Page 22: Operating Instructions
TXP-WTA_Instruction_Manual_(Rev1.3) 6 Operating Instructions 6.1 Using the Magnetic Keypad Each TXP-WTA Sensor Transmitter is supplied with an 83-700N-0000-00 (AL and SS) or 83-700M-0000-00 (Poly) magnetic wand for non-intrusive magnetic keypad operation. Keys are identified as UP, DOWN, NEXT and EDIT and function similar to touch keys except a “swiping” motion of the magnet is used instead of pressing a key. - Page 23 TXP-WTA_Instruction_Manual_(Rev1.3) CAL Mode – Routine Calibrations NOTE: Calibration is the most important function for ensuring correct gas readings at the TXP-WTA Sensor Transmitter. The CAL MODE (flow chart shown in Figure 5-3) is designed to make calibration quick, easy and error free. A successful ZERO and SPAN calibration requires only four keystrokes.
- Page 24 TXP-WTA_Instruction_Manual_(Rev1.3) Use the following step-by-step procedure to perform ZERO and SPAN calibrations. NOTE: During TXP-WTA Sensor Transmitter calibrations, alarms are inhibited and “CAL MODE” is displayed on the controller. A gas reading is usually considered “STABLE” when there is no change in the reading for minimum of 30 seconds. 1.

NOTE: If the cable is larger than 6mm diameter (1/4 inch), be aware of sideways tension on the connection. Thick cables have large bending radii and sideways force on the connector can cause a poor connection The polarity of these antennas is the same as the main axis, and they are normally installed vertically. -

TXP-WTA_Instruction_Manual_(Rev1.3) Figure 10-2 – Dipole Antenna Installation Diagram 10.1.2 Yagi Antennas NOTE: Care needs to be taken to ensure the Yagi is aligned correctly to achieve optimum performance. If a Yagi has drainage holes in the dipole element, do not mount with the drain hole up. It can fill with water and cause a negative impact on radio effectiveness. -
Page 46: Mounting Near Other Antennas
TXP-WTA_Instruction_Manual_(Rev1.3) 10.1.3 Mounting Near Other Antennas NOTE: Avoid mounting your network’s antenna near any other antenna even when the other antenna is transmitting on a different radio band. High RF energy of the transmission from a close antenna can deafen a receiver. This is a common cause of problems with wireless systems. -
Page 47: Antenna Grounding
TXP-WTA_Instruction_Manual_(Rev1.3) It is very difficult to protect against direct lightning strikes but the probability of a direct strike at any one location is very small. Unfortunately, power line surges and electromagnetic energy in the air can induce high voltage surges from lightning activity several miles away. -
