Additive Feeders Chapter 4: Operation 31 of 55
Resetting the Unit to Un-Programmed State
The factory-default settings can be easily restored using either of two methods. Both
methods require the Program Enable jumper to be in the “On” position. The first is to apply
power to the unit with both the Enter and Down buttons pressed for 3 seconds. The second is
to change the value of parameter 95 to 5.
JP1 (Program Enable Jumper)
The JP1 jumper is located under the dust cover on the back end of the upper board. When the
jumper is set to the "Off" position, all programming features are locked out to the front panel
user. When the jumper is in the "On" position, the programming parameters are open to
change. JP1 is shipped in the "Off" position.
