Programming Magnet Operating Instructions
Operator interface to UniTox™ gas detection products is via magnetic switches located behind the UTM
enclosure cover. DO NOT remove the cover to calibrate or change programming parameters. Two switches
labeled “PGM 1” and “PGM 2” allow for complete calibration and programming without removing the
enclosure cover, thereby eliminating the need for area de-classification or the use of hot permits.
Figure 11 Magnetic Programming Tool
A magnetic programming tool (see figure 5) is used to operate the 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 4
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.
