TEST METHOD FOR OPTIMAIR MASK-MOUNTED PAPR
TEST METHOD FOR THE OPTIMAIR
MASK-MOUNTED PAPR
The test method should only be used if
any one of the OptimAir Mask-Mounted
PAPR components (charger, battery
pack, or motor-blower) is not function-
ing properly. This method will outline the
steps needed to evaluate the proper
electrical functions of each of the com-
ponents of the Mask-Mounted PAPR. A
digital multimeter is required.
Testing the Charger:
The OptimAir Mask-Mounted PAPR
comes standard with a dual-rate
smart-charger. This charger has a sta-
tus indication LED. There is no testing
of the charger. The LED will indicate if
there is a problem during charging.

LED Color
Status
Description
Red
Rapid Charge
Charger is supplying maximum current
to battery pack for charging.
Green
Charge Complete
Battery Pack is charged and a
maintenance charge is being delivered
to offset self-discharge.
Amber
Charge Pending
Battery Temperature is outside the
charge range. If the battery is too hot,
charge will not begin until temperature
falls. If temperature is too low, charger
will trickle charge until the battery
temperature increases sufficiently
to begin rapid charge.
Red Flash
Charge Failure
Charger failure can occur in any one of
four ways:
1) No Thermistor – This will be checked
in the battery pack test.
2) No Voltage – This will be checked in
the battery pack test.
3) Clock Time Out – This occurs when
charger fails to transition to
maintenance charge from rapid
charge. In this case the clock turns
the charger off before cell damage
can occur.
4) Over Temperature – This can occur if
the batteries become too hot
during rapid charge.
*If the charger fails, refer to "Testing the
Battery Pack" section. You will need to
determine if the battery pack or the
charger is bad.
Off
No AC/Battery
If the LED is off then the unit is not
plugged in, or there is no battery
attached to the charger.
