Page 5: General Description
The LCD of the SEC 3100 displays the gas concentration and sensor status. The SEC 3100 has one (1) “Alarm” LED and one (1) “Status” LED. The SEC 3100 also has three (3) magnetic switches located around the circumference of the unit. - Page 6 Wire insulation should be temperature rated for greater than or equal to 70°C. There are 2 earth screws on the SEC 3100. One is on the outside of the enclosure and the other is located on the inside of the enclosure. Both are marked with earth ground symbols and green screws.
- Page 7 Warm-up When power is applied to the SEC 3100, it enters a one (1) minute warm-up mode. The output current will be 0.8 mA during the warmup time period. At the end of the warm-up period with no faults present, the SEC 3100 automatically enters the normal operating mode (4.0 mA with no gas present).

Hard Fault or Unit Zero with gas IV. MAGNETIC SWITCH OPERATION The SEC 3100 has three (3) magnetic switch pickups on the Display PCB. The picture below shows the location of the magnetic switches labeled UP, DOWN and ENTER. Placing a magnet in close proximity to one of the switches will cause the following operations to occur. - Page 9 Switch Operation ENTER Enter Menu Mode, Selects a menu to Enter Moves up through Menu selections DOWN Moves down through Menu selections For further details on gas sensor calibration refer to the appropriate SEC sensor instruction manual. The LCD contrast potentiometer, (POT1) is located under the protective faceplate shown above on the front side (LCD side) of PCB to the left of the LCD.
