SECTION 8 – UNIT OPERATION

RETURN CHILLLED LIQUID SYSTEM LEAD/

LAG AND COMPRESSOR SEQUENCING

A lead/lag option may be selected to help equalize

average run hours between systems with two refrigerant

systems. This may be programmed under the OPTIONS

key. Auto Lead/Lag of the two systems based on average

run hours of the compressors in each system. Manual

Lead/Lag specifically selects the sequence in which the

microprocessor board starts the systems.

The microprocessor board will sequence compressors

load and unload systems according to Table 16. The

microprocessor will lead/lag compressors within each

circuit to maximize individual compressor run time

for the purpose of lubrication. It will also prevent the

same compressor from starting two times in a row. The

microprocessor board will not attempt to equalize run

time on individual compressors within a system.

Each compressor in a system will be assigned an

arbitrary number 1 or 2. The non-running compressor

within a system with the lowest priority number will

always be the next compressor to start. The running

compressor with priority number 1 will always be the

next compressor to shut off. Whenever a compressor is

shut off, the priority numbers of all compressors in each

system will be decreased by 1 with the wrap around.

This control scheme assures the same compressor does

not repeatedly cycle on and off.

Notes:
1. Step 1 is Hot Gas Bypass and is skipped when loading occurs. Hot Gas Bypass operation is inhibited during Pumpdown.
2. Step 3 is skipped when loading occurs.
3. Step 4 is skipped when unloading occurs.

1. Step is Hot Gas Bypass and is skipped when loading occurs. Hot Gas Bypass operation is inhibited during pumpdown. For Leaving Chilled

Liquid Control the Hot Gas Bypass solenoid is energized only when the lead compressor is running and the LWT < SP, the Hot Gas Bypass

solenoid is turned off when the LWT > SP + CR/2.

1. Step 1 is not used for loading or unloading.
2. Step 3 is skipped when loading occurs.
3. Step 4 is skipped when unloading occurs.
