4 to 20mA DC (linear or square root) with digital signal superimposed on the 4 to 20mA signal
Power supply
:
Transmitter operates on 10.5V to 45V DC at transmitter terminals.
10.5V to 32V DC for the units with op-tional arrester.
Load limitations
:
see figure below
Note: For communication with HHC(1) (Model: FXW), min. of 250 required.
Hazardous locations: (Under an application) SEE TABLE2 Zero/span adjustment:
Damping
:
Zero and span are adjustable from the HHC(1). Zero and span are also adjustable externally from the adjustment screw.
Adjustable from HHC or local configurator unit with LCD display.
The time constant is adjustable between 0.06 to 32 seconds.
Zero elevation/suppression:
-100% to + 100% of URL
Normal/reverse action:
Selectable from HHC(1)
Indication
:
Analog indicator or 5-digit LCD meter, as specified.
Burnout direction
:
Selectable from HHC(1)
If self-diagnostic detect transmitter failure, the analog signal will be driven to either "Outphut Hold", "Output Overscale" or "Output Underscale" modes.
"Output Hold"
:
Output signal is hold as the value just before failure happens.
"Output Overscale"
:
Adjustable within the range 20.0mA to 22.5mA from HHC(1)
"Output Underscale"
:
Adjustable within the range 3.2mA to 4.0mA from HHC(1)
Output limits conforming to NAMUR NE43 by order.
Loop-check output:
Transmitter can be configured to provide constant signal 3.2mA through 22.5mA by HHC(1).
Temperature limit
:
Ambient: -40 to +85°C
(-20 to + 80°C for LCD indicator)
(-40 to +60°C for arrester option)
(-10 to +60°C for fluorinated oil filled transmitters)
For explosionproof units (flameproof or intrinsic safety), ambient temperature must be within the limits specified in each standard.
Process: -40 to +120°C for silicone fill sensor
-20 to +80°C for fluorinated oil fill sensor
Storage: -40 to +90°C
Humidity limit
:
0 to 100% RH
Communication
:
With HHC(1) (Model FXW, consult Data Sheet No. EDS8-47), following items can be remotely displayed or configured.
Note: HHC's version must be higher than 7.0 (or FXW .......1---...4), for FCX-AIII.
Local configurator with LCD display (option)
Local configurator with 3 push button and LCD display can support following items
Programmable output linearization function:
Output signal can be characterized with "14 points linear approximation function" from HHC(1).
