Modification Code

S: Modifiable at any time.
P: Modifiable only when the MAINTENANCE SWITCH is in

the “PRG” mode.

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.

4) Output: Check that the load resistance meets the de-

scribed specifications.

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 according to the “ANALOG
OUTPUT ADJUSTMENT” procedure.

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.
