The sensor screws into one hub of the enclosure and plugs into the bottom electronics card via a six pin connector. Cabling to the controller connects to a three pin spring loaded terminal strip. 7.5.2 TROUBLE ANALYSIS Electrical adjustment, or replacement of the sensor will be necessary under the following conditions: • Controller displays the following error messages: CHK BRIDGE VOLT SENSOR FAILURE LOW SENSITIVITY • False readings or alarms are received due to sensor inaccuracy. Warning: : Dur

Each alarm level can be programmed to be either non-Latching or Latching and can also be programmed to activate either when the input level is GREATER THAN the user adjusted alarm level or LESS THAN the user adjusted alarm level. When the Model 4011 is used as a 4-20mA signal loop controller a third alarm is provided which detects loop current being less than 3mA. The outputs of the three Alarms are SPDT relays with contacts rating of 10A at 28VDC or 120VAC and are independently fused at 5A. Th

Sentry system two-way communication between the sensors and the controller results in the capability to perform one-person calibration and diagnostic checks from the controller. The user-friendly front panel includes a large display of the gas concentration and sensor number. Various scan modes are available to meet the user’s specific monitoring needs. A separate 2-line alphanumeric display provides more detailed information including sensor data, error messages and menu prompting for calibrati

Available as single channel monitors or part of multipoint alarm system The Model 2050 Ammonia and Model 2060 Refrigerant/ Halocarbon Gas Monitors are continuous duty, low cost stationary monitors for detection of high levels (50-500 PPM) of ammonia and halocarbon refrigerant gases. These monitors are primarily used in and around freezers, refrigerators, and compressor rooms to warn of leaks and dangerous levels of these gases. An alarm is activated when the concentration of gas exceeds the us

Personnel injury and costly business interruptions are also likely. Factory Mutual requires electro-optical flame detectors in the semiconductor wet benches to monitor for fire. These flame detectors must be suitable for the hostile chemicals used in the etching process (such as hydrofluoric, sulfuric, and hydrochloric acids). Furthermore, they must be tested and approved for fire response to FR polypropylene now used in the construction of wet benches as well as other fuels such as isopropyl al

These options aid in providing a system designed to meet the specific needs of the user. CALIBRATORS 1250-00 Calibration Gas Delivery System (High Capacity) The 1250-00 Calibrator Kit is used to deliver calibration gas for combustible gases and a wide variety of toxic gases including Hydrogen Sulfide, Chlorine, Sulfur Dioxide, Nitric Oxide, Nitrogen Dioxide and others. The 1250 Calibrator Kit consists of a regulator, calibration adapter, carrying case and tubing. The calibration gas cylinders (S

A red LED (light-emitting diode) and audible alarm activate when the concentration of gas exceeds the factory- set (and user-adjustable) level. A green LED indicator on the monitor shows that power is connected and it is a safe condition. The standard configuration has a buzzer and normally operating open relay, a fail-safe normally operating closed relay is field selectable. All the electronic circuitry needed to operate the monitor, except the DC input power, is contained in a compact unit. It
