1.8 STARTUP AND OPERATION
Before starting the EF-Series Unit, perform the following checks to ensure the unit is properly
installed.
♦ Make sure the enclosure has a good earth ground connected to the earth ground bus inside the
enclosure.
♦ Check the field wiring for proper installation. Refer to Section 2.
♦ Make sure the input power has the correct polarity.
♦ Make sure the input power is fused at the power source.
CAUTION
It is important to check the input power polarity before turning on the power.
Incorrect polarity can damage the EF-Series Unit.
CAUTION
When installing equipment in a hazardous area, ensure that all components are
approved for use in such areas. Check the product labels.
1.8.1 Startup
Apply power to the EF-Series Unit by plugging the input power terminal block into the connector
labeled POWER located at the bottom left of the Main Electronics Board. After the EF-Series Unit
completes start-up diagnostics (RAM and other internal checks), the LCD displays the date and time to
indicate that the EF-Series Unit completed a valid reset sequence. If the LCD does not come on, refer
to the Troubleshooting and Repair paragraphs in Section 2 for possible causes.
1.8.2 Operation
Once startup is successful, it is necessary to configure the EF-Series Unit (see Section 2.6 for more
information) to meet the requirements of the application. The ROCLINK User Manual provides
detailed information for using the ROCLINK software to configure the EF-Series Unit and to calibrate
its I/O (see Section 2.7 for more information about calibration). Once the EF-Series Unit is configured
and calibrated, it can be placed into operation.
CAUTION
Local configuration or monitoring of the EF-Series Unit through its LOI port must
be performed only in an area known to be non-hazardous.
During operation, the EF-Series Unit can be monitored (to view or retrieve current and historical data)
either locally or remotely. Local monitoring is accomplished either by viewing the LCD panel detailed
in Section 2.4.3, or by using ROCLINK on a PC connected through the LOI port (see the ROCLINK
User Manual). Remote monitoring is normally performed through the host port of the EF-Series Unit,
using the eFlow Internet Measurement Services (IMS).
