1.0 INTRODUCTION For advice and information about the Welcome to your new LS series advanced, NEXYGENPlus™ data analysis and applications single column, universal testing machine. It software, please contact your authorised LLOYD incorporates an extensive range of features INSTRUMENTS Sales Representative. making it ideal for performing complex testing applications.
These shields have an electronic interlock such that the test cannot be started until the hinged shield is closed. While not mandatory for many applica- tions and countries, AMETEK Lloyd Instruments Ltd. strongly recommends that users consider fitting this option.
3.0 INSTALLATION 3.1 UNPACKING The LS on its own, without the packing and accessories weighs more than 50kg (110lb). Therefore, safe lifting practices should be employed and lifting equipment used as necessary. The LS test machine is packed in a rugged shipping crate to minimize damage caused from shipping mishandling.
3.3 VOLTAGE SELECTION The LS can be used with electricity supplies of either 230Vac ±10% or 115Vac ±10%. The power in- put cable should be inserted at the rear of the machine. Before switching on the machine you MUST check the correct voltage has been selected on the mains input connector. Ensure that the selection is correct for the voltage of your power supply.
Extensometer Interface Connector Load Cell Cable Connector USB Port Hand Held Remote or Main Console Connector Emergency Stop Button Safeline Button When illuminated, the safeline switch is open. There is no crosshead movement or motor control. Depress the button to close the switch and allow for motor and crosshead movement.

NOTE: No specific information about mounting an LS Pogo can be issued with the machine on it’s own because the size and specification of the frame are decided by the customer’s specific needs. The frame should be positioned first and the instructions for set-up and wiring supplied with the frame followed closely.
4.0 LOAD CELLS 4.1 CARE OF LOAD CELLS ALL machine operators should be aware that LLOYD INSTRUMENTS’ Load Cells are precision force measuring instruments, which should be treated with the utmost care to avoid accidental damage. In particular low force Load Cells are easily damaged if abused or used without sufficient care. NOTE: Do not submit Load Cells to physical shock of any kind.
4.3 GENERAL PRECAUTIONS The following points should be considered: When installing the upper grip (particularly heavy ones) on the load cell eye end, avoid bumping the eye end. If the grip is a close fit, DO NOT FORCE IT, establish the reason and rectify. Im- mediately set, or re-set, the bottom limit stop so the grips will not meet when the crosshead is lowered.
5.0 ACCESSORIES 5.1 EXPANDED TABLE An extended base table is available to assist with the testing of wider items. There are 2 versions of the extended table which has 25 tapped holes strategically placed for easy anchoring of the part to be tested using customised jigs and fixtures, additional holes may be added by the user, 1 version has M6 tapped holes the other version has # 10-32 tapped holes LS User Manual...

Twenty-five (25) tapped holes for attaching custom fixtures. LS Extended Work Table There are two (2) versions of the table. The part numbers for each are as follows: M6 Threads SPK/LS/0001 #10 – 32 Threads SPK/LS/0002 LS User Manual...
5.2 DRIP TRAY The optional Drip Tray (SPK/LS/0003) is designed for catching any liquid that may be spilt when car- rying out a test. The drip tray fits around the bottom anchor pin and is clamped in place by the anchor pin, locking nut or the grip threaded adaptor.
6.0 CONTROL CONSOLES 6.1 MAIN CONTROL CONSOLE DESCRIPTION The unit has a Liquid Crystal Display (LCD) to show set-up information, load and extension values etc. and a key pad to input information for operating the machine when under control of the console. The machine is set up by answering simple questions and entering information when requested.
6.2 KEYPAD OPERATION AND Jog Keys DESCRIPTION Fast Jog Zero The keypad has 25 keys arranged into 4 groups. The first group contains 8 keys in the bottom right hand corner of the keypad The First Group of Keys The GO button is used to start a test from the machine console and is operable from the “Pre-Test”...
Page 20
The second group contains 4 keys directly below the display. These “Soft Keys” are used to select various options that are identified by the text displayed on the lower lines of the display as described later. Dynamic Function Keys Mapped to Displayed Information ALPHA-NUMERIC KEYS contains 12 keys on the left hand side of the keypad.
6.3 THE DISPLAY The display, which has 4 lines of 40 characters, is used to show or request information. The informa- tion displayed depends upon the status of the machine but generally, the top line displays a title or help information for each display. The lower lines are split into 4 blocks, one block above each Soft Key, to indicate the function of that key.

All operators must receive adequate training in basic operation before being allowed to use the machine. Additional copies of this manual are available from AMETEK Inc. Operators must ensure that the Emergency Stop Button is never obstructed.
7.2 EMERGENCY STOP If for any reason, the machine needs to be stopped without delay, an emergency stop mushroom switch is provided. Pressing the switch stops the LS machine immediately. It can be released by turning a quarter-a-turn clockwise. The machine will then go to the initialized/start-up sequence if the ON/OFF switch is already ON.
7.4 LOWER ANCHOR PIN ADJUSTMENT The Lower Anchor Pin can be adjusted to align itself with the attached load cell. To align the load cell to the lower anchor pin lower the load cell on to the moving ram so that it is very close to the lower anchor pin using the jog keys.
LIMIT STOPS The LS machines are fitted with two mechanically activated limit stops. These can be used as extra protection to stop load cells, grips or fixtures coming into contact. The upper one can be used to back up the software limit. Activating a limit stop will result in the machine stopping. To adjust the lower limit stop, first loosen the lower limit stop screw and move the stop to the bot- tom of its travel in the slot.

If during a test or when manoeuvring the crosshead, a limit stop switch is activated, a display as shown below or similar will be seen. ERROR condition Lower limit switch press ENTER to cancel When ENTER has been pressed and this display has been cleared the machine will only allow the operator to drive the crosshead away from the limit stop.
