3. Operation
3.1 Programming Magnet Operating Instructions
The Operator Interface of the OLCT 700/710 gas detectors is accomplished via two internal magnetic
switches located to either side of the LED display (see Figure 10). The two switches, labeled “PGM1” and
“PGM2”, allow for complete calibration and configuration, thereby eliminating the need for area de-
classification or the use of hot permits.
Figure 9: Magnetic Programming Tool
The magnetic programming tool (Figure 9) is used to operate the magnetic switches. Switch action is
defined as momentary contact, 3-second hold, and 10-second hold (hold times are defined as the time from
the point when the arrow prompt ◄ appears). For momentary contact use, the programming magnet is
briefly held over a switch location. The 3 and 10 second holds are generally used to enter
calibration/program menus and save new data. The momentary contact is generally used to move between
menu items and to modify set-point values. Arrows (◄ and ►) are used on the LED display to indicate
when the magnetic switches are activated.

NOTE : While in the Program Mode, if there is no magnetic switch interaction after 4
consecutive menu scrolls, the detector will automatically revert to normal operating condition.
While changing values inside menu items,
if there is no magnet activity after 3-4 seconds
the detector will revert to the menu scroll (exception to this is with “Signal Output Check”
mode).
