Lipolelo Tsa Temoso
The RKI Instruments, Inc. T2A Toxic Gas Monitor is Class I Division 1 Certified. The assembly is able to maintain its certification at all times while in the field, simply by using the non-intrusive calibration method which requires the use of an RKI-distributed magnet. However, if the Moore lid is removed, for whatever reason, the T2A’s certification is no longer valid. To avoid invalidating the certification, complete all wiring configurations BEFORE putting the T2A in the field. Once in the field, always use the RKI-distributed magnet to ensure non-intrusive calibration. Strong magnetic fields may interfere with the non-intrusive magnetic switches. A strong magnetic field may momentarily active a switch, or permanently disable the switch to the “on” or “off” position. Do not cover the hole in the calibration cup, as this will cause the calibration to be inaccurate.

The RKI Instruments, Inc. T2A Explosion-Proof Ambient Air Hazardous Gas Detector is designed to detect a wide range of toxic gases in potentially hazardous environments. This product’s enclosure is QPS certified as Class I, Division 1, Groups B, C, and D and rated for Class I, Zone 1, Group IIB. The T2A features non-intrusive magnetic switches that allow for complete system configuration, regular calibration, and product maintenance to be performed in the field, without opening the enclosure and breaking the seal of the enclosure, thereby compromising the explosion-proof rating of the device. Non-intrusive interface with the T2A is made possible by use of the magnetic tool included in the purchase of the device. The T2A display screen will always show the present concentration of gas being detected by the sensor assembly.
This document is an operation manual containing diagrams and step-by-step instructions for the proper and safe installation, start-up, configuration and settings, normal operation, and product maintenance of the T2A.

When the controller relays are triggered, alarm devices will perform as intended, initiating emergency procedures as if a harmful or toxic gas was actually present. To prevent this from occurring, set the controller to calibration mode before performing the alarm test. Calibration mode allows data transmission without relay activation.

Ho tima Sensor (20.9% bakeng sa O2)
The first step of calibration is zeroing (20.9% for O2). The zeroing (20.9% for O2) process MUST be performed in known clean air, with no contaminants or hazardous gasses present. If air quality cannot be guaranteed, a cylinder of zero air will be required to properly zero the sensor. 1. While the product is in normal operating mode, press the MENU button to activate the
Operation Settings menu.
2. Tobetsa konopo ea ADD ho qala ts'ebetso ea zero le ho fetela skrineng se hloekileng sa netefatso ea moea.
3. If the sensor is in clean air, press the ADD button to select “Yes” and continue to Step 5. 4. If the sensor is not in clear air, perform the following:
a. If a rain guard is installed, unscrew and remove it from the assembly. b. Install the calibration cup to the T2A’s sensor housing. c. Screw the regulator into the zero air calibration cylinder. d. Use the sample tubing ho hokahanya selaolo le senoelo sa calibration. e. Fetola konopo ea regulator ho ea ka nqa ea ho otlo ho bula regulator. f. Lumella khase ho phalla motsotso o le mong. g.

NOTE: HCl – It is recommended that the HCl version only be calibrated using Auto Cal, but Manual Cal can be used if desired.
You should ONLY calibrate the sensor after completing the zero process. 1. For EtO calibration gas: Connect the tubing to the regulator, turn the regulator on, and allow
gas to flow for 1 minute before proceeding. For HCl calibration gas: Connect the tubing to the regulator, turn the regulator on, and allow gas to flow for 10 minutes before proceeding. 2. If you followed the instructions in Zeroing the Sensor (20.9% for O2), the screen below is displayed. If you are accessing Manual Cal from Normal Operating Mode, press MENU twice.
