Johnson Controls CGM04060 Installation Manual

Application
The CGM09090 and CGM04060 General Purpose
Application MS/TP Controllers (CGMs) are equipment
controllers that run pre-engineered and user-
programmable applications, and provide the inputs and
outputs required to monitor and control a wide variety
of HVAC and other facility equipment. CGM controllers
operate on an RS-485 BACnet
Advanced Application Controllers (B-AACs) and integrate
into Johnson Controls and third-party BACnet systems.
®
CGM equipment controllers include an integral real-
time clock, which enables the controllers to monitor and
control schedules, calendars, and trends, and operate for
extended periods as stand-alone controllers when offline
from the Metasys system network.
Communications Protocols
The CGM controllers can communicate using BACnet
MS/TP, N2, or wireless Zigbee
controllers communicate using the BACnet MS/TP
protocol. The BACnet protocol is a standard for ANSI,
ASHRAE, and the International Standards Organization
(ISO) for building controls.
The CGM controllers can be used as functional
replacements for legacy N2 controllers. The N2-capable
MS/TP equipment controller models provide a cost-
effective upgrade and modernization path for customers
with existing N2 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 controllers to communicate using
the N2 communications protocol, see
communications.
The CGM controller can also be installed in a wireless
application using a ZFR183x Pro Wireless Field Bus Router.
To configure these controllers to communicate using
the wireless communications protocol, see
wireless communications.

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 a CGM
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 controller with removable terminal blocks
(Input/Output, Power, FC, and SA bus terminal blocks
are removable)
• One installation instructions sheet
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
