3.6.4 Programming Magnet Operating Instructions

perator 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, there-

by eliminating the need for area de-classification or the use of hot permits.

A magnetic programming tool (see figure 5) is used to operate the switches. Switch action is defined as momentary con-

tact, 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 6.

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.
