Read this direction for safety first…
Some of the setting, size etc. on this manual could be changed without an advance notice.
Direction for safety
This direction is for using the product correctly so that you could be safe from danger or incident.
Please carefully keep this all direction.
Please use eighth being attached to a dual safety device in case of using for controlling instruments
which could be effective to human life or property(e.g. : Controlling atomic energy, medical
instruments ,cars ,trains ,flights ,burners, amusement instruments or safety machinery).
Please use with panel, there is a possibility getting an electric shock.
Do not inspect or test with connecting power.
Please connect after checking the terminal number when connecting power.
Do not reorganize except mechanic from ARSIN®
Do not use outdoor .It would be a cause making the product life shorter.
When connecting wires, please give a good screw on terminal. There is a possibility causing a fire with
bad connection.
Please use in the proper performance zone. If you don’t there is a possibility making the product life
shorter or, causing a fire accident.
Do not use a load which is exceeded proper value of opening and shutting capacity of a relay contact.
This will cause bad insulation, bad contact and bad connection.
When cleaning, water or liquid including oil or prohibited, only clean with soft and dried cloth.
Do not use in the place where there is inflammability gas, explosiveness gas, moisture a direct ray of
light, radiation, vibration and a shock.
Please prevent from getting a dirt or leftover wire inside of this product.
When connecting a sensor , please connect correctly after checking the polarity.

1. OUTLINE
AR1710 is based on Micro Processor and the most advanced equipment for controlling electricity
conducting efficient operation of a screw air compressor.AR1710 is a system managing the compressor’s
operation intensively, saving energy through controlling of timing for capacity adjustment, preventative
and maintenance schedule. In the other word,AR1710 conducts the best operation(control)according to
the condition set up and operating circumstance.
High reliability RISC MICOM
240×128 graphic LCD
Max. 30 events of running log storable (Non-volatile)-Easy preventative & maintenance and analysis for
trouble
Automatic calculation and notice function for preventative & maintenance ,consumable parts exchange
information and expected schedule
Automation of economical operation by embedded weekly timer
Unload Pressure: Pressure value under unload operation with closing intake valve on compressor.
Load Pressure: Pressure value under load operation with opening intake valve on compressor.
Auto Stop Delay: Compressor is stopped in case of continuous operation at unload operation during auto
stop delay time.
Stop Delay: Compressor is stopped after unload operation during manual stop delay time.
Start Delay: Delay time when compressor start load operation from starting.

1) Special advantages
AR1710 is a stable electronic control unit for screw air compressor which can provide users with running
log for integral control and management of the equipments. It adopts the method of digital process by high
efficiency RISC type microprocessor and occupies enough installation space and stability by unifying
module and control module. It provides convenience to let users know a status of operation at once
through display.
1-1) Noise solution
It is inevitable to figure for noise as an industrial controller. The digital input and output signal of AR1710 is
isolated, so it can not be allowed to flow external signal into the main board inside.CPU on main board
mounts HARDWARE WATCHDOG TIMER which can automatically recover from CPU down occurred by noise
per 32 msec., and BROWN-OUT function embedded in CPU inside supervises control power in real-time.
1-2) RISC TYPE MICOM
An assembler instruction in CPU can perform 7.3728Mbps, and logic for controlling written in CPU inside
needs about 1[m sec] based on 1 cycle. In this regard, sampling rate is about 10 times faster than the
existing controllers, so it has less probability of malfunction and more precise control.
1-3) Black Boxes: A recorder of operation status
It is possible for AR1710 to store maximum until 30 events of running log, so it is easy for preventative &
maintenance and Troubleshooting. Additionally, it is possible to verify the operation data at site occurs, so
it is helpful for users to know the reason of trouble and the status of equipment in real-time.
1-4) Display for operation status and/or maintenance (trip computer)
AR1710 has the display function for operation status, delay time and ready time by counting reversely, so
users can recognize the status of compressor at a glance. Also, it has the basic function to notify parts and
oil checking and exchanging schedule by calculating it automatically according to the information of
operation.
1-5) 240×128 graphic LCD (Wide Temperature Range Type: (-50 ~+150°C).Display part of AR1710 adopts
240×128 graphic LCD for user’s easy operation and recognition.
1-6) Minimization
It is possible to minimize compressor by occupying a small space due to unifying design of control part and
display part.
1-7) Scalability
It provides users with RS485 port, MODBUS RTU standard protocol and MMI software and automatic
interface.
