Quantum Identification

Frick Controls has over the years, strived to remain on the
cutting edge of microprocessor
development. And because of the ever-increasing speed,
memory, features and power of microprocessors, Frick
Controls will, from time to time, introduce the latest
advancement in microprocessor control technology.
Our microprocessor family has shared
Quantum, over the past five years. There are currently
four controllers within this family. The first two of these
controllers (known as Quantum 1 and Quantum 2) are no
longer in production, and as such, will not be further
mentioned in this manual. The two current members in
production of the Quantum family are the Quantum 3, and
the Quantum 4. It is critical to the end user to be able to
identify the differences between these controllers. Refer to
the section in this manual entitled "Quantum 3 Main Board
History and Identification" and "Quantum 4 Main Board
History and Identification" for additional information as to
how to identify the particular Quantum controller that you
have.
Throughout this manual, the two different controllers will
be talked about for the most part as one (as they do
function the same). Where there is a difference between
these boards, as in jumpers or wiring, the different models
will be identified by name. This is why it is important for
you to be aware of which Quantum board you have.

THE QUANTUM CONTROL PANEL

This section contains information on troubleshooting and
making corrections to the boards and control circuits of the
Quantum. Reference the drawings at the end of this
manual.

GENERAL INFORMATION:

The components within the control panel can be
inadvertently damaged
mishandling. Only qualified
directly handle these components.
1. DO NOT attempt to make corrections to the power
supply without shutting off the power to the control
panel. Accidental shorts can irreparably damage
the processor boards or the display screen.
2. DO NOT HANDLE the panel boards when their
cables are disconnected without first attaching a
properly grounded wrist ground strap to prevent
static electrical discharge from your body.
Most problems encountered with the microprocessor and
control circuits will be the result of a wiring fault, a blown
fuse, faulty I/O module or failure of a peripheral control
such as a solenoid coil or a pressure transducer. Faults in
the computer, while possible, are unlikely. If a fault
develops in the computer, the probability is that all
functions will cease and the display screen will go blank.
The control system of the compressor consists of an AC
(high voltage) side, which can be either 120 volts, or 230
volts, and a DC (low voltage) side. The AC side actuates
solenoids, relays, alarms, and other electromechanical
functions. The DC side operates the computer and it's
various sensors.
When working within the panel, the AC high voltage
side, which can be either nominal 120 VAC or nominal
230 VAC, CAN CAUSE INJURY OR DEATH.
To troubleshoot the low-voltage side of the control circuits,
it is necessary to have the following tools:
1. Accurate digital multimeter*
2. Small wire stripper
3.
Small screwdriver
4.
Small snip nose pliers
5.
Wrist Grounding strap*
6.
Static free grounded work surface
Note: Proper panel voltage refers to the AC (high volt-
age) that has been supplied to the panel which could
be either nominal 120 VAC or nominal 230 VAC
(Reference the Control Panel Power Specifications).
Some problems that
troubleshooting the panels digital inputs and outputs. The
Digital I/O (Input/Output) boards have six Digital I/O (DIO)
board connectors labeled P1 through P6. The input and
output modules are wired into a DIO connector plug.
Position 3 pro-vides power and position 4 is a neutral on
the DIO connectors.
