5. Notes on use
Based on the measurement results and the specifications of test report PFG No. 41300504P, the P3U transmitter (Polytron
7000) made by Dräger Safety AG & Co. KGaA is suitable for oxygen measurements within a measuring range of 0 to 25 % O2
(regarding its use for ambient air monitoring for oxygen deficiency or excess oxygen), in as far as its characteristics and its
design matches the records stated in the test report PFG No. 41300504P, is operated accordingly and if the conditions stipu-
lated below are met:
— The instructions for use made available to and examined by EXAM are to be followed precisely. The stipulated operating con-
ditions are to be met when using the gas warning device.
— Prior to using the gas warning device, the time settings are to be checked to ensure that the warning function of the device is
triggered early enough to avoid critical safety conditions. If necessary, the alarm level is to be set high above (or, depending
on the application, below) the safety limit value.
— The German BG Chemie-Information BGI 836 (3) are to be observed.
— A permanent identification tag is to be applied to the devices, which, in addition to information on manufacturer, type and pro-
duction order number, is labelled as follows:
This does not render other obligations to mark the device invalid. With this identification tag, the manufacturer confirms that
the devices described tin this report have the specified characteristics and technical features. Any device without this identi-
fication tag does not correspond with this report.
— On request, the operator is to receive a complete copy of this report as well as one of the test report PFG No. 41300504P.
— The relay module may only be operated with devices equipped with software version 7.8 (main).
— Alarms must always be configured as "Cannot be acknowledged".
— If the pump module is used, the flow rate alarm must be activated.
— The O2 LS sensor must always be installed at vibration-free locations when used in combination with the pump module.
