SERVICE MEMO Precautions for Handling Electrostatic Sensitive Devices With the trend toward increasingly widespread use of microprocessors and a wide variety of other electrostatic sensitive semiconductor devices, the need for careful handling of equipment containing these devices deserves more attention than it has received in the past. * Electrostatic damage can occur in several ways. The most familiar is by physical contact.

DET-TRONICS INSTRUCTIONS ® EAGLE 2000™ Hazard Event Monitoring System Section I System Overview NOTE This manual covers the basic operation of the communication module, digital communication unit, gateway, network extender and relay module. It will not cover any specific detector, host device or Operator Interface Station. Refer to the appropriate instruction manual for complete information relating to these devices.

sive calibration. Unlike the communication module, the DCU allows the operator to view three status indicating LEDs through a viewing window on the enclosure cover. NETWORK OPERATION DURING A FAULT CONDITION The Eagle system utilizes a unique method for detecting an open or short in the communication network wiring. This state-of-the-art feature minimizes the possibility of a communication breakdown in the event of a wiring fault in the communication loop and can also serve as an aid in troubleshooting.
Section II EA2300CM Communication Module Multiple Wiring Faults In the event of multiple wiring faults, the nodes between the faults will continue to function, but the faults will prevent them from communicating with the main gateway (Figure 4). In this example, nodes 1 to 4 communicate using one gateway port (path A) and nodes 7 and 8 use the other gateway port (path B). Nodes 5 and 6 are unable to report to the gateway because they are isolated by the two wiring faults.
The red LED indicates the various steps of the calibration process. When the calibration begins, the red LED flashes at a 1 Hz rate. When the zero part of the calibration is completed, the LED is on steady. The span gas is then applied to the sensor, the sensor input increases, and the LED flashes at a 1 Hz rate. When the span part of the calibration is completed, the LED is again on steady.
OUTPUTS Calibration Log A 5 ampere SPDT relay is provided. When the communication module is used with a U8700 or U8800, the relay output is used to reset the transmitter. The relay is actuated for 1 second when a “reset sensor” signal is sent to the communication module by the gateway in response to a request from the host. A log is kept for each calibration. This information can be used by the operator to evaluate the remaining life of a sensor.

It is designed to meet CENELEC requirements for EEx d IIC T5 hazardous locations, and is IP66 and NEMA 4 rated. The removable cover is furnished with a window to allow the operator to view the three status indicator LEDs on the communication module PC board.
Section IV EA2100CG Communication Gateway HUMIDITY RANGE— 0 to 90% RH, non-condensing. SHIPPING WEIGHT (Approximate)— 2.6 lb (1.2 kg). APPLICATION DIMENSIONS— See Figure 9. The gateway provides the communication link between a Det-Tronics addressable detector and the host device. Registers in the gateway are used for passing information between the host and communication modules. The gateway communicates with the host device through a serial interface port (RS232 or RS422) using Modbus protocol.
AUXILIARY GATEWAY Digital Display Auxiliary gateways are used to connect additional host devices to the loop for data acquisition purposes. Additional host devices are not able to modify configuration information for the devices on the loop. The digital display is a three digit “seven segment” display. During normal operating conditions, the display indicates “000.

HOST MULTIPLEXER In the second form of diagnostics, the gateway provides a watchdog timer for each configured device on the loop. Each time the device reports to the gateway, the timer accumulator is reset to zero and the timer starts over.
GENERAL INFORMATION HUMIDITY— 0 to 95% RH at 70°C. SYSTEM CAPACITY WIRING— The communication network requires 22 AWG level 4 shielded twisted pair wire. Other wiring should be 18 AWG minimum. Eagle system technology allows the main gateway to support a communication loop consisting of up to 60 detection nodes, with up to 2000 meters of connecting wiring.

All external wiring is connected to screw terminal connectors on the terminal wiring board that is factory mounted inside the enclosure. The electronic module is mounted inside the enclosure above the terminal wiring board and is connected to the terminal wiring board with a ribbon cable. ADDRESSABILITY Relay module identification is accomplished by setting rocker switches on an eight position DIP switch located on the electronic module. Valid addresses are from 5 to 110.
NODE GATEWAY NODE NODE NODE NODE “breathing.” Moisture in the air can condense at the base of vertical conduit runs and equipment enclosures, and can build up over a period of time. This can be detrimental to electronic devices. To eliminate this condition, explosion-proof drains and breathers should be installed to automatically bleed off accumulated water. Always observe the requirements of local codes. NOTE Any deviation from the recommended wiring practices can compromise system operation.
Temperature. Resistance increases as operating temperature rises. Calculate resistance at a worst case temperature of 75˚C. See Table 5. Example B: How many combustible gas DCUs can operate at the end of a 1000 foot length of 14 AWG wire? Type of device. Refer to the “Specifications” section for current ratings. Always consider the maximum (not nominal) current draw of each device. This typically occurs at startup and/or when relays are energized.

Whenever practical, detectors should be placed where they are easily accessible for calibration. Gas sensors should be pointing down to minimize the accumulation of contaminants on the filter and to ensure proper operation. Junction boxes should be electrically connected to earth ground.

CALIBRATION Section VIII System Startup To ensure optimum protection, calibration must be performed on a regularly scheduled basis. Since each application is different, the length of time between regularly scheduled recalibrations can vary from one installation to the next. In general, the more frequently a system is checked, the greater the reliability. STARTUP PROCEDURE 1. Output loads that are controlled by the system should be secured (remove power from all output devices) to prevent actuation.
If the calibration is not completed within 12 minutes, the previous calibration values are restored and the calibration is logged as aborted. The calibrate LED flashes at a 4 Hz rate, the calibrate bit in the status word is reset and the calibration fault bit is set. CALIBRATION ALGORITHM A (Type Codes 1, 2, 3, 4) for Gas Detectors Normal Calibration 1. Activate the reed switch or input 1 on the communication module (See Figure 29).

CAUTION The O-ring should be lubricated with a silicone free polyalphaolefin grease. The use of other lubricants is not recommended, since they can adversely affect the performance of some sensors. Under no circumstances should a lubricant or compound containing silicone be used on systems using catalytic type combustible gas sensors.
