Operation
Commissioning
The gas transmitter is set on delivery in accordance to the details in the table "Configuration of
the gas transmitter" on page 19 or built-to-order (if requested). The configuration is shown on
the device label. The device has been factory-calibrated, so after finishing the electrical instal-
lation, the device is ready to operate.
To avoid false alarms, the alarm activation at the central device is to be locked.
z
Supply the system with power. The gas transmitter runs an internal self-test
z
the status indicator's lights flash alternately for a short time. During the following warm-up
phase (warm-up time), the green status light is on and the yellow status light flashes. After
1 minute, operation begins using the configuration that was set upon delivery.
Check the zero-point and the sensitivity.
z
Check signal transmission to central device and alarm activation.
z
Unlock the alarm activation at the central device to put the system back to normal operating
z
mode.
Safety Integrity Level
– The gas transmitter is suitable for use in SIL 2 applications.
For applications with Safety Integrity Level (SIL) and any other configuration (when applica-
ble), observe the technical handbook.
Measuring mode
The gas transmitter generates a 4 to 20 mA signal, proportional to the measured gas concen-
tration, when the gas transmitter is configured for analogue signal transmission.
Current Meaning
4 mA zero-point
20 mA full-scale deflection
Special Conditions
<1.2 mA fault, configurable
2 mA beam block warning, configurable
3 mA maintenance signal, configurable
3.8 mA ... 4 mA deviation below zero point
20 mA ... 20.5 mA full-scale deflection exceeded (over-range)
>21 mA Device Error
Fault messages are issued with a higher priority than warning messages. Warning messages
are issued with a higher priority than measured values.
Maintenance
Maintenance intervals
Observe EN 60079-29-2 and respective national regulations.
Daily
Visual inspection to determine readiness for operation – the green status light lights up.
z
While commissioning
Check the function of the yellow and green status lights while the automatic self-test is run-
z
ning.
Check zero-point calibration.
z
Check the current interface and if required also the HART communication.
