The OE391-12 Modular Service Tool is a system operator interface that
provides a direct link to enable the system operator to view the status,
con
fi
gure, and adjust the setpoints of the VAV/CAV, MUA, VCB-X,
VCM, VCM-X, VCM-X E-BUS, RNE, SA E-BUS or VAV/Zone Con-
troller on the control system communications loop. However, this manual
only applies to VCB-X and VAV/Zone Controllers. See note in the inside
front cover for the list of manuals that pertain to other controllers.
The Modular Service Tool is housed in an attractive black plastic enclo-
sure. The display area is covered with a clear plastic bezel for protec-
tion of the display screen. The Modular Service Tool has a 4-line-by-
20-character display panel with adjustable contrast control and a 27-key
membrane keypad for data selection and entry. All keypad operations
are simple and straight forward, utilizing non-cryptic plain English
language messages. Menu-driven programming allows for easy setup
and operation without the need for specialized training. The Modular
Service Tool is supplied with a programmable 4 Gigabyte SD memory
card, (4) AA 1.5 V batteries, a wall mount, a DC power supply, a mini-
Din communication cable, and an E-BUS communication cable. The
mini-Din cable allows you to connect the Modular Service Tool to any
Orion controller which has a mini-Din connector socket for program-
ming, monitoring, and troubleshooting purposes.
The Modular Service Tool is also equipped with an EBC E-BUS port
and an RS-485 three conductor terminal block port. The E-BUS port and
included E-BUS cable are used for updating E-BUS Module software
(described in Appendix C). The RS-485 port is used for hard-wiring to
older controllers that do not have a mini-DIN connector socket.
The Modular Service Tool is designed to be hand-carried. Its rugged
plastic housing provides superior protection for the electronic compo-
nents housed inside. The Modular Service Tool is a top-quality service
tool that will stand up to the demands of the typical job site environment
for many years.
