fail 7. Leak 8. Critical Summary, which combines Critical High, High, Valve Fail, and Leak. When the first alarm has been configured, repeat the process for the remaining three alarms. Setup 29

36 Valve Setup Auxiliary Alarm The AFC will trigger Figure 34 Valve Fail Delay an alarm if a valve does not arrive at the desired state within the Valve Fail Delay. Because there is a variety of valve sizes available, you must specify the delay. This delay dictates how long after triggering a state in the valve, either open or closed, the controller will wait before activating a Valve Fail alarm. For more information about this and other alarms, see Alarms and Warnings on page 39. To set the Valve Fail Delay, go back to the Setup screen as described in Tank Setup on page 25. From the Setup screen, select System Setup. (Figure 34). Most valves supplied by Simplex have a cycle time of about 11 seconds, so we suggest a 30 second Valve Fail Delay. However, if you have installed your own valve, set the delay to be two to three times the valve s cycle time. Also on the System Setup Screen is the option to configure an Auxiliary alarm (see Installing Auxiliary Leak Sensors on page 19). This alarm is triggered by the sensor or switch installed on TB-R (See Figure 35.) This alarm can be configured in three ways: Figure 35 AUX2 Mode 1. N.O. Alarm, which will trip when a normally open circuit closes. 2. N.C. Alarm, which will trip when a normally closed circuit opens. 3. Loss of Flow Select the setting appropriate for the switch or sensor you have installed. 30 Setup

37 7 OPERATING INSTRUCTIONS Before operating the Automatic Fill Controller, the fuel delivery technician must follow the instructions for the fuel port or the smart pump in their respective manuals. These steps include connecting the ground cable, opening the valves for the Fuel Port or Smart Pump, and filling the desired tank(s) using the Automatic Fill Controller. This section will be a guide for operating the Automatic Fill Controller. It should be followed closely in order to prevent improper use. Waking the AFC System Check When idle for a couple of seconds, the touch screen will go to sleep. To wake the AFC from sleep mode, ensure the toggle switch below the touch screen is in the On position, and then, touch the screen to activate it. Before filling the Figure 36 Alarm History tank, check to see if any alarms (displayed in red) or warnings (displayed in yellow) have been registered. Alarms are indicated with red labels while warnings are indicated with yellow labels. Each active alarm or warning will appear one by one at the bottom of the screen no matter which screen is active. To view all of the alarms and warnings in list form, press the Alarm History button, which is found on the tank display screen (Figure 28 on page 26). From this screen (Figure 36), you can delete the inactive alarms one by one or clear them all by pressing the appropriate button. If an alarm or warning is still active, it will not clear. Press the Exit button to return to the main screen. All alarms are also indicated via an audible horn and light on the panel below the touch screen. To silence the horn, push the Silence Horn button below the touch screen. If there are any active alarms, contact the site supervisor immediately. It is safe but not advised to fill when there are active warnings. Operating Instructions 31

43 Order of Operations To fill a tank in the system, you must first select the appropriate tank. To do this, press the level indicator for the desired tank (Figure 39). If the tank you want to select is between 9 and 16 rather than between 1 and 8, press the Tanks 9-16 button (Figure 40). This button only appears if any tanks from 9-16 are activated. This action will take you to the individual tank screen (Figure 41). On this screen, you will see options for opening and closing valves, selecting the previous or next tank, viewing alarm history, or going back to the main screen. When arriving at the selected tank information screen, you will see that the valve position is Closed (Figure 42). To fill the tank, press the Open Valve button, and the valve indicator will show In Travel (Figure 43). When the valve has finished traveling, it will indicate Opened (Figure 44). At this point, you may begin filling the tank. When the tank reaches approximately 90%, the Full indicator will pop up (Figure 45).

44 When the tank reaches the full level, the corresponding valve will close. If you want to add more fuel to the tank, you can press the Open Valve button, and the valve will open for 30 seconds to allow topping off and emptying of hoses. Once the tank reaches approximately 95%, the High Fuel indicator will light up, and the valve can no longer be opened (Figure 46). If after filling, the level is below the Full mark, remember to close the valve before leaving. Repeat this process for all tanks until filling is completed. When done, close the manual ball valve in the Fuel Port or Smart Pump, remove the hose and couplers, and replace the fill cap. Close and lock all doors and cabinets. Remove grounding cable. Turn off the toggle switch on the AFC. Figure 43 Valve In Travel Figure 44 Valve Opened Figure 45 Full Warning Figure 46 High Fuel Warning 38 Operating Instructions

