Section VI
Opening the Service Door
Manually programming the Electronic Control often
requires the user to open and close the service door.
Opening and closing the service door trips a switch
allowing access to various programming options,
diagnostics and audit capabilities.
The service door is located on the top of the meter
case. See Figure 3.
After opening and closing the service door, the
programmer has 4.25 minutes to begin programming.
If a SELECT CYCLE pad has not been pressed in that
time, the control will revert back to the “Ready” mode.
See Figure 2.
