Universal Control
The Universal Control is the command center for the
machine. The software program for the UVC3 control,
including multiple language selections, resides in the
erasable programmable read-only memory (EPROM)
chip. The EPROM chip is not used on the UVC4
Universal Control.
The settings in the menus are saved in the random
access memory (RAM) chip. Removing and reinstalling
the software chip will restore the factory default settings
in the menus. The RAM chip must be inserted with the
notch towards the side of the socket with the notch.
Power is supplied to the 5 VDC terminal on the UVC3/
UVC4 board from the interface board. The operating
voltage range for the control is 4.75 VDC to 5.25 VDC.
Note:
Beginning with software version 1.07, the default
settings can be restored in the Service Menu. This can
only be done when the unit is in a Unit Cleaned State.
The unit must be cleaned or the W-2 on the shake side
interface board must be jumped out to enter a Unit
Cleaned State. (See “Reset to Defaults” on page 2-12.)
Note:
For installations with low voltage supply (210V or
less) it may be necessary to wire the 16 VAC transformer
on the low voltage tap. Low voltage supplied to the
interface board, in turn reduces the voltage supplied to
the UVC3/UVC4 board and may cause intermittent power
failure tripping or the control panel keys do not function
when the unit is powered.
The UVC3/UVC4 communicates with the control panel
interface board through a USB Cable.
There are three sets of pins on the UVC3 board and four
sets of pins on the UVC4 board. Refer to the following
chart to identify their function.
Note:
Use Part No. 040084-001 Connector-Programing
Shunt to jumper pins.

UVC4 Electrostatic Discharge and Proper Handling
Procedures
The UVC4 board is more susceptible to electrostatic
discharge than the UVC3 board. Always use the
following procedures to prevent damage when handling
the board.
1. Leave boards in their anti-static packaging until they
are ready to be installed.
2. Dissipate static electricity before handling the board
by touching a grounded metal object, such as the
unit's unpainted metal chassis.
3. If possible, use anti-static devices such as wrist
straps and floor mats.
4. Always hold the board by its edges. Avoid touching
the contacts and components on the board.
5. Take care when connecting or disconnecting cables.
A damaged cable can cause a short in the electrical
circuit.
6. Prevent damage to the connectors by aligning the
connector pins before connecting the cable.
Misaligned connector pins can cause damage to
components at power-on.
7. When disconnecting a cable, always pull on the cable
connector or strain-relief loop, not on the cable itself.
