1 Introduction
This manual explains the installation and maintenance of Daktronics Analog Clocks.
This manual is not specic to a particular installation. Project-specic 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.
Resources
Figure 1 illustrates a Daktronics drawing label.
This manual refers to drawings by listing the last
set of digits. In the example, the drawing would
be referred to as DWG-1007804. All references to
drawing numbers, appendices, gures, or other
manuals are presented in bold typeface.
Any drawings referenced in a section are listed
at the beginning of it as shown below:

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-specic 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.

CAUTION: Only qualied individuals should perform power routing and termination.
Electrical contractors are responsible for ensuring that all electrical work meets or
exceeds local and national codes�
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.
