Quick Start Guide

DTC Digital Time Clock

Welcome to the nLight Digital Time Clock (DTC) Quick Start Guide. This guide provides quick instructions of how to properly mount the nDTC, and to configure and create schedules on your new device.

Mounting Instructions

To mount, the faceplate must be detached from the backplate. This will require an appropriately sized tool (i.e., flat-head screwdriver) that can fit in the release tab.
Using the appropriately sized tool, press in the release tabs on each side of the device until the backplate is noticeably released.
Pull the backplate out from the bottom, away from the faceplate, as pictured.
Device should be separated into two pieces, backplate and faceplate. The backplate will be used to mount onto a wall gang box.
Pull all wires out of the wall and run them through the central hole of the backplate. Screw the backplate onto the wall.
Plug the wire(s) into the connector(s), then gently push the excess wiring back into the wall. Reattach the front plate and ensure that it clips tightly in place. Tighten the security screw, if applicable.

Mounting DTC Bracket into ARP Instructions (sold separately)

Follow ‘Mounting Instructions’ Steps 1-4 for removing the back plate from the nDTC.
Using the (2) supplied self-tapping screws, fasten the nDTC back plate to the bracket door (there are two pre-drilled holes). Make sure the plate is straight when screws tightened.
Align the bracket with the pre-cut slots and insert the bracket’s tabs, making sure the screw hole aligns with the pre-drilled hole in the panel’s back plate. Fasten bracket to the panel with supplied screw.
Snap nDTC unit to the back plate.
Locate the 2 pre-assembled wires. Insert the end with 2 wires heat-shrunk together into the terminal block of the power supply. The brown-and-red wire assembly goes into the red ‘24 VDC’ block, and the brown-and-blue wire assembly goes into the blue ‘Common’ block.
Make opposite connections (both brown) to the nDTC grey terminal block on the back of the nDTC. For all connections, make sure wire leads are inserted fully and grasped the terminal blocks, so that they do not easily pull out.
Using the supplied Cat5e cable, find the 90 degree end with the tab on top. Insert this end into one of the nDTC’s available RJ45 ports.
Connect the opposite end of the Cat5e cable into the ARP panel’s control card.
Install the terminator (supplied with ARP panel) into available Cat5e port on either ARP or nDTC; or, Cat5e cable to the next device in the nLight Zone.
Route these wires thru pre-installed wire guide on the back of the bracket door.
Close the bracket door, making sure wires are not pinched or pulled, and tighten the thumb-screw.
Restore power to the panel, and verify nDTC powers up.

Start Event is the first event that runs when the schedule is triggered, and is required for a schedule to run. Select a time within the schedule’s date(s) when the start event should begin. Users will also be able to Set Light Levels to either channels or individual output devices connected to the lighting control zone, and can choose to Enable/Disable Inputs during the event.
End Event is the last event that runs when a schedule is triggered. Unlike the start event, the end event is optional. Users have the option to set the Action to Do Nothing. By selecting this option, the actions of the start event will continue past the schedule’s end date, unless overwritten by another schedule’s actions.p
