AK-CC55 Single Coil is optimised for control of one expansion valve + dierent combinations of light, rail heat and
alarm relays. It has 6 Digital Outputs (DO), known as DO1 – DO6, one Analogue Output (AO), known as AO1, 6
Analogue Inputs (AI), known as AI1 – AI6, an input that can be used as either DI1 (Digital Input) or AI7 (Sensor Input),
and 2 Digital Inputs, known as DI2 - DI3. AI7 (DI1) can be congured as S5B defrost sensor in application 1-6 and
application 9.
DO1 will be congured for a liquid line solenoid valve if the analogue output AO1 is congured for control of a
stepper valve driver.
Table 8: The controller covers the following nine applications:
Application 1-3
Plugin cabinets. Cabinets with dierent output combinations of alarm, rail heat and light.
Application 4
Remote cabinet including alarm, rail heat, defrost, light and fan.
Application 5
Remote hot gas defrost with suction, drain and hot gas valve.
Application 6
Back-to-back cabinet with one evaporator.
Application 7
Back-to-back cabinet with two evaporators.
Application 8
Cold storage room with defrost and simple humidity control.
Application 9
Custom
dened application, where the outputs can be congured according to custom requirements
