SETTING UP... 5.4 Indicat Panel The programming controls, upper and lower displays and indication l.e.ds are located on the front panel of the display unit see Fig. 14. 5.4.1 Controls Fig. 14 The program controls comprise three tactile membrane switches, requiring only moderate finger pressure f operation, and a rotary bit-generat. Control functions are as follows: 'Page Advance' switch used to advance to the next program page (see Fig. 14). 'Parameter Advance' switch used to advance to the next parameter within a program page (see Fig. 14). At the beginning of each programming page, i.e. the page header, both displays are used to describe the particular page being viewed. When parameters within a page are being viewed the upper display shows the parameter and the lower display shows the value setting f that parameter. Note. A flashing decimal point on the upper display is used to indicate any change to the value/parameter on the lower display, i.e. using the 'Rotary Bit-generat'. The l.e.d. is extinguished only when the value/parameter is sted using the '' switch. 5.4.3 L.E.D. Indication Fig. 14 There are six l.e.d. indicats on the front panel but only two are used in this application: '' switch used f sting the programmed parameters and values into indicat's the non-volatile memy. If any value/parameter is changed but not ''ed, the old parameter value is retained see Note in Section 5.4.2. 'Rotary Bit-generat' rotary control used f: a) Increasing decreasing a parameter value b) Stepping through a selection of parameters. A1 flashes if Alarm 1 is in the alarm state see Section 5.5.4. A2 flashes if Alarm 2 is in the alarm state see Section 5.5.4. 5.5 Programming CAUTION. When the apparatus is connected to its supply, terminals may be live and the opening of covers removal of parts (except those to which access may be gained by hand) is likely to expose live parts. A/M 'Auto/Manual' switch not used in this application. 5.4.2 Displays Fig. 14 There are two 6-digit fourteen-segment 'starburst' displays which provide alpha-numeric infmation during nmal operation and when programming. In nmal operation the instrument displays the Operating Page (see Section 5.5.2) which is not affected by the Security System (see Section 5.5.5). N.B. To return to the Operating Page at any time, operate the 'Page Advance' switch and then operate the '' switch. Lower Display Upper Display '' Switch L.E.D. Alarm L.E.D.

...SETTING UP 5.5.1 General The programming procedures are used to make changes to the operating parameter values and f calibration see Fig. 15 f the overall programming chart. Any changes to the operating parameters are implemented using the 'Rotary Bit-generat' and the '' switch see Fig. 14. Note. The indicat responds instantly to any parameter changes, i.e. befe the '' switch is used. However, if any change is not ''ed the old parameter is retained once that particular parameter is no longer displayed, i.e. by advancing using the 'Page Advance' 'Parameter Advance' switches. A Security System is used to prevent tampering with the programmed parameters by restricting access to any, all, of the programming pages (except the Operating Page). All users have access to the Operating Page. 'Secured' pages can only be accessed using a Security Number which can be set at any value between 0 and 1999 see Section 5.5.5.

A security system is used to prevent tampering with the programmed parameters by inhibiting access to any, all of the programming pages. 'Secured' pages can only be accessed using a Security Number which can be set to any value between 0 and 1999 see Section 5.5.5. The controller is despatched with the passwd set to '0'.

...SETTING UP 5.5.6 Kent Page This is nmally a hidden page, but it can be selected f parameters which only need to be set up during commissioning at long intervals. The page is made available by rotating Link 4 on the display unit process board. When the instrument is switched on, the Kent Page will appear after the Access Page, and operates in a similar manner to the other pages. When the Kent Page parameters, as shown below, have been set up, Link 4 can be rotated back to its iginal position and the page will not appear when the instrument is next switched on. The Kent Page contains frames to calibrate the analogue retransmission output, and, f the Hydrogen Purity Monit only, a frame to select the display full scale (80% 85%).
