1 Introduction

1.1 Introduction The Digital Interface/Lineariser Module is a plug-in module, designed to be fitted into the front of a Model 410 Flame Photometer. The module consists of an analogue to digital converter and RS232 serial output socket. Any printer with the ability to accept data at 9600 baud or computer may be connected. This facility is available to all existing users as the module fits directly to the front of the Model 410 underneath the logo plate. The module presents two buttons. One enables the user to toggle between Blank, Calibrate, Sample and Repeat to select the current operation description to be printed alongside the value displayed; the other is the print command which prints the displayed value with the time, date and sequence number. If your instrument already has a lineariser fitted, this module physically replaces it (its circuitry also incorporates the linearisation algorithm). This will correct for Sodium values only up to 20ppm. If linearisation is not required, the function can be disabled before fitting the module to the instrument.



2 Installation

2.1 Unpacking 1. Unpack the module and accessories.

2. Check all items for damage.

3. Check that all the items on the Accessory List have been delivered. Contact your Sherwood Scientific distributor if you have any problems.

4. The Module is shipped with the following items:

Accessory List CAT. NO. ITEM QUANTITY

410 86 001 Module 1 410 09 003 Lead, M410 to Printer/Computer 1 410 91 006 Installation/Operator Manual 1



2.2 Assembly To assemble the module to the Model 410, proceed as follows:-

1. Remove the Logo plate (item 1, Fig. 2.2) from the instrument. Use a small flat bladed screwdriver to release the locking tabs at the top and bottom centre and gently pull it away.

If a lineariser (item 2, Fig. 2.2) is already fitted it must be removed, the safest way to do this is to remove the front panel assembly.

2. Remove the front panel, by unscrewing the six screws securing it in place. Two on the bottom front edge and four along the top back edge (two of which are recessed).

3 Gently pull the front panel away from the unit, taking care not to strain the wires. The fuel control knob will be pulled off in the process.

4 The two locating pegs for the lineariser can now be located at the top of the PCB. Gently and evenly push them both to release the lineariser from the PCB.

5 Refit the front panel assembly and fuel knob.

6 The module is supplied with the lineariser enabled, if you do not require this function:-

Interface upto #21231 Before fitting the interface slide the red switch to the right (when viewed from the top with the black overlay nearest to you).

Interface from #21807 After fitting the interface into the instrument, turn on the instrument and after the ignition sequence press the ‘Select’ button while moving the ‘Filter Selector’ to K or Ca. When ‘Select’ is released the buzzer will stop and ‘C’ will no-longer be illuminated.



7 Fit the new module by aligning the pegs in the locating holes of the PCB and pushing the module fully home. Be careful to align the gold pins so they do not get bent before pushing too hard.

8 Connect the printer/computer cable by pushing the mating end onto the socket at the left-hand end of the module.
