DESCRIPTION
The Universel Model 33 Retrofit Electronic Computer is an electronic computer designed to
replace existing mechanical registers currently used in various fuel dispensing devices. It
incorporates all the reliability and accuracy of modern electronics in a compact package that
fits in mechanical dispenser housings. This allows an upgrade to electronics at a considerably
lower price than a new dispenser. A hand held keyboard is provided to allow user access to
read totals, make price changes, and other programming functions. A user defined security
code (PIN) prevents unauthorized access to the programming functions. A power backup within
the unit allows the last sale to be displayed for a minimum of 15 minutes if the AC power
should fail.
The Universel Retro Computer can work by itself as a full service dispenser or be used with
various Control Systems for remote control operation. The Retro is designed to allow several
different applications for the unit.
INSTALLATION
[WARNING]
THERE MUST BE A GOOD EARTH GROUND CONNECTED TO THE UNIT TO
PREVENT DAMAGE. THE WARRANTY COULD BE VOIDED BY IMPROPER
INSTALLATION. (SEE THE WIRING DIAGRAM)
The Universel Retro Computer is designed to bolt into the existing mechanical computer location.
There is a maximum of ten wires to connect depending on the configuration of the existing unit.
Since the Retro Computer has a built in pulser and handle switch, there are two mechanical
linkages that are required for installation. There is one linkage between the meter and the
computer and one linkage between the handle and the computer. The existing linkages from
the existing pump can be used. The linkages are not supplied by Universel Epsco.
The appropriate wiring diagrams are included in the rear of this manual. Make sure that you
are using the correct diagram for your application.
To install the Retro, the following steps need to be accomplished in the order that they are
listed.
1. Turn off all power to the unit.
[WARNING]
FAILURE TO DISCONNECT ALL POWER FROM THE UNIT COULD RESULT
IN ELECTRICAL SHOCK.
