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 then 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 can not 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 alarm relay contacts available on terminals
continuous LCD display of gas and vapor concentrations a fault relay and visual fault alarm
menu driven operational and maintenance controls low air flow fault indication and display
menu driven calibration procedure alarm acknowledgement capability including audio defeat
audio and visual alarms indicate unsafe conditions 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.
