Figure 13 : Events Folder
The pages in the Events folder document up to the last 250 events that the
controller has experienced, and time stamps each. The events are recorded
in sequence, with number one being the newest and 250 being the oldest.
When a new event occurs, it becomes number one and all others are shifted
up in number.
The page numbers in the Title Bar are used to scroll through the events, with
each page displaying up to seven. Page one displays events one through six,
page two displays seven through twelve, and so on.
The following items will generate an event:
• Power ON
• Power OFF
• Press the Start Key
• Press the Stop Key
• Press the Load Key
• Press the Unload Key
• Warning
• Trip
• Start Inhibit
Active Warnings will be highlighted in amber while cleared Warnings will
have amber text.
Active Trips will be highlighted in red while cleared Trips will have red text.
Active Start Inhibits will be highlighted in blue while cleared Start Inhibits will
have blue text. The display will indicate the compressor is not ready to start if
a start inhibit is active.
See the following lists for details about messages in each type of event.
WARNING EVENTS LIST
•
Change Inlet Filter
Will occur if 1AVPT is greater than 0.7 psi vacuum (or 1.3 psi vacuum if the
high dust filter option is enabled) and the compressor has been fully loaded
for at least 8 seconds. This condition must exist for 3 seconds before the
warning is issued.
NOTE: Change Inlet Filter cannot be checked if the compressor is modulating.
•
Change Coolant Filter
This will occur if the compressor has been running loaded for at least 8
seconds, is warmed up, and the coolant filter pressure drop (5CPT - 6CPT)
is greater than 25 psi. This condition must exist for 150 seconds before the
warning is issued.
•
Sensor Failure
This will occur whenever sensors 4ATT, 5DTT, 6DTT, and 10APT are recognized
as missing or broken. The sensor failure message shall follow the following
format: SENSOR FAILURE 4ATT. The 5DTT and 6DTT sensor failures will be
shown only when the integrated dryer is installed (accessed in the factory
settings menu). The 10APT sensor failure will be shown only when the Enable
Remote Pressure is On. This failure will cause the controller to automatically
start using 4APT for loading and unloading the compressor. This condition
must exist for 3 seconds before the warning is issued.
•
Change Separator Element
Will occur if the compressor is loaded, the compressor is warmed up (the
injected coolant temperature is at least 120 °F), the package discharge
pressure is at least 90 psi, and the separator pressure drop is greater than
12 psi. This condition must exist for 3 seconds before the warning is issued.
•
High Airend Discharge Temperature
Will occur if the compressor is running and 2ATT is greater than 221 °F (97%
of 228) and the compressor is running. This condition must exist for
3 seconds before the warning is issued.
•
High Sump Pressure
If the compressor is running loaded, has been loaded for at least 8 seconds
and the sump pressure is more than 25 psi above the rated pressure for the
compressor. If this warning occurs, the online and offline pressures will be
reduced. For example, a rated pressure of 100 psi would have a maximum
offline pressure of 110 psi. This warning would occur if the sump pressure
goes above 125 psi in this example. This condition must exist for 3 seconds
before the warning is issued.
•
Auxiliary 1
This will occur if auxiliary input 1 closes. The contact must be closed for at
least 3 seconds before the warning will occur.
•
Auxiliary 2
This will occur if auxiliary input 2 closes. The contact must be closed for at
least 3 seconds and the Enable Control Power Loss setting must be off before
the warning will occur.
•
Service
Service warnings occur when the compressor has operated a certain number
of hours, based on the total hours. Service warnings can have multiple
levels, depending on the service level selection. A service level selection of 0
disables service warnings.
•
Service Level 1
If service level 1 has been selected for the compressor, a “SERVICE REQUIRED”
warning will be issued on hour intervals equal to the service time period set
point. This warning can be reset the same as any other warning.
•
Service Level 2
If service level 2 has been selected for the compressor, the service complete
factory set point will be used to clear a level 2 service warning and reset
the service time or date. The service complete can be reset before a service
warning occurs.
The initial “SERVICE REQUIRED” warning will occur at total hour intervals
equal to the service time period set point. However, 100 hours before this
a “100 HOURS TO SERVICE” warning will occur. This warning can be reset
the same as any other warning. One hundred hours later the “SERVICE
REQUIRED” warning will occur. This warning can be reset the same as any
other warning, however this warning will return in 24 hours if the service
complete factory set point has not be set. If the service complete has not
been set, 100 hours later, the “ALARM – SERVICE REQUIRED” warning will be
issued. This warning can only be cleared by the service complete factory
set point. Once the service complete factory set point is set, indicating the
service is completed, the time for the next “SERVICE REQUIRED” warning will
be calculated by adding the service time period to the total hours value, with
the “100 HOURS TO SERVICE” warning occurring 100 hours before and the
“ALARM – SERVICE REQUIRED” warning occurring 100 hours after that time.
