Example Set a high limit alarm (alarm value = 1000) on
alarm number 1 of channel 02 and output to
relay I01.
SA 02,1,ON,H,1000,ON,I01
Description • When the input range is set to SKIP (SR
command), p3 cannot be turned ON.
• The alarm settings are all turned OFF for the
following cases.
• When the input type is changed (VOLT,
TC, etc).
• When the range type is changed.
• When the span and scaling values are
changed during linear scaling (includes
changing the decimal position).
• The h and l settings of p4 are valid only when
the measurement range is set to computation
between channels.
• The hysteresis of alarm ON/OFF (valid when
p4 is H or L) is set using the XA command.
• If p4 is set to R or r, set the interval for the
high/low limit on the rate-of-change using the
XA command.
• The T and t settings of p4 can be specified
when the alarm delay function is enabled (UF
command).
• If p4 is set to T or t, set the alarm delay time
for the delay high/low limit alarm using the BD
command.
• Parameter p5 for the high limit alarm/low limit
alarm and delay high limit alarm/delay lowlimit
alarm
• For DC voltage, TC, and RTD input: Values
within the measurable range in the
specified range (example: –2.000 to 2.000
V for the 2 V range).
• For ON/OFF input (DI): 0 or 1.
• For scaling (1-5V, scaling, and square
root): −5 to 105% of the scale span (except
within −20000 to 30000).
• Parameter p5 for the difference high limit
alarm/difference low limit alarm: Values in the
measurable range can be specified (example:
–1760.0 to 1760.0°C for the TC type R).
• Parameter p5 for the high limit on rate-of-
change alarm/low limit on rate-of-change
alarm: A value greater than or equal to 1 digit
can be specified. For example, 1 digit
corresponds 0.001 for the 2 V range
(measurable range: –2.000 to 2.000 V). The
maximum value that can be specified is the
4-12
Relay ON
Relay OFF
width of the measurable range (4.000 V for 2
V range). For ON/OFF input, only "1" can be
specified.
• On models with the computation function (/M1
option), alarms can be set on computation
channels.
• When the computation equation setting
(SO command) is turned OFF, p3 cannot
be turned ON.
• For computation channels, the alarm types
that can be specified are H (high limit
alarm), L (low limit alarm), T (delay high
limit alarm), and t (delay low limit alarm). T
and t can be specified when the alarm
delay function is enabled (UF command).
• If p4 is set to T or t, set the alarm delay
time for the delay high/low limit alarm using
the BD command.
• Set p5 within the range –9999999 to
99999999 excluding the decimal using an
integer.
• The alarm ON/OFF hysteresis is set using
the XA command.
• If the computation channel ON/OFF state,
the computing equation, or the span value
is changed, all alarm settings of that
channel are turned OFF.
SN Sets the unit.
SN p1,p2<terminator>
Syntax
p1 Channel number
p2 Unit string (up to 6 characters)
Query SN[ p1]?
Example Set the unit of channel 02 to M/H.
SN 02,M/H
Description • The unit setting is valid on channels set to 1-
5V, scaling, or square root.
• For the characters that can be used for the
units, see appendix 1, "ASCII Character
Codes."
• On models with the computation function (/M1
option), unit can be set on computation
channels.
SC Sets the chart speed.
