Chapter 1: Theory of Operation Chapter 1: Theory of Operation The Gemco Series 2120 PLC Interface Module converts the input signal from a resolver based rotary transducer or Magnetostrictive Linear Displacement Transducer (LDT) to digital analog or overtravel relay outputs. Resolver based inputs provide up to 14 bit resolution per turn with a field programmable scale factor. LDT based inputs allow field selection of position data in inches to .001 inches or millimeters to .01 millimeter.
Chapter 2: Hardware Overview Chapter 2: Hardware Overview This chapter contains descriptions of the Interface Module’s components. For installation instructions, see Chapter 3: Mounting and Wiring. The Interface Module contains a heavy-duty case which can hold up to five modules. Several optional modules can be used with the Interface Module. See also Appendix C: Catalog Numbering System for more information on optional modules.
Chapter 2: Hardware Overview 2.1: Standard Modules This section provides descriptions of basic Interface Modules (also see Section 2.2: Input/Output Modules). Controller (FMMP01) This module contains the Central Processing Unit (CPU) which is used to process data it receives from the resolver or Linear Displacement Transducer (LDT). It then shows the position on the Interface display. The controller is also responsible for continuously monitoring all programmed setpoints and timing functions.
Chapter 2: Hardware Overview Variable Pulse (FMIP01) Input Option V1 This module is used with an LDT that provides its output in the form of a pulse width modulated RS-422 signal. This module only works with Gemco Series 951VP2110 LDT’s. LDT Input (FMIP02) Input Option L1 This module will accept an output from a controlled pulse, start stop pulse or variable pulse magnetostructive LDT. This card accepts a wide range of LDT inputs and provides faster updates than the variable pulse version described above.
Chapter 2: Hardware Overview Relay Output (FMOR01) This optional module contains two overtravel limit relays. These relays can be programmed to either energize or deenergize upon reaching the programmed overtravel position. These relays will also actuate upon detection of the system and operating errors listed in chart A-5 in Appendix A. 2.3: Status LEDs Defined The Interface Module has 10 status LEDs and four programming keys.
Chapter 2: Hardware Overview POSITION This position LED turns on when the Interface Module is showing position in the large LED display. RPM The RPM LED turns on when the Interface Module is showing RPM in the large LED display. UPR LIM The upper limit LED reflects the state of the relay when the value programmed in the Upper End Limit function is reached. The relay can be programmed to energize or deenergize upon reaching the programmed overtravel position.
Chapter 3: Mounting and Wiring Chapter 3: Mounting and Wiring This chapter provides instructions for mounting and wiring the PLC Interface Module. These instructions have been divided into two sections: Section 3.1: Mounting and Section 3.2: Wiring.
Chapter 3: Mounting and Wiring 5. Insert each #6-32 UNC screw into each of the module’s screw holes. 6. Using a 7/64" Allen wrench, secure the screws into position. This will secure the mounting rails. 8 to 10 inch pounds of torque is required. Cabling The signals from a resolver or LDT are inherently very immune to electrical noise.

(See Figure 3-4). Power input: 85-265 VAC at 450 mA maximum. Fault check output: 8 amps 250 VAC, 30 VDC, 1/4 HP 125, 250 VAC.
Chapter 3: Mounting and Wiring Resolver Module (FMIR01) The resolver module has an eight-position connector. (See Figure 3-5). The terminal wire size for all positions is No. 22-12 AWG. The reset-to-preset input is an edge sensitive input that resets position data to a preprogrammed value. An open collector sinking device or dry contact applied to these terminals activates the input. For programming of reset-to-preset value, see Chapter 4: Programming.
Chapter 3: Mounting and Wiring LDT Input (FMIP02) Input Option L1 This module will accept an output from a controlled pulse, start stop pulse or variable pulse magnetostrictive LDT. (See Figure 3-7). This card accepts a wide range of LDT inputs and provides faster updates than the variable pulse module as described on page 12. The pulse width signal is converted to position data which the monitor displays. The module also provides +24 VDC to supply power to the LDT.

Chapter 4: Programming Chapter 4: Programming This chapter provides detailed descriptions and instructions for programming all Interface Module’s functions. A complete list of functions (with brief explanations) can be found in Appendix B: Function Summary Chart. This chapter divides the functions into the following seven sections. 4.1 Resolver Input Configuration Functions 4.2 LDT Configuration Functions 4.3 Monitor Setup Functions 4.4 Relay Setup Functions 4.5 Digital Outputs 4.6 Analog Outputs 4.
