12.2 System Status Messages
Overview
The following table lists all the error messages that can appear for Measurement errors,
Input errors, Output errors, and Alarm Conditions.
Table 12-1 Status Messages
Status Message Definition
HOLD ACTIVE Analog Inputs (PVs) are held at their last active levels by
pressing the “HOLD” button, until cancelled by pressing the
“HOLD” button again.
n = 1 or 2 Measurement Errors
TEMP n UNDERRANGE
Measured temperature
is less than the minimum range value
according to measurement type, where:
n is 1 (Input 1) or 2
(Input 2).
TEMP n OVERRANGE Measured temperature is greater than the maximum range
value according to measurement type, where:
n is 1 (Input 1)
or 2 (Input 2).
PV n UNDERRANGE Measured PV is less than the minimum range value according
to measurement type, where
n is 1 (Input 1) or 2 (Input 2).
PV n OVERRANGE Measured PV is greater than the maximum range value
according to measurement type, where
n is 1 (Input 1) or 2
(Input 2).
n = 1 or 2 Input Errors – Output(s), for which Input is source, will go to failsafe level
PROBE TEMP n INPUT
FAULT
Probe temperature sensor at Input
n is defective.
PROBE PV n INPUT FAULT
Probe PV sensor at Input
n is defective.
PROBE n INPUT OUT OF
SOLUTION
Probe at Input n is out of solution.
TEMP n INPUT OPEN
Probe temperature sensor at Input
n is not connected. Check
Wiring.
PV n INPUT OPEN
Probe PV sensor at Input
n is not connected. Check Wiring.
INPUT BOARD n FAULT An input board disconnect while powered results in an input
fault condition and this status message. The PV value is the
failsafe parameter value and the temperature is at the lower
limit of the input board’s temperature range.
Re-insert the input board, or cycle the unit’s power if the input
board is no longer needed.
n = 1, 2, or 3 Output Errors – Output in error goes to failsafe level
OUTPUT n OPEN Analog output n current is less than 3 mA and is less than
output minimum mA value. Check wiring.
n = 1, 2, 3, or 4 Alarm Conditions
ALARM n ACTIVE
Alarm number
n is currently active.
