Overview

The ILLUMRA E9X-RUV-4IBTP controller contains a dry contact output controlled by wireless device inputs. A common application is to link it with the ILLUMRA E9T-MDCCP wireless window / door sensors to save energy by preventing HVAC equipment from running when windows or doors are open. 


Operating Description

The E9X-RUV-4IBTP can be linked to one or more window/door sensors. The dry-contact output will be CLOSED when all of the sensors are CLOSED (magnet is close to the sensor) and the dry-contact output will be OPEN when any of the sensors are OPEN (magnet is NOT close to the sensor). Follow instructions below to configure the devices for this operating scenario.


Configuration Instructions

The 20A relay is configured with 2 blue wires connected to an isolate relay output that can be used to interface with a dry-contact closure. The term "Dry-contact" means that the relay contacts are fully isolated and are not connected to an internal voltage source - the 2 blue wires are connected to each other (low resistance) when the relay is ON and the 2 blue wires are disconnected (high resistance) when the relay is OFF. Because they are "dry-contacts", this relay can be used to interface with a secondary signal or system of the same or AC different voltage or a DC voltage if DC mode is activated (see instructions below). The 20A controller still requires a connection to an operating supply voltage of 100-277VAC (white and black wires) while the relay contact (blue wires) can be connected to a different signal or circuit, as needed.


Applications

This flexibility allows the controller to be used in many applications, including:

  • Line voltage switching - To use the controller for switching a load that will connect to the same line voltage circuit that powers the device, connect one Blue wire (input - either blue wire works) to the Black wire and to the incoming Line voltage. The second blue wire will be the switched voltage output to power the load. The White wire will be connected to either Neutral or a separate phase line. Link to a switch or sensor for ON/OFF control.
  • HVAC interlock - The 20A controller is powered from 100-277VAC and the dry contact interrupts power to the thermostat. Link to one or more magnet contact sensors to disable HVAC when outside windows or door are left open.
  • Momentary pulse closure- Use for motor control, motor starter and other applications - 20A controller is powered by 100-277VAC and the dry contact is configured in momentary mode so that the contact is closed while the switch is held and releases when the switch releases. Configuration options: 
    • Field or factory activate DC mode for use with DC signals (AC mode is the default)
    • Factory only - selectable Minimum ON timer to stretch the pulse so it is on for a minimum time anytime the switch is pressed
    • Factory only - Other factory configured timers available for specific applications: Auto-OFF, Auto-On, Minimum On, Maximum On, On Delay, Minimum Off, Maximum Off, Off Delay.


Operating Modes


DC Mode

By default the controller supports AC modes and if used with DC loads, the output will latch ON and only turn OFF when power is removed from the dry contact input. To use with DC loads, either request that it be pre-configured at the factory or field activate DC mode using commissioning software or the following pushbutton sequence:


DC Mode activation with push button sequence: (for E9X-RUV-4IBTP)

  1. Power the device
  2. Hold down the menu button for at least 15 seconds. After the LED blinks amber 3 times, release. The advanced menu is now active. If the relay is clicking on and off, the button was not held long enough. Power cycle or wait 30 seconds for clicking to stop and try again.
  3. Press and release the Select button 5 times. The LED should be blinking a 6 amber blink pattern
  4. Press and release the Menu button, it should now be blinking a single green blink pattern.
  5. Press and release the Select button 5 times, it should now be blinking a 6 green blink pattern
  6. Press and release the Menu button. it should now be blinking a red pattern. If the LED is showing a 1 red blink pattern, press and release the select button 1 time. LED should now be showing a 2 red blink pattern. 2 blinks = DC load, 1 blink = AC load (default)
  7. Press and release the Menu button. The LED should show solid green for a few seconds then start its blink pattern again.
  8. Exit the advanced menu using 1 of 3 options: 
    1. Power off the device (configuration change was saved in step 7 and will not be lost), 
    2. Press and hold the Menu button for 5 seconds to exit the current menu level. Repeat 2 times to fully exit the menu.
    3. Wait one minute for the device to exit the advanced menu automatically.


Invert Output

The E9X-RUV-4IBTP features a latching relay that stays in open or closed position even when power is removed, however the internal logic operates as a normally open relay by default. On power up, unless it has been programmed otherwise or linked to a switch, the relay will power up closed (ON). When linked to a window door sensor, the default behavior is for the contact to be closed (ON) when the sensor detects closed (magnet near the sensor) and will be open (OFF) when the sensor detects open (magnet away from the sensor). The behavior can be changed by adjusting the Invert Relay option per the instructions in the User Guide and copied here for convenience.


Change Invert Relay option with push button sequence:

  1. Power the device
  2. Hold down the menu button for at least 15 seconds. After the LED blinks amber 3 times, release. The advanced menu is now active. If the relay is clicking on and off, the button was not held long enough. Power cycle or wait 30 seconds for clicking to stop and try again.
  3. Press and release the Select button 5 times. The LED should be blinking a 6 amber blink pattern
  4. Press and release the Menu button, it should now be blinking a single green blink pattern.
  5. Press and release the Select button 4 times, it should now be blinking a 5 green blink pattern
  6. Press and release the Menu button. it should now be blinking a red pattern. 1 blink = Relay asserted Closed (default), 2 blinks = Relay asserted Open: inverted logic. To change the mode, press and release the select button 1 time. LED should toggle between the 1 and 2 blink pattern with each press of the button.
  7. Press and release the Menu button. The LED should show solid green for a few seconds then start its blink pattern again.
  8. Exit the advanced menu using 1 of 3 options: 
    1. Power off the device (configuration change was saved in step 7 and will not be lost), 
    2. Press and hold the Menu button for 5 seconds to exit the current menu level. Repeat 2 times to fully exit the menu.
    3. Wait one minute for the device to exit the advanced menu automatically.
