The applicable configuration tables are dependent upon the starter/
VFD type and manufacturer. For all factory unit-mounted equip-
ment all starter configurations should be completed at the factory,
but will need to be verified during chiller commissioning.
For starters without ISM, the appropriate starter selection must
be configured through MAIN MENU →CONFIGURATION
MENU→ FACTORY →VFD/STARTER OPTION.
Options are as follows:
0 = Starter with ISM
1 = Free Standing VFD with ISM [North America options:
Toshiba VFD, Allen Bradley PF7000, PowerFlex 700L (unit
mount)]
3 = Rockwell LF2 VFD (LiquiFlo2)
4 = Eaton VFD (LCX9000)
5 = Rockwell STD VFD (Allen Bradley PowerFlex 755)
7 = Danfoss VFD
8 = Benshaw Starter (Wye-delta or Solid State starters with MX3
(TM) and no ISM)
For constant speed machines verify all listed parameters in ISM
Configuration. Similarly, for unit-mounted VFDs verify all pa-
rameters listed in UM VFD Configuration Tables 8-11. Verify
against chiller electrical nameplates.
For units that are doing native communicating Modbus without
a UPC gateway ensure that the Modbus Gateway Option in
MAIN MENU→CONFIGURATION MENU→MODBUS
MASTER is changed to 0=Native along with baud rate and
Slave Device Address. Baud rate is typically 9,600 and slave
address is 1.
Liquid bypass option allows bypass of the economizer. When
Enabled and available the 19XR with frame C bypass valve
will modulate based on lift and % Amps to allow for high cool-
ing capacity at low load.
Dynamic Demand Limit is a control feature which will demand
limit the chiller to prevent refrigerant stack-up due to high re-
frigerant flow at low lift. It is required to set LCW at Selection
Point and LCDW at Selection Point as well as Enable the Dy-
namic Demand Limit function to make this feature active.
*With variable flow systems this point may be configured to the lower end of the range.

PARAMETER TABLE
AUTO RESTART OPTION CONF_OPT — Disable/Enable
SWIFT RESTART OPTION CONF_OPT — Disable/Enable
COMMON SENSOR OPTION CONF_OPT — Disable/Enable
EC/HG (HGBP) VALVE OPTION CONF_OPT — 0=No HGBP valve, 1= Continuous (two contactor control - one to open, one to close with
feedback of fully closed and open position), 2= on/off (1 contactor control - either on or off and no
feedback), 3 = mA (control by 4-20 mA signal with feedback)
EC/HG (HGBP) VALVE SELECTION CONF_OPT - 0 = Disable, 1=Surge (HGBP valve activates when surge prevention is high), 2= Low Load
(
EC valves activates based on IGV position and delta T for low load operation). EC valve is to Open when
IGV position is less than the configured ECV Open IGV1 Position and (cooling mode) the water Delta T
(ECW-LCW) is less than or equal to ECV On DT for Low Load minus ECV Low Load DB. EC valve is to
Close when IGV position is greater than the ECV Close IGV1 Position and (cooling mode) water Delta T is
greater than the ECV Off DT for Low Load plus ECV Low Load DB. 3=Combined (EC valves controlled by
both surge and low load algorithms)
HPR VLV OPTION Disable/Enable. When enabled, values for HPR VLV Delta Pos 0% (4 mA), HPR VLV Delta Pos 100% (20 mA),
HPR VLV Min Output (minimum output %), and HPR VLV Deadband can be set.
Typically HPR VLV Deadband must be set at 0.5 psig for normal operation.
TOWER FAN HIGH SETPOINT Default 75°F
REFRIG LEAKAGE OPTION Disable/Enable
OIL COOLER EXV OPTION Disable/Enable
CUSTOMER ALERT OPTION Disable/Enable
ICE BUILD OPTION Disable/Enable
VAPOR SOURCE SV OPTION Disable/Enable
VAPOR SOURCE SV DELAY Default 5 min
EVAP LIQUID TEMP OPT Disable/Enable
EVAP APP CAL SELECTION 0 = Saturation Temp, 1 = Refrigerant Temperature
