Purkeys Fleet Electric consults with many customers about Forklift battery issues that result from electronic scales which can discharge the batteries too low causing service interruptions. This often happens over weekends. For that reason, we have developed a unique solution to rectify the problem.The Purkeys Fleet Electric Forklift LVD turns off the electronic scale on the forklift when the battery voltage drops to 12.2 volts and remains there for 15 seconds or more. The power to the scale resumes when the forklift is started and the module sees a voltage of 13.2 volts or higher.
The principals of operation for the PFE-LVD require that the Forklift battery is 12.3 volts or higher. The green LED on the LVD will illuminate and the control module will provide power to the relay coil. With the relay coil powered, the relay’s contact will close, thus the scale system will be powered.
When the forklift battery voltage drops below 12.3 volts for more than 60 seconds, the red LED light will illuminate and the control module will not provide power to the relay coil. The relay‘s contacts will not be closed, thus the scale system will not have power and will turn off.
After the control module turns off for low voltage, it will stay off until the forklift unit is started and the module sees more than 13.2 volts. When it sees this voltage level, it will again power the relay coil, the contacts will close and the scale system will have power.
The PFE-Forklift LVD is easy to mount and install and fully automated to ensure total satisfaction.
