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

Probe temperature sensor at Input n is defective.

FAULT

 

 

PROBE PV n INPUT FAULT

Probe PV sensor at Input n is defective.

PROBE n INPUT OUT OF

Probe at Input n is out of solution.

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.
