a) Power Switch "ON," Rail Cooling Switch "OFF"

Cabinet temperature at or above setpoint: CabFM, CLLV, and PH energize. The

2 minute Comp delay timer and 6 hour DT start.

b) Power Switch "ON," Rail Cooling Switch "NORMAL" or "LOW"

Cabinet temperature and rail temperature at or above setpoint: CabFM, CLLV, PH,

RailFM, and RLLV energize. The 2 minute Comp delay timer and 6 hour DT start.

2. Cool Down

a) Power Switch "ON," Rail Cooling Switch "OFF"

CabFM, CLLV, and PH continue. The 2 minute Comp delay timer expires and Comp

and ConFM energize.

b) Power Switch "ON," Rail Cooling Switch "NORMAL" or "LOW"

CabFM, CLLV, PH, RailFM, and RLLV continue. The 2 minute Comp delay timer

expires and Comp and ConFM energize.

a) Power Switch "ON," Rail Cooling Switch "OFF"

CTh reaches 3.6°F (2°C) below setpoint. CabFM and PH continue, Comp and ConFM

de-energize. CLLV de-energizes for 2 seconds (CLLV then remains energized during

Comp off time).

b) Power Switch "ON," Rail Cooling Switch "NORMAL" or "LOW"

CTh, RTh, or both have reached 3.6°F (2°C) below setpoint.

(1) Cabinet still cooling, RTh reaches 3.6°F (2°C) below setpoint
