    Zenex-ultra User Manual Section 2 BASIC OPERATIONS MAIN DISPLAY MODE After the power-up display sequence, the upper readout starts showing the measured PV (Process Value) and the lower readout displays the SP (Setpoint) in 0.01°C Resolution. This is called the MAIN display mode and this is the one that shall be used most often. The MAIN display mode is depicted in Figure 2.1.

  • Page 5: Pages & Parameters

    Zenex-ultra User Manual Section 3 PAGES & PARAMETERS ORGANIZATION The controller requires various user settings that determine how the controller will function or operate. These settings are called parameters. The various parameters have been grouped as shown in Table 3.1. Each group is assigned a unique PAGE NUMBER for its access and the parameters within each group are presented depending on the function(s) selected.

If adjusting a numeric value; depressing the UP/DOWN key once, increases/decreases the parameters value by one digit. For parameters having a series of options, depressing the UP/DOWN key once takes you to the next/previous option. In each case, keeping the UP/DOWN key pressed speeds up the rate.

    Solid State Relay (SSR) Note: In the zenex-ultra, the Temperature Range is restricted to -19.99 to +102.9°C. This Temperature Range is fixed and not available as settable parameter. The 0.01°C Resolution is available upto 99.99°C. After this, the resolution automatically changes to 0.1°C.

  • Page 8: Configuration Parameters

    Zenex-ultra User Manual Section 5 CONFIGURATION PARAMETERS The Configuration parameters are contained in PAGE-11 and are factory set to the appropriate default values. However, for specific installations the user may need to alter the values. Altering the configuration parameter values affect either the measured PV and/or the control algorithm implemented by the controller.
