1.0 Basic Operation
1.1 Description of Controller Interface
The ES08-15 controller features a 7-inch LCD full-colour, touch screen display as the human-machine
interface.
The controller is always switched on and active whenever the compressor set is energised from its electrical
power supply. It is operated by touching the displayed icons on the screen with a fingertip or stylus pen tip.
An automatic screen-saver function switches off the display after two minutes of inactivity. The display can
be reactivated by a single touch.
The controller should be provided with weather protection against precipitation and direct sunlight. Keep the
screen clean and dry. If necessary, use a proprietary LCD screen cleaning solution and a soft anti-static,
scratch-free cloth to remove any dust and fingerprints. Do not use harsh solvents or abrasive cleaners.
1.2 Password Security
A three-tiered system of passwords is used to safeguard the controller’s settings and records.
The lowest-level User password is: C456
The mid-level Service password is made available to compressor service technicians upon request.
The highest-level Factory password is reserved for use by the manufacturer.
1.3 Controller Screens Map
A hierarchical systematic view of the interface screens that are accessible via the controller is shown in
Figure 1.1.

recommendations:
a) Do not operate the compressor with any of its maintenance access panels open or removed.
b) Before opening or removing any of its maintenance access panels or performing any maintenance
work on the compressor or connected pneumatic system: Switch off the unit; isolate and tag-out the
power supply; carefully release the residual air pressure from the internal piping and any external air
receiver tank and connected piping; and close the air outlet valve.

Warning: The compressor set’s built-in schedule function allows it to be switched on and off automatically
according to the preset timer(s). This feature does not include provision for any alarm or annunciation that
the unit is about to start or stop. The schedule function should therefore NOT be used unless the person
conducting a business or undertaking involving the management or control of the plant has first implemented
at least the following risk control recommendations:
a) Do not operate the compressor with any of its maintenance access panels open or removed.
b) Before opening or removing any of its maintenance access panels or performing any maintenance
work on the compressor or connected pneumatic system: Switch off the unit; isolate and tag-out the
power supply; carefully release the residual air pressure from the internal piping and any external air
receiver tank and connected piping; and close the air outlet valve.
Note: Reducing the differential between the start and stop pressures will increase the on and off cycling
frequency of the compressor modules. This may cause the permissible number of air-end drive motor starts
per hour to be exceeded, which will trigger a shutdown alarm for the affected motor(s). Refer to the
Instruction Manual for guidance about the pressure differential and recommended air receiver tank volume.

a) Do not operate the compressor with any of its maintenance access panels open or removed.

Note: To utilise the single contact remote control function, connect one latching switch between terminals
24G and X06 on Terminal Board 1 (TB1) inside the compressor’s electrical cabinet. Closing this 24 V DC
control circuit by means of the switch will send an “on” or “start” signal to the controller and opening the
circuit will send an “off” or “stop” signal. The compressor’s on or off status can be ascertained visually by
checking the two-position remote-control switch or an indicator light wired into this circuit.
It is recommended to use the single contact option for remote control operation.
Note: To utilise the double contact remote control function, connect one non-latching switch between
terminals 24G and X06 for the “start” command and another non-latching switch between terminals 24G and
X07 for the “stop” command. Momentarily closing either of these 24 V DC control circuits by pulsing one
switch or the other will send the relevant “on” (i.e. “start”) or “off” (i.e. “stop”) signal to the controller.
Note: Neither the single nor double contact remote control functions are compatible with sequential control
operation of multiple compressor sets. Only a single standalone compressor set can be operated by remote
control.
Note: Incorrect rotation of the drive motor will cause permanent damage to the compressor air-end that is
not a warrantable fault. Ensure that the 3-phase electrical power supply is connected with clockwise red →
white →blue phase sequence rotation BEFORE starting the compressor. When using the main motor test
function after carrying out any electrical installation, maintenance or repair work, visually check and confirm
that each drive motor and air-end is rotating COUNTER-CLOCKWISE when viewed looking onto its drive
shaft.
Note: When using the fan motor test function, check and confirm that the fan discharges upwards and away
from the cooling air exhaust vent on top of the compressor set. Temporarily affixing a piece of A4 paper with
adhesive tape along one long edge only above the vent can provide reliable indication of the cooling airflow’s
direction.
Note: Increasing either the stop delay or stop interval above the recommended 2-second value may cause
nuisance activation of the discharge air pressure shutdown alarm.
2.7 Calibration Menu
The calibration menu is accessed via the system menu using either the service or factory passwords. The
set values should NOT be altered without first seeking guidance from the manufacturer. The calibration menu
screen is shown in Figure 2.7.
