DRI-AIR INDUSTRIES, INC. DRYER OPERATION/ FEATURES 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.
DRI-AIR INDUSTRIES, INC. DRYER OPERATION/ FEATURES (Cont.) 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.

DRI-AIR INDUSTRIES, INC. DRYER OPERATION TROUBLE SHOOTING 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.
DRI-AIR INDUSTRIES, INC. Machine will not start: Power light is not on. DRYER OPERATION DETAILED DIAGNOSIS (PLC Controlled Dryer) For Micro Controlled dryers please see the Microprocessor Control Instruction Manual 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.
DRI-AIR INDUSTRIES, INC. 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.
