GSM-60 ENMET

1.0 Introduction

The GSM-60 is a sample draw monitoring instrument that measures and detects certain toxic hazards gases. The GSM-60 was designed primarily for monitoring one area with a single sampling hose, either for an individual gas or multiple gases. The instrument has one sampling pump and one flow sensor. The instrument is available with up to 4 internal sensors. Available sensors include, but are not, limited to carbon monoxide (CO), carbon dioxide (CO

2

), Hydrocarbons (HC) and variations in the oxygen (O

2

) content. The sensors can be used alone or up to four sensors can be used together. Some applications require monitoring of more than one area. If two sampling hoses are connected to one GSM-60 the flow sensor can only detect a total flow fault condition. For example, a pump failure or both sampling hoses being blocked. The system cannot detect a flow fault if only one of the two sampling hoses is blocked.

Flowmeters should be installed in both sampling lines to provide a visual indication of proper flow. In the instrument, a 24 V DC sampling pump pass air over each sensor and the resulting electrical outputs are used to evaluate the air for the target gases.

The GSM-60 is a highly adaptable instrument. Some adaptations require an addendum be added to the manual to facilitate use of the instruments with these adaptations. If addendum is needed, see page(s) between sections replacement part numbers and warranty.

Some features of the instruments are as follows:

 continuous monitoring of the sample air

 continuous LCD display of gas and vapor concentrations

 menu driven operational and maintenance controls

 menu driven calibration procedure

 audio and visual alarms indicate unsafe conditions



 alarm relay contacts available on terminals

 a fault relay and visual fault alarm

 low air flow fault indication and display

 alarm acknowledgement capability including audio defeat mA outputs for each target gas

Hydrocarbons (HC) are limited to gases with an ionization potential of 10.6 eV or less. See Appendix B for a list of gases and IPs.

If you have a question involving the location of a unit or sensor, please contact your distributor or ENMET personnel. A technician will analyze the question and recommend a location.

3.3.2 Relay Contacts

Relay contacts are available for each alarm; these are SPDT, rated at 10Amp at 110V AC , and may be latching or non-latching as required by the application.

They are accessed on the terminals next to each relay see Figure 2 & 2A . The contact positions are noted on the circuit board next to each terminal.

Relays may also be configured as failsafe or non-failsafe. The default alarm relay configuration is for latching mode, and failsafe. They may be reconfigured in the maintenance menu. See section 5.3.5 & 5.3.6

The PC Board is labeled for the relays in their un-energized state. If the relay is configured for failsafe, then this is also the alarm condition state. Non-failsafe configured relays in the alarm state, are the reverse of the PC board labeling. Note that the

Fault(FLT) relay cannot be set to operate in a Non-Failsafe mode. Please see the Table 1 on page 10:

In addition, there is a fault relay, which changes state whenever the instrument is in a fault condition. The contact positions are noted on the circuit board next to each terminal. See Figure 2A.

The coil of this relay is energized when the instrument is in the non-fault state; the contact conditions given on the circuit board next to the terminal, are for the non-energized state, which is identical to the fault state.

These relay contacts can be used to operate auxiliary alarms or other functions. It is recommended that power for auxiliary equipment be supplied from an independent power source, separate from the GSM-60 . Place a hole in the enclosure for a wire exit, and use appropriate cable fittings. Be sure to note the location and depth of hardware inside the enclosure.

3.3.3 Optional 4-20mA Outputs

Isolated 4-20 mA outputs are available for data logging or other purposes. An output is supplied for each sensor supplied in an instrument, and can be added when a sensor is added in the field. These outputs are available on the Connector 1 for channels 1

& 2 and Connector 2 for channels 3 & 4.

4mA corresponds to a sensor reading at the bottom of the instrument range and 20mA corresponds to a full-scale reading.

Standard ranges are shown in Table 2 .

3.4 Installation Verification

All instruments are calibrated at the factory. You may, if a calibration kit is available, calibrate the all gas channels of the instrument 24 hours after installation to verify proper installation and instrument operation. See Section 5.0

, Maintenance, for calibration instructions. Calibration is also recommended after the first month of operation. Subsequent calibrations should be performed every 3 months. The dew point sensor cannot be calibrated in the field.

The alarm set points can be changed within limits; see the maintenance section of this manual for the procedure.

 If the CO concentration increases above that of the alarm set point, the associated red LED is lit, the associated relay changes state, and the audio alarm is activated.

 If the dew point increases above that of the alarm set point, the associated red LED is lit, the associated relay changes state, and the audio alarm is activated.

 If the oxygen content of the sample air decreases below the deficiency alarm set point, the associated red LED is lit, the associated relay changes state, and the audio alarm is activated.

 If the oxygen content of the sample air exceeds that of the abundance alarm set point, the associated red LED is lit, the audio alarm is activated, and both the oxygen alarm relay and the oxygen high alarm relay change state.

 The HC sensor can only detect and alarm to hydrocarbons with an Ionization Potential of less than 10.6 eV. See Appendix

B .



