Page 9: Introduction
1.0 INTRODUCTION General The Chloralert™ Plus multifunction gas-leak detector is designed to be used for the detection and monitoring of Chlorine (Cl ) and Sulfur Dioxide (SO ) in ambient air. It also activates audio and visual alarms in the event that the concentration of these gases exceeds programmable preset levels. -

Page 19: Functional Description
3.0 FUNCTIONAL DESCRIPTION General The 17CA3000 Chloralert Plus normally consists of two distinct elements, the sensor/transmitter and the receiver. The sensor/transmitter is located near potential sources of gas leaks or emissions while the receiver is located remotely in a control room, although in some instances, they may both be located at the same site. Both elements of the device have inputs and outputs. -
Page 20: Outputs
3.2.1.3 Outputs The output of the sensor/transmitter is wired directly to a terminal block in the receiver so care should be taken that the sensor is correctly connected to the receiver (refer to section 2.4). If the sensor/transmitter is connected incorrectly, no damage will occur but the LED indicator on the sensor/transmitter will not light and the LCD display on the receiver will indicate “BAD ID”. -
Page 21: Receiver Outputs
3.2.2.3 Receiver Outputs The outputs of the receiver fall into two categories • Analog - gas concentration data as a linear current output • Digital - relay contact-closure 3.2.2.3.1 Analog Outputs (AO) An optional 4-20 mA or 0-20 mA analog output linearly proportional to sensed gas concentration is available on terminal block TB1 for each sensor channel. -
Page 22: Operating Modes
ALARM DATA LETTER SETUP ENTER Figure 3-1 Chloralert™ Plus Keypad 3.2.2.5 Operating Modes The following four modes of operation may be selected: • RUN - displays concentration data • SETUP - setup menu • ALARMS - active alarm/events queue • DATA - historical alarm/events queue When the power is first applied, the unit activates in the RUN mode. -
Page 23: Display Modes
3.2.2.7 Display Modes The receiver has a 2 line, 20 character per line LCD display with a character height of 0.19 in. (4.86 mm). The display mode may be selected as either AUTO or MANUAL using the CONFIGURATION menu in the SETUP mode. If an alarm occurs with the display in either mode, the display will change to the 4-channel summary mode automatically. -
Page 24: Watchdog Timer Circuit
3.2.2.8 Watchdog Timer Circuit The “watchdog” circuit is intended to let the operator know that the microprocessor has stopped running. The circuit requires a constant input pulse from the microprocessor that only occurs during proper operation. If the input pulses stop for more than a second, the watchdog circuit will disable all of the relays and cause the display backlight to flash. -

Page 26: Sensor Check
The REPEAT mode continues to cycle through the SELF-TEST sequence until terminated by the operator. When in REPEAT mode, the DISPLAY and KEYPAD self-tests are only performed during the first cycle and are skipped thereafter. In REPEAT mode, the display indicates the number of successful passes through the self-test cycle. If an error occurs while in REPEAT mode, the self-test will stop and the display will flash and indicate the nature of the error and the cycle-number during which the error occurred, as shown below:... -
Page 27: Calibration Mode
CAUTION Initiation of the sensor check feature will temporarily suspend normal gas-monitoring. The sensor check may be run in two modes: • Manual • Auto MANUAL mode requires only that the proper CHANNEL(S) be selected as described above. When the operator is ready to run the check, TEST NOW is selected from the SETUP- CONFIGURE-INSTRUMENT-SENSOR CHECK-MANUAL menu and the checking begins immediately. -
Page 28: Security And Safety
has been successful without having to return to the receiver. The receiver’s display will also provide this information when the operator returns to the receiver once all sensors have been calibrated. This method of calibration permits a single operator to carry out all the calibration by setting the instrument to RUN CALIBRATION and exposing the sensor to the calibration gas without opening the sensor/transmitter or having to make adjustment at either the receiver or the sensor/transmitter. -
Page 29: Level
Each sensor CHANNEL has three alarms modules (ALARM1, ALARM2, AND ALARM3) each of which may be programmed with a number of parameters (refer to section 4.4). Entering the respective SETUP-CONFIGURE-CHANNELS-ALARM menu for each alarm module allows the following alarm module parameter selections: •... -
Page 30: Mode
3.2.2.14.2 Mode There are four alarm concentration-calculation modes available to calculate the gas concentration average: • INST - Instantaneous, generates alarm as soon as gas concentration exceeds concentration alarm level. • STEL - Short Term Exposure Limit, 15 minute time weighted average of measured gas concentration. -

Page 38: Data Entry
The operator interface consists of the following activities: • Awareness of the level of gases being monitored. • The operator must know how to enter, navigate and exit the menus. Entering information consists primarily of selecting an entry but numerical data must be entered for certain menu parameters. -
Page 39: Setup
When power is first applied to the Chloralert™ Plus, it will activate in the RUN mode. The front panel LCD display will indicate OFF on all four channel indicators. To make the unit operational, a sensor channel must be activated by entering appropriate parameters. This is done using the SETUP mode. -

Page 50: Run Self-Test
NOTE If the auto sensor check has been enabled and it is desired to change the start time or interval, the auto sensor check must first be disabled before entering the new parameters. Reselect ENABLE when the new values have been entered. When in AUTO mode, a power failure occurring during SENSOR CHECK will cause the SENSOR CHECK to be terminated. -

For a more detailed discussion of the self-test, refer to section 3.2.2.9 of this instruction bulletin. WARNING All alarm operation is temporarily totally disabled during this test. 4.4.2.1.11 Enter Configuration Code This menu requires the entry of the unit’s CONFIGURATION CODE. This code represents the hardware configuration of the customer’s unit and includes the appropriate codes for any optional features. -

Four possible status indications may occur: • ABSENT • • CHARGING • FULLY CHARGED BATTERY STATUS FULLY CHARGED Information for this status is updated at several times: • At power-up • When exiting SETUP • Hourly In normal AC-powered operation, the battery is constantly under charge. Every hour, on the hour, the unit performs a test of the battery, under load, to determine its condition and then writes the result to the battery status display. -
Page 53: Sensor Type
Up to a maximum of 10 characters may be assigned to represent the unit. This is most useful if the unit has the optional datalink serial communications capability, allowing the unit to be remotely identified over the datalink. If entered, the tagname is shown on the top line of the display when the display is in single-channel mode (refer to section 3.2.2.7). -
