VLT Refrigeration Drive Instruction Manual
NOTE!
If the system requirement is to have the internal pack
controller for three compressors plus bypass valve
connected, there is the need to specify FC 103 with the
extra relay card (MCB 105) mounted inside the adjustable
frequency drive.
The bypass valve must be programmed to operate from
one of the extra relay outputs on the MCB 105 board.
This is needed because the standard relay outputs in the
FC 103 are used to control the compressors in the pack.
3.3.2 Required Initial Adjustable Frequency
NOTE!
If the wizard is run, ignore the following.
Adjustable frequency drives require basic operational
programming before running for best performance. Basic
operational programming requires entering motor
nameplate data for the motor being operated and the
minimum and maximum motor speeds. Enter data in
accordance with the following procedure. The
recommended parameter settings are intended for start-up
and checkout purposes. Application settings may vary. See
4 User Interface for detailed instructions on entering data
through the LCP.
Enter data with power ON, but before operating the
adjustable frequency drive.
