7.4 Programming Magnet Operating Instructions
Operator interface to MicroSafe™ gas detection products is via magnetic switches located behind the
transmitter face plate. DO NOT remove the glass lens 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 12 Programming Magnet
A magnetic programming tool (see Figure 12) is used to operate the switches. Switch action is defined as
momentary contact, 3 second hold, and 30-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 30 second hold, the programming magnet is held in place over a switch
location for 30 or more seconds. Three and thirty second hold is used to enter or exit calibration and program
menus while momentary contact is used to make adjustments. The location of “PGM 1” and “PGM 2” are
shown in Figure 13.
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
