Johnson Controls M4-CG Series - User Manual

M4-CG Series General Purpose Application
Controller Installation Guide
Application
The CG series general purpose application controllers
are well-suited for controlling a wide variety of facility
and HVAC equipment, including fan coils, air handling
units, packaged HVAC equipment, and central plant
equipment. CG series controllers run pre-engineered and
user-programmed applications.
CG series controllers include an integral real-time clock,
which enables the controllers to monitor and control
schedules, calendars, and trends, and operate for
extended periods of time as standalone controllers when
offline from the Metasys system network.
Communications Protocols
CG series controllers can communicate using multiple
communication protocols depending on model and
configuration. CGE controllers communicate using the
BACnet
®
/IP communication protocol. CGM controllers
communicate using the BACnet MS/TP, N2 or wireless
Zigbee
®
communications protocols, with the addition of
ZFR183x Pro Wireless Field Bus Routers.
Equipment controllers in BACnet/IP or BACnet MS/TP
communication mode are BACnet network-compliant
devices. The BACnet protocol is a standard for ANSI,
ASHRAE, and the International Standards Organization
(ISO) for building controls.
Controllers running in N2 mode can be used to maintain
or modernize sites with installed legacy Johnson Controls
®
controllers. For installation and commissioning support,
and tips for efficient and safe replacement, refer
to the Modernization Guide for Legacy N2 Controllers
(LIT-12012005) and the controller-specific documentation.
For information about mapping N2 Objects in controllers
with switchable communications protocols, refer to the
N2 Compatibility Options chapter of the Controller Tool Help
(LIT-12011147). To configure CGM series controllers to
communicate using the N2 communications protocol, see
Configuring N2 communications (CGM models only).
To configure CGM controllers to communicate using
the wireless communications protocol, see Configuring
wireless communications (CGM models only).
North American Emissions Compliance
United States
This equipment has been tested and found to comply
with the limits for a Class A digital device pursuant to
Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference when this equipment is operated in a
commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area may cause harmful interference, in which
case the users will be required to correct the interference
at their own expense.
Canada
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur du
Canada.
Installation
Observe the following guidelines when installing the
controller:
• To minimize vibration and shock damage to the
controller, transport the controller in the original
container.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
Parts included
• One CGM/CGE controller with removable terminal
blocks (Input/Output, Power, FC, and SA Bus terminal
blocks are removable)
• One installation instructions sheet
Note: The FC terminal block is only available with the
CGM model.
Materials and special tools needed
• Three fasteners appropriate for the mounting surface
(M4 screws or #8 screws)
• One 20 cm (8 in.) or longer piece of 35 mm DIN rail and
appropriate hardware for DIN rail mount (only)
• Small straight-blade (1/8 in. or 3.2 mm) or Philips #2
screwdriver for securing wires in the terminal blocks
