Description
Mapping Inhibited (LED)
Illuminates when the Microboard ACC function is not permitted to map points or
reduce speed due to unstable Leaving Chilled Liquid Temperature, manual speed
control, current limit in effect (chiller FLA only) or during Soft Shutdown. Otherwise, it
is extinguished.
Surge Avoidance Surge Detected
(LED)
Illuminates momentarily when a surge is detected by the Surge Protection feature.
This feature only detects surges that occur while the drive is running at maximum
frequency.
ACC Surge Detected (LED)

Description
VSD Start Frequency
Sets the starting frequency from which the ramp-up will begin. Programmable over
the following range:
•
0 Hz to 210 Hz (default 45 Hz)
Mapping Enable
Sets the Delta T (Leaving Chilled Liquid Temperature - Setpoint) needed to be met to
enable surge mapping and speed reduction initially on startup. Programmable over
the range of 0.5°F to 20.0°F (default 5.0°F).
Surge Margin Adjust
This value determines how close the frequency reduction will be allowed to get to
the surge line. Programmable over the range of 0.0 (default) to 25.0 Hz. Service
Technicians should refer to
Variable Speed Drive – Service Instructions (Form 160.00-M4)
prior to adjusting this setpoint.
Surge Sensitivity
Allows the Service Technician to adjust the sensitivity of the ACC Surge Detection in
the Microboard (surges that occur while the drive is running at less than maximum
frequency). Programmable over the range of 0.1 to 20.0 with default of 2.5. Smaller
values increase the sensitivity.
Surge Map Clear
Allows the Service Technician to clear the surge map. When this key is pressed, a
dialog box appears requesting a special password to proceed.
Surge Map Print
Allows the Service Technician to print the entire surge map to a connected printer, as
shown in
of this manual.