Chapter 4: Programming Figure 4-1 calls out the Interface Module’s programming keys. Following this figure are descriptions of these keys and how they work, as well as, a short tutorial on how to use the keys. Status LEDs PROGRAM FLT OK MVT FLT POSITION RPM UPR LIM LWR LIM AUX 1 AUX 2 AUX 3 SERIES 2120 F( ) Enter Key Shift Key Scroll Key Function Key Figure 4-1 Programming Keys Programming Keys Defined The Interface Module has four keys located on the front panel.
Chapter 4: Programming The shift key is used to move to a specific digit shown on the Interface Module’s LED display. This can be done to either select a function number or a value for a function. To move to a specific digit on the display, select the function key and then the shift key. The right-most digit will then flash. This indicates that the digit is activated to be incremented. (To increment the digit, select the scroll key.) Continue to select the shift key until the desired digit is activated.
Chapter 4: Programming Turns Counting Wrap Around (308) When using the Turns Counting software described above where the Turns Count Function (301) is set for 2 or more, you have the option of selecting the Wrap Around feature. Under normal operation, you select a scale factor using function 300 followed by the number of turns required to reach the selected scale factor using function 301.
Chapter 4: Programming NOTE: The Interface Module is defaulted to stay in program mode for 120 seconds. The monitor will drop out of program mode if a key is not pressed within this time. If this occurs, you will have to repeat steps 1-3. Further, the access code (2100) is provided initially. This code can be changed through the use of the New Access Code function. For security reasons, this function can only be implemented when the monitor is in supervisory mode.
Chapter 4: Programming Program Position Offset (302) (F) 13. Select the function key. The monitor displays “F----”. 302 Enter desired reading 14. Select function number 302 (Position Offset Function). Select the enter key. The monitor displays the current position. 15. Enter the actual or desired machine position reading. Select the enter key. After configuring the encoder module for use with a resolver, you can proceed to Section 4.3: Monitor Setup functions.
Chapter 4: Programming Enter Desired Position 21. Enter desired Reset Value. Select the enter key. NOTE: If 301 is set to 0, the Reset Value must be less than the Scale Factor. 4.2: LDT Configuration Functions There are two input cards available for use with LDTs. 1. Specified as option V1 in the part number and is labeled (FMIP01) on the card. 2. Specified as option L1 in the part number and is labeled (FMIP02) on the card.
Chapter 4: Programming Wire Speed (300) Programming of the wire speed synchronizes the performance of the module with the performance of the LDT. You will find the wire speed on the legend plate of your LDT. To program wire speed, perform the following steps: (F) 1. The monitor displays “F-----”. 300 2. Enter new value Select the function key. Select function number 300. Select the enter key. The monitor displays the current wire speed. 3. Enter the new wire speed value.
Chapter 4: Programming Count Direction Function = 0 Count Direction Function = 1 100 0 When the Count Direction Function is programmed with a value of 0, the display value will increase when the LDT’s magnet assembly is moving away from the head of the LDT. 100 When the Count Direction Function is programmed with a value of 1, the display value will increase when the LDT’s magnet assembly is moving toward the head of the LDT.
Chapter 4: Programming Fault Pulse Time (306) Most magnetostrictive LDTs send out a fault pulse during a fault condition. The series 2120 Interface Module is preset for use with all Gemco LDT products. The Fault Pulse Time function is used to program the pulse time of the fault signal sent by an LDT not manufactured by Gemco. When the monitor receives a fault signal of this pulse time, it will indicate an error (see Appendix A: Error Messages). The default for this function is 10 microseconds.
Chapter 4: Programming After configuring the Interface Module for use with an LDT, you can proceed to Section 4.3: Monitor Setup Functions. LDT L1 Input Reset-to-Preset (311) The reset-to-preset input is an edge sensitive input that resets position data to a preprogrammed value. A 5-24VDC source applied to these terminals activates the input. (F) 1. The monitor displays “F----”. 311 2. Enter desired value Select the function key.
Chapter 4: Programming (F) 1. The monitor displays “F-----” 14 2. Enter function number 14. Select the enter key. The monitor displays the function’s current value. Enter either 0 or 1 Select the function key. 3. Enter either 0 or 1. Select enter key. NOTE: If you change the unit of measurement, the decimal location shown on the monitor’s LED display will change to the default position for the unit of measurement selected.
