Unit Start-up

96

RTHD-SVX02H-EN

Limit Conditions

UC800 will automatically limit certain operating parame-
ters during startup and run modes to maintain optimum
chiller performance and prevent nuisance diagnostic
trips. These limit conditions are noted in

Table 30

.

Table 30. Limit Conditions

Running -

Limited

The chiller, circuit, and compressor are

currently running, but the operation of

the chiller/compressor is being actively

limited by the controls. Further infor-

mation is provided by the sub-mode.

Condenser

Pressure Limit

The circuit is experiencing condenser pres-

sures at or near the condenser limit setting.

The compressor will be unloaded to prevent

exceeding the limits.

Low Evapora-

tor Refrigerant

Temperature

Inhibit

The circuit is experiencing saturated evaporator

temperatures at or near the Low Refrigerant

Temperature Cutout setting. The compressors

will be unloaded to prevent tripping.

Capacity Lim-

ited by Low

Liquid Level

The circuit is experiencing low refrigerant liquid

levels and the EXV is at or near full open. The

compressor will be unloaded to prevent trip-

ping.

Current Limit

The compressor is running and its capacity is

being limited by high currents. The current

limit setting is 100% RLA (to avoid overcurrent

trips).

Phase Unbal-

ance Limit

The compressor is running and its capacity is

being limited by excessive phase current un-

balance.

Seasonal Unit Start-Up Procedure

1. Close all valves and re-install the drain plugs in the

evaporator and condenser heads.

2. Service the auxiliary equipment according to the

start-up/maintenance instructions provided by the
respective equipment manufacturers.

3. Vent and fill the cooling tower, if used, as well as

the condenser and piping. At this point, all air must
be removed from the system (including each pass).
Close the vents in the evaporator chilled water cir-
cuits.

4. Open all the valves in the evaporator chilled water

circuits.

5. If the evaporator was previously drained, vent and fill

the evaporator and chilled water circuit. When all air
is removed from the system (including each pass),
install the vent plugs in the evaporator water boxes.

D

CAUTION

Equipment Damage!

Ensure that the oil sump heaters have been operating

for a minimum of 24 hours before starting. Failure to do

so may result in equipment damage.

6. Check the adjustment and operation of each safety

and operating control.

7. Close all disconnect switches.
8. Refer to the sequence for daily unit startup for the

remainder of the seasonal startup.

9. For the heat recovery unit, if chiller can’t start up by

low system differential pressure at low condenser
inlet water temperature. you cna increase the param-
eter in TU: Unit start time (max to 60 seconds).
