SM425 INSTRUCTION MANUAL 8.0 DETAILED DATA SETTING
For semi-automatic calibration, “under calibration” is the time between initiating a calibration by
input contact signal or from the touch panel screen and completion of output stabilization.
For automatic calibration, “under calibration” is the time between initiating a calibration by the
timer settings and the completion of output stabilization.
4. During “Blow back” (see Section 1.54, “Blow back”):
During semi-automatic blow back: “During blow back” is the time required after pressing the blow-
back start key using the touch panel or entering a blow back start instruction by using a contact
input, until the completion of blow back and output stabilization.
During automatic blow back: “During blow back” is the time required after reaching the blow-back
start until the completion of blow-back and output stabilization.
5. On Error occurrence: This is the time at which any of Errors 1 to 4 occurs.
8.2.2 Preference Order of Output Hold Value
The output hold value takes the following preference order:
For example, if the output current is preset for 4 mA for the maintenance operation and no output hold is
selected for calibration, the output current will be held at 4 mA during maintenance until a calibration
begins. The output hold will be released during the calibration cycle and will return to 4 mA at the
competion of calibration and stabilization.
8.2.3 Configuring the Output Hold
Use the following procedure to set the output hold function:
1. Press the Setup key in the Basic Panel display screen to display the Execution/Setup display
screen. Select Commissioning (Setup) then “mA-output setup”. Select “Set presets”. The mA-
output preset display screen shown in Figure 8-2 appears.
