The ARID-X dryer series is a dual bed design that provides a
constant supply of dry air to the material hopper. While one
bed is removing moisture from the process air the other is
regenerating by heating the desiccant to a high temperature.
Once the regenerated bed cools down, the Zone Valve
switches the airflow, and the newly regenerated bed is used to
desiccate the process air stream. The saturated bed is now
regenerated in the same manner, completing the regeneration
cycle. The cycle is depicted Page 8.
The airflow design of the ARID-X dryers makes the
regeneration cycle more efficient because we utilize a small
amount of the desiccated process air rather than ambient air
to regenerate the desiccant bed. This reduces the impact of
the high moisture content of the ambient air, which would
contaminate the desiccant bed, and allows the dryer to attain
a lower dew point. Please see the Air Flow Schematic on
Page 6.
HP4-X Design
Our patented HP4-X design incorporates 4 desiccant beds
where two are stacked, one over the other. This nearly
doubles the amount of desiccant available for drying the
process air stream, and because of the tower design, the
dryer is able to regenerate the desiccant in the same time as
our ARID-X series. This allows the dryer to operate in very
high humidity conditions without affecting the process air dew
point. In fact, this design produces dew point levels of – 40’ to
-80’ C for faster more complete drying of your material. Please
see the Air FLow Diagram on Page 7.
Hopper Design
Dri-Air’s ”all stainless” hopper design utilizes a stainless steel
inner shell surrounded by a stainless steel jacketed insulation
layer. The easily removable stainless steel spreader cone
promotes proper material flow to ensure that the material is
dried efficiently and no dried material is left at the hopper
bottom that needs to be fed out prior to operating. You must
ensure that your hopper is adequately sized for your usage
rate and is kept filled, to ensure that you have sufficient time to
dry the material.

Dryer Controls
The ARID-X series can be supplied with the standard PLC
Control Module or the advanced Microprocessor Control
Module, while the HP4-X series is only available with the
Microprocessor Control Module.
The PLC Control module includes a PLC control board,
display board, temperature controller and touch pad that is
programmed for the drying cycle described above. The
controller, display board and touch pad indicate the machine
status, alarms, set points and allow you to enter operational
settings for the dryer. These are explained in more detail later
in this manual.
The Microprocessor Control Module is one of the most
sophisticated yet operator friendly controls on the market. It
has many more features than the PLC control module that
provide the operator with more control and operational
flexibility with the dryer. These features and the operating
instructions are covered in detail in the Microprocessor
Control Instruction Manual included with your dryer.

The new Dri-Air Standard PLC and MICROPROCESSOR
Electrics were designed for quick diagnosis of problems.
The following steps should be done before proceeding with
other diagnostic steps.
1. Check the Power Circuit:
a. Incoming fuses or circuit breaker
b. All dryer fuses:
Each fuse, with the exception of the main fuses, has
a blown fuse indicator light that illuminates when the
fuse is blown.
c. Is power supplied to the unit?
d. Check heater continuity using a volt ohmmeter.
2. Compressed Air:
For those models that require compressed air.
a. Is compressed air connected with at least 60 PSI
b. Check water separator and drain if necessary
c. Pressure gage should read 60 PSI
3. Air Flow Circuit:
a. Ensure Zone Valve position corresponds to the
regeneration cycle by comparing the Zone position lights
on the Zone Valve to the ZONE position lights on the
dryerpanel.
b. Make sure that all hoses are connected, not crushed,
and free from obstructions.
c. Inspect filter and make sure cover is tight and the filter is
clean.
4. Control Circuit:
a. Using the PLC/MICRO Display Panel ZONE indicator
lights as a guide for the dryer regeneration cycle, check
that all inputs/outputs are proper for the part of the
regeneration cycle that the machine is in.
b. Monitor the PLC output lights to ensure the
corresponding LED on the power board is illuminated
and there is an output voltage to the heater.
5. Operating Conditions:
a. Check the process temperature. It should not be set
below 140°F (60°C) because the unit will go into high
temp alarm.

Machine will not start: Power light is not on.
1. Check circuit breakers (CB1) or incoming fuses inside
control box to see if they are tripped or blown. Reset
circuit breakers by turning them off and then on.
2. Check small fuses (FU1 & FU2) next to contactor. The
LED will be lit if they are blown. Replace if necessary by
opening the fuse holder and put new fuse into holder.
3. Check that incoming power to the unit is proper.
4. Check safety snap discs.

Main contactor is not pulling in.
1. Check the motor overload OL1 located in the panel. If it
is tripped, the window will show as orange/yellow. Reset
overload by pushing in the reset button.
Machine will not run: High Temp Alarm Light flashing:
This indicates that the temperature has exceeded the high
limit programmed into the temperature control or the set
temperature can not be reached.
Press stop and restart machine holding in the start button.
Monitor the actual temperature to see if it exceeds the set
point or can not reach the set point. If it can not reach set
point, see section below.
Machine will not run. High Temperature Alarm on, not
flashing:
1. This indicates an “open”thermocouple or the
temperature in the desiccant tower exceeded 900°F.
Machine will not reach temperature:
1. If the process heater light is not lit.
A.Check output from temperature controller and input to
PLC.
B.Check the thermocouple. The tip should be in the
middle of the hose.
2. If the process heater light is lit.
A.Check fuses on power board
B.Check solid state relays on power board.
C.Check that the air flow is correct.
D.Check blower rotation
E.Check heater for continuity.

DETAILED DIAGNOSIS
(PLC Controlled Dryer)
For Micro Controlled dryers please

Instruction Manual

DRI-AIRINDUSTRIES, INC.
OPERATING MANUAL - ARID-X, HP4-X 18-100 FM DRYERS
Revision 10/8/02 Page 15
Check the limit first by pressing the SET button on the
temperature control and holding until AL is displayed. The
setting shown indicated the amount over set point that the
alarm will be actuated. It is factory set to 50°F (30°C) and
should not be set below 30°F (16°C) or it will actuate too soon.
If the temp exceeds the set point check the following:
1. Remove the hose from the top of the hopper to check air
flow. There should be air flow out of the hopper with a
suction on the hose. If there is little or no flow, check the
inlet hose.
2. Inspect the filter to make sure that it is clean and not
affecting the air flow.
3. Check the power boards to see if one of the solid state
relays has failed on. Using an ammeter or voltmeter on
the output to the heater, see if there is power when the
LED is not lit which will indicate a failed relay.
4. Check the valve position.
The Dri-Air rotary valve is designed to provide very little flow
restriction and no leakage. It incorporates high temperature,
self adjusting seals for years of trouble free service. The
electrical controls are built into the end of the valve and
include position lights.
Trouble shooting is easy. If the lights indicating position do not
match the zone displayed on the control panel, or there are no
lights, the valve is not working properly. See if the cam is
actuating a switch.
DO NOT PUT FINGERS INTO VALVE WITH POWER ON
Check all electrical connections to make sure they are tight.
Contact factory with the serial number of the dryer for a
replacement valve.
