1. 3 2 2 Inputs and outputs The list of input and output functions in section 3 2 3 is handy instrument to help you keep track of which inputs and outputs you will need to configure Analogue inputs Analogue inputs must refer to an A gnd terminal placed in the same terminal block as the input being wired Analogue inputs can depending on the configuration be used for either PT1000 temperature sensors or for 0 10 V DC analogue input signals for example from a pressure transmitter Digital inputs Digital inputs must refer to C on terminal 4 Digital inputs may only be wired to voltage free contacts Any external voltage applied to digital input may harm the unit Universal inputs universal input can be configured to act as either an analogue input or as digital input universal input configured as analogue input must refer to an A gnd terminal placed in the same terminal block as the input being wired universal inputs configured an analogue input can depending on the configuration be used for either PT 1000 temperature sensors or for 0 10 V DC analogue input signals for example from a pressure transmitter universal input configured as digital input must refer to C on terminal 4 It may only be wired to voltage free contacts Corrigo E Heating manual revision G Chapter Installation and wiring 8 Analogue outputs Analogue outputs must refer to the A gnd terminal placed in the AO2. 0O YV Down There are seven buttons 4 arrow buttons which will be called UP DOWN RIGHT and LEFT The menus in the Corrigo E are organized in a horizontal tree structure The UP DOWN buttons are used to move between menus at the present menu level The RIGHT LEFT buttons are used to move between menu levels When changing parameters the UP DOWN buttons are used to increase decrease the value of the parameter and the RIGHT LEFT buttons to move between digits within the parameter e The OK button is used to confirm the choice of a parameter setting e The C button is used to abort an initiated parameter change and restore the original value e The ALARM button marked with a red button top is used to access the alarm list Corrigo Heating manual revision Chapter 6 Display LEDs and buttons 22 6 4 Navigating the menus The start display the display normally shown is at the root of the menu tree Pressing DOWN will move you through the menu choices at this the lowest level UP will move you back through the choices To enter higher menu level use UP or DOWN to place the display marker opposite the menu you wish to access and press RIGHT If you have sufficient log on privileges the display will change to the menu you have chosen At each level there may be several new menus through which you may move using the UP DOWN buttons Sometimes there are further submenus linked to a menu or menu item T
