In salt spray environments, it is
especially important to ensure that the
enclosure is sealed properly, including
all entry and exit points.
• Always install the ROC809 in a user-
supplied enclosure.
• If the ROC809 is installed outside
a building, it must be placed in a
National Electrical Manufacturer’s
Association (NEMA) 3 or higher rated
enclosure to ensure the necessary
level of protection.
• The ROC809 operates over a
wide range of temperatures.
In extreme climates it may be
necessary to provide temperature-
controlling devices to maintain
stableoperating conditions.
• In extremely hot climates, a filtered
ventilation system or air conditioning
may be required.
• In extremely cold climates, it may be
necessary to provide a thermostatically
controlled heater in the sameenclosure
as the ROC809.
• To maintain a non-condensing
atmosphere inside the ROC809
enclosure in areas of high humidity,
it may be necessary to add heat
or dehumidification.
I/O Configuration
Several options are available on the Type ROC809
controller. Outputs may be added to interface
with external devices such as systems for remote
data transmission, remote monitoring and remote
surveillance. Table 2 lists the minimal requirements.
NOTICE
Each module must be inserted in the
assigned slot as shown in Table 2.
Further configuration information is provided in the
Type Dosaodor-D Software for Configuration
of Type Dosaodor-D Odorant Injection System
Manual (D103117X012).
Refer to the ROC809 Remote Operations Controller
Instruction Manual (Form A6116).
Electrical Connections Schematics
The electrical connections between the enclosure and
pneumatic panel should be completed according to
Figures 7 and 8.
Preliminary Checks
Before turning on the electronic control unit:
1. Gas Volume/Gas Delivery signal type must be set
to one of the following input signals:
• Pulse input
• Analog input
• Internal Orifice
• Internal Turbine
2. Check all of the electrical and pneumatic
connections for proper conformity throughout the
entire system, using the diagrams and drawings
supplied by the system integrator.
3. Make sure that all of the valves for connection
between the pneumatic panel and remaining part
of the station are leak free. Turn on the electronic
control unit.
Control Unit Power-On and
Parameters Set-Up
After all of the checks in the preceding section and
suggested by the system integrator have been carried
out, turn on the system, set it in Disable mode and
configure parameters as described in:
