Adjustable operation timer (in days)
— Dräger Pac 3000 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 Dräger Pac 3000 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.

Alarms
6.1
Concentration Pre/Main Alarms
— An optical and acoustical alarm are activated whenever alarm
threshold A1 or A2 is 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 4.) "Acknowledgeable":
alarms and LED can be acknowledged by pressing
[OK]
.
— "Latching": The alarm will only deactivate when the concentration
falls under the alarm threshold and then
[OK]
is pressed.
— 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]
.
— 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 battery.
— The battery is part of the Ex approval.
— Only the following battery types shall be used:
— Duracell 123 Photo, Lithium, 3 V
— Duracell 123 Ultras, Lithium, 3 V
— Panasonic CR 123A, Lithium, 3 V
— Energizer EL 123A, Lithium, 3 V
— Powerone CR 123A, Lithium, 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.
— After changing the battery a sensor warm up time of approx.
15 minutes is needed. The gas name flashes until the warm up
time has passed.
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 Safety 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. 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. Dräger Pac 3000 will
not longer measure and may be returned to Dräger Safety for
recycling.
6.6
Instrument alarm
— The alarm and LED will be activated three times, periodically.
— The
[X]
icon is flashing, a 3 digit error code is shown in the
display.
— If an error appears in the display see section 6.7 and if
necessary please contact DrägerService.
