Indication

Issue

Issue / Possible Cause(s)

Corrective Action

Alarm won’t clear

or reset

Alarm will not clear or re-

set with keypad or digital

input

• Alarm will not clear or reset via

device or digital input.

• Latching is active

• Alarm set to incorrect output

• Alarm is set to incorrect source

• Sensor input is out of alarm set

point range

• Alarm set point is incorrect

• Alarm is set to incorrect type

• Digital input function is incorrect

• Reset alarm when process is

within range or disable latching

• Set output to correct alarm source

instance

• Set alarm source to correct input

instance

• Correct cause of sensor input out

of alarm range

• Set alarm set point to correct trip

point

• Set alarm to correct type: process,

deviation or power

• Set digital input function and

source instance

Alarm won’t occur Alarm will not activate

output

• Silencing is active

• Blocking is active

• Alarm is set to incorrect output

• Alarm is set to incorrect source

• Alarm set point is incorrect

• Alarm is set to incorrect type

• Disable silencing, if required

• Disable blocking, if required

• Set output to correct alarm source

instance

• Set alarm source to correct input

instance

• Set alarm set point to correct trip

point

• Set alarm to correct type: process,

deviation or power

Alarm Error 1

Alarm Error 2

Alarm Error 3

Alarm Error 4

Alarm state cannot be

determined due to lack of

sensor input

• Sensor improperly wired or open

• Incorrect setting of sensor type

• Calibration corrupt

• Correct wiring or replace sensor

• Match setting to sensor used

• Check calibration of controller

Alarm Low

[1,2,3,4]

Sensor input below low

alarm set point

• Temperature is less than alarm set

point

• Alarm is set to latching and an

alarm occurred in the past

• Incorrect alarm set point

• Incorrect alarm source

• Check cause of under temperature

• Clear latched alarm

• Establish correct alarm set point

• Set alarm source to proper setting

Alarm High

[1,2,3,4]

Sensor input value is

above high alarm set

point

• Temperature is greater than alarm

set point

• Alarm is set to latching and an

alarm occurred in the past

• Incorrect alarm set point

• Incorrect alarm source

• Check cause of over temperature

• Clear latched alarm

• Establish correct alarm set point

• Set alarm source to proper setting

Error Input [1,2] Sensor does not provide

a valid signal to controller

• There is no valid signal to the de-

vice. The sensor may be improp-

erly wired or open.

• Incorrect setting of sensor type

• Calibration corrupt

• Correct wiring or replace sensor

• Match setting to sensor used

• Check calibration of controller
