ELECTRICAL
TOTAL ELECTRICAL ISOLATION BEFORE ACCESS
Any procedure that requires access to electrical components of the electronics of a
dispenser/pump requires total electrical isolation of that unit. Understand the function
and location of this switch or circuit breaker before inspecting, installing or servicing
Gallagher equipment.
10.1 Remounting a PULSE UI Battery Pack
On occasion the PULSE Battery BUP 4 x AA Pack Assembly, mounted on the inside of the
dispenser head cabinet door panel, may come loose and hang on the red and black wires
from the BUP board.
This is due to the shield surface not being oil and grease free when the Battery Pack was
initially mounted using double-sided adhesive tape.
To reattach the Battery Pack:
(a) Remove the old double-sided adhesive tape from the Battery Pack and any
residual tape stuck to the shield surface.
(b) Use Isopropyl alcohol or suitable degreaser to wipe the Battery Pack and shield
surface where the Battery Pack will be mounted (as shown below) near the BUP
board.
(c) Attach the Battery Pack to the shield surface using 3M VHB 4991 tape (or other
suitable double-sided adhesive tape), pressing firmly onto the shield surface for
a minimum of 10 seconds.
