Mounting

Reference Drawings: Attachment- DA-1100-4 to
DA-1004-XX DWG-272683

Each analog clock will be mounted differently depending on the
diameter of the clock face and the surface to which it will be
attached. DWG-272683 in Appendix A shows the typical location and
hardware required when mounting an analog clock to a standard
Daktronics arch truss. For all other types of mountings, refer to
contract-specific shop drawings or system riser diagrams.

Removal & Replacement

Instructions for removal and replacement of the analog clock
will depend on the specific installation and should be outlined in
the project-specific information.

Small Clocks

Instructions for installation of small clocks will depend on the
specific installation and should be outlined in the
project-specific information.

Large Clocks

Instructions for installation of large clocks will depend on the
specific installation and should be outlined in the
project-specific information.

3 Electrical Installation

Warnings and Disclaimers

Before beginning electrical installation, ensure all power to
the area is turned off and the area is safe to work in. Failure to
follow proper safety procedures can result in injury or death.
Daktronics is not responsible for any damages or injuries resulting
from improper installation or use of their products.

Clock Control Installation

Instructions for clock control installation will depend on the
specific installation and should be outlined in the
project-specific information.

4 Replacement Parts

Replacement Fuses

If a fuse needs to be replaced, refer to the project-specific
information for the correct replacement fuse and instructions for
replacement.

Routine/Preventative Maintenance

Perform routine maintenance as outlined in the project-specific
information to ensure proper functioning of the analog clock.

1 Introduction

This manual explains the installation and maintenance of Daktronics Analog Clocks. This manual is not specific to a particular installation. Project-specific information takes precedence over general information found in this manual.

Important Safety Instructions

· Read and understand all instructions before beginning the installation process.
· Disconnect power when not in use or when servicing.
· Do not modify the structure or attach any panels or coverings to the clock without the express written consent of Daktronics.
· Do not disassemble control equipment or electronic controls of the clock; failure to follow this safeguard will make the warranty null and void.

Mounting
Reference Drawings: Attachment- DA-1100-4 to DA-1004-XX ………………………………………………….. DWG-272683
Each analog clock will be mounted differently depending on the diameter of the clock face and the surface to which it will be attached. DWG-272683 in Appendix A shows the typical location and hardware required when mounting an analog clock to a standard Daktronics arch truss. For all other types of mountings, refer to contract-specific shop drawings or system riser diagrams.
Note: For installation procedures of the truss itself, refer to the Outdoor Decorative Accent Installation Manual (ED-16076), available online at www.daktronics.com/ manuals.

3 Electrical Installation
CAUTION: Only qualified individuals should perform power routing and termination.
Warnings and Disclaimers
· Ensure that all electrical work meets or exceeds all local or national electrical codes. · Provide the required power to the display as listed on the product labels,
specifications, or site-specific riser drawings. The conductor size may vary based on the length of the power run. · Consider implementing a separate circuit for the display using an isolation transformer or dedicated transformer. · Daktronics assumes no liability for any issues caused by line voltage fluctuations or other improper power conditions.
Clock Control Installation
Reference Drawings: System Riser: Clock Assy…………………………………………………………………………. DWG-263976
The clock control system consists of two parts: a controller and a motor mechanism. The controller is used to set the current time and send power to the motor mechanism, which in turn rotates the clock hands. DWG-263976 in Appendix A illustrates a typical wiring diagram for 115 and 230 VAC installations. For additional clock installation and setup information, refer to the 99B-MI User’s Manual, located online at www.electrictime.com/ services/support. 1 After the motor mechanism is mounted to the rear of the clock face, install the clock
hands to the front of the clock face with both hands pointing up at the 12:00 position. 2 Determine the controller location and mount per manufacturer’s instructions.
Note: The controller and motor may be located no more than 100′ (30.5 m) away from each other.
3 Connect power in conduit to the controller. 4 Connect power in conduit from the controller to the motor mechanism. 5 Set the clock to the correct time per manufacturer’s instructions.
