and receiving device and avoid placing the transmitter and receiving device between obstructions,
whenever possible.
2.1.2.6. TRANSMITTERS WITH A USB DATA LOGGER CARD
Transmitters with a USB datalogger card write sensor data to a thumb-drive memory device. Inspect and
verify the following:
A USB thumb drive memory device is properly seated in the USB connector on the data logger card.
To avoid data loss and/or damage do not insert or remove a thumb drive memory device into the USB
connector on transmitter with the power switch in the “ON” position.
2.1.3. Power Connections
Inspect and verify the following:
24 VAC power is connected to both power terminals of the transmitter.
Multiple transmitters wired on a single transformer are wired “in-phase” between transmitters (L1 to
L1 and L2 to L2).
The power transformer has been sized for the total load of all of the devices connected.
2.1.3.1. EB-FLOW2 TRANSMITTERS
Inspect and verify the following:
The secondary of the 24 VAC transformer is not connected to ground.
Grounding the power on the secondary side of the transmitter results in non-isolated output signal(s)
which may result in ground loops, signal error, and/or damage to the transmitter. Do not use a
grounded 24 VAC power source.
Grounding the primary side of the transformer is not a problem as long as one leg of the secondary or
a center tap of the secondary is not connected to ground.
If devices requiring 24 VAC require grounding, use a separate transformer to power the
transmitter(s).
2.2. POWER-UP
Move the power switch to the “ON” position. The transmitter will display the firmware version and conduct
power-up diagnostics prior to normal operation. Power-up faults, if detected, are displayed on the display.
EF-x2000 transmitters do not have a power switch. The transmitter is energized when 24 V power is
provided to the device.
If “live” power is connected to the EF-x2000 power terminals, take extreme caution not to contact
other terminals or the any component on the circuit board. Connecting power to terminals other than
the power terminals may damage the transmitter and void warranty. It is advised that the 24 V power
source is not “live” when the power connections are made.
