ADDING MODULES IN THE FIELD
Modular construction allows ease in adding strips of counters in units of 5 or 10. To install, first
turn off all power to the Electric Keytrol and pump. Then remove the locked bezel. Remove a
blank panel (held with two screws). Loosen the four appropriate terminal block screws, removing
the jumper between terminals C and D. Carefully install the counter module with its spade
terminals behind the lower support bar and into the terminal block. Make certain all 4 terminals on
the module are behind the screw heads of the terminal block. Reinstall and tighten the two screws
holding the module first. Then, tighten the four terminal block screws. Check the position of the
lockout switches to ensure that the desired units are on. Check each counter for operation.
Record the starting number. Reinstall bezel.
PULSER INSTALLATION ON EXISTING REGISTERS
Electric Keytrol’s may be retrofitted to an existing dispensing system, which requires installation of
a pulser. The pulser must be installed so that an active keyswitch will not record pulses during a
reset cycle. To accommodate this restriction, the pulser should drive off the center extended
shaft, which does not turn during the reset cycle. Another method is to wire one leg of the pulser
through an isolated, normally open switch in the electric reset or control handle switch housing
which will then close when the motor or solenoid valve is activated after reset is complete. This
method allows the pulser to be driven by the gallon wheel which turns during the reset cycle.
