15 INST ALLA TION SAFETY PRECAUTIONS W ARNING Installation and service instructions are for use by quali fi ed personnel only . T o avoid injury and electric shock, do not perform any servicing other than that contained in this manual. ST ORAGE INFORMA TION The drive should be stored in its shipping carton in a clean, dry area.
16 INST ALLA TION INST ALLA TION—MECHANICAL Beck Group 1 1 drives may be installed in any convenient orientation, because the gearing does not require an oil bath. Refer to the outline dimension drawings on pages 8–14 for physical dimensions and required clearances.
17 INST ALLA TION SIGNAL WIRING Each Beck drive is custom built to match the control requirements of your system speci fi ed at the time of order . Each drive has a speci fi c wiring diagram attached to the inside of the wiring terminal cover . T ypical wiring connections are described below .
18 INST ALLA TION ST AR T -UP LINKAGE REQUIREMENTS (If Applicable) In most applications, the best control will result when the linkage is adjusted so that the full 100° angular travel of the Beck drive output shaft is used, even though the valve or damper may travel less than 100°.
19 ST ART -UP INSTRUCTIONS After the drive is mounted and its wiring connections are made, it is ready to be tested for proper operation. NOTE: All Beck drives are shipped from the factory ready for installation; no electrical adjustments are required before placing them in operation.
20 OPERA TION HOUSING Beck electronic control drives have individual cast aluminum compartments for each of the fi ve main components: The control motor , wiring terminal block, drive train, digital control module, and control end. Gasketed covers and sealed shafts make the drives ideally suited to outdoor and high humidity environments.
21 LOSS OF DEMAND INPUT SIGNAL (L.O.S.) When the Demand input signal drops to approximately –5%, the DCM-2 considers the Demand input signal to be invalid.
22 INPUT : DIGIT AL CONTROL MODULE (DCM-2) Beck modulating drives are equipped with a precision, digital control module (DCM-2) designed to receive conventional 4–20 mA or 1–5 V dc control signals directly—eliminating the need for contact protection devices, relays, switches and reversing starters.
23 DCM-2 L OCAL INTERF ACE Operation OVERVIEW The DCM-2 customer interface panel (pictured below) allows the user to easily calibrate the drive and troubleshoot conditions. The following information provides an overview of the DCM-2 customer interface panel features.
24 Pushbutton Controls The fi ve pushbuttons (pictured below) on the DCM-2 customer interface panel are used for calibration. When pressing a pushbutton, pressure should be maintained until the “ACKNOWLEDGE” LED lights; this con fi rms receipt of the pushbutton command.
25 All Beck drives are shipped completely calibrated to the customer ’s speci fi cations that were written into the equipment order and are ready to be installed. If the need arises to change the drive calibration, fi rst con fi rm that the drive is installed as speci fi ed and operating properly before proceeding with the change.
26 NOTE: Y our Beck drive was shipped from the factory ready for installation; no electrical adjustments are required before placing it in operation. Each drive is set up and calibrated to the speci fi cations that were written into the equipment order .
27 1. Remove the control end cover and terminal block cover (1/2" bolt heads). 2. Use the electric Handswitch to drive the control shaft so that the CW switch cam screw is accessible. Using a 7/64" hex wrench, loosen the screw so that the cam is just snug on the shaft (see illustration below).
28 DEMAND CALIBRA TION DCM-2 boards are designed to accept a 4–20 mA (or 1–5 V dc) analog demand signal. Narrower spans within this range can also be accommodated for split range operation (see page 29). The input comes calibrated from the factory for the full range unless otherwise speci fi ed by the customer .
29 Split Range Operation It is sometimes desirable or necessary to have more than one fi nal control element controlling a single process. Often, this type of control strategy requires that two to four Beck drives each respond to different portions of one 4–20 mA Demand signal from the control system.
30 POSITION CALIBRA TION In order to correctly position the drive output shaft in response to the Demand input signal, the DCM-2 receives a position signal from the drive’s position sensor and compares this actual position to the Demand input.
31 DIRECTION OF OUTPUT SHAFT ROT A TION (CW vs. CCW) Direction of output shaft rotation is determined by observing the end of the output shaft (see illustrations below). Direction of rotation is de fi ned as the direction of output shaft rotation produced by an increasing Demand signal.
32 START Is there a jumper from terminal A to terminal C? Does drive work with Handswitch? Does drive work properly CW? Does drive work properly CCW? Does output shaft move with Hand- switch in “STO.
33 Does Handwheel shudder about one position? Is the “TEMP °F” LED lit? Is the “STALL” LED lit? Is the “TEMP °F” LED still lit? Is binding or an obstruction present? Clear obstruction Move Handswitch to CW/CCW per direction drive does not move Check SLM for damage; rebuild or replace as necessary.

36 The DCM-2 board is the control center of the drive. Drive configuration and calibration are accessed and set through the DCM-2 board. Using the HART interface requires a HART ® compatible communicator .
37 MENU DESCRIPTIONS (See Figure 1, Page 34) Online Menu (Block 1) When communications are established with the communicator , the Online menu is displayed. This is the gateway to all the other menus and it also provides current information about the drive.
