Figure 17 Status of AMS Tag (Diagnostics)
1 The Analog Output is at Beam-block level (2mA). However, the
cause has been removed and the Dräger Polytron Pulsar 2 is
expected to restart operation in a few seconds.
2 Gas reading shows a negative value. Before re-zeroing please
check for obstructions in the beam, misalignment or lens con-
tamination.
3 The signal-to-noise ratio is too poor for measurement. This
could be due to dense fog or an obstruction in the beam path.
4 The Receiver is unable to 'see' the Transmitter. Possible
causes: (1) Obstruction in beam path (2) Receiver and Trans-
mitter not set to the same channel (3) A nearby
Dräger Polytron Pulsar 2 set to the same channel (4) Transmit-
ter not powered (5) Transmitter and/or Receiver grossly mis-
aligned.
5 The Optics Warning flag is set because the signal strength is
very high. Please check that the appropriate attenuator plate is
fitted to the Transmitter for the Tx/Rx operating distance
6 The Analog Output is at Fault level (<1mA) because a Beam-
block state has persisted for longer than the configured time
limit
