K-TEK MT5000 - 4.5.8 HART Address; 4.5.9 LRS (HART Version Only)

MT5000-0200-1 Rev f (10-2010) DCN0528 22
HART ADDRESS is a selection which will allow the user to assign a numerical ad-
dress to the MT5000. Setting the address of the unit will allow the MT5000 to be
polled when installed in a string of transmitters. The HART ADDRESS may be set
to any number from 0 to 15. As a default value, the MT5000 is set with an address
of 0. This allows the MT5000 to operate normally. If an address other than 0 is set
in the MT5000, the mA output of the transmitter will hold at 4.00mA and the meas-
ured level will continue to operate as normal.
To enter a HART ADDRESS:
1. Press and hold the SELECT button for 2 seconds.
2. Scroll UP or DOWN to set each digit.
3. Press the SELECT button to set the digit and move to the next digit in se-
quence.
4. After the last digit is set, press the SELECT button to set the new PROBE
LENGTH.
5. Scroll UP to END MENU.
6. Pressing the SELECT button now will return you to the main screen.

Low Range Saturation is the lowest current output that the transmitter can attain in normal operation (not
in alarm condition), regardless of the actual measurement value. The LRS limit has no effect on the ―Fail
Low‖ alarm current (3.60mA if selected) with the Fail Hi/Lo jumper position on the face of the module.
Should the transmitter lose its echo, the transmitter will immediately enter its low alarm state (no damping
effect) of 3.60mA. LRS has two selections:
 3.85 sets 3.85mA as the low limit for the mA signal. As the level decreases below the LRV, the output
current will change proportionally, down to the limit.
 4.0 sets 4.0mA as the low current limit from the transmitter, preventing a ―negative‖ level in the control
system.
