nLight® Digital Time Clock (DTC)
Quick Start Guide
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.
Welcome to the nLight Digital Time Clock (DTC) Quick Start Guide. This guide provides a quick explanation of how to properly mount, configure,
and create schedules on your new DTC device.
Mounting Instructions
1 2
Pull the backplate out from the bottom, away fromthe
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.
3 4
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 thesecurity
screw, if applicable.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The nLight Digital Time Clock (DTC) is a sophisticated device designed for managing lighting schedules and control within a building environment. It serves as a central interface for users to configure and automate lighting events, offering both normal and holiday scheduling capabilities.

Function Description

The primary function of the nLight DTC is to provide precise, time-based control over connected lighting systems. It allows users to create detailed schedules that dictate when lights turn on or off, adjust light levels, and enable or disable specific switches and sensors. This automation helps optimize energy consumption and enhance the convenience of lighting management. The device supports both standard daily/weekly schedules and specialized holiday schedules, ensuring flexibility for various operational needs. Its intuitive interface guides users through the setup process, from initial device configuration to the creation of complex lighting routines. The DTC integrates with nLight control zones, allowing it to manage individual output devices, channels, and input devices such as occupancy sensors and photocells.

Usage Features

The nLight DTC offers a comprehensive set of features for ease of use and robust control:

• Mounting and Installation: The device is designed for straightforward installation. It consists of a faceplate and a backplate. The backplate attaches to a standard wall gang box, and the faceplate then clips securely onto the backplate. Wires are routed through a central hole in the backplate and connected to the appropriate terminals before the faceplate is reattached. A security screw can be tightened to ensure the device remains firmly in place.

• Initial Configuration: Upon first use, the DTC guides the user through an initial setup wizard. This includes:

  • Location Setting: Users can specify the device's geographical location by entering country, state, and city, or by providing latitude and longitude coordinates. This information is crucial for accurate astronomical scheduling (sunrise/sunset).
  • Date and Time Setting: The device allows for precise setting of the current date and time. It also includes options for configuring Daylight Saving information, such as start and end days and minute offsets, to ensure schedules adjust automatically.
  • Time Zone Setting: Users can select the appropriate time zone for the device, further enhancing the accuracy of time-based operations.
  • Administrator PIN Creation: A six-digit administrator PIN must be created during initial setup. This PIN is essential for accessing and modifying schedules and other sensitive settings, providing a layer of security to prevent unauthorized changes. The device does not come with a default PIN, emphasizing the importance of creating one immediately.

• Scheduling Capabilities: The DTC supports two main types of schedules:

  • Normal Schedules: These are designed for regular, recurring lighting events. Users can define a schedule name, select specific days of the week (e.g., Monday through Friday) and a date range (e.g., January 1 to December 31) during which the schedule will be active.
  • Holiday Schedules: These allow for special lighting routines during holidays or custom events. Users can select from a list of major US holidays (e.g., Christmas, New Year's Eve) or create a "New Custom Event" for unique occasions. Holiday schedules can be configured for single dates or date ranges.

• Schedule Creation Workflow: The process of creating both normal and holiday schedules follows a consistent, step-by-step approach:

  • Accessing Schedules Dashboard: After logging in with the administrator PIN, users navigate to the "Schedules" dashboard, where they can select either the "Normal" or "Holiday" tab.
  • Adding a New Schedule: Users initiate schedule creation by selecting "Add Normal Schedule" or "Add Holiday Schedule."
  • Defining Schedule Parameters: This involves entering a schedule name, selecting the days it runs, and specifying the active date range. For holiday schedules, users choose predefined holidays or create custom events.
  • Start Trigger Configuration: The "Start Trigger" is a mandatory component of any schedule. It defines the initial action that executes when the schedule begins. Users can set a specific time or use astronomical triggers (e.g., Sunrise +15 minutes, Sunset -30 minutes). Within the start trigger, users can:
    • Set Light Levels: Adjust light levels for individual channels or specific output devices within the control zone. This allows for granular control over brightness.
    • Enable/Disable Switches: Control the operational status of connected switches, such as wall switches or occupancy sensors.
    • Enable/Disable Sensors: Manage the active state of various sensors, like occupancy sensors or photocells, influencing how they interact with the lighting system.
  • End Trigger Configuration: The "End Trigger" is an optional component that defines the actions taken when a schedule concludes. Similar to the start trigger, users can set a specific time or astronomical trigger. A key option for the end trigger is "Do Nothing," which means the actions initiated by the start event will continue indefinitely until overwritten by another schedule. This provides flexibility for maintaining specific lighting states.

• Intuitive Interface: The device features a clear, graphical user interface with on-screen keypads for PIN entry and selection menus for various settings. Visual cues, such as checkmarks for successful operations and 'X' marks for errors, provide immediate feedback to the user. The step-by-step guidance ensures that even complex configurations can be managed effectively.

Maintenance Features

While the nLight DTC is designed for reliable, long-term operation with minimal direct maintenance, certain aspects contribute to its upkeep and longevity:

• Firmware Updates: Although not explicitly detailed in this guide, devices of this nature typically support firmware updates to introduce new features, improve performance, or address any potential issues. These updates are usually managed through the nLight system or a connected network.
• Security PIN Management: The administrator PIN acts as a security feature, preventing unauthorized access to critical settings. While not a maintenance task in the traditional sense, managing this PIN (e.g., changing it periodically or ensuring it remains confidential) is crucial for maintaining the integrity of the lighting control system.
• System Integration: The DTC operates as part of a larger nLight system. Maintaining the overall health and connectivity of the nLight network, including other nLight devices and communication infrastructure, indirectly contributes to the optimal performance of the DTC.
• Troubleshooting Guidance: The guide implies that the device provides clear feedback during setup and operation, which aids in basic troubleshooting. For instance, if PINs do not match during creation, an immediate message is displayed, guiding the user to correct the input.

In summary, the nLight Digital Time Clock (DTC) is a robust and user-friendly device that empowers building managers and occupants to precisely control and automate their lighting environments, leading to enhanced energy efficiency, convenience, and operational flexibility. Its comprehensive scheduling capabilities, secure access, and guided configuration process make it a valuable component of any modern lighting control system.
