BACKUP REFRIGERATION UNIT

Refer to 748 System Schematic for refrigeration
and backup system. Refer to Refrigeration/Turret
Module Schematic for Dead Man Circuit diagram.

Normal Operation

The Refrigeration/Turret Module has a built-in
Dead Man circuit. When the Temperature Sensor
and the processor, on the Refrigeration/Turret
Module, are both functioning, the processor sends
a pulse to the Dead Man circuit. This causes the
Dead Man circuit to energize the Back Control
Relay. At the same time, the green Backup
Control LED will be lit to indicate the system is
functioning properly.

Backup Operation

If one of the following symptoms occurs the
Backup Control Relay will be de-energized. This
will transfer control of the refrigeration unit to the
Cold Control Thermostat.

1. The Refrigeration/Turret Module quits
functioning for about one minute.
2. The Temperature Sensor reads open or 5V for
about one minute.
3. If the 24 VDC or the Power Ground is lost to the
Refrigeration/Turret Module, the Backup Control
Relay will immediately be de-energized
