OUTPUT RANGING
The internal DIP switch setting is required to select output
types before setting a precise output range using PC Con-
figurator Software (model: M3SCFG).
For detailed information on the PC configuration, refer to
the M3SCFG users manual.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the RTD or its extension wires are broken, the output
goes over 100% (below 0% with downscale protection) due
to the burnout function. Confirm the status indicator
LED pattern and check leadwires in such a case.
4) Output: Check that the load resistance meets the de-
scribed specifications.
STATUS INDICATOR LED
The transmitter is provided with a status indicator LED
which blinks in different patterns indicating various oper-
ating status.
The following figure indicates typical patterns.

MAINTENANCE
Regular calibration procedure is explained below:
■
CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit using the PC Configurator
Software (model: M3SCFG).
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
