Figure 16 Status of AMS Tag (Dräger Polytron Pulsar 2 Status)
9 Upper Range Value - The gas reading which produces an Ana-
logue Output of 20mA and a Percent Range of 100%. It is not
recommended to set the URV below 4.0 LFLm unless the oper-
ating environment is clean and dry, the ambient temperature is
relatively stable and the measurement beam will not be
obstructed.
10 Analog Output Value- Value that tracks the Digital Value repre-
sentation, under normal operating modes.
11 The Supply voltage measured by the Receiver is the applied
voltage less the voltage drop in the cable.
12 Signal strength depends on the operating distance and the
presence of fog. Misalignment of the Transmitter and the
Receiver and dirt on their lenses can also affect this value.
13 The internal temperature of the Dräger Polytron Pulsar 2
Receiver. Normally a few degrees above ambient temperature
due to internal power consumption and the lens heater.
1 Please state this error code if you need assistance from the
service support centre.
2 The 4-20mA Analog Output is at Fault level (<1mA) because of
a Hardware Fault or because Beam-Block has timed out to
Fault. Please see Diagnostics Tab.
3 The 4-20mA Analog Output is at Beam-block level (2mA). The
Dräger Polytron Pulsar 2 is unable to detect gas for some rea-
son. Please see Diagnostics Tab.
4 The supply voltage at the Receiver end of its cable is out of lim-
its. This is not yet affecting the operation.
5 The internal temperature of the Receiver is unusually high or
low. This is not yet affecting the operation.
6 Transmitter reports some Xenon tube mistriggering OR the dig-
ital link between the Receiver and the Transmitter has broken.
The Dräger Polytron Pulsar 2 remains operational but should
be serviced if this indication persists. The sensitivity to gas is
not affected.
7 The Transmitter is not pointing exactly towards the Receiver.
This is not yet affecting the operation.
8 Receiver Misalignment Pre-Warning”, The misalignment of the
Receiver towards the Transmitter exceeds 50% of the allowed
range OR the Receiver lens is partially obstructed. This is not
yet affecting the operation.
9 Warning of Attenuator plate absent from Transmitter OR pre-
warning of dirty lens. Please see Diagnostics Tab.
