For switching, it is necessary to:
- put the magnet to the recess on the detector (see figure 12) (a click will be heard),
- turn off the power for 5 seconds,
- turn on the power and remove the magnet in 5-10 seconds.
9.1.2 Automatic mode
Sensitive elements functionality is checked every 20...30 minutes by means of built-in
test radiation sources. Voltage is applied to them and the generated radiation falls directly
on the sensitive elements. If the value of the signals generated in this case exceeds the
specified threshold value, then the detector is considered to be operational. The
«Fire»
signal is not generated during the optical channels functionality check. If there is a failure
in the channel (optical signals are small), a
«Failure» signal is generated on LED
indicators, relay contacts, analogue and digital output signals. At the same time FD 330-4-
1 «VEGA» continues analyzing incoming optical signals. For visual status indication, a
three-color LED indicator is installed on the front of the detector, the glow mode of which
indicates the FD 330-4-
1 «VEGA» status.
9.1.3 Detector set up test program
Detector set up test program, besides the actual FD 330-4-
1 «VEGA» functionality
check, to additionally configure some parameters of its operation. For example, depending
on the characteristics of a particular operation object, the user can programmatically
control the degree of dustiness of the optics, activate the automatic heating mode of the
optics, and also configure other performance parameters of the FD 330-4-
1 «VEGA».
Using test programs, it is possible to switch the operating mode from Modbus to
HART, as well as from HART protocol to ModBus protocol.
Switching is performed using the
«HARTOn» button on the main tab,
Switching from HART to Modbus is performed via Dev-I
ce setup →Deta-Iled setup
→Sensors→Dev-Ice flags→Sett-Ings→Sw-Itch to Modbus →on → Enter→Send
