■ LEAD-TIME COMPUTING
The module operates a lead-time equation.

Parameters
T : Lead-time constant (0.5000 to 100.0000 seconds)
• Step input with lead-time constant
INPUT
0
OUTPUT
0
■ RAMP BUFFER
The modules output does not change faster than a preset
maximum rate, positive CP and negative CN, no matter
how fast its input changes.
CP : Maximum rate of positive output change
(0.0000 to 200.0000%/second)
CN : Maximum rate of negative output change
(0.0000 to 200.0000%/second)
• Step input with rate-of-change limits
INPUT
0
OUTPUT
0
■ HIGH / LOW LIMIT
The output does not go above the preset high limit or
below the preset low limit.
High and Low limits are independently selectable.
■ USER'S TABLE LINEARIZATION
The input is converted into a linearized output according
to the user specified segment data table, defined with pairs
of X (input) and Y (output) values.
2 to 101 segment points can be specified.

■ OTHER FUNCTIONS
The low-end cutout point can be set within 0.0000
– 99.9999% of input signal.
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: M6CFG).
LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through power supply cables, use of appropriate lightning
surge protectors are recommended. Please contact M-Sys-
tem.
