ICE Series Electrical System

Electrical Sequence for the ICE1400 Series Version 3, ICE1800 Series Version 3 and the ICE2100 Series Version 3 Cubers. (Manufactured from January, 2008)

ICE1400A/W3, 1800W3 and 2100W3 Electrical Sequence (Includes 50 hz. And 3 Phase)

1.Suction Pressure starts out at approx 60 psi and slowly drops to close the LP Control.

2.The LP Control energizes Relay Number 2 Coil.

3.Relay Number 2A contacts C and NO close to bypass the bin switches, Relay Number 2B contacts close and energize the timer.

4.The Timer times out and energizes Relay Number 1 Coil.

5.Relay Number 1A contacts C and NO close to send power to Cam Switch Number 2 contacts C and NC which energizes Harvest Motor 2, Hot Gas 2 and Relay Number 3 Coil.

6.Relay Number 1B contacts C and NO close to energize Harvest Motor 1 and Hot Gas 1

7.Relay Number 1B contacts C and NC open to de-energize the fan motors.

8.When the LP Control opens during hot gas, the circuit is latched through the Purge Switch contacts C and NC.

9.Relay Number 3A contacts C and NO close to send power to the Selector Switch and Hot Gas Valves when the curtain is open.

10.Once Cam Switch 2 contacts C and NO close (High Side of the Cam) it will remain energized from the Selector Switch until contacts C and NC close. (Rotates 360 degrees)

11.Once Cam Switch 1 contacts C and NO close (High Side of the Cam) the Harvest Motor will be energized and the Water Pump and Purge Valve will be de-energized when contacts C and NC open.

12.With the bin switches open, Relay Number 3 Coil de-energized due to Cam Switch 2 contacts C and NC closing, the unit will shut off on full bin.

Notes:

●C=Common

●NC=Normally Closed

●NO-Normally Open

●Relay Number 9 & 12=Common

●Relay Number 1 & 4=Normally Closed ●Relay Number 5 & 8=Normally Open

●The Fan Control on the air cooled model cycles only one fan. ●Relay 1, Puts unit into defrosts.

●Relay 2, Bypasses the Bin Switches and initiates the Timer.

●Relay 3, Bypasses the bin Switches during harvest when Relay 2 is de-energized from a rise in the suction pressure opening the Low Pressure Control.
