SECTION 15 - FEATURES
DESCRIPTION OF FEATURES
1. Power
a. The VPL operates on 24 volts DC power supplied by two 12VDC, 12AH (amp hour) batteries. The
batteries are charged by a built in “smart charger.” Household power (120VAC) is used to operate
the charger and is supplied by an outdoor rated 12’ power cord. AC power requirements are low,
less than ½ amp at 120VAC.
The AC power cord must be connected to a grounded and polarized receptacle.
b. In the event of a power failure, the VPL is designed to operate approximately 20 cycles on battery
power before recharging the batteries is required.
One “cycle” is the VPL moving up-and-down once or down-and-up once.
c. The batteries require approximately 6 hours to fully charge if totally discharged.
VPL cycles and recharge times are highly dependent on outside temperatures and loads.
Low temperatures decrease battery performance and increase charging time.

2. Control Panel
a. The VPL Operator Control Panel incorporates operational controls as well as function indicator
lights. Control functions and features are as follows:
b. Keyed Power Switch: When turned to the Power On position, the keyed power switch permits VPL
operation. When turned to the Power Off position the VPL will not ascend or descend.
c. The key is removable in both the On and Off positions. If AC power is disconnected from the VPL,
leaving the key in the On position will discharge the batteries over about 7 days. The batteries will
charge with the key switch in either the On or Off position provided the unit is plugged into AC
power.
Removing the key from the keyed power switch does not disconnect power to the battery
charger. The only way to disconnect power to the battery charger is to unplug the VPL from
the AC outlet.
