1.5 STATUS LED
S
Amplifier Status Information is useful for determining the condition of the tension amplifier and its network and
module operational state. Three bi-colored LEDs located on the front of the TA500-EIP provided this infor-
mation.
Amplifier Status LED
The Amplifier Status LED is a bi-color red/green LED. The state of the LED depends on the state of the ampli-
fier module. Wiring faults and/or overload conditions of transducer loadcells are indicated and can be decoded
using the table below. During normal operation, the status LED is showing a solid steady green. The amplifier
status information is also available of the data interface.

DEFINITION
OFF Power off.
Steady Green Normal operation.
Green, 1 Flash Device not calibrated.
Red, 2 Flash Over Range Condition: Once calibrated the TA500-EIP will indicate
an over range or under range condition by setting the error code to
‘Outside Cal Range’. The error is active once -20% or 120% tension
is exceeded - Action Required: To clear this error the tension must
be brought back into range, or a new calibration will need to be per-
formed to do so.
Red, 3 Flash Wiring Error: Will alert until the load cells are wired correctly - Ac-
tion Required: Check wiring and retry. Check for loose wires at the
terminal blocks, check for shorts, and be sure the load cells are
connected. If the transducers need trouble shooting – contact tech
support for assistance. Overload Condition (LT Transducer): Will
intermittently alert if overload is reached - Action Required: Check
that the tension range does not exceed the transducer load rating.
Reduce wrap angle to reduce effective net force exerted on load
cell.
Red, 4 Flash Excitation Failure or Wiring Error - Action Required: Check for
shorts in the transducer / load cell wiring. If the transducers need
trouble shooting – contact tech support for assistance.
Red, 5 Flash Internal Failure - Action Required: Contact DFE for replacement.
