1.0 Introduction

1.1 Warnings and Cautions

The TARGET Series gas detectors are designed to detect hazardous atmospheric conditions. An indication of life threatening hazards should be taken very seriously. NEVER ignore an alarm condition.

ARNINGS

OTE

1.2 Unpack

• Any rapid upscale combustible gas reading followed by a declining or erratic reading may indicate a gas

concentration beyond the upper-scale limit. This may indicate a flammable concentration.

• Off-scale readings may indicate a flammable concentration.

• Electromagnetic interference (EMI) signals may cause incorrect operation.

• CSA requirement: Before each day’s usage, instrument sensitivity must be tested on a known concentration of

methane between 25-50% LEL. Accuracy must be within –0 to +20% of the actual concentration applied. Accuracy may be corrected, if necessary, by performing sensor calibration.

• Oxygen deficient conditions can cause lower combustible gas readings than actual concentrations.

• Oxygen enriched conditions can cause higher combustible gas readings than actual concentrations.

• The instrument batteries should only be charged in a non-hazardous location.

• The instrument should only be connected to a computer in a non-hazardous location.

AUTIONS

Any sensor that fails calibration procedures should be replaced and recalibrated immediately. The combustible portion of this instrument has been assessed by CSA for performance. Users may refer to ANSI/ISA

RP12.13 or an equivalent international recommended practice for guidance in the use of combustible gas detection equipment.

TARGET instruments with a CSA logo on the serial number label are approved for Intrinsic Safety when used in Class 1, Division 1, Group A, B, C, D Hazardous Location environments.

• In case of an atmospheric alarm condition, follow your organization’s established procedures for such a situation.

Evacuating the affected area is usually the first course of action, followed by ventilation and re-testing of the environment prior to re-entry.

• Silicone compound vapors may adversely affect the TARGET instrument’s standard combustible sensor causing

lower readings than actual concentrations. If the instrument has been exposed to silicone vapors it is strongly recommended that the instrument be recalibrated prior to its next use. Repeated exposure to silicone compounds will prematurely destroy the standard combustible sensor.

NOTE: The optional MOS combustible sensor is much less susceptible to silicone poisoning, but instrument

calibration should take place on a more frequent schedule.

• The sensor sampling area must be kept clean. Contamination of this area can prevent proper operation of the

sensors.

: Any specifications stated in this manual may change without notice.

Unpack the TARGET Series instrument and examine it for shipping damage. If such damage is observed, notify both ENMET customer service personnel and the commercial carrier involved immediately.

3.4 Alarms

Never ignore an alarm condition!

procedures for such a situation. If the cause of the alarm is an atmospheric condition, evacuating the affected area is usually the first course of action, followed by ventilation and re-testing of the environment prior to re-entry.

If an alarm for any sensor is acknowledged (silenced), the audio alarm reactivates in case of an additional alarm condition for that sensor or any others occur.

In case of an alarm condition, follow your organization’s established

3.4.1 Instantaneous Gas Alarm

The TARGET Series instrument has two levels of instantaneous alarm for each installed sensor. For the oxygen channel, the alarms are for oxygen deficiency and enrichment. For the toxic and combustible sensors, there are low and high alarms. Default alarm values are shown in Section 9. Values in the instrument may be viewed by entering the Operational Menu. See Section 4.2 or 5.2. All instantaneous alarms are latching and continue to activate audio and visual indicators until they are acknowledged by pressing the SELECT button. If an alarm is acknowledged, visual indication continues until the condition clears.

The low level alarm for toxic and combustible gases is identified by a flashing LED and a pulsed audio tone. The audio alarm may be acknowledged and silenced by pressing the SELECT button. If the alarm condition doesn’t clear, the audio alarm will reactivate in 10 minutes.

The high level alarms for toxic and combustible gases is identified by a steady LED and a continuous audio tone. The oxygen alarms act in this same manner. The audio alarm may be acknowledged and silenced by pressing the SELECT button. If the alarm condition doesn’t clear, the audio alarm will reactivate in 5 minutes.

During either instantaneous alarm condition, the display automatically peak holds the highest concentration of the affected sensor until the alarm is acknowledged. If a low level “pulsed” alarm occurs, and is acknowledged, the audio alarm reactivates as a steady tone if the high level alarm level is exceeded.

3.4.2 STEL/TWA Alarms

The STEL and TWA alarms are present for the TOX1 and TOX2 sensors. Default alarm values are shown in Section

9. Values in the instrument may be viewed by entering the Operational Menu. See Section 4.2 or 5.2. A STEL or TWA alarm is identified by a steady LED and continuous audio tone. The status line of the LCD shows

the type of alarm. The audio alarm may be acknowledged and silenced by pressing the SELECT button. If the alarm condition doesn’t clear, the audio alarm will reactivate in 5 minutes.

TARGET Series ENMET Corporation

3.4.3 Over-range and Under-range Alarms

The over-range alarm activates audio and visual alarms. It can occur if the instrument is exposed to a gas concentration higher than its display range. Over-range alarms cannot be acknowledged. An alarm for the Toxic or Oxygen sensors clears once the over-range condition clears. The over-range alarm for the combustible sensor is latching and will not clear until the instrument has been removed from the affected area, turned off and turned on in an environment less than 100 %LEL. Under range conditions can occur if an instrument is auto-zeroed or calibrated in an area with background levels of gas. Under range alarms can be cleared by performing an auto-zero function as described in Section 3.5.1.

The over-range condition is indicated by OVERNG shown in the affected sensor location on the display. Under-range is indicated by UNDRNG.

3.4.4 Low Battery

The TARGET Series instrument has a low battery alarm to provide the user with adequate warning of a low battery condition. The instrument provides a steady tone audio alarm when there is approximately 15 to 30 minutes of battery life left. A low battery warning message is displayed on the status line of the instrument LCD. The audio alarm can be acknowledged by pressing the SELECT button. The audio alarm and backlight reactivate after approximately five minutes. See section 3.2 for battery charging procedure.

3.4.5 Fault

Fault alarms have a steady audio alarm and are displayed on the status line of the LCD. The status line describes the fault condition and appropriate action should be take to resolve the issue. See section 11 for troubleshooting information.

3.5 Pop-Up Menu

The Pop-Up menu is displayed after the one minute instrument warm-up procedure. The instrument beeps several times prior to showing this display. The Pop-Up menu provides the user the ability to perform an auto-zero, check the last date of calibration, change the combustible gas display, set user locations and activate/deactivate the optional internal pump, if installed.

3.5.3 Combustible Gas Display

Combustible gases vary considerably with respect to their flammable nature. Some gases are flammable at lower concentrations than others. The TARGET instrument has ten flammable gases response characteristics programmed in memory. Each gas has a different coefficient (K) that is used to compensate the instrument display:

Table 2: Programmed Flammable Gas Coefficients

Methane Mth K=1.00 Propane Prp K=1.88 Butane Btn K=2.04 Pentane Pnt K=2.30 Hexane Hxn K=2.35 Hydrogen H2 K=1.24 Ethane Eth K=1.54 Benzene Bnz K=2.51 Toluene Tln K=2.47 Xylene Xyl K=2.99

The combustible sensor cannot determine which gas is present. When the combustible gas is unknown, it is recommended to change the display to higher K (coefficient) value gas. Hexane or Xylene may not be the gases present, but using their K value substantially increase, the instrument’s sensitivity to flammable gases.
