The LTV
®
Series ventilator operates on Direct Current (11 to 15 VDC), supplied by an external AC to
DC power adapter, an external battery or other suitable external DC power source such as the
Pulmonetic Systems Universal Power Supply or Transport Battery System. The ventilator can also be
powered for short periods of time by its own internal battery (see note below).
• When the ventilator is connected to an appropriate external power source, the ventilator’s
internal battery is continuously charged and will reach 90% charge status within 8 hours.
• When the power connector on the ventilator is connected to the AC power adapter, the ventilator
is isolated from the power supply mains.
• If an LTV
®
Series ventilator is allowed to operate on its internal battery to the point that the
internal battery is completely depleted, the ventilator will shut down. If the ventilator remains in
this state, the internal battery may recharge slightly within a few seconds / minutes and cause
the ventilator to automatically restart and operate for a short period of time. This cycle can repeat
several times, depending on the condition of the internal battery.
NOTE
The Charge Status LED is illuminated green when the internal battery is charged to >90% of its
capacity. If the Charge Status LED is red, is flashing amber for more than 1 hour, or does not show a
green Charge Status indication after 24 hours, the battery is defective and should be replaced.
Please immediately contact a certified Pulmonetic Systems’ service technician.
Internal Battery Use: The internal battery is intended for use during short periods while switching
between external power supply connections, emergency situations or short duration transports. The
length of time the ventilator will operate on internal power is a function of many factors such as
settings, charge level and condition or age of the battery; therefore, the use of the internal battery as
a standard operating practice is not recommended.
REMARQUE
Le voyant du DEL Charge Status est vert lorsque la pile interne est chargée à plus de 90 % de sa
capacité. Si le voyant du DEL Charge Status est rouge, qu’il est jaune et clignote pendant plus d’une
heure, ou qu’il n’affiche pas un Charge Status vert après 24 heures, la pile est défectueuse et il faut
la changer. Veuillez communiquer immédiatement avec un technicien de service certifié par
Pulmonetic Systems.
Utilisation de la batterie interne: La batterie interne est conçue pour être utilisée sur de courtes
périodes pendant la commutation entre des connexions d’alimentation externe, les situations
d’urgence ou les transports de courte durée. La durée pendant laquelle le ventilateur fonctionnera sur
l’alimentation interne dépend de plusieurs facteurs tels, la configuration, le niveau de la charge et la
condition ou l’âge de la batterie; l’utilisation de la batterie interne pour l'opération normale n’est donc
pas recommandée.