45 8 ALARMS AND WARNINGS Alarms The Automatic Fill Controller is designed to alert users to issues within the filling and storage system. These issues are broken down in to two categories: Alarms and Warnings. Alarms are serious issues that require immediate response, while warnings signal less critical issues. The AFC has several states which cause alarms. Active alarms are indicated by a red light on the main panel below the touch screen, an audible horn, and red indicators on the touch screen (see Figure 47, Figure 48, and Figure 49.) The horn may be silenced by pressing the Silence Horn button right above the horn. All alarms are logged in the Alarm History, which is accessed by pressing the Alarm History button, as well as cycling along the bottom of the screen until cleared from the log. Figure 47 All Alarms On Figure 48 Every Tank Critical Figure 49 Communication Loss Alarms If there is a power loss to the system, the motorized ball valves are fitted with manual overrides to allow filling in emergency situations.

46 Alarm Table 3 shows the states causing alarms and what actions are performed by the AFC. Table 3 Common Alarms Triggered By Actions Taken by AFC Low Fuel Level Level Transducer Audio Visual Alarm only High Fuel Level Level Transducer Prevents the valve for that tank from opening. Critical High Fuel Level Critical High Float or Level Transducer Closes all valves, and prevents any valves from opening. Valve Failure Loss of Signal from MBV or incorrect position indication or timeout Prevents any other valves from opening.* Communication Failure Loss of communication between master and slave panels Prevents any valves from opening. Tank Leak/Aux. Leak/Sump Leak Leak Float Prevents valve for that tank from opening *Requires controller to be reset to be cleared. To do so, power down the controller, then turn it back on. In the event of an alarm or a warning, the motorized ball valves are fitted with manual overrides to allow filling in emergency situations. If there is a critical high alarm, the only way to remove this state is by removing fuel, either through use or return pumps. 40 Alarms and Warnings

47 Warnings The AFC presents warnings for situations that are noteworthy but not necessarily in need of immediate attention. Active warnings are displayed only on the touch screen by yellow indicators (see Figure 50 and Figure 51.) They are also logged in the Alarm History log and are displayed along the bottom of the screen until cleared from the log. Table 4 shows the states causing warnings and what actions are taken by the AFC.

48 Did you know? One of Simplex s first products the Automatic Voltage Regulator could fit in the palm of your hand. Today, we make dozens of fuel systems and load banks, some of which are so large they must be mounted on trailers.

49 9 MAINTENANCE/TROUBLESHOOTING Preventative Maintenance Trouble shooting Remove all power before servicing the fill controller. Never operate or service a fill controller that is not grounded. The AFC is designed to require minimal maintenance. On a yearly schedule, the unit should be fully opened and cleaned out. At this time, it would be a good idea to disconnect power and tighten all connections to ensure proper operation. Depending on how the unit is mounted, this would be a good time to tighten any mounting hardware. To troubleshoot the AFC, a full set of drawings is required. Any electrical work should be performed by trained personnel. Simplex, Inc. is not liable for any damage or bodily harm. If additional help is required, contact Simplex or your local Simplex Onsite Branch for troubleshooting and onsite assistance. If there is a chance of power loss, add Panasonic CR2354 3V batteries (included with the AFC) to the PLC in order to retain the internal memory. Without batteries, the PLC will only retain its memory for a minimum of 4 days and a maximum of 3 weeks. To Install or Replace the PLC Battery: 1. Press the retaining clip on the battery door down and open the battery door. 2. Place the battery into the coin type slot with the +, or larger, side out. 3. Close the battery door making sure that it locks securely in place. 4. Make a note of the date the battery was installed. The following table (Table 5) contains some common scenarios which you may face while operating the automatic fill controller. Maintenance/Troubleshooting 43

57 10 SUPPLEMENTAL EQUIPMENT The Automatic Fill Controller is designed to interface with several other pieces of hardware. Without this additional hardware, the AFC will not function properly. Consult your sales representative to order equipment. Valves Valves, which are required for each tank in the system, can be either motorized ball valves or actuated butterfly valves.

58 Level Transmitters Level transducers are used to determine the fluid level in the tanks. Any 4-20mA sensor can be used as long as it is properly calibrated to the particular tank in which it is used. Due to the variation in tank sizes, particularly height, it is important to select the appropriate sensor. Consult your sales representative for transducer selection.

60 Did you know? Load banks simulate the real world loads that the power source will experience. Electrical load can be broadly classified as resistive, inductive and capacitive. In the real world, these components are mixed, as they are with a load bank, except with the load bank, full control of the components is possible. The most common load bank and the load bank which is suitable for general load testing is the resistive load bank. A resistive load bank converts electrical energy to heat. Within the load bank, the load is divided into discrete circuits or steps capable of stepwise, controlled application. Most load banks are cooled by forced air, but water can be used when silent operation is required.