38 DCM-2 HART INTERF A CE Communication Con fi guration Menu (Block 3C) The Configuration menu serves as the gateway to all of the drive operating setup parameters. The user can select any of five different setup submenus that can be used to configure the drive based on the physical layout and the desired operation.
39 Demand Setup Submenu (Block 4D) This menu is where all the Demand input signal related drive parameters are set. The eight parameter entries are as follows: 1. DemRngLwr - The value of the Demand signal (in mA) that corresponds to 0%. Normally set to "4.
40 Statistics Menu (Block 3D) This menu is where all the drive’s stored operating statistics are available. There are eight different statistics available: 1.
41 Diagnostics Menu (Block 3F) This menu provides access to all the DCM-2 stored online diagnostic information about drive operation. The menu provides six submenus accessing drive statistics and online drive status.
42 DCM-2 HART INTERF A CE Communication 3. Identify Device - This command will cause the Acknowledge LED to blink for two seconds. Used to verify proper HART communications as well as an aid in identifying which drive is being addressed when con fi guring multiple drives for split range operation.
43 RealTimeClock Submenu (Block 4M) This menu allows the date and time to be set. The settings are as follows: 1. RTC Day - Numerical entry sets the day of the month. 2. RTC Month - Numerical entry sets the month. 3. RTC Y ear - Numerical (4 digit) entry sets the year .
44 DCM-2 HART INTERF A CE Con fi guration and Setup All drives are shipped completely con fi gured to the customer ’s speci fi cations and are ready to be installed.
45 W ARNING Carefully follow the on-screen warnings and messages when proceeding, because changing drive setup parameters can cause the drive to reposition.
46 DCM-2 HART INTERF A CE Con fi guration and Setup 0% and an over-travel limit switch is open. This eliminates the nuisance message, but does not eliminate the message for other scenarios like the Handswitch being in the STOP position.
47 Changing Characterization STEP 1 - From the HAR T ® communicator “Online” menu, move to the “Demand Setup” menu and select the “Dem Curve” parameter . This is accomplished by using the up and down arrow keys to select the appropriate item in each menu and then moving forward by pressing the right arrow key .
48 DCM-2 HART INTERF A CE Con fi guration and Setup W ARNING Carefully follow the on-screen warnings and messages when proceeding, because changing this parameter online could cause the drive to reposition. This can adversely affect the process and cause potentially dangerous conditions.
49 Enabling T orque Functions STEP 1 - From the HAR T ® communicator “Online” menu, move to the “T orque Setup” menu and select the “T rq/Thrust” parameter . This is accomplished by using the up and down arrow keys to select the appropriate item in each menu and then moving forward by pressing the right arrow key .
50 DCM-2 HART INTERF A CE Calibration All Beck drives are shipped completely calibrated to the customer speci fi cations, and are ready to be installed. If the need arises to change the drive calibration, confirm that the drive is installed as specified and operating properly before proceeding with the change.
51 DIRECTION OF SHAFT ROT A TION (CW VERSUS CCW) Direction of shaft rotation is determined when looking at the end of the output shaft (see fi gures below). Direction of rotation is de fi ned as the direction of output shaft rotation produced by an increasing demand signal.
52 NOTE: Y our Beck drive was shipped from the factory ready for installation; no electrical adjustments are required before placing it in operation. Each drive is set up and calibrated to the speci fi cations that were written into the equipment order .
53 1. Remove the control end cover and terminal block cover (1/2" bolt heads). 2. Use the electric Handswitch to drive the control shaft so that the CW switch cam screw is accessible. Using a 7/64" hex wrench, loosen the screw so that the cam is just snug on the shaft (see illustration below).
54 POSITION SENSOR SETUP In order to correctly position the drive output shaft in response to the input Demand signal, the DCM-2 board receives a position signal from the drive’s position sensor (CPS) and compares this actual position to the desired Demand input.
55 Short-stroke Operation (Reducing Full T ravel) T ypically , it is best to use the full 100% travel of the drive in response to the 0–100% Demand input signal. In certain applications, as a last resort, it may become necessary to reduce the full travel of the drive.
56 DCM-2 HART INTERF A CE Calibration - Feedback FEEDBACK SIGNAL CALIBRA TION DCM-2 boards have the capability of providing a 4–20 mA output signal so that the drive’ s true output shaft travel can be monitored remotely . The signal comes calibrated from the factory to provide a precise 4–20 mA signal corresponding to 0–100% drive travel.
57 DEMAND SIGNAL CALIBRA TION DCM-2 boards are designed to accept a 4–20 mA (or 1–5 V dc) analog Demand signal. Narrower spans within this range can also be accommodated for split range operation (see explanation following). The input comes calibrated from the factory for the full range unless otherwise speci fi ed.
58 DCM-2 HART INTERF A CE Calibration - T orque Measurement TORQUE MEASUREMENT CALIBRA TION DCM-2 boards have the capability of measuring the drive output torque and providing several torque-related features. The torque measurement is calibrated to the drive’s rated output at the factory .
