Introduction 1 Introduction Thank you for choosing the MX5-S automated balance or the UMX2-S automated balance from METTLER TOLEDO. These balances enable the weight of cylindrical weighing samples to be determined precisely. They provide the full range of functions of the MX and UMX balance software. This chapter contains basic information about your MX5-S/UMX2-S automated balance. Please read this chapter carefully, even if you already have experience with similar systems. 1.
Unpacking and setting up the balance 2 Unpacking and setting up the balance This chapter provides information about unpacking and setting up your balance. This information is limited to the special features of MX5‑S/UMX2-S automated balances, therefore please note the cross-references to the operating instructions for AX and MX/UMX balances. 2.1 Unpacking the balance Carefully unpack your balance. Note: The packaging of MX5-S/UMX2-S automated balances differs from that of MX/UMX balances. 2.
Unpacking and setting up the balance 2.4 Assembly of the balance and connection to the power supply Use the supplied connection cable to connect together the control unit and the weighing cell. Positioning plate of the weighing cell in the desired location and secure (with screws or by gluing). The foot of the weighing cell should be in the hole (A). A Weighing cell in the positioning plate. Make sure that the front foot of the weighing cell is in the circular hole.
Unpacking and setting up the balance Make sure that the weighing chamber cover (F) is closed, then place the protective cover (G) over the weighing cell. F G Adjust the protective cover vertically: There are 4 screws (H) with lock nuts (I) on the inside of the protective cover. Adjust and secure these screws so that: H – The protective cover is totally horizontal and does not rock.
Unpacking and setting up the balance Insert the electrodes as far as they will go into the fastening strip (D) and tighten the two screws (E). E C D C E Place the protective cover over the weighing cell. Connect the electrodes to the power supply unit and the power supply unit to the power supply (see instructions for the power supply unit). 2.6 Instructions for transporting the balance When transporting your balance, please observe the corresponding instructions in Chapter 2.
Loading mechanism of the weighing cell 3 Loading mechanism of the weighing cell The loading mechanism of the weighing cell for your MX5-S/UMX2-S automated balance has been specially developed for use in automated environments. The loading mechanism is controlled by a host computer using MT-SICS commands and loading is carried out automatically (e.g. using a robot). However, the loading mechanism can also be controlled manually using the «K» door keys on the terminal.
Loading mechanism of the weighing cell 10 3.3 Controlling the loading mechanism using MT-SICS commands The “WS” MT-SICS command can be used to directly control each position of the weighing sample holder. Note: For standard MX/UMX balances the “WS” command is used to control the glass draft shield (see “MT-SICS for AX/MX/UMX balances 11780417” reference manual).
Loading mechanism of the weighing cell 11 Program example: PC / Software UMX/MX Automated User Start test Open comport Send SI (SI) Answer (e.g. "0.00003 g") Flush answer (only for communication check) If communication ready then go forward, else stop program Loop start Send "WS 1" (WS 1) Answer: e.g. WS A Send D "load & print" (D "load & print") Answer: e.g. D A Send K 3 (K 3) Put weight on pan and press print key Answer: e.g.
Create FirstWeight (empty pan) Loading mechanism of the weighing cell Send WS 2 (WS 2) 12 Answer: e.g. WS A Send WS (WS) Answer: e.g. WS A 2 If answer=WS A 2 then go forward, else send WS again Send SU (SU) Answer: e.g. 10.12 mg Create SecondWeight (weight on pan) Create and display results If last probe then go forward, else go back to loop start Send K 3 (K 3) Answer: e.g. K A (K A) Send "WS 1" (WS 1) Answer: e.g.
Send "WS 0" (WS 0) Loading mechanism of the weighing cell 13 Answer: e.g. WS A Send WS (WS) Answer: e.g. WS A 0 If answer=WS 0 then go forward, else send WS again Send D "end & print" (D "end & print") Press print key Answer: e.g. D A Print key Event: e.g. K 7 Send K 1 (K 1) Answer: e.g. K A Send DW (DW) Answer: e.g.
Cleaning and maintenance 14 4 Cleaning and maintenance Your MX2/UMX5 automated balance does not require laborious maintenance. For correct operation and to ensure correct results simply carry out the cleaning and maintenance tasks described below. For information about general cleaning tasks for the balance, please refer to Chapter 13 of the operating instructions for AX and MX/UMX balances. Clean the components of the weighing chamber as follows: Switch off the balance.
