INPUT TIME AND DATE
Set day and time and if applicable Holidays through MAIN
MENU  CONFIGURATION MENU  DATE/TIME
CONFIGURATION. See the Controls Operation and Trouble-
shooting guide for details. Because a schedule is integral to the
chiller control sequence, the chiller will not start until the time
and date have been set.
NOTE: The date format is MM-DD-YY for English units and
DD-MM-YY for SI units.

*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 as required. The time and persistence settings on the CONF_ISM table
can be adjusted to increase or decrease the sensitivity to a fault condition. Increas-
ing time or persistence decreases sensitivity. Decreasing time or persistence
increases sensitivity to the fault condition.
Table 7 — Job Site Parameters
CONF_ISM — Select 0 for full voltage, 1 for reduced voltage, 2 for solid state, or 3 for free-standing variable
frequency drive.
CONF_ISM — Motor rated voltage from chiller information nameplate.
CONF_ISM — Enter ratio (reduced to a ratio to 1) of power transformer wired to terminal J3 of ISM. If no transformer is
used enter 1.
CONF_ISM — Per chiller nameplate data. RL AMPS on compressor nameplate.
CONF_ISM — Per chiller identification nameplate.
CONF_ISM — Enter value from nameplate in starter cabinet MAXIMUM FUSE. This value shall always be "9999" for
Benshaw RediStart MX3 wye-delta and solid-state starters.
CONF_ISM — Enter ratio (reduced to a ratio to 1) of current transformers wired to terminal J4 of ISM. This value shall
always be "100" for Benshaw RediStart MX3 and solid-state starters.
CONF_ISM — Current imbalance trip threshold. Enter up to 100% for starter type 3 (VFD).
CONF_ISM — Enter 0 if no ground fault CTs are wired to terminal J5 of ISM. Enter 1 if ground fault CTs are used.
CONF_ISM — Enter ratio (reduced to a ratio to 1) of ground fault CT.
CONF_ISM — ENABLE if motor protection required from drop in line voltage within one cycle.
CONF_ISM — Enter YES for 60 Hz or NO for 50 Hz.
CONF_ISM — ENABLE if motor protection required for drop in line frequency.
CONF_OPT — 1 = HGBP for Surge Correction; 2 = HGBP for Low Load Operation; 3 = Combination HGBP; 0 = no
HGBP or HGBP is Disabled.
CFGSURGE — Per job data — See modify load points section. Refer to table located in the control panel.
CFGSURGE — Chiller Requisition (TSmin, IGV min) or per job data — See modify load points section. Refer to table
located in the control panel.
CFGSURGE — Per Chiller Requisition (shapefac). Refer to table located in the control panel.
FACTORY — Enter water or brine.
CFGLIMIT — Usually 3°F (1.7°C) below design refrigerant temperature.
CFGLIMIT — Per Chiller Requisition if available or enter 50% of design pressure drop to 0.5 psi (3.4 kPa).*
CFGLIMIT — Per Chiller Requisition if available or enter 50% of design pressure drop to 0.5 psi (3.4 kPa).*
CFGLIMIT — Enter the maximum allowable value for condenser water pressure drop.
FACTORY — Enter value from chiller requisition form (product data submittal) if DEMAND LIMIT SOURCE is set to kW.

MODIFY CONTROLLER IDENTIFICATION IF NECESSARY
The module address can be changed from the Configuration
Menu. Change this address under CONTROL IDENTIFICA-
TION for each chiller if there is more than one chiller at the
jobsite. Write the new address on the HMI module for future
reference.
CONFIGURE SERVICE TABLES
Access the SERVICE tables through MAIN MENU CON-
FIGURATION MENU to modify or view the job site parame-
ters shown in Table . For details, see the 19XR with PIC 5 Con-
trols Operation and Troubleshooting guide.
