INSTALLATION AND COMMISSIONING Medium Flow Compressed Air Dryers - IOMI.
INSTALLATION AND COMMISSIONING Only competent personnel trained, qualified, and approved by Parker Hannifin should perform installation, commissioning, service and repair procedures. Warning COMMISSIONING CHECK LIST TICK WHEN TASK PAGE COMMENTS Recommended System Layout System Components / piping installation Locating the Equipment...
Page 19
RECOMMENDED SYSTEM LAYOUT CDAS HL / OFAS HL / FBP HL dryers can be installed directly after an air compressor or downstream of a wet air receiver. The preferred method of installation is downstream of a wet air receiver as the air receiver acts as a pre-cooler / liquid separator and is effective at protecting the dryer from bulk liquid contamination and small temperature spikes.
LOCATING THE EQUIPMENT Environment The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature, humidity, and airborne pollution will affect the environment in which the equipment is operating and may impair the safety and operation.
Page 21
SIDE MOUNTING THE REAR PANEL For installations where space is limited (for example if the dryer is placed against a wall), it maybe beneficial to install the rear panel assembly to the side of the dryer to provide easier access to the electrical control box, dewpoint sensor & control valves. Important Notes: •...
Page 22
Securing the Dryer Mounting holes are provided in the feet of the dryer. Once the dryer has been positioned in its final location ensure that it is securely fixed in place using M15 fixing bolts. Attach the Exhaust Silencer The dryer is supplied with an exhaust silencer. If the dryer is to be located in a noise sensitive area, exhaust air can also be remotely piped away.
ELECTRICAL INSTALLATION A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local regulations. Warning During installation and commissioning, the controller must be connected to a suitable power supply and configured using the dip switches found on the main control board.
Page 24
Configure Inlet Valves Configuration (N/C - Normally Closed or N/O - Normally Open) • Default Factory Setting is Normally Closed. • If a dryer is required to operate in a Normally Open configuration, reconfigure Dipswitch Array 1, DIL Switch 7 as shown: DIPSWITCH ARRAY (1) DIL SWITCH FUNCTION...
Commissioning – Controller Setup Advanced Installation To access the additional functionality offered by the controller, the following settings must be activated and configured to match the requirements of the installation: Remote Stop / Start (Refer to page 25) • Dipswitch configuration required •...
Remote Stop / Start Connection CDAS HL / OFAS HL / FBP HL dryers can be configured to enable remote shut down and start up (Stop / Start) of the dryer. This requires a 24VDC signal to be supplied to the remote stop digital input (RC) on the control board and setting of DIL Switch 8 on Dipswitch Array 1 to enable DIPSWITCH ARRAY (1) DIL SWITCH...
Important Notes: • The default inlet valve configuration for CDAS HL / OFAS HL / FBP HL is Normally Closed (N/C). • In this configuration, when the remote switch is closed and the ½ cycle is completed, the inlet and exhaust valve will be closed. There will be no air flow through the dryer, protecting the desiccant bed.
Page 28
Purge Economy Operation Compressor On Load As the compressor is operating, the relay connection is open and the dryer will be operating normally, drying the compressed air. Compressor Off Load When the air compressor reaches its set operating pressure and goes off load, the relay in the compressor will close.
Page 29
Remote Alarm Connection – General Fault Alarm The CDAS HL / OFAS HL / FBP HL dryer controller includes a general fault alarm used to indicate power loss, dewpoint alarm or dewpoint sensor failure. When the general fault alarm is active, an icon will be visible on the display. The general fault alarm is linked to a relay providing volt free contacts: Normally Closed (N/C), Normally Open (N/O), and a Common (Com) These contacts are rated 24Vdc and 230Vac @ 1A and can be used for remote alarm indication.
Page 30
Remote Alarm Connection - Dedicated Dewpoint Alarm The CDAS HL / OFAS HL / FBP HL dryer controller includes the ability to connect a dedicated dewpoint alarm relay that will activate only if a dewpoint alarm occurs. This function requires the connection of an additional relay (not supplied) and activation by a trained engineer using the ADS service software.
CDAS HL / OFAS HL / FBP HL controller PCB. HYGROMETER Connection of the 4-20mA retransmission is identical for both the Parker Dewpoint Sensor (PDS) and Hygrometer. An 800Ω (+20 Ω / -0 Ω) resistor will be required in series in the loop circuit.

After changing any parameters, the control board must be power cycled (Power off / Power On) for the changes to be accepted. To change the baud rate on the CDAS HL /OFAS HL / FBP HL dryers it is necessary to connect the dryer to a PC using the Parker ADS service software to communicate with the control board.

CDAS HL OFAS HL FBP HL OPERATION Medium Flow Compressed Air Dryers - IOMI.
Page 38
OVERVIEW OF OPERATION CDAS HL / OFAS HL / FBP HL purification systems are based around a heatless adsorption dryer and associated pre filtration and post filtration. Adsorption dryers are designed for the treatment of water vapour only and therefore require pre-treatment of the incoming compressed air to operate correctly and protect the adsorbent desiccant bed.
Page 39
CDAS HL / OFAS HL / FBP HL OPERATION CDAS HL / OFAS HL / FBP HL Dryer Cycle Times and Operation CDAS HL / OFAS HL / FBP HL dryers are designed to use two drying columns to deliver a constant outlet dewpoint. A full cycle is the time it takes the dryer to fully utilise the desiccant material in both columns.
Page 40
Important Note: Purge air volume must be set up during commission to supply the correct amount of purge air required for efficient regeneration. Refer to page 21 for purge volume setting. Re-pressurisation (30 seconds) After 150 seconds (2 ½ minutes) of regeneration, the exhaust valve will close, and the purge air will re- pressurise the off-line column.
Page 41
Seconds Important Notes: Should an error occur with either the Parker Dewpoint Sensor (PDS) or the Dewpoint Hygrometer, a yellow box will appear around the dewpoint icon. The outlet dewpoint figure will be replaced with “---“and “ERR” will be displayed.
Page 42
3 half cycles can be modified by a trained engineer (please note, that changing these parameters can affect the performance of the dryer and should only be carried out following consultation with Parker) Purge Economy Purge economy requires a physical connection between the air compressor and the dryer and is designed to save energy (by stopping purge air) when the air compressor goes off load.

Dewpoint Alarm Delay at Start Up Following application of power there is a dewpoint alarm delay of 30 minutes (customisable by a trained engineer using the Parker ADS service software). During the alarm delay period, should the dryer outlet dewpoint be worse than the dewpoint alarm setpoint, the alarm relay will not be triggered.
