3.4.1 Booting up the Gas Detector
When turning on the power to the Gas Detector it has a boot-up time of 60 seconds. During
this time the Detector will run self diagnostics and if the indicator is configured to be active it
will show yellow light. After this boot-up time the Detector is ready to detect gas, but for a very
precise testing of gas accuracy the Detector should be allowed for another 20 minutes warm
up time
3.4.2 Performing loop test
The PG11 can perform a loop test through the HART of MODBUS interfaces. The loop test
allows for the Operator to Manually set the analog signal output to a selected value for a
limited time. Please consult the corresponding HART chapter of this Manual for instructions.