The HC sensor is broad range in nature and is unable to differentiate between different hydrocarbons.

 The Alarm 1 differential value is the delay of the GSM-60 staying in alarm condition until after the measured reading has returned past the alarm point by the differential value. Example : If the alarm set point is

Λ

10 and the differential is 2, the

GSM-60 will go into alarm at 10 and stay in alarm until the reading has dropped below 8.

GSM-60 ENMET

4.3 Alarm Latching or Differential Settings

An instrument is shipped with the alarms in the latching mode. The alarms may be independently configured in the non-latching mode or differential setting by use of the maintenance menu.

See Section 5.3.3

, for setting alarm 1 and alarm 2.

Standard Setting

 I N THE LATCHING MODE : at the cessation of the condition which causes an alarm, the alarm indications do not cease, and the alarm relay contacts do not revert to the non-alarm state, until the AUDIO DEFEAT / ALARM ACKNOWLEDGE switch is pressed.

An alarm can also be acknowledged by pressing the switch during the alarm condition; then at the cessation of the alarm condition, alarm indications cease and alarm relays revert to the non-alarm state. After an alarm is acknowledged, alarms in the latching configuration are re-armed to latch at the next alarm condition.

 I N THE NON LATCHING MODE : at the cessation of the condition that causes an alarm, the alarm indications automatically cease, and the alarm relay contacts revert to the non-alarm state.

Differential Setting

 The Alarm 1 differential value is the delay of the GSM-60 staying in alarm condition until after the measured reading has returned past the alarm point by the differential value. Example : If the alarm point is

Λ

10 and the differential is 2, the GSM-

60 will go into alarm at 10 and stay in alarm until the reading has dropped below 8.

4.4 Audio Defeat

Pressing the AUDIO DEFEAT / ALARM ACKNOWLEDGE switch during an alarm temporarily silences the audio alarm. Relays and alarm LEDs continue to function, in the alarm state, during an alarm condition. If the alarm condition persists, the audio alarm will

“chirp” every 20 seconds.



If after 15 minutes the alarm condition continues the audio alarm will reactivate at full intensity.

 If any other alarm condition occurs while the audio alarm has been silenced it will force the audio alarm to reactivate immediately.

4.5 Display

In clean air a display is shown in Figure 4 .

This position of the display is termed the " operational display ". As explained below, the display can be used to view other information by using the OPTION and SELECT switches.

Concentrations of CO and CO2 are given in PPM (parts per million parts of air). Dew point is given in degrees Fahrenheit at 55

PSIG ; this can be changed to degrees Centigrade by pressing the SELECT switch . Oxygen concentration is given in percent by volume.

When sample flow is reduced below a limit, the bottom line of the display flashes “Low Flow Alarm”.

GSM-60 ENMET

4.6 Operational Menu

The operational menu allows the user to:

 View alarm set point concentration values

 View alarm ascending/descending trigger, latching and delay configurations

 Enter the maintenance menu with the proper Password.

The operational menu is accessed with the OPTION and SELECT switches. The operational menu flow chart is shown in Figure 5 ,

 Pressing the OPTION switch is indicated with a " O "

 Pressing the SELECT switch is indicated with a " S ".

If the instrument is left at any location in the operational or maintenance menus, other than the operational display, with no action taken for a period of 45 seconds, it returns to the operational display.

4.7 Fault Indications

4.7.1 Low Flow Indication

A flow sensor is used to furnish a low flow indication. When the sample air pressure drops below preset levels, the fault light and audio alarm are activated, and the display flashes “Low Flow Alarm”. If two sampling hoses are connected to one GSM-

60 , the flow sensor can only detect a total flow fault condition. For example: a pump failure or both sampling hoses being blocked. The system cannot detect a flow fault if only one of the two sampling hoses is blocked.

4.7.2 Other Fault Indications

Other fault indications are associated with sensor zero and calibration activities, and are described in the maintenance Section

5.0

of this manual.

4.8 Hydrocarbon Sensor Response

If a Hydrocarbon (HC) sensor is supplied with the GSM-60 instrument, it designed to detect hydrocarbon gases and vapors with an ionization potential (IP) of 10.6 eV or less. Hydrocarbons with an IP of greater than 10.6 eV will NOT be detected. Please see

Appendix B for a list of common gases and vapors and their respective IP rating.

Unless otherwise noted Isobutylene is used as a calibration and reference gas.

GSM-60

5.0 Maintenance

ENMET

The GSM-60 requires periodic sensor calibration and replacement. Calibration of toxic gas and oxygen sensor should be performed immediately following installation, one month after installation and every 3 months thereafter. HC sensor should be calibrated monthly. Oxygen and CO sensor have an estimated lifetime of 1 – 2 years. The CO2 sensor has an estimated lifetime of 3 years.

Other sensors vary. Sensors should be replaced when they will not calibrate or shortly before the end of the estimated lifetime.

5.1 Cleaning Instructions

C AUTION : Never spray a cleaning solution on the surfaces of the GSM-60 devices.

