Response Factor; Alarm - Dräger PID 5000 Instrucciones De Uso

4.4.1

Response factor

A response factor must be entered in the PID 5000 based on
the calibration with isobutylene gas. This factor reflects the
sensitivity of the known volatile organic compound compared
to the calibration gas and can be set between 0.10 and 10.00
in steps of 0.01. The response factor depends on the oil type
to be measured, as different oils are stimulated at different
levels by the UV lamp.
WARNING
Danger due to incorrect measurement
Incorrect measured values are displayed if an incorrect
response factor is entered. Reliable measurement is not
ensured.
► Contact Dräger Service when determining the correct
response factor.
NOTICE
Due to the physical influences of the ambient conditions on
the behaviour of oil dissolved in air, deviations other than the
accuracy of the system in general (with regard to isobutylene)
may occur depending on the oil type and the measured value
reading. This was taken into account when determining the
correction factors so that the PID 5000 emits an alarm before
exceeding the limit value. This can mean that an alarm
sounds before a limit value is actually reached.
The approved oil types are listed in the table below.
Designation
Shell Corena S2P150
Shell Corena S2P100
Boge 3000
Other oil types upon request.
Change response factor
1. Select the instrument menu (see chapter 4.4 on page 12).
2. Use the magnetic pen to tap on "menu" until "SETTINGS"
appears on the display.
3. Select "change".
4. Select "Response". This accesses the screen for setting
the response factor.
5. Adjust the response factor (1) by tapping on "more" or
"less" and confirm with "accept".
6. The response factor currently set is shown on the bottom
right of the display (2).
4.4.2

Alarm

WARNING
Danger due to contaminated air
The delay before contamination is detected is set depending
on the ratio between the volume of the gas line and the
Air Guard or PID 5000 and the duration of the actual
measurement.
This is primarily due to the fact that the volume flow within the
Air Guard has to be greatly reduced for correct measurement,
whereas this does not result in a reduction in the volume flow
to the pressure vessels to be filled. This must be noted in the
event of any contamination.
► Clean contaminated pressure vessels as well as the
PID 5000 as required (see chapter 6.2.1 on page 15).
► Replace the Dräger-Tubes (5) for the gas treatment as
soon as contamination above the main alarm exists.
The PID 5000 is pre-assigned with the alarm threshold
pursuant to EN 12021. The pre-alarm is triggered at 0.1 mg/m³
and the main alarm triggers at 0.5 mg/m³. The same values are
also stored in the Air Guard.
WARNING
Danger due to failure of an alarm
A change in the alarm settings may mean that the alarm does
not trigger when the limit value is exceeded.
► Only adjust the alarm after consulting with Dräger Service.
The PID 5000 has two adjustable alarm levels:
"Alarm LO" (pre-alarm): 0.1 to 10 mg/m³

"Alarm HI" (main alarm): 0.2 to 10 mg/m³

NOTICE
"Alarm HI" (main alarm) must always be set higher than "Alarm
LO" (pre-alarm).
The set alarm levels only control the PID 5000's LEDs. The
Air Guard, to which the PID 5000 is connected, evaluates and
responds to the alarms.
Change alarm
CAUTION
When changing the alarm values on the PID 5000, also
change the alarm values in the Air Guard accordingly.
1. Select the instrument menu (see chapter 4.4 on page 12).
2. Use the magnetic pen to tap on "menu" until "SETTINGS"
appears on the display.
3. Select "change".
4. Select "Alarms". This accesses the screen for the alarm
setting.
