INSTALLATIoN
NOTE
For complete information regarding performance,
installation, operation, maintenance and
specifications of the GT3000 Series, refer to
instruction manual 95-8616.
No special or additional detector installation
requirements exist above and beyond the standard
installation practices documented in the GT3000
instruction manual.
The operating temperature range for the Safety Certified
GT3000 depends on the specific sensor being used.
Refer to the GT3000 instruction manual for details.
Other environmental operating specifications are
applicable as published in the general specifications
section in the GT3000 instruction manual.
The GT3000 operating power distribution system
should be designed and installed so the GT3000
terminal voltage does not drop below 12 Vdc when
measured at any specific location. The external system
providing power to the GT3000 must have over-voltage
protection that ensures supply voltage does not exceed
30 Vdc.
NOTE
All safety functions of the GT3000 are active
within 150 seconds of power-up without any user
action required.
CoMMoN MISUSE SCENARIoS
Refer to the Installation and Maintenance sections of
the instruction manual for information on avoidance and
resolution of common misuse scenarios. Applications
to avoid include the following:
- Locations where impact or other excessive
mechanical stress is likely.
- Locations where regular contamination from debris,
trash, snow, mud, etc. is likely to contact the sensor.
- Horizontal mounting of the GT3000 (see DEVICE
MOUNTING ORIENTATION section of the GT3000
Instruction Manual).
- Locations where sensor cross-sensitivity to other
gases will be a problem (see Appendix A of the
GT3000 Instruction Manual for details).
NOTE
If the user suspects that damage or misuse has
occurred to the GT3000, a full proof test shall be
performed.
START-UP AND CoMMISSIoNING
Commissioning Personnel
The Safety Certified GT3000 Toxic Gas Detector can be
commissioned by any qualified person with knowledge
of gas detection instruments and the configuration
device being used.
Refer to the Installation and Calibration sections
provided in the GT3000 instruction manual.
Configuration
A HART handheld device can be used to monitor
internal status or to modify the factory settings of the
GT3000. Refer to the GT3000 HART Communication
section of the instruction manual for guidance on using
HART communication.
NOTE
Prior to device configuration all alarm outputs
must be bypassed. The device is not safety
certified during configuration change activities.
NOTE
All configuration changes to the GT3000 must be
verified by the user via a proof test, power cycle
and re-check of settings, or other appropriate
method.
Configuration Protection
Upon completion of installation and commissioning, it
is required that the user password-protect the GT3000
safety related parameters that are accessible via HART
in order to prevent accidental or deliberate change
of configuration data during normal operation. To
password protect the GT3000, the user must set the
write-protect function to “on” and enter an 8 character
password.
The user will be required to disable write protect
prior to any future configuration changes, and must
re-enable write protect upon completion of these
changes to ensure that HART communication remains
non-interfering.
