COMMUNICATIONS
The use of communications such as serial and ethernet
in industrial environments are commonplace. The proper
installation of these networks is as important to the proper
operation of the communications as all of the preceding
practices are to the equipment.
Serial communications cable needs to be of the proper gauge
based on the total cable distance of the run. Daisy-chaining
is the only acceptable style of running the communications
cable. While Star Networks may use less cable, they more
often than not cause problems and interruptions in communi-
cations, due to varying impedances over the varying lengths
of cable. Ground or drain wires of the communications cable
are to be tied together at each daisy-chain connection and
only taken to ground in the central control system panel.
It is important to carefully consider the type of cable to be
used. Just because a cable has the proper number of conduc-
tors and is shielded does not mean it is an acceptable cable.
Johnson Controls-Frick recommends the use of Belden #9829
for RS-422 communications and Belden # 9841 for RS-485 up
to 2000 feet (600 Meters) total cable length. Refer to Frick
drawing 649D4743 for more detail
Comm port protection:
Surge suppression for the comm
ports may not be the best method, since suppression is re-
quired to divert excess voltage/current to ground. Therefore,
the success of these devices is dependent on a good ground
(covered earlier in this section). This excess energy can be
quite high and without a proper ground, it will access the
port and damage it.
Isolation or Optical Isolation is the preferred comm port
protection method. With optical isolation, there is no con-
tinuity between the communications cable and the comm
port. There is no dependence on the quality of the ground.
Be sure to know what the voltage isolation value of the
optical isolator is before selecting it. These may range from
500 to 4000 Volts.

Optical Isolation Kits are offered under part number
639C0133G01. One kit is required per comm port.
UpS pOWER AND QUANTUM
™
HD pANELS
Johnson Controls, Inc. does not advise nor support the use
of uninterrupted power supply systems for use with the
Quantum
™
HD panel. With a UPS system providing shutdown
protection for a Frick Quantum panel, the panel may not
see the loss of the 3-phase voltage on the motor because
the UPS may prevent the motor starter contactor from
dropping out. With the starter contactor still energized, the
compressor auxiliary will continue to feed an “okay” signal
to the Quantum
™
HD panel. This may allow the motor to be
subjected to the fault condition on the 3-phase bus.
A couple of fault scenarios are: 1. The 3-phase bus has
power “on” and “off” in a continuous cycle manner which
may cause the motor to overheat due to repeated exces-
sive in-rush current experiences. 2. The motor cycling may
damage the coupling or cause other mechanical damage
due to the repeated high torque from rapid sequential motor
“bumps.” 3. Prolonged low voltage may cause the motor to
stall and possibly overheat before the motor contactor is
manually turned off.
Under normal conditions, the loss of 3-phase power will
shut down the Quantum
™
HD panel and it will reboot upon
proper power return. If the panel was in “Auto,” it will come
back and return to running as programmed. If the unit was
in “Remote,” the external controller will re-initialize the
panel and proceed to run as required. If the panel was in
“Manual” mode, the compressor will have to be restarted
manually after the 3-phase bus fault/interruption has been
cleared / restored.
If the local power distribution system is unstable or prone
to problems there are other recommendations to satisfy
these problems. If power spikes or low or high line voltages
are the problem, then a constant voltage (CV) transformer
with a noise suppression feature is recommended. Johnson
Controls, Inc. can provide these types of transformers for
this purpose. Contact Johnson Controls for proper sizing (VA
Rating) based on the requirement of the job. If a phase loss
occurs, then you will typically get a high motor amp shut-
down. If the problem continues, an analysis of the facility’s
power supply quality may be necessary.
NOTICE
It is very important to read the installation instructions thoroughly before beginning
the project. Make sure you have drawings and instructions for the equipment being
installed. If not, call the manufacturer to receive the proper instructions and draw-
ings. Every manufacturer of electronic equipment should have a knowledgeable staff,
willing to answer your questions or provide additional information. Following correct
wiring procedures will ensure proper installation and consequently, proper operation
of your electronic equipment.
