Page 3: Section 1
SECTION 1 Connecting the I/O Board The I/O Board options for the Series LV Emergency Lighting Central Inverter can have a varying amount of input and output connections. The two most common versions are a version with 3 inputs and 3 outputs, and another version with 6 outputs. -
Page 4: Output Connections
Series LV system, which is featured on advanced systems. The following section outlines how to set input and output functions through the LV display panel. See the 115107 LV Series Manual for further instructions on the display operation of the LV system. -
Page 5: To Set An Output Function
The menu displays the state of the contacts as well as the function they are set too. Default settings: The following table outlines the default settings for different versions of the LV series I/O Option board. Table 2.1: Default settings 6 Output Option... -
Page 6: Section 3
LV series emergency lighting system. If the loadshed feature of the LV series unit is enabled, it will disable the normally off relay after a set amount of time regardless of the active state of an input set to the normally off relay function. -
Page 7: Section 4
SECTION 4 Output functions defined Output function can be broken into three categories, status/alarms, set points, and other. Output Set Point Functions: Set point outputs are output functions that require the user to set limits. Input Voltage, Input Frequency, Output Voltage, Output Current, Battery Voltage, Battery Temperature, Ambient Temperature, and On Inverter Timer are all set point outputs. -
Page 8: Status/Alarm Functions
Engages the output relay when the LV Series unit is in emergency backup. Test Engages the output relay when the LV Series unit is conducting an inverter test. Norm Off Active Engages the output relay when the normally off relay is powered. -
Page 9: Other Output Functions
Other Output Functions: Input Active, Switched Output, and Transfer Delay are other functions available for the output contacts. If an output is set to Input Active, it will be powered as long as the same number input is powered. For example, if input 1 is powered with a 90-277Vac signal, output 1 will be powered. -

Special considerations: This switched output solution requires that the switched line mentioned is the same phase as the input to the LV Series unit. This solution can not be accomplished with voltages of different phases or magnitudes without damaging the LV system. -
Page 11: Non-Isolated Switched Output With The I/O Board Option
Special considerations: This switched output solution requires that the switched line mentioned is the same phase as the input to the LV Series unit. This solution can not be accomplished with voltages of different phases or magnitudes without damaging the LV system. - Page 12 After wiring is completed, the input needs to be set to Switched Input in the I/O settings menu in the display. This causes the output contact to switch whenever there is a 90-277Vac voltage across the input connection of the I/O Board, or the LV Series unit goes into emergency backup. Figure 5.3 Special considerations: This switched output solution is completely isolated.

LV Series unit goes into emergency backup. During an emergency, OUT1 switches the load source from utility AC to the output of the LV Series unit and OUT2 opens the dimmer signal, causing the ballast control to switch to full brightness. -
Page 14: Led Dimmer Application (Full Brightness)
After wiring is completed, set OUT1 to On Battery in the I/O settings menu in the display. This causes the output contacts to switch whenever the LV Series unit goes into emergency backup. During an emergency, OUT1 opens the dimmer signal, causing the ballast control to switch to full brightness. -
Page 15: Led Dimmer Application (Minimum Brightness)
After wiring is completed, set OUT1 to On Battery in the I/O settings menu in the display. This causes the output contacts to switch whenever the LV Series unit goes into emergency backup. During an emergency, OUT1 shorts the dimmer signal, causing the ballast control to switch to minimum brightness. -
Page 16: Section 7
SECTION 7 Combination of output contacts If multiple outputs of the I/O Board are used, a combination of logic can be accomplished. The outputs can be connected in parallel, series, or a combination of both. Application example #1: Want to have a light turn on when the utility fails and when the battery temperature is too high? Solution example #1: Wire the light to the normally open (NO) of an output set to Input Voltage in... -
Page 17: In Series
In series: The following picture illustrates how to wire any number of outputs in series. If wired as shown in the picture, the load will receive utility voltage only if every output is powered. If one of the outputs is wired to the NC position, instead of the NO position, the load will receive power as long as all of the outputs are powered except that specific output. -
Page 18: Section 8
SECTION 8 Zone Monitor Figure 8 illustrates a zone monitor application where a separate zone and/or fire alarm panel can force the Emergency Lighting Inverter into an emergency state even if its AC power is within acceptable limits. The AC input that is feeding the room lighting is connected directly to the Isolated I/O Board Input Sense or in the case of a fire alarm panel connected through a normally closed dry contact from the fire alarm panel as shown. - Page 19 Notes: 115159H - LV I/O OPTION...
