complete. donE PV input calibration completed
FAIL Calibration failed
Note. When a DC input module is installed for the first time, or there is a requirement to change one,
then the microprocessor in the controller needs to read the factory calibration data stored in the module.
Select ‘FACt’ as the calibration value. Step to ‘GO’ and start calibration.
DC Output Calibration
The following parameters apply to DC output modules ie for rcAL = 1A.Hi to 3A.Lo
cAL.H Output Calibration High 0 0 = Factory set calibration.
Trim value until output = 9V, or
18mA
cAL.L Output Calibration Low 0 0 = Factory set calibration.
Trim value until output = 1V, or
2mA
User calibration
UCAL User calibration enable Yes/no
pt1.L Low calibration point for Input 1 The factory calibration point at which the
low point offset was performed.
pt1.H High calibration point for Input 1 The factory calibration point at which the
high point offset was performed.
OF1.L Offset Low for Input 1 Calculated offset, in display units.
OF1.H Offset High for Input 1 Calculated offset, in display units.
pt2.L Low calibration point for Input 2 The factory calibration point at which the
low point offset was performed.
pt2.H High calibration point for Input 2 The factory calibration point at which the
high point offset was performed.
OF2.L Offset Low for Input 2 Calculated offset, in display units.
OF2.H Offset High for Input 2 Calculated offset, in display units.
