Fig. 30 — Hot Gas Bypass Option

Fig. 31 — Location of Hot Gas Bypass in 569J*12F

569J*12F with SVR Relays

With no thermostat demand, there will be no voltage at LVTB-A1;

HGBP SOLENOID is de-energized and solenoid valve remains

closed, preventing bypass vapor from the desuperheating tank to

enter the suction line at the compressor.
On a thermostat call for first-stage cooling, LVTB terminal Y1

is powered; when CADM1 is satisfied, compressor contactor

C1 and Solenoid Valve Relay SVR1 are energized. SVR1 con-

tacts close, providing 24-v to LVTB terminal A1, then through

HGBP RELAY NC contacts to HGBP SOLENOID. HGBP so-

lenoid valve opens, allowing bypass vapor from the desuper-

heating tank to enter the compressor suction port.
If thermostat calls for second stage cooling, LVTB terminal Y2

is powered; when CADM2 is satisfied, compressor contactor

C2, Solenoid Valve Relay SVR2 and HGBP RELAY are ener-

gized. HGBP RELAY NC contacts open, de-energizing the

HGBP SOLENOID; solenoid valve closes, blocking bypass

vapor from the desuperheating tank and unit runs at full cool-

ing capacity.
The model 569J*12F also includes the 32LT Motormaster low

ambient control as a standard feature. Refer to Appendix C for

information on the Motormaster control.

All Units

If either the Low Pressure Switch or High Pressure Switch

opens while thermostat output Y1 or Y2 remain energized, the

compressor contactor is de-energized, the compressor stops

and liquid line solenoid is de-energized (valve closes). CADM

initiates a TRIP event (cooling demand sensed at CADM ter-

minal Y but no current is measured at T1, T2, T3 motor sen-

sors); CADM relay opens and RED LED is illuminated. TRIP

condition maintains lockout of compressor operation until

CADM is manually reset. Reset CADM by cycling unit main

power.
