Zero Calibration
This read-only parameter indicates the signal level detect-
ed when the controller measures its zero reference voltage
in performing its self-calibration. If the value drifts out of
specified limits, the controller places all loops in manual
mode at 0 percent power and indicates a hardware failure.
This parameter is available only for serial communications
and LogicPro.

Parameter Description Values Bit
Battery Status
Indicates whether the values in RAM
have been corrupted while the power
has been off.
0: No corruption detected
1: Data corrupted

perature is within the controller’s oper-
ating range. If the ambient is out of
range, the controller sets all loops to
manual mode at 0 percent power.
0: Within range
1: Outside of range
Fourth
Zero Status
Indicates whether the zero self-cali-
bration measurement falls within
acceptable limits.
0: In calibration
1: Out of calibration
Sixth
Full Scale Status
Indicates whether the full scale self-
calibration measurement falls within
acceptable limits.
0: In calibration
1: Out of calibration
Seventh
Power Up Alarm
Delay Status
Indicates whether the power-up alarm
delay feature is presently active. See
Power Up Alarm Delay on page 100.
