MODIFY EQUIPMENT CONFIGURATIONIF NECES-

SARY— The Equipment Conﬁguration table has tables to

select and view or modify.Carrier ’scertiﬁed drawings will

havethe conﬁguration values required for the jobsite. Modify

these tables only if requested.

ConﬁgTable Modiﬁcations — Change the values in this table

per job data. See certiﬁed drawings for values. Modiﬁca-

tions include:

• chilled water reset

• entering chilled water control (Enable/Disable)

• 4-20 mA demand limit

• auto. restart option (Enable/Disable)

• remote contact option (Enable/Disable)

Owner-ModiﬁedCCN Tables— The following tables are de-

scribed for reference only.

Occdef Table Modiﬁcations — The Occdef tables contain

the Local and CCN time schedules, which can be modiﬁed

here, or in the Schedule screen as described previously.

HolidefTable Modiﬁcations — The Holidef tables conﬁgure

the days of the year that holidays are in effect.See the holi-

day paragraphs in the Controls section for more

details.

Brodefs Table Modiﬁcations —The Brodefs table deﬁnes

theoutside-air temperature sensor and humidity sensor if one

is to be installed. It will deﬁne the start and end of day-

light savings time. Enter the dates for the start and end of

daylight savings if required for the location. Brodefs also

will activate the Broadcast function which enables the holi-

day periods that are deﬁned on the LID.

OtherTables — The Alarmdef, Cons-def, and Runt-def con-

tain tables for use with a CCN system. See the applicable

CCN manual for more information on these tables.

These tables can only be deﬁned through a CCN Building

Supervisor.

CHECKVOLTAGESUPPLY —Access the Status 01 screen

andread the actual line voltage. This reading should be equal

tothe incoming power to the starter. Use a voltmeter to check

incoming power at the starter power leads. If the readings

are not equal, an adjustment can be made to the 24-v input

to the SMM at the potentiometer located in the low-voltage

section to equalize the two readings.

PERFORMAN AUTOMATEDCONTROL TEST — Check

the safety controls status by performing an automated con-

trols test. Access the Control Test table and select the

Automated Testsfunction (Table 8).

The Automated Control Testwill check all outputs and

inputs for function. It will also set the refrigerant type. The

compressormust be in the OFF mode in order to operate the

controlstest and the 24-v input to the SMM must be in range

(per line voltage percent on Status01 table). The OFF mode

iscaused by pressing the STOP pushbutton on the LID. Each

test will ask the operator to conﬁrm that the operation is oc-

curring, and whether or not to continue. If an error occurs,

the operator has the choice to try to address the problem as

the test is being done, or to note the problem and proceed to

the next test.

NOTE: If during the Control Test the guide vanes do not

open, check to see that the low pressure alarm is not active.

(This will cause the guide vanes to close).

NOTE: The oil pump test will not energize the oil pump if

cooler pressure is below –5 psig (–35 kPa).

Whenthe test is ﬁnished, or the EXIT softkeyispressed,

the test will be stopped and the Control Testmenu will be

displayed. If a speciﬁc automated test procedure is not

completed, access the particular control test to test the func-

tion when ready. The Control Test menu is described as

follows:

Automated Tests As described above, a complete

control test.

PSIO Thermistors Check of all PSIO thermistors only.

Options Thermistors Check of all options boards

thermistors.

Transducers Checkof all transducers.

Guide VaneActuator Check of the guide vane operation.

Pumps Check operation of pump outputs,

either all pumps can be activated,

or individual pumps. The test will

also test the associated input such

as ﬂow or pressure.

Discrete Outputs Activation of all on/off outputs or

individually.

Pumpdown/Lockout Pumpdown prevents the low refrig-

erant alarm during evacuation so

refrigerant can be removed from

the unit, locks the compressor off,

and starts the water pumps.

TerminateLockout Tocharge refrigerant and enable

the chiller to run after pumpdown

lockout.

Refrigerant Type* Sets type of refrigerant used:

HCFC-22 or HFC-134a.

*Makesure to Attach to Local Device after changing refrigerant type.

Refer to Selecting Refrigerant Typesection on page 50.

CheckOptional Pumpout System Controls and

Compressor— Controls include an on/off switch, a 3-amp

fuse,the compressor overloads, an internal thermostat, a com-

pressorcontactor, and a refrigerant high pressure cutout. The

high pressure cutout is factory set to open at 220 ± 5 psig

(1250 ± 34 kPa), and automatically reset at 185 + 0,

−7 psig (1280 +0,–48 kPa) with HCFC-22. HFC-134a units

openat 161 psig (1110 kPa) and reset at 130 psig (896 kPa).

Check that the water-cooled condenser has been connected.
