ESD Protection
ESD Precaution
Opening LCR.iQ Registers
Follow this procedure each time you open a LCR.iQ register or approach it with the door
open: Before opening the LCR.iQ register and handling the CPU board, it's important to
discharge any ESD that may have built up on your person. To discharge ESD from your
person, touch a well-grounded point–such as the LCR.iQ register housing, the meter, truck
piping, or the bumper. When the maintenance is complete and the LCR.iQ register door is
closed, the CPU board is protected from ESD by the LCR.iQ register housing which is
grounded to the chassis.
Preventing ESD Damage
To prevent electrostatic discharge (ESD) damage to the LCR.iQ electronic register, truck
installations must properly ground the truck seat cushion and the Epson printer chassis.
Prolonged exposure to ESD over weeks, months, or years can corrupt register memory and
damage the electronic components in LCR.iQ registers (as well as other electrical components
in the truck’s electrical system).
Adjustable, shock-absorbing seats, if not grounded correctly, generate significant amounts of
ESD. The pivots and hinges of these seats isolate the seat cushion from an electrical ground.
Without proper bonding, static electric charge builds between the seat cushion and the
operator. This electric charge can enter the LCR.iQ register from any point in the truck
electrical system, including register power and printer cabling.
Liquid Controls Grounding Kits
All LCR.iQ truck installations must have grounded seats and printers using the following kits:
·
LCR.iQ Ground Strap Kit (LC Part Number 82185)
·
Epson Printer Ground Wire Kit (LC Part Number 82184)
Properly grounded seats allow static electricity to ‘bleed off’ before it can build up, discharge,
and damage the LCR.iQ register or other electrical components.
