Quantum™ Identification
Frick Controls has over the years, strived to remain on the
cutting edge of microprocessor technology and
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 the name
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.
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 board you have.

TROUBLESHOOTING
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 by static electricity or
mishandling. Only qualified technicians should
directly handle these components.
1. DO NOT attempt to make corrections to the power
supply without shutting off 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 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 are encountered involve
troubleshooting digital inputs and outputs.
The Digital I/O (Input/Output) board has six connectors
labeled P1 through P6. The input and output modules are
wired into a DIO connector plug. Position 3 provides 120
VAC power and position 4 is neutral.
The GCU Board has three digital inputs connectors,
labeled J7, J9, and J10. Each of these connectors has 16
pins. J10 is utilized for AC inputs, and use odd pin
numbers for 120 VAC signals, even pins for neutral. J9
and J10 are for AC outputs, and use even pins for 120
VAC hot, odd pins are for 120 VAC signals.
