Drager Pac 5000, Инструкция по применению

Страница: 3 / 3

5.9 Calibration and configuration
— For calibration or individual configuration connect Pac
5000 to a PC using the connecting cradle or the E-Cal
System. Calibration and configuration can be done with
installed software Pac Vision or CC Vision. A calibration
“due date” can be set using the operation timer (in days).
5.10 Adjustable operation timer (in days)
— Pac 5000 is equipped with an adjustable operation timer.
The operation timer can be used to set an individually
operation period e. g. to adjust a “calibration due date”,
an “inspection due date”, an “out of order date” etc.
— To adjust the operation timer connect Pac 5000 to a PC
using the connecting cradle or the E-Cal System. The
adjustment can be done with installed software Pac
Vision or CC Vision.
6 Alarms
6.1 Concentration Pre/Main Alarms
— The alarm will activate whenever the alarm thresholds A1
or A2 are exceeded. The instrument is equipped with a
vibrating alarm. It vibrates in parallel to these alarms.
— During an A1, the LED will blink and the alarm will sound.
— During an A2, the LED and alarm tone will repeat in a
double repeating pattern.
— The display will alternate between the measurement value
and “A1” or “A2”.
— The alarms may, according to the selected configuration,
be acknowledged or turned off. (See section 2.)
“Acknowledgeable”: alarms and LED can be
acknowledged by pressing [OK] for 1 second.
— “Latching”: The alarm will only deactivate when the
concentration falls under the alarm threshold and then
[OK] is pressed for 1 second.
— If the alarm is not latching, the alarm will deactivate as
soon as the concentration falls under the alarm threshold.
6.2 Battery pre/main alarms
— When the battery pre-alarm is activated, the audible alarm
sounds and the LED blinks, and the “low battery” icon
»
« flashes.
— To acknowledge the pre-alarm, push [OK] for 1 second.
— After the first battery pre-alarm, the battery will last for
approx. 1 further week and the “low battery” icon stays lit.
— When the battery main alarm is activated, the audible
alarm sounds in a repeating pattern of 2 repeating tones
and the LED blinks in the same pattern.
— The battery main alarm is not acknowledgeable; the
instrument will automatically turn off after approx. 1
minute.
— In case of a very low battery, the internal voltage monitor
could activate the LED’s.
6.3 Changing the battery
— Do not change the battery in explosion-hazard areas!
— The instrument contains a replaceable lithium ion battery.
— The battery is part of the Ex approval.
— Only the following battery types shall be used:
— Duracell DL 123 Lithium Type CR123A, 3 V
— ………
— ………
— Turn the instrument off.
— Unscrew the 4 screws from the back case.
— Open the front case and remove the depleted battery.
— Insert the new battery according to specified polarity
(+/–).
— Place front case back and fasten it by tightening the 4
screws of the back case.
6.4 Handling of exhausted batteries
— Caution:
— Never throw them into a fire!
— Never attempt to charge them!
— Never attempt to open them, danger of explosion!
— Dispose of exhausted batteries only as special waste in
accordance with local regulations.
— Spent batteries may be returned to Dräger for disposal.
6.5 Usable life alarm
— Before the end of the instrument’s usable life, a warning
period begins. During this period the remaining life time
flashes just after turning the instrument on, e. g. “30”/“d”.
— To acknowledge this message [OK] must be pressed for
approx. 1 second. After that, the instrument can be used
further.
— After the usable life has expired the text “0“/“d“ will
alternate in the display and cannot be acknowledged.
Pac 5000 will not longer measure and may be returned to
Dräger for recycling.
6.6 Instrument alarm
— The alarm and LED will be activated three times,
periodically.
— The [X] icon will be lit, with a 3 digit error code shown in
the display.
— If an error appears in the display see section 6.7 and if
necessary please contact DrägerService.