Chapter 4: Programming used for the Position Hold dwell time. The position hold dwell time is the amount of time the monitor continues to hold the displayed position after the auxiliary input is released (or activated, depending on the input’s programmed state). To enable or disable the Position Hold function, perform the following steps: (F) 1. The monitor displays “F-----” 15 2. Enter either 0, 1, or 2 Select the function key. Enter function number 15. Select the enter key.
Chapter 4: Programming (F) 16 Enter either 0 or 1 The monitor displays “F-----” 2. Select function number 16. Select the enter key. The monitor displays the function’s current value. 3. Enter either 0 or 1. Select the enter key. Move Detection Time-out (12) The Move Detection feature is used to monitor the time between when a signal is sent to initiate machine movement and when movement is actually detected. The default value for this function is 5.00 seconds. This value can range from 0 to 99.
Chapter 4: Programming To put the monitor in program mode, see Program Mode Access in Section 4.7: Program and Supervisory Mode Functions. The following is a list of the press setup functions: Upper End Limit (400) Lower End Limit (401) Relay State (402) Relay Override (403) Upper End Limit (400) The Upper End Limit function is used to program the position value at which the upper end limit relay actuates.
Chapter 4: Programming Enter lower end limit The monitor displays the function’s current value. 3. Enter the new value. Select the enter key. NOTE: To temporarily override the lower end limit relay, see Relay Override. Relay State (402) The Relay State function is used to program the Interface Module’s upper and lower limit relays to either energize or de-energize when their programmed value is reached or exceed. Either a 0 or 1 can be programmed in this function.
Chapter 4: Programming NOTE: After overriding either the upper or lower limit relays, the operator should move the machine back into its normal operating range between its upper and lower limits. If the machine is again moved in the wrong direction (towards the limits), the upper or lower limit relays will again actuate. Step 1 - 3 will have to then be repeated. 4.
Chapter 4: Programming 201 2. Enter either 0 or 1 Enter function 201. Select the enter key. The monitor displays the function’s current value. 3. Enter either 0 or 1. 0 = Latch (default) 1 = Synchronize Select the enter key. Logic Level (202) This function will set up selection of either high true or low true logic. (F) 1. Select the function key. The monitor displays “F-----” 202 Enter either 0 or 1 2. Enter function 202. Select the enter key.
Chapter 4: Programming 4.6: Analog Outputs The Analog Output board provides two channels of analog output that can be independently configured and scaled. Each channel can be configured for an output based upon position or velocity. Velocity will be RPM if the sensor is a resolver or inches/mm per second if the input sensor is an LDT. The two channels of analog output allows you to configure one analog output to be based on position while the other channel provides a simultaneous indication of velocity.
Chapter 4: Programming (F) B) Select voltage or current output 1. Select the function key. The monitor displays “F-----” X04 2. Enter function number X04. Select the enter key. The monitor displays the current function value. Enter 0 or 1 0 = voltage output 1 = current output 3. Leave current value or change. Select enter key.

The monitor displays current voltage output value linked to minimum RPM value. 8. Enter 2. Select enter key.
Chapter 4: Programming Analog output channel 1 will now provide a 2 to 8 VDC output as RPM increases between 500 and 2000 RPM. RPM values below 500 RPM will result in a 2 VDC analog output. RPM values above 2000 RPM will result in an 8 VDC output. Analog output channel 2 is programmed using the same basic sequences except with the function numbers noted below. Remember that the X shown in the function number represents the slot in which the analog output board is installed in the Interface Module chassis.
Chapter 4: Programming 4.7: Program and Supervisory Mode Functions This section provides descriptions and instructions for program and supervisory mode functions. These functions are used to put the Interface Module in either program or supervisory mode, as well as, program the length of programming time and change the program mode access code. Before a function can be programmed, the monitor must be in program mode.
Chapter 4: Programming NOTE: If the Interface Module displays only one zero (i.e. “0”), then the program lockout connector is not jumpered. For wiring instructions, see Section 3.2: Wiring. Enter access code 3. Enter either the program or supervisory mode access code. The default program mode access code is 2100. Select the enter key. The monitor is now in either program mode or supervisory mode. The program mode LED is turned on.
