SKC PowerFlex User manual

PowerFlex Battery Charging System
Small and lightweight, the SKC PowerFlex®is an advanced charging system
designed for optimal charging of NiCad and NiMH baery packs for most SKC
personal air sampling pumps.
Pump-specific cables are used to connect baery packs to the PowerFlex so that
only one charger is needed for most SKC personal sample pumps (excluding Ex
and ATEX models and models with lithium-ion [Li-Ion] baeries). PowerFlex
fully charges baery packs in 6 to 8.5 hours, and then automatically switches
to a safe pulse trickle charge. An LED indicates baery charge status. Baery
packs can be charged aached to or detached from the pump.

Operation
Procedure for PowerFlex Activation
1. Plug the power cable into the power jack on the back of the PowerFlex. Plug
the wall cube into a power outlet (100-240 V).
If the LED lights red or green upon plugging the charger into the
wall outlet (no pump aached), discontinue use of the charger and
return it to SKC for repair.
Procedure for Charging AirChek 2000 Pumps
Aention AirChek 2000 Users: To prevent baery damage, follow the steps below
in the order indicated.
1. Ensure the sample pump is off.
2. Open the protective cover on the pump charging port by turning the cover 90
degrees counter-clockwise.
3. Connect the charging plug end of the charging cable
to the charging jack on the AirChek 2000 with the
keyed edge facing down. Caution: Forcing the plug
into the pack with the keyed edge facing up will cause
damage to the baery pack.
4. Insert RJ-45 connector on the charging cable into the
PowerFlex charging port.
5. Allow up to 60 seconds for the LED indicator to light
red. If it does not light, see Troubleshooting, Step 1.
6. The baery is fully charged when the LED indicator lights green.
7. Disconnect the RJ-45 connector on the charging cable from the PowerFlex
charging port.
8. Disconnect the charging plug end of the cable from the charging jack on the
AirChek 2000 baery.
9. Close the protective cover on the pump charging port.
Procedure for Charging Other SKC Pump Models
1. Ensure the sample pump is off.
2. Select the appropriate pump-specific cable.
3. Insert the RJ-45 connector into the charging port on the PowerFlex. The connec-
tor should slide easily into the port.
4. Insert the charging plug end of the cable into the charging jack on the appro-
priate sample pump.
AirChek 52 Note: Plug the charging plug end of the cable into the jack on the
back of the baery pack.

• PowerFlex line source is UL Listed for electrical safety, but the low-voltage
charger unit is not. Do not use PowerFlex in hazardous locations, in rain, or
in standing water. For indoor use only.
• Remove pump-specific cable from the charger when not in use to avoid
shorting.

5. The LED at the port will light a steady red to indicate that a charge sequence
has been initiated.
If the LED does not light red within 60 seconds, see Troubleshooting,
Step 1.
6. Once the baery pack is fully charged, the LED at the port will change to a
steady green to indicate that PowerFlex has switched to a trickle charge to keep
the baery at full charge.
7. The baery can be removed at any time aer the LED turns green. Detach the
baery from the cable and remove the cable from the charger.
Important Note: Pumps may remain connected to the charger indefinitely
(without causing damage to the pump or charger).
Important Note: Remove pump-specific cable from charger when not in
use to avoid shorting.
Troubleshooting
If the LED does not light when a baery pack is plugged into the port or the LED
does not turn offaer a baery pack is unplugged, follow the steps in the table.
Step Action No result, Action Yes result, Action
1 Keep the unit powered on. If the battery is
deeply discharged, the LED may take up to
30 minutes to light or turn off.
Go to Step 2 Proceed with operation
2 Move unit to a different wall outlet Go to Step 3 Proceed with operation
3 Unplug charger from its power source for
20 seconds. Plug it back into power source.
Go to Step 4 Proceed with operation
4 Replace pump-specific cable Go to Step 5 Proceed with operation
5 Try a different battery pack Call SKC Proceed with operation —
previous battery pack
may be damaged,
call SKC.

PowerFlex Technology
Charging NiCad/NiMH batteries is generally accomplished by applying constant current to the battery.
SKC PowerFlex Chargers use a technology that is new to industrial hygiene equipment batteries.
Reflex charging†delivers pulses of current instead of constant current to charge batteries. In between
pulses, PowerFlex applies short reverse pulses that discharge the battery slightly and short pauses.
This eases the battery into a full and uniform charge. It helps to prevent dramatic increases in internal
temperature and pressure that can damage the battery and shorten its life.
† Patented by Galaxy Power, Inc.
Note: Discharging the pump battery before charging is not necessary with this system
because the charging technology does not promote memory. However, if the user
desires to discharge before charging, simply run the pump until it stops, then
charge the battery.
