Status Meaning and 8-LED Bar Indication
• The COR driver is operating normally and is communicating with the APEX
system. If a COR-20 is being used in standalone mode, this also indicates
normal operations.
• The number of LEDs lit on the 8-LED bar indicates the current pump speed.
There are 16 speed levels when in standalone mode.
• The COR driver is in fallback mode and is attempting to communicate with
an APEX base unit.
• The number of LEDs lit on the 8-LED bar indicates the current pump speed.
• The COR pump has been manually turned OFF using the left COR button or
by using the COR tile on the APEX Classic, APEX Local, or APEX Fusion
dashboard.
• None of the small LEDs will be lit.
• One of these three conditions exist:
o FeedA has been activated using the right COR button
o FeedA has been activated through the APEX
o The COR driver is in Minimum Speed Calibration Mode
• The number of LEDs lit on the 8-LED bar indicates the current pump speed
• The COR driver is in Maximum Speed Calibration Mode
• The number of LEDs lit on the 8-LED bar indicates the current pump speed
• An error condition exists. When the status LED is red, one of the LEDs of 8-
LED bar will flash to indicate the specific issue detected.
o The COR driver has detected an overcurrent condition (LED #1, #4,
or #5 may be flashing) This may indicate that the pump’s intake is