Clean the exterior of the GSM-60 enclosures with a mild soap solution on a clean, damp cloth. Do not soak the cloth with solution so that moisture drips onto, or lingers on, external surfaces.

Under no circumstances should organic solvents such as paint thinner be used to clean instrument surfaces.

(Gas Channels)

Calibration is the process of setting the instrument up to read accurately when exposed to a target gas. This is a two-step process.

A Low Calibration sets clean air reference point and the High Calibration function sets the sensitivity of the instrument.

Calibration equipment is available from ENMET to calibrate the GSM-60 . A list of needed material is in Section 7.0. A calibration adapter will have a fitting for the gas cylinder on one side, and a quick-disconnect to attach to the instrument on the other.

You may exit the calibration section, at any time, by pressing and holding the OPTION switch for 3 seconds, if entering calibration section by mistake or calibration gas is not available.

Wait 24 hours after initially supplying air and power to the GSM-60 sensor before initial calibration. It is not necessary to open the Front Panel to make adjustment. The calibration functions are operated through the OPTION and SELECT switches on the front panel.

After entering a valid password to maintenance menu, see Section 5.2.1

Calibration Process for MOS Sensors

The following calibration procedure must be followed whenever a 60-series part number appear in the part number of the instrument, examples 046526200 -0000, 04652-70836000

Humidification is required when calibration is performed. In addition to the standard flow demand regulator, cylinder of calibration gas you need ENMET humidifier assembly part number 037000-000

 Fill the humidifier with clean water to about ¾ full, connect the flow demand regulator to one side of the humidifier and connect the other side of the humidifier to the GSM-60 calibration/sampling port.

Warning: Be sure that the flow direction is correct, note the arrow on the humidifier , failure to do so will cause damage to the

GSM-60 instrument

 With the cylinder regulator and humidifier assembled follow the above steps to complete the calibration process

5.4.3A Low Cal/Zero Cal Adjust

A Low Cal function should be performed only when the GSM-60 sensors are exposed to clean uncontaminated air. Use a cylinder of 20.9% oxygen to provide a clean air reference if necessary. Attach the cylinder to the calibration adapter, attach the adapter to the instrument and allow gas to flow over the sensor for up to 4 minutes.

Enter the maintenance menu by repeatedly pressing OPTION switch, until the maintenance menu is displayed. See Figure 6,

GSM-60 Maintenance Menu flow chart.

The first menu available is the Low Cal/Zero Cal.

Press the SELECT switch 4 times to perform a Low Cal.



If the Low Cal/Zero Cal is successful , the display will change to Hi Cal/Span Gas.

If you wish to Hi Cal/Span Gas the sensor apply calibration gas. Proceed to gas calibration Section 5.3.1B

If you wish to Exit the maintenance menu, Press and hold OPTION switch until the Maintenance Menu is displayed then release. Then press OPTION switch until “Exit Maint Menu” appears and then press SELECT switch to return the instrument to the Operational Display

5.5 Flow Control Orifice

A 0.0225-inch diameter orifice is used to set the flow rate. In well-maintained medical air systems, this orifice should not clog.

However, if difficulty is experienced in maintaining flow rate examine this orifice; replace it if necessary.

Orifice location will depend on instrument sensor configuration.

Appendix A: CO Characteristics

ENMET

The Characteristics and Effects of Carbon Monoxide

Carbon monoxide is a colorless odorless toxic gas generated by incomplete combustion of a hydrocarbon fuel in air. It may be present where internal combustion engines, furnaces, boilers, and other combustion devices are present. It is toxic when inhaled because of its great affinity to hemoglobin, the oxygen carriers in the red cells of the blood. CO replaces the oxygen normally carried by the hemoglobin, and thus inhibits the delivery of oxygen throughout the body; the victim suffers from oxygen deficiency, and may die from asphyxiation. The symptoms and degree of danger resulting from exposure to CO depend upon the concentration of the gas and the length of exposure; this is shown in Figure 10 . The GSM-60 instrument is employed to warn the user of the presence of CO, and to facilitate the assessment of the degree of danger that he or she is exposed to.

Based upon knowledge of the effects of CO, the Occupational Safety and Health Authority (OSHA) has set limits on exposure to CO in the workplace. These are 35 ppm (parts CO per million parts air) as a time weighted average for an eight-hour day, and a maximum exposure of 200 ppm. For compressed air line applications, OSHA requires Grade D breathing air supplied, using a Compressed Gas

Association (CGA) definition (G-7.1). Depending on interpretation of the OSHA respiratory standard, 10 ppm and 20 ppm CO have been used as maximum limits and standard instrument alarm points.

If a CO sensor is installed, the GSM-60 has two preset alarm set points, at 10 ppm and 20 ppm CO, which are adjustable, but cannot be set below 5 ppm or above 50 ppm.

The curves below are for percent Carboxyhemoglobin with 50% being the top curve, 5% the bottom. %COHb is a measure of the amount of hemoglobin occupied by CO rather than oxygen. CO effects upon children, adults engaging in physical activity, and smokers, are more pronounced.
