Reporting the Air Interlock Status (T3P Only)
To report the air interlock status, issue the command:
RAI
The controller responds with a message, such as:
AI0 or AI1
where: 0 = false
1 = true
Reporting the Valve Interlock Status
To report the valve interlock status, issue the command:
RIN
The controller responds with a message, such as:
IN0 or IN1
where: 0 = false
1 = true
Reporting the Checksum Status
The checksum indicates the status of the unit’s A/D converter calibration. To report the status of the
checksum, issue the command:
R 52
The controller responds with the message:
CS
value
where:
value
: 0 = OK
1 = Error Condition
If the A/D calibration is OK, an example response is:
CS 0
If the A/D calibration is out of range, an example response is:
CS 1
If the controller detects a checksum error, perform a full calibration to correct the problem. Refer to page 41
for more information.
If your unit issues a checksum error when you power up the controller, or if the transducer’s readings are
incorrect, you may need to recalibrate the span of the A/D converter. Refer to
Calibrating the A/D Converter,
page 41, for more information.
If the checksum error persists after you perform a full system calibration, followed by a recalibration of the
span of the A/D converter, the error indicates a hardware failure of the EEPROM. Contact any MKS Service
Center, listed on the inside back cover of this manual, for assistance.
