TS4000
Table 5: Gas Combination Table
WARNING:
When operating the TS4000 under the above conditions, all personnel operating
and maintaining the units should be notified of the cross-sensitivity issues that
are present at the site.
CAUTION:
Do not paint the TS4000 assemblies.
•
If the Base Unit is painted, the LED display cannot be read.
•
If the Interface Module is painted, the gas is not able to diffuse into the
sensor.
3.3 Installation Overview
The TS4000 is shipped without the electrochemical cell installed. The electrochemical cell must
be installed into the Interface Module and calibrated for proper operation. For wiring
connections, refer to Section 3.5. For calibration instructions, refer to Section 4.9.
Once correctly installed, the TS4000 requires little or no maintenance other than periodic
calibration checks to ensure system integrity. For optimum performance, General Monitors
recommends establishing a calibration check schedule and that the complete system, including
all alarm circuitry, is tested annually.
The mounting and overall dimensions for the TS4000 should be used when making installation
determinations. For Mechanical Specifications, refer to Section 9.5.
3.3.1 Intrinsic Safety Barrier
The TS4000 has an Intrinsic Safety Barrier within the Interface Module. The Intrinsic Safety
Barrier allows the user to change (hot swap) the electrochemical cell without powering down
