3.4 Programming Magnet Operating Instructions
Operator interface to UniTox™ gas detection products is via magnetic switches located behind the UTM
faceplate. Two switches labeled “PGM 1” and “PGM 2” allow for complete calibration and programming.
Figure 11 Programming Magnet
A magnetic programming tool is used to operate the magnetic switches. Switch action is defined as
momentary contact, 3-second hold, and 15-second hold. In momentary contact use, the programming magnet
is waved over a switch location. In 3-second hold, the programming magnet is held in place over a switch
location for 3 or more seconds. In 15-second hold, the programming magnet is held in place over a switch
location for 15 seconds. Three (3) and fifteen (15) second holds are used to enter or exit calibration and
program menus while momentary contact is used to make set-point adjustments. The location of “PGM 1” and
“PGM 2” is shown in Figure 12.
NOTE: If, after entering the calibration or program menus, there is no interaction with the
menu items for more than 30 seconds, the sensor will return to its normal operating condition.
