Error (cont.)

Notes

Er05

Name:

Display Firmware Integrity Failure

Description:

The display firmware has failed to pass its CRC CCITT checksum integrity test.

Response:

The display performs this check at startup and the display board will fail to startup without any error indication if it

does not pass this at power on.

Er06

Name:

Micro Firmware Integrity Failure

Description:

The micro firmware has failed to pass its CRC CCITT checksum integrity test.

Response:

This is checked at power on reset and the “Er06” will be displayed for ~10 seconds at startup if this condition

exists.

Er07

Name:

Micro Fail - CS5521 SPI Failure / UISR Failure

Description:

This condition indicates a micro board failure due to either the SPI bus is unable to communicate with the ADC

device or a UISR event caused the microcontroller to be in an unstable state.

Response:

The unit will try to recover from this fault three times by a hardware reset of the micro board. In the event that the

system couldn’t rectify the issue, the following sequence of events will occur:

Remote alarm contacts will become active.

Buzzer will annunciate audibly and will have a ringback of 15 minutes.

“Seven segment” display will show “Er07”.

The system will have 10 minute staging between the high stage compressor and the low stage compressor activation.

The system will go to bottom out temperatures.

Er09

Name:

Stuck Button

Description:

This condition indicates that the display board has a stuck button.

Response:

The Er09 will show on the display periodically.

Er11

Name:

Condenser Probe Sensor Failure

Description:

This condition indicates that the condenser probe sensor has failed to produce a valid reading for >12 consecu-

tive reads (~60 seconds).

Response:

The display shows “Er11”.

dErr

This is a general display error in which value being displayed can not be represented within characters provided.

(four dashes)
---- in display

Name:

Lost Communication

Description:

Communication between the micro board and the display board has beenlost. Under this condition, the visual

alarm flashes along with dashes in thetemperature display (----). Contact Technical Services.
