Aux Relay Contact HOUOL Pin 7 Aux Relay Contact 3 2 1 Up Down Sequence Control Inputs The SEQ can be controlled by a DC voltage in the range of 5V to 30V by a contact closure such as a relay or by a switch In this manual the terms momentary and latching are used when describing Switches A momentary switch is considered to be a switch which provides a connection only while it is actually held pressed and a latching switch is considered to be a switch which remains in either the on or the off state like a light switch Momentary switches are preferred for use with the SEQ since multiple control locations can be used and also because some of the functions of the SEQ are not available when a latching switch is used see programming section Switches with gold contacts are recommended for the best long term reliability The type of input is selected totally through programming making the electrical connections straightforward The six control options are discussed below a DC VOLTAGE The SEQ will power up when the voltage is present and power down when there is no voltage Connect the positive wire to the Up input and the ground or negative wire to Common Program the input for 5 30 V DC b CONTACT CLOSURE The SEQ will power up when the contacts are closed and power down when the contacts are open Connect the two wires from the contacts to Up and Common Program the input for Latchin2.

7. 1 6 1 2 Controlling the SEQ The SEQ is primarily designed to be used with momentary action switches A momentary switch is a Switch where the contacts are closed only while the switch is actually pressed such as a push switch Using momentary switches allows several switches to be connected in parallel so that the SEQ can be controlled from multiple locations A single push switch would cause the unit to power up on the first press and then power down on the second press A dual momentary switch such as a center biased rocker or two separate push switches one for UP and the other for DOWN can also be used with equal versatility It is up to the installer to choose the configuration Whatever type of switch is used Switches with gold contacts are recommended for the best long term reliability Where there are multiple control locations it is advantageous to use the 12V dc output to drive LEDs so that there is an LED at each control location Up to four LEDs running at 10mA each can be powered from the 12V dc output Each control location then has an indication of the operational status of the SEQ regardless of which location last initiated power up or power down The SEQ also supports latching switches contact closure and applied DC voltage but these types of input cannot be used with multiple control locations they are intended primarily for a small system or for hook up to a central controller The front panel push button will not work w

Confirmation Connection The SEQ offers two ways to provide confirmation feedback to a central controller a 12V DC output and isolated relay contacts Confirmation tells the controller that the SEQ has indeed powered up or that it is fully powered down If the 12V DC output and the Aux Relay contacts are not used for any other function you will be free to choose whichever provides the best interface for the application However if one of these outputs is used for another function you will have to use the one that is available To use the 12V DC output for confirmation connect 12V DC output to the positive input of the controller and Common to ground The output will be at 12V when all banks are powered up and will be zero when all banks are powered down Program 12V DC Output for Confirm Note that the SEQ common terminal is shared between the inputs and the 12V DC output If you need relay contacts for confirmation and you are using the Aux Relay for another function you can connect a small relay between the 12V DC output and common The relay coil current must not be more than 40mA and you must connect a diode such as a 1N4148 or 1N4002 across the relay coil cathode to 12V dc to Suppress the back EMF from the coil If you need assistance with this please contact our technical Support department To use the Auxiliary Relay contacts for confirmation connect the contacts to the input of the controller The relay contacts will be
