C1477B User Manual (UMC1477BR06) - 7 - © Omniflex2. SETTING THE CONFIGURATION SWITCHES2.1 IntroductionThe unit is configured for operation by setting the two 8-way set-up switches foundon the left hand side of the Omni8. The layout of these switches can be seen inFigure 1-3 – Side View showing 8-way Set-up Switches.SW1 is used to set the operational configuration of the Omni8.SW2 is used to set the sense of the eight input contacts – normally open ornormally closed.Each set-up switch has 8 individual miniature switches, numbered from 1 to 8.Each of these miniature switches can be referred to separately: for example, the 8miniature switches on SW1 are referred to as SW1-1 to SW1-8.2.2 Selecting the input senseCan either be set for normally open or normally closed.The input sense for each of the 8 input contacts is selected by setting thecorresponding switch of SW2. e.g. SW2-1 sets the contact sense for input 1 andSW2-8 sets the contact sense for input 8.When the switch is OFF (up) then the input is set to NORMALLY OPEN. (i.e. theinput will enter the alarm state when the input contact is closed.)When the switch is ON (down) then the input is set to NORMALLY CLOSED. (i.e.the input will enter the alarm state when the input contact is opened.)2.3 Selecting the alarm sequencesThe 8 inputs of the Omni8 operate as a single group of alarms all with the samealarm/display function, which can be any one of the available alarm/displaysequences listed in Table 2-1 (detailed block diagrams of each alarm/displaysequence are provided in section 8.)Set switch SW1-1 to SW1-5 according to the selected sequence in Table 2-1.The sequence switch settings can be changed at any time.Any sequence switch changes made while the unit is running in the normal modeof operation will cause the OMNI8 to revert to the power-up routine as describedin section 6.1. Press the ACKNOWLEDGE button to return the unit to normaloperation. |
