Operating Instructions - Branick 475 Installation, Operation & Repair Parts Information

OPERATING INSTRUCTIONS _________________________________________________

Power Requirements & Charging instructions
▪ The system is powered by an internal Sealed Lead Acid (SLA) 12 volt rechargeable battery.
▪ Charge system by plugging the electrical cord into the charger socket on the back of unit, and the other end
into a 110/120 volt outlet.
▪ A completely flat battery could take up to 7 hours to charge to full.
▪ The charge time is dependent upon many factors including use, how often it is charged, etc. Once fully
charged, the system should provide up to 8 hours of continuous operation.
▪ Under no circumstances should the battery be left in a flat state, designated by a blank display or diagnostic
codes E10 or LO. This will significantly shorten battery life.
Inflator Power Up
1. Flip the ON/OFF button of the digital inflator to the on position.
2. Display will show the following:
a) LCD segment check
b) software version and model number
c) mode 'N2P' for approximately 6 seconds and then display 'PCL'
d) battery status and display 'HI' or 'LO'
e) default pressure setting '32 psi'
Adjustment of Parameters
Default Parameters
▪ Parameter nPC (Number of Purge Cycles) = 2
▪ Parameter OPS (Over Pressure Setting) = 0 psig
▪ Parameter LPL (Lower Purge Limit) = 10%
▪ Parameter Cti (NOT RELEVANT)
▪ Parameter tnP (Tank Pressure Limit) = 120 psi
▪ Parameter diF (Differential Pressure Limit) = 15 psi
Number of Purge Cycles (nPC) is adjustable between 0 and 5 cycles. Increase cycles to improve N2 tire purity.
Over Pressure setting (OPS) is adjustable between 0 and 29 psig. OPS will allow the inflation pressure to go
beyond the set pressure by the value assigned and then back down to the target pressure.
__________________________________________________________________________
When using the OPS function, the sum pressure must not exceed the tire manufacturer's maximum
__________________________________________________________________________
Lower Purge Limit (LPL) is adjustable between 10% and 50%. For tires with higher set pressures the low
pressure threshold can be increased to reduce time and can be coupled with an increased number of N2 cycles.
Tank Pressure Limit (tnP) is adjustable between 87 - 174 psi. This limit should be set to approximately 10 psi
lower than the incoming air pressure.
NOTE: Setting the Tank Pressure Limit too high will cause the air compressor to run continuously.
Differential Pressure Limit (diF) is adjustable between 15-58 psi. This is the pressure loss from the Tank
Pressure Limit before the supply valve is opened. Increasing this limit will lower the available N
tank before the system starts to generate more N
