6. PARAMETER SETTING ORDER AND PRECAUTIONS
When setting a parameter, begin with Step 1 below and continue in sequence.
Range code No.
(IN)
You can begin with any of these parameters.
Alarm-1 action Alarm-2 action Alarm-3 action Alarm-4 action
(AL1) (AL2) (AL3) (AL4)
After that, you
may proceed with
settings beginning
at any parameter.
Step 2 Step 1
NOTE
If the settings for the range code No. (IN) or alarm actions (AL1 to AL4) are changed, the
relevant parameter setpoints shown in the table below will be initialized.
To change a parameter setpoint, begin with Step 1 above and continue in sequence.
Parameters to be initialized if the range code No. (IN) is changed
Alarm setpoints (A1 to A4), hysteresis (HY1 to HY4), setpoint (SP)
Max. and min. monitor output values (RTH, RTL)
Input adjustment point LOW (BL) and HIGH (BH), input adjustment LOW (AL) and HIGH (AH),
wiring resistance correction (WIR)
High and low limits for PV display color change (PCH, PCL)
Parameters to be initialized if the type of alarm action (AL1 to AL4) is changed
The alarm setpoint (A1 to A4) corresponding to each alarm action (AL1 to AL4)
(Example: If AL1 is changed, A1 will be initialized.)
Parameters to be initialized if the type of PV display color mode (PCM) is changed
High and low limits for PV display color change (PCH, PCL)
