4. start-up & operation - standard controller
Do not allow the unit to ow air unless switched on and cycling.
Resulting effect could be desiccant contamination; requiring a desiccant service.
• Ensure all pipe work is connected as per the typical layout
• The unit is connected with a power supply as stated on the rating label.
• Ensure the inlet air pressure is with in limits as stated on the rating label on the product.
• Ensure the inlet air temperature is with in limits as stated on the rating label on the product.
• Slowly open the inlet ow and allow the unit to pressurize
• Turn on the power to the unit, the unit will display its’ status.
• Allow the unit to cycle at least 2 times before slowly opening the outlet ow.
• In case of using the Remote Start/Stop function, ensure external voltage is active.
This unit must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape
wire for the electric current. This unit is equipped with a cord having a grounding wire with an appropriate grounding plug.
The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do
not modify the plug provided; if it does not t the outlet, have the proper outlet installed by a qualied electrician.

4.1 remote start/stop control - standard controller
To gain access to the remote start/stop feature:
• Turn to unlock latch & open front door
• Locate ying lead at bottom of controller
• Remove the insulation from the ying lead
• There are six wires; 1. Brown Wire - 24V DC Output
2. Blue Wire - 24V DC Output
3. Black Wire - Remote Start/Stop Input
4. White Wire - Alarm Input (Zero volt contact)
5. Green Wire - Alarm Output (Zero volt contact)
6. Red Wire - Remote Stop Input
• To set up the Remote Start/Stop control, remove/break the connection between the Brown and Black wires and connect
externally to a remote switch or relay.
• A 24V DC Output must be connected to the Black wire to enable the dryer to operate, if the connection is broken or if there is
no voltage the dryer will switch off and revert to standby mode, displaying “REMOTE STOP ACTIVE” on the controller display.
Under no circumstances should an external voltage or current be applied to any of these wires, as damage to
the control system will occur, negating the warranty.

4.3 shutdown procedure - standard controller
Isolate unit from compressed air system.
The unit will still be pressurized
Ensure the unit is fully depressurized and isolated
To fully depressurize, following the steps below;
• Cycle the dryer at least twice to ensure the unit exhausts and is completely depressurized.
• When fully depressurized the ‘clicking’ of the exhaust valves will be heard but no air exhausted.
• When the unit is fully depressurized, isolate from the electrical supply.

4.4 monitoring dryer performance (when ES option is tted)
- standard controller
The pressure dew-point is displayed on the display of the control panel. When the dew-point displayed is equal to or better than -40°C
(-40°F) PDP the dryer will switch into energy saving mode and stop cycling, resulting in zero purge, but no interruption in ow. When
the dew-point degrades to -39°C (-40°F) or higher, then the dryer will restart cycling ensuring the dew-point is maintained at or better
than -40°C (-40°F).
If during normal operation, the unit fails to achieve dew-point (degrades above -30°C (-22°F )) the dewpoint alarm output will be
indicated on the front screen and the remote alarm output will activate.
The set levels for the ES and dewpoint alarm are adjustable and can be accessed by carefully removing the front bezel to expose the
PLC and adjustment buttons.
Hold buttons A & B down for 8 seconds to access the menu shown on page 17 display 8.
Adjusting Dewpoint Settings - Standard controller
Hold down button 1 and button 3 for ve seconds
In the DEWPOINT SETTING menu, hold down the white button until the word ‘Param’ appears
at the bottom of the screen
Press button 4 once. The text will change to ‘Prog’.
The ‘ES SETPOINT’ line will begin to ash.
Using the buttons, adjust the ‘ES SETPOINT’ or ‘DWPNT ALARM’
Button 1 is used to move up a line.
Button 4 is used to move down a line.
Button 2 is used to lower the value
Button 3 is used to increase the value.
Following any changes to the conguration, it is essential that the program is reverted back to
‘Param’.
Hold down the white button until ‘Prog’ is displayed at the bottom of the screen
Once ‘Prog’ appears, press button 4 once. The text will change back to ‘Param’.
Beware, this is only an illustrative example.

1 Power-up Display (only visable on power start-up for 10 seconds)
During power-up the screen will display:
Program number followed by the version
Total hours the product has operated
This screen can be displayed at any time by pressing and holding buttons 1 & 2 for
two seconds
2 Normal Operation Display

Column ‘A’ and ‘B’ status, this will show as one of three sequences:
ONLINE - column is owing
PURGE - column is regenerating
READY - column is waiting to switch
Hours the dryer has run between services
3 Service Re-set Display
When due a service, the product display will show ‘SERVICE REQUIRED’.
After servicing the product, you will be required to reset the service hours run
counter. When a magnet is held to the specied area on the dryer shroud for 10
seconds, the screen will display ‘SERVICE
RE-SET’. The hours run counter will revert back to zero.
4 Normal Operation Display (ES Models)
During normal operation of an ES enabled product, the screen will constantly disply
the updated pressure dewpoint reading. This can be displayed in either degrees
celcius or degrees fahrenheit, depending on how the controller is congured.
Speak to the manufacturer about your requirements

5 Energy Saving Mode Active Display (ES Models)
While energy saving mode is active the screen will display:
• Column ‘A’ status and Column ‘B’ status, this will be shown as;
• ONLINE; this column is owing
• ‘ENERGY SAVING MODE’
• Hours the dryer has run between services/hours in ES mode
•
Constantly updated dew-point reading, this can be displayed in either
degrees celcius or degrees fahrenheit.
6 Dew-point Sensor Fault Display (ES Models)
If a fault occurs with the dew-point sensor or the connection to the dew-point
sensor, the screen will display;
• Column ‘A’ status and Column ‘B’ status
• Hours the dryer has run between services/hours in ES mode
• ‘DEWPT SENSOR FAULT’
7 Dew-point Alarm Display (ES Models)
If the dew-point sensor reading falls below the desired alarm limit the screen will
display;
• Column ‘A’ status and Column ‘B’ status
• Hours the dryer has run between services/hours in ES mode
• ‘DEWPOINT ALARM’
8 Energy Savings Adjustment Display (ES Models)
When adjusting the ES set-point the screen will display;
‘ES SETPOINT’ - This is the point at which the dryer activates ES mode. If the
dewpoint is less than the ES set-point, ES mode activates. If the dewpoint is
greater than the ES set-point, ES mode deactivates.
‘DWPNT ALARM’ - this is the point that the dryer will activate the dewpoint alarm
and remote alarms.
‘ES OVERRIDE’ This is the maximum time in minutes that ES mode is continuously
active before the dryer switches columns and performs a regeneration cycle.
