Chapter 1 Preface
The H0U-88B1G controller is a general purpose industrial controller that
is designed with user programmable function. With the specific ACC
program provided by Inovance, you can realize smart control of screw
compressor. This manual describes the design and usage of the control
functions of the H0U-88B1G controller as well as ACC program.
The controller is easily installed and tested, highly reliable and cost
effective. The configured LCD supports display in both Chinese and
English, making the interface easy to understand.
The manual mainly introduces the function of our program designed for
screw air compressor control, which is suitable for MDI or Power-line
driving system.

Chapter 2 Functions and Configuration
2.1 Function overview
The H0U-88B1G with ACC program supports the following applications:
zIt can work together with the high-performance MD320 Series
inverter to form the electric and drive system of inverter-based
screw compressor.
zIt can be used for control of the screw compressor driven by
power-line supply.
zSupporting main motor and fan of screw compressor driven by
dual-MDIs respectively. The intake pressure and compressor
temperature can be kept constant through the built-in PID
operation.
zSupporting main motor and fan of screw compressor driven by
power-line. The MDI drive mode and power line drive mode can be
freely combined or switched online so as to maximize the system
reliability and control flexibility.
zSupporting detection of voltage, through which you can set
under-voltage protection, and detection of phase sequence through
which motor reverse rotation is prevented.
zMaking screw compressor begin to load after startup, and will not
stop the compressor until heat radiation completes in normal state.
It will immediately close all control outputs upon emergency stop.
zAuto Sleep function on the condition of less air consumption,
helping to save energy and lower equipment deterioration.
zOver-temperature alarm and over-temperature stop protection
functions.
zOver pressure protection function to ensure safety of user’s air pipe
network and devices.
zFault detecting, instant protection and alarm on temperature and
pressure sensors.
zAble to detect and display operating current of main motor and fan,

and separately set motor overload and lack-phase protection.
zAble to detect clog signals and give alarm.
z2-channel independent RS485 communication ports that can be
used for communication with host computer and the MDI,
respectively.
zAble to realize remote monitor by PC.
zMaintenance reminder 100 hours in advance according to
maintenance plans
zBuilt-in display in English and Chinese that can be switched online.
zConcise display interface without special learning or memorizing
requirements.
zDirect browsing of operating parameters and status of screw
compressor.
zSeamless connection with the MD320 Series inverter without the
requirement to manually set the inverter’s functional parameters.
zReal-time calendar.
zInquiry of 16 pieces of fault records and historical data. Each fault
record has related time stamp.
zMulti-level password protection for operator, agent (or owner) and
screw compressor manufacturer. Multi-level setting of parameters
according to displayed pages helps to prevent unauthorized
operation.

Chapter 3 Mounting and Wiring
3.1 Wiring the Controller
The H0U-88B1G controller is connected with the MD 320 Series
inverter using the RS485 signal twisted cables at the communication
ports (485A1 and 485B1).
Both contactor coil and solenoid valve are inductive components.
Electric spark will be produced between the contacts upon
switch-on/switch-off operation, which will incur magnetic interference
and influence the service life of the controller output contacts. Thus,
remember to connect RC absorption components to these components
in parallel. For details on connection, see the wiring diagram.
Figure 3-1 RC Absorption Component for Inductive Load
3.2 Drive Modes of Screw compressor
The screw compressor applies to the following drive modes through the
H0U-88B1G controller:
1˅Main motor: power-line drive (Y-Ƹstartup)
Fan: power-line drive
