• Dräger Polytron Pulsar 2, Planned maintenance Dräger Polytron Pulsar 2 19 At the left of the Alignment screen the Transmitter 'target' indicates the degree of misalignment but not (unlike the Receiver) its direction: First move the Transmitter around to be sure you have found the strong central peak in signal. Make slow adjustments, first vertically then horizontally, to maximise the signal strength. The final horizontal adjustment moves the circle from right to left, until the display matches the diagram. Tighten the eight screws progressively in rotation to avoid losing the alignment. The Transmitter

• Dräger Polytron Pulsar 2, 32 Dräger Polytron Pulsar 2 The Dräger Polytron Pulsar 2 Digital Interface AI500 16.8 Connector 2: EIA-RS-422/485 Serial Port Removable polarised connector Phoenix Contact MC 1.5/06-ST-3.81, 1.5mm 2 (16AWG) For two-wire operation Terminals 15, 17 and 16, 18 can be linked internally with jumpers, accessed by removing the front cover. The driver capability allows up to 32 AI500 units to be addressed in a in a four-wire multidrop system, giving access to a theoretical maximum of 128 Dräger Polytron Pulsar 2s. In practice, the number of units will normally be determined by considerations of polling rate. The node address of each unit in the range 1..32 is held in non-volatile memory

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 contamination. 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 Transmit

• Dräger Polytron Pulsar 2, 6 Dräger Polytron Pulsar 2 Understanding the system 4 Low-supply Mode. Flashes of increased intensity are output at a regular 2Hz rate. This is substituted for Alignment Mode if the Transmitter detects that the supply voltage dips below the specified range when tested with the lens heater on. This test is only carried out during alignment (and hence at the time of commissioning the detector) so that it cannot delay a gas alarm if this coincides with a deteriorating supply. 5 Fault Mode. Flashes of maximum intensity are output at a regular 1Hz rate. This is substituted for Normal Mode if the Transmitter has detected that a tube has failed or is intermittent. It is a
