Model MR Operation and Installation Manual
Setup
Notes:
In program mode, the transmitter will not respond to incoming HART commands. This function will prevent a user at a remote terminal from overwriting
a parameter that is being entered at the same time from a local site.
Program Mode Timer
After you enter the programming mode, a one-minute timer is started. Each time you press a button, the timer is reset. If you do not press a
menu button within one minute, the timer will expire and the transmitter will return to the run mode.
Loop 1 and Loop 2 Test Ports
Using a standard multi-meter set the meter to DC current and attach across the terminals, loop current can be read directly from ports 1 and 2
(see Figure 14). The current read on the meter should correspond with the data being displayed. These ports allow the loop current to be read
directly without having to interrupt power.
HART Port
This port allows for direct connection of the HART field calibrator or other HART host device as long as there is a load on loop 1.

LCD DISPLAY AND KEYPAD (OPTIONAL)

A sixteen character, seven-segment LCD display and three push-button "keypad" option is available. Level and temperature measurements are
displayed when in run mode. When power is applied to the unit, a start" message is displayed. Then, while in run mode, the display is updated
every three seconds with new data. There are three data fields on the display [Level 1, Level 2, Temperature]. If a measurement is not available,
there will be dashes (- - - - -) shown in the corresponding field.

ALARM SETTINGS

When a fault condition is detected by the internal microprocessor, the 4 to 20 mA current will go to the selected alarm mode. If in the 4 mA
alarm mode when a fault is detected, the output will be continuous at 3.8 ± 0.1 mA. If in the 20 mA alarm mode when a fault is detected, the
output will be continuous at 21.5 ±0.2 mA.

MANUAL CALIBRATION

The procedure to enter calibration mode and modify levels 1 and 2, adjust LCD contrast and perform a LCD testis shown in Figure 15 on the
next page.
