Setting the Driver Address
Reference Drawings:
Address Table; Rotary Switches H and L ........................................................ DWG-1198765
Since the same LED drivers can be used for many
display models, each driver must be set to receive
the correct signal input, or address, for the model
being used.
Addresses are set through the S2 (L) and S3 (H)
rotary switches on the driver ( Figure 8 ) using a small
flathead screwdriver.
The MS-2113 will always be set to address 11 , where
H = 0 and L = B.
Replacing Batteries
Reference Drawing:
Battery Service- MS-2113.................................................................................. DWG-3276260
As the batteries age, they may lose capacity to sufficiently operate the display, even
on a full charge. When replacement becomes necessary, use the same brand of
battery as the original equipment. Similar batteries may be used as long as they meet
the specifications for the display. If a different brand must be used, be sure that the
terminals are oriented the same as in the original to ensure a proper connection. Refer to
Replacement Parts (p.19) for part numbers of batteries and fuses.
DWG-3276260 in Appendix A illustrates battery service. Mounting brackets hold the
batteries in place at the bottom of the display. The bracket is designed to hold batteries
measuring 7" high, 6.5" wide, and 5" deep (178 mm, 165 mm, 127 mm). The bracket is not
designed to support a battery of different dimensions.
To replace the batteries:
1� Open the back panel as described in Component Locations & Access (p.16) .
2� Use a 3/8" socket or nut driver to unfasten the four nuts securing each battery bracket
to the display studs and remove the brackets.
3� Remove the screws securing the wires to the battery terminals. Disconnect the
negative (–) terminal first followed by the positive (+) terminal.
4� Remove the battery from the display.
5� Reverse the procedure to install new batteries. Connect the positive (+) terminal first
followed by the negative (–) terminal.
Important Notes:
• During service, do not allow the battery terminals to touch any metal surface.
When reinstalling, make sure the terminal wires are connected correctly. Improper
connection may result in injury or damage to display components.
• The batteries in these products contain lead. Do not dispose of the batteries in a
municipal waste system at the end of their useful life. Doing so may be a violation
of local, state, or federal environmental regulations. Please return the batteries to a
battery recycling center or battery retailer.
