7. SWITCHING PARAMETERS
CAUTION
●
If the alarm action (AL1 to AL4) is set to "OFF," the relevant alarm setpoint (A1 to A4)
is not displayed.
●
If no keystroke is made for more than 2 minutes, the PV screen automatically
appears, regardless of the parameter displayed. In this case, if a data change is in
progress (the decimal point is blinking), the data being changed becomes invalid and
the PV screen appears with the previous data displayed as is. However, this action
does not take place if the parameter "MAN", "ZER" or "SPN" is being displayed.

Alarm-1 setpoint (A1)
Sets the alarm-1 setpoint.
Alarm-2 setpoint (A2)
Sets the alarm-2 setpoint.
Alarm-3 setpoint (A3)
(Displayed only for 4 points of alarms)
Sets the alarm-3 setpoint.
Alarm-4 setpoint (A4)
(Displayed only for 4 points of alarms)
Sets the alarm-4 setpoint.
Alarm-1 action (AL1)
Sets the direction of alarm-1 action.
(See the Alarm Action Type Codes table in Section 9.1.)
Range code No. (IN)
Sets the range code number (input type).
Measured input bias (BS)
This parameter is set to correct a measured
input value.
PV display color mode (PCM)
Sets the Active color PV display.
Economical mode time (ECO)
This parameter is set to extinguish the display
(not including the READY and alarm lamps) if no
keystroke is made for a specified time.
Input adjustment reset (RST)
Used to reset an input adjustment value.
Input adjustment point LOW (BL)
Sets the reference value corresponding to
0% of the input when an input adjustment is
made.
Input adjustment LOW (AL)
Adjusts the 0% value of an input.
Input adjustment point HIGH (BH)
Sets the reference value corresponding to
100% of the input when an input adjustment
is made.
Input adjustment HIGH (AH)
Adjusts the 100% value of an input.
Alarm-2 action (AL2)
Sets the direction of alarm-2 action.
(See the Alarm Action Type Codes table in Section 9.1.)
Alarm-3 action (AL3)
(Displayed only for 4 points of alarms)
Sets the direction of alarm-3 action.
(See the Alarm Action Type Codes table in Section 9.1.)
Alarm-4 action (AL4)
(Displayed only for 4 points of alarms)
Sets the direction of alarm-4 action.
(See the Alarm Action Type Codes table in Section 9.1.)
Alarm-1 hysteresis (HY1)
Sets the hysteresis of alarm 1.
Alarm-2 hysteresis (HY2)
Sets the hysteresis of alarm 2.
Alarm-3 hysteresis (HY3)
(Displayed only for 4 points of alarms)
Sets the hysteresis of alarm 3.
Alarm-4 hysteresis (HY4)
(Displayed only for 4 points of alarms)
Sets the hysteresis of alarm 4.
Alarm ON delay (OND)
Sets the condition monitoring time from the
establishment of alarm conditions to its
output.
Alarm OFF delay (OFD)
Sets the condition monitoring time from the
establishment of return-to normal conditions
to its output.
Setpoint (SP)
When using a deviation alarm, this
parameter is set to the value treated as the
reference for deviations.
Key lock (LOC)
This parameter is set when change of parameter
settings (all parameters or parameters other than the
operation parameters) is locked to prevent wrong
operations.
Visibility of monitor output adjustment screen (MON)
Sets the visibility of the screen for adjusting monitor
output. Pressing the SET/ENT key with "ON"
displayed on the DATA display causes the
adjustment screen to appear.
Forced output of a monitor output value (MAN)
Used to force a value equivalent to -25% to +125%
of an analog output value to output, regardless of
input.
Monitor output zero adjustment (ZER
)
Adjusts the zero point of the monitor output.
Monitor output span adjustment (SPN
)
Adjusts the span of the monitor output.
Maximum monitor output value (RTH)
This parameter is set to treat any value as
the maximum output value with respect to
the input range.
High limit for PV display color change (PCH)
Sets the high limit for PV limit mode or SP
deviation mode of Active color PV display.
Low limit for PV display color change (PCL)
Sets the low limit for PV limit mode or SP
deviation mode of Active color PV display.
Minimum monitor output value (RTL)
This parameter is set to treat any value as
the minimum output value with respect to the
input range.
Communication protocol (PSL)
Sets the communication protocol.
Communication address (ADR)
Sets the communication address.
Baud rate (BPS)
Sets the baud rate.
Parity (PRI)
Sets the parity.
Stop bit (STP)
Sets the stop bit.
Data length (DLN)
Sets the data length.
