FP-700 Instruction Manual Rev. 3.0 Page 12 of 40
Initial operational tests are complete. Detcon FP-700 combustible gas sensors are factory calibrated prior to
shipment, and should not require significant adjustment on start up. However, it is recommended that a
complete calibration test and adjustment be performed 16 to 24 hours after power-up. Refer to zero and span
calibration instructions in Section 3.4.Operation
3. Operation
3.1 Programming Magnet Operating Instructions
The Operator Interface of the Model 700 Series gas sensors is accomplished via two internal magnetic
switches located to either side of the LED display (see Figure 13). The two switches, labeled “PGM1” and
“PGM2”, allow for complete calibration and configuration and thereby eliminate the need for area de-
classification or the use of hot permits.
Figure 12 Magnetic Programming Tool
The magnetic programming tool (Figure 12) 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. For 3-second hold, the programming magnet is held in place over the switch location
for three seconds. For 10-second hold, the programming magnet is held in place over the switch location for
10 seconds. 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.
The location of “PGM1” and “PGM2” are shown in Figure 13.
