Alarm Codes and Error Messages


ALARM MESSAGE
POSSIBLE CAUSE
POSSIBLE SOLUTION


High Temperature Alarm
The temperature has gone above the high temperature alarm point.
  1. Try to lower the temperature by turning heaters down or off, or by increasing or turning on cooling elements (such as fans or misters), or by a combination of both.
  2. Check the temperature probes.
  3. Check to see if a fan has failed.
  4. Check the alarm settings.


Low Temperature Alarm
The temperature has gone below the low temperature alarm point.
  1. Try to raise the temperature by turning heaters up or on, or by decreasing or turning off cooling elements (such as fans or misters), or by a combination of both.
  2. Check the temperature probes.
  3. Check to see if a heater has failed.
  4. Check the alarm settings. 

Probe Damage Alarm
A temperature probe is damaged or disconnected.
  1. Replace or reconnect the temperature probe. The control should recover automatically.
  2. If another probe is available, the control uses it. If probe averaging is on, the defective probe is excluded from the average.


Probe Deviation Alarm

The difference in measured temperatures between averaged probes is greater than 18°F (10°C).

  1. Check the temperature probes.

  2. Check to see if a cooling or heating element has failed.

  3. Check the alarm setting. 


Actuator Jam Alarm
The third digit shows which actuator (1 or 2) the alarm is for.
The control is attempting to open or close an inlet or other element operated by an actuator, and has not received the correct response from the positioning motor.
  1. Check the element controlled by the actuator to see if it is mechanically stuck.
  2. Check feedback wires for damage or improper installation.
  3. Recalibrate the actuator.


Error 1 - Growth Curve Error

The temperature set points for the growth curve are increasing or overlapping. Temperature set points must decrease as the curve steps increase.

  1. Change the temperature set points so that they decrease.

Error 2 - Actuator Error

The temperature set points for one of the actuators are overlapping.

The differential for step 1 must be lower than the set point for step 2, and so on.
  1. Check the actuator settings and make sure they do not overlap. 

Error 3 - SAVER Error
The PEC+SAVER is not in place when trying to save or restore settings
  1. Make sure the Saver is inserted correctly and then try again.
