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.

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.

Page 10

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.

If the pump is off, the bottom line of the display says “Set Pump ON”. If the pump is on, the bottom line of the display says “Set Pump Off”.

OTE

The Pump feature is only displayed in the Pop-Up menu if the instrument is supplied with the optional internal

sampling pump.

Attach the sampling shield supplied with the instrument, to the bottom of the instrument in the same manner as the calibration shield, see Figure 8. The calibration shield has a orange label. The sampling shield has an yellow label.

Attach the supplied 20 foot sampling hose or the optional 2 foot sampling wand to the hydrophobic filter on the back of the shield.

Sensor response time, if the tubing is 20 feet long, allow at least 10 seconds for the test sample to make it through the tubing. The sensor response time is typically 30 – 60 seconds to achieve 90% of the final reading, depending on the specific sensor and the gas being detected. Therefore, the total 'system' response time for an instrument using the internal sampling pump and 20 feet of hose is approximately 40-70 seconds to achieve 90% of the final reading.

OTE

The sampling shield and sampling hose or wand must be firmly and correctly attached to the TARGET

instrument for proper remote sampling operation.

The instrument monitors the sample pump operation and provides an audible alarm and visual indication on the status line of the display, in the event of a low flow condition.

OTE

The sampling shield and sampling hose or wand must be removed from the TARGET instrument for diffusion

operation.

For instruments with internal sampling pumps, a calibration procedure is required whenever a pump is replaced or when calibration is performed on the instrument sensors.

It is also recommended to perform pump calibration if any abnormal pump operation is observed. Pump calibration is performed in the Advanced Maintenance Menu. See section 6.4.8 for pump calibration instructions.

6.0 Maintenance Operations

6.1 Recommendations

Instrument calibration should be performed at least once every three months. Field tests using gas concentrations above alarm level should be performed at least monthly or prior to each use for

seldom used instruments. For frequently used instruments, field tests should be performed bimonthly to weekly. A field test consists of applying field test or calibration gas and confirming appropriate gas sensor response.

Instruments with sensors installed in the BRH location should remain on charge when not in use to stabilize sensor response.

6.2 Standard Maintenance Menu

The Standard Maintenance menu provides the quickest and simplest access to the most common maintenance procedure, instrument calibration.

To enter the Standard Maintenance menu, press the MENU button repeatedly from the main gas display or Operation menu. Move the asterisk until it is next to the Maintenance Menu line. Press the SELECT button to move to the password entry screen. The password is set to 1270 from the factory. Note the cursor under the first digit. Use the MENU button to increment the digit and the SELECT key to move the cursor to the next digit. Press SELECT when the password has been entered. If proper password is not entered, INVALID PASSWORD is displayed and the instrument returns to Operation menu.

6.3 Calibration

6.3.1 Calibration Menu

Calibration is the process of aligning the instrument electronics to the installed sensors, making the instrument read accurately. It consists of a zero reading which tells the instrument what it should read in fresh air, and a span reading which tells the instrument what it should read in the presence of its target gas.

Instruments configured for the combination of gases CO/H2S/O2/Mth, sensors may be calibrated all at once with multi-component gas. All other configurations, calibration must be performed for each sensor individually. See section 7.0 for ENMET part numbers of available calibration gas.

To initiate a calibration procedure, move the asterisk to the appropriate location using the MENU button. Press the SELECT button to choose the calibration procedure. If N/A appears next to a sensor then that sensor is not installed in the instrument and calibration is not possible.

OTE

: The calibration procedure may be aborted by pressing the MENU button anytime during the process.

OTE

: If a sensor is installed in the BRH location, the instrument display may show BRH, HS+, CO+, Tol, or similar.

It will always appear above the O2/CO/H2S/Mth combination calibration. The instrument must be on charge over night prior to calibration or field test.

6.3.3 Applying Span Gas

Attach the calibration adapter to the cylinder of span gas and calibration shield. See figure 8.

AUTION

: Some gas require that the Target Sampling Shield and flow demand regulator be used for calibration. See

Section 8.0, Table 3 and 4.

BRH L

OCATION

 Place instrument on charge over night.  The BRH sensor should be calibrated before any others. If the BRH sensor is installed in the TARGET, it will

become contaminated if exposed to the combination or test gas and must be calibrated separately.

 If the BRH sensor is being calibrated with the 04834-002 calibration fixture, fill the humidifier bowl approximately

1/3 full with clean, tap water. The tube should NOT go under the water line. No bubbles should be visible when gas is flowing. See figure 8.

OTE

: The arrow on the humidifier bowl points in the opposite direction of airflow.

 If the BRH sensor is being calibrated with the 04834-005 calibration fixture, fill the humidifier bowl to level

indicated. Use the storage case to support the humidifier while in use. See figure 8.

OTE

: The arrow on the humidifier bowl points in the same direction of airflow. 04834-005 calibration fixture

supplied starting November 2002.

 Failure to follow both of the BRH steps will cause an inaccurate calibration.

OR ALL OTHER SENSORS INSTALLED

 Use the reactive gases calibration adapter which does not have a humidifier bowl. For CO, O2, Methane sensor

calibration these sensors may be calibrated simultaneously or individually using the combination calibration gas and reactive gases calibration adapter. See figure 8.

OTE

: When calibrating CO, O2 and CH4, with individual gas cylinders, the BRH calibration adapter should be used.

 Failure to do so will cause an inaccurate calibration.

SPAN gas concentrations are not adjustable in this calibration procedure. SPAN gas concentrations are, by design, the concentrations available with ENMET calibration kits. See Section 8.0 for the default concentrations. If other concentrations are to be used for calibration, the calibration procedure in the Advanced Maintenance menu must be followed.

OTE

: If the span gas value has been previously changed in the Advanced Maintenance menu, that change is

carried over to this procedure.

∆ These gases require the Sampling Shield p/n 04836-000 to be in place and pump activated for

accurate detection and calibration.

Sensor response time with internal pump, if the tubing is 20 feet long, allow at least 10 seconds for the test sample to make it through the tubing. The sensor response time is typically 30 – 60 seconds to achieve 90% of the final reading, depending on the specific sensor and the gas being detected. Therefore, the total 'system' response time for an instrument using the internal sampling pump and 20 feet of hose is approximately 40-70 seconds to achieve 90% of the final reading.
