MODULE PROGRAMMING OPTIONS
Certain module functions can be programmed by using the mode selector switch and a front panel toggle
switch. To enter the programming mode, press and hold the toggle switch to the right (PGM) position for
approximately two seconds until the Gate 1 LED starts to flash. This indicates that the module is in the
programming mode. By briefly pressing the toggle switch to the right and releasing it, the program group
can be selected. The Gate 2, Trig 1, and Trig 2 LEDs will successively flash, indicating that the
corresponding program group is selected. There are four program groups with 16 options per group. The
table below describes the functions controlled by this arrangement.
Once the option is programmed, its current state is stored in a non-volatile memory and will be restored
the next time the module is powered. One of the program options can be selected to return all settings to
the factory defaults.
Within a group, to select the option to be programmed, turn the mode selector switch to the appropriate
number and then press the toggle switch to the right (PGM) position for approximately two seconds or
until the LED stops flashing and remains lit. Then release the toggle switch. The LED will go off after
