PARAMETER
ISM_CONF — Select 0 for full voltage, 1 for
Starter Type reduced voltage, or 2 for solid state or 3 for vari-
able frequency drive.
Motor Rated Line ISM_CONF — Motor rated voltage from chiller
Voltage information nameplate.
ISM_CONF — Enter ratio (reduced to a ratio to
Volt Transformer
1) of power transformer wired to terminal J3 of
Ratio
ISM. If no transformer is used enter 1.
Motor Rated ISM_CONF — Per chiller nameplate data. RL
Load Amps AMPS on compressor nameplate.
Motor Locked ISM_CONF — Per chiller identification name-
Rotor Trip plate.
ISM_CONF — Enter value from nameplate in
Starter LRA starter cabinet MAXIMUM FUSE. This value
Rating shall always be "9999" for Benshaw RediStart
MX3 wye-delta and solid-state starters.
ISM_CONF — Enter ratio (reduced to a ratio to
1) of current transformers wired to terminal J4 of
Motor Current
ISM. This value shall always be "100" for Ben-
CT Ratio
shaw RediStart MX3 wye-delta and solid-state
starters.
ISM_CONF — Current imbalance trip threshold.
Current% Imbalance
Enter up to 100% for starter type 3 (VFD).
Ground Fault ISM_CONF — Enter 0 if no ground fault CTs are
Current wired to terminal J5 of ISM. Enter 1 if ground
Transformers fault CTs are used.
Ground Fault ISM_CONF — Enter ratio (reduced to a ratio to
CT Ratio 1) of ground fault CT.
ISM_CONF — ENABLE if motor protection
Single Cycle
required from drop in line voltage within one
Dropout
cycle.
ISM_CONF — Enter YES for 60 Hz or NO for
Line Frequency
50 Hz.
ISM_CONF — ENABLE if motor
Line Frequency
protection required for drop in line
Faulting
frequency.
Surge Limit/Hot Gas OPTIONS — Enter 1 or 2 if HGBP is installed.
Bypass Option Enter 0 otherwise.
*With variable flow systems this point may be configured to the lower end of
the range.
NOTE: Other parameters: Screens are normally left at the default settings;
they may be changed by the operator as required. The time and persistence
settings on the ISM_CONF table can be adjusted to increase or decrease the
sensitivity to a fault condition. Increasing time or persistence decreases sensi-
tivity. Decreasing time or persistence increases sensitivity to the fault
condition.

VFD Field Setup and Verification

IMPORTANT: The VFD controller has been factory config-
ured for use and communications to the International Chiller
Visual Controller (ICVC). Some parameters are specific to
the chiller configuration and will need to be verified prior to
operation. Speed control and starting the drive have been
disabled at the VFD keypad. All command functions must
be initiated from the ICVC.
