Bin Control Check - Hoshizaki DCM-300BAH Service Manual

D. Bin Control Check
When the actuator paddle is not engaged, BC circuit (CB K8 #3 (GY) and CB K8 #4 (GY))
is closed and the appliance produces ice. When ice fills the chute and engages the
actuator paddle, BC opens.
NOTICE! Do not place S1 dip switch 7 or S1 dip switch 8 out of the factory default
position. These dip switches must be left in the factory default position or the
appliance will not operate correctly. For details, see "III.C.1. Default Dip Switch
Settings."
• 2A4296-01: Dip switch 8 on; CB shuts down the appliance within 6 to 10 seconds.
• 2A8054-01 and 2A9093-01: Dip switch 8 and 9 on; CB starts the bin control
90-60 shutdown delay sequence after dip switch 8 bin control delay timer (6 to 10 sec.)
terminates. See "II.A.2.B. 2A8054-01 and 2A9093-01 90/60 sec. Shutdown."
